Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
Exercise indices that comprehensively consider mental and physical strength and indicate the exercise intensity of training necessary to increase the endurance of the whole body, and exercise indices that indicate the exercise intensity for making pace in the competition The present invention relates to a method and an apparatus for measuring an exercise index for notifying in consideration of an altitude difference in the exercise.

[0002]

2. Description of the Related Art Generally, a person who exercises (subject)
If the exercise intensity at that time can be known, exercise according to the exercise prescription and various types of training can be performed. In particular, in various competitions, knowing the intensity of exercise at a certain point in time will make it possible to determine how much the intensity is in comparison with the appropriate intensity of the exercise. This will give you the information you need to make decisions, and will also help you to win the competition. Here, there are various methods for expressing exercise intensity, but when roughly classified, a method using physical indexes such as power and exercise pitch of the exercise and a physiological index such as pulse rate are used. And divided into methods. For example,
When the exercise form is a traveling exercise, a proportional relationship is established between the physical exercise intensity and the traveling speed, so that the physical exercise intensity and the traveling pitch can be represented by using an index such as a traveling index or a traveling index. . Further, by detecting the number of beats during running, the exercise intensity can be expressed using a physiological index such as an intensity of 150 [beats / minute].

On the other hand, even if exercise intensity is not required, when performing exercise, some subjective evaluation (for example,
Since the subject is "tight" or "easy", it is very common for the subject to judge the exercise intensity at that time based on his own subjective evaluation and perform various types of training. For example, maximal oxygen uptake has been improved by exercising at an intensity that is tight and mentally affordable ("About the Ministry of Health and Welfare's" Exercise requirements for health promotion "): Munehiro Shindo: Health Sciences 3
Vol. 2, No. 3, 1990).

[0004] In addition, the subject should grasp his or her own athletic ability and exercise at an intensity suitable for the athletic ability. However, even if the subject exercises at the same intensity, the subject depends on the physical condition and exercise conditions at that time. The burden on the body is usually different. For this reason, for example, as in the technique described in Japanese Patent Application Laid-Open No. H8-10234, the subject is caused to exercise under a certain condition using a treadmill, and the physical strength of the exercise and the blood flow of the subject are measured. Exercise and the like have been performed while measuring physiological indices and monitoring the intensity during exercise.

[0005]

By the way, the exercise intensity represented by the above-mentioned physical index only quantitatively indicates the intensity of the physical exercise of the subject at that point in time. It does not comprehensively consider mental and physical strength. In addition, the exercise intensity represented by the physiological index does not take into account the physical strength of the subject even though the physical strength of the subject may be considered. On the other hand, the exercise intensity obtained by the subjective evaluation is not tied to the physical strength and the mental strength of the subject in the first place. For this reason, even when exercising at the intensity determined by the subjective evaluation, there are many cases in which the intensity is too strong to overdo it, or conversely too weak to have no training effect.

Further, the technique described in the above publication has a drawback that the exercise performed by the subject is limited to the exercise using a treadmill, and the intensity of other exercises cannot be measured. In addition to such treadmills, there are bicycle ergometers and other devices that provide a certain level of exercise, but as a practical matter, only a small number of those who can use such treadmills and bicycle ergometers at their own discretion are free to use. Not only those who exercise, but also places to exercise are limited to places where exercise equipment is installed.
For this reason, there is a problem that the technique described in the above-mentioned publication cannot be applied to a case where the user exercises while monitoring the exercise intensity on a commonly used course, a general road, a park, or the like. Moreover, such locations are generally not flat, but are usually sloped, even if they are maintained. Here, when the exercise form is running (running), when the stride in the running exercise becomes a steep slope,
It tends to be shorter than that of a flat road, and conversely, it tends to be longer when going downhill. In addition, since the tendency to increase momentum on a downhill is strong, the subject often cannot be conscious of the running state of the downhill. For this reason, especially when the descending gradient is continuous, the stride becomes longer even if the pitch is kept constant. As a result, the running speed rises unconsciously, and the exercise intensity tends to be excessively large with respect to the target value. Therefore, even if you know your own appropriate exercise intensity, even if you run at a running speed and a running pitch corresponding to the target exercise intensity, it is difficult to exercise at that intensity if you go down the slope, There was also a problem that it was not possible to exercise properly.

As described above, in the prior art, firstly, since there is no exercise index in consideration of the physical and mental physical strength of the subject, training with an appropriate intensity and allocation of pace in various competitions are not performed. The problem of not being able to obtain objective information when making a decision,
However, even if an appropriate strength is required, when exercising freely without using exercise equipment such as a treadmill or a bicycle ergometer, at the desired strength, There was a problem that it was difficult to exercise. The present invention has been made in view of the above-described problems, and an object of the present invention is to exercise strength in consideration of the physical and mental physical strength of a subject comprehensively, and to increase the whole body endurance. It is an object of the present invention to provide an exercise index measurement method and apparatus capable of notifying an exercise index indicating the intensity of training necessary for exercise regardless of the type of exercise and the place of exercise.

[0008]

In order to achieve the above object, according to the present invention, a step of determining a point at which a subject's beat rate and exercise pitch are synchronized with each other within a predetermined range is determined. And determining the exercise intensity corresponding to the point according to the altitude difference of the subject.

Before describing the embodiments of the present invention, the principle on which the present invention is based will be described.
First, the present inventors conducted an experiment in which the running speed of the subject was changed stepwise to collect various data in order to use the index as an index of exercise intensity in ergometry.
The results of this experiment will be described with reference to FIG. FIG. 1A shows, on the same diagram, firstly the relationship between the running speed and the number of beats in the ground running, and secondly, the relationship between the running speed and the running pitch in the ground running. . As shown in this figure, it can be seen that the number of beats and the running pitch of the subject increase with the running speed. FIG. 2B is a diagram showing the relationship between the running speed and the subject's subjective exercise intensity in ground running. Here, the subjective exercise intensity is obtained by scoring what subjective sensation accompanies when the subject runs at that speed,
As shown in FIG. 4, the height is set so that the user feels "tight". As shown in FIG. 3 (b), as the running speed increases, the score indicating the subjective exercise intensity also increases, the degree of "tightness" felt by the subject increases, and it can be seen that the mental margin is lost. Next, FIG.
It is a figure which shows the relationship between the running speed in ground running, and the blood lactate concentration calculated | required by the earlobe blood sampling method. As shown in this figure, it can be seen that near the point A, the blood lactate concentration of the subject starts to rise sharply.

[0010] As is well known, lactic acid is a fatigue substance. Therefore, when its concentration is increased, exercise cannot be continued at a constant intensity. Conversely, if simply performing a sustained exercise, the exercise may be performed at an intensity in a region where the lactic acid concentration is low. On the other hand, even if the exercise intensity is such that the lactic acid concentration is suppressed to a low level, the effect of the training cannot be expected if the exercise intensity is such that the subject feels “easy”. Therefore, if continuous exercise is performed in order to increase the endurance of the whole body, the exercise intensity should be in the region where the blood lactate concentration of the subject is low, and the exercise intensity that the subject feels "somewhat hard". It is considered preferable. Such exercise intensity corresponds to point A in the figure. In fact, when the exercise intensity corresponding to the point A at which the blood lactate concentration starts to increase is shown as a relative intensity using the maximum oxygen uptake, almost 50% VO2 ma
x / wt, and it is also known that this value is appropriate as the exercise intensity of the training performed to increase the endurance of the whole body. Therefore, the exercise intensity corresponding to the point A is an exercise intensity in consideration of the physical and mental state of the subject at the time of exercise, and is an exercise intensity to be used as an index when performing training for enhancing the whole body endurance. It can be said.

However, in order to directly determine the point A, it is necessary to continuously measure the blood lactate concentration during exercise. This is extremely difficult in practice.

Here, the present inventors have paid attention to the fact that the pulse rate and the pitch of the subject are synchronized with each other near the rising point A of the lactic acid concentration, that is, they are substantially the same. As described in the related art, if the number of beats and the running pitch during exercise are used, it is possible to quantitatively indicate the physical exercise intensity with respect to exercise intensity. Therefore, by determining a point where the number of beats of the subject and the pitch are synchronized and determining the exercise intensity at that point, it is possible to indirectly determine the exercise intensity corresponding to the point A. By notifying the exercise intensity, an appropriate index for performing training for increasing the endurance of the whole body is provided. Also, at this time, by providing a means for detecting the altitude difference, and by providing an index in consideration of the result, it is not necessary to limit the exercise to a place such as a flat road, a course or a general road that is normally used, This can be done in a park or the like. further,
The exercise intensity of the subject can easily reach the exercise intensity necessary for enhancing the endurance of the whole body by notifying the exercise instruction of the direction that eliminates the difference between the number of beats and the pitch of the subject.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

<1: First Embodiment> First, the first embodiment of the present invention
A motion index measurement device according to an embodiment will be described.
The exercise index measuring device according to the present embodiment, in accordance with the above principle, considers exercise intensity at which the subject's pulse rate and exercise pitch are substantially the same, and comprehensively considers the physical and mental physical strength of the subject during exercise. It is an intensity, and is notified as an exercise index indicating the intensity of training necessary for enhancing the endurance of the whole body. In the present embodiment,
For the purpose of explanation, the exercise form performed by the subject is assumed to be running (running) in a broad sense including walking in daily life and climbing walking, but the present invention is not limited to this.

<1-1: Functional Configuration> First, the functional configuration of the exercise index device according to the present embodiment will be described. FIG.
FIG. 2 is a block diagram showing the functional configuration. In this figure, a pulse wave detection unit 101 is a sensor that detects a pulse wave waveform of a subject. The pulse wave waveform signal from the pulse wave detection unit 101 is converted into a digital signal by the A / D conversion unit 102, and is further subjected to FFT (fast Fourier transform) processing by the FFT processing unit 103. Desired. Although what is originally required is the heart rate, that is, the heart rate per unit time, since the heart rate is equal to the pulse rate, the obtained pulse rate is obtained indirectly as the heart rate. Therefore, the pulse wave detector 101
As for, the configuration may be such that the electrocardiogram is directly detected.

On the other hand, the body movement detecting section 111 is a sensor for detecting the movement of the body in the movement of the subject, and includes, for example, an acceleration sensor. This body movement detection unit 111
Is converted into a digital signal by the A / D converter 112 in the same manner as the pulse wave waveform signal.
The FFT processing is performed by the FT processing unit 113, and the motion pitch is obtained based on the processing result. That is, the exercise in the present invention refers to a repetitive exercise having a rhythmic property performed at a constant cycle, and it is required how many times the repetitive exercise is performed per unit time. Here, since the exercise mode is running, the number of steps per unit time (running pitch) is obtained. In the case of swimming exercise, for example, the number of strokes per unit time is obtained.

On the other hand, the altitude detecting section 171 is a sensor for measuring the altitude in the movement of the subject, and is composed of, for example, a diaphragm whose resistance changes due to pressure distortion. In the altitude detection unit 171, the altitude signal represented by the voltage applied to the resistor is converted into a digital signal by the A / D conversion unit 172, similarly to the pulse waveform signal. The altitude difference information calculation unit 173 temporarily stores the altitude signal converted into the digital signal, and subtracts the altitude indicated by the past altitude signal already temporarily stored from the altitude indicated by the altitude signal at the present time, to thereby store the altitude signal. The height difference of the subject during the period is determined for a predetermined time (for example, 30
Every second) and output it.

The second storage unit 131 stores the weight of the subject, the amount of movement during one repetitive exercise, and the like. Here, since the exercise mode is running, a reference stride (reference stride) is stored. In addition,
For example, in the case of swimming exercise, the distance in one stroke is stored.

Next, the first table 1351 stores in advance the relationship between the ratio of the running pitch to the reference pitch and a first correction coefficient for multiplying the reference stride, and outputs the latter corresponding to the former. It is. On the other hand, the second table 1352 stores the relationship between the altitude difference and the second correction coefficient for multiplying the reference stride in advance, and outputs the latter corresponding to the former. The correction unit 136
Is for multiplying the reference stride stored in the second storage unit 131 by the first and second correction coefficients output from each table to output a corrected (corrected) stride.

Here, the first table 1351 and the second table 1351
The purpose of providing the table 1352 will be described. In the present embodiment, several scenes for obtaining the traveling speed appear. Here, the traveling speed is generally obtained by the product of the traveling pitch and the stride. Of these, the running pitch can be accurately obtained by performing the FFT processing on the body motion signal, but the stride varies depending on the running pitch and gradient in the running motion. Therefore, it is necessary to correct the reference stride stored in the second storage unit 131 according to these factors. Therefore, in the present embodiment, a concept of a reference pitch indicating a pitch when traveling on a flat road with the reference stride stored in the second storage unit 131 is provided. When the stride is corrected in accordance with the actual running pitch, first, a ratio of the running pitch to the reference pitch is obtained, and second, a first correction coefficient corresponding to the ratio is set to the first correction coefficient. Thirdly, the data is read from the table 1351, and the third correction coefficient is multiplied by a reference stride for correction. When the stride is corrected in accordance with the gradient, first, a second correction coefficient corresponding to the altitude difference is read from the second table 1352, and second, the second correction coefficient is used as a reference stride. It was decided to multiply and correct. Therefore, the correction unit 136
By multiplying the reference stride stored in the second storage unit 131 by the first and second correction coefficients output from each table, a corrected stride corrected according to the running pitch and the gradient is output. Becomes Note that such a first table 1351 and a second table 1352 are actually stored in a RAM, which will be described later, based on input values based on actual measurement.
The method of creating these will be described later.

The third storage unit 121 stores the set of the determined number of beats, the running pitch, and the corrected stride, together with the elapsed time and the altitude difference between them.
The determination unit 122 determines, from the contents of the third storage unit 121, a point where the number of beats and the exercise pitch are synchronized with each other, and outputs a running pitch corresponding to the point as a target value. In consideration of a measurement error, it is not necessary to set a perfect synchronization point.
, The two may be regarded as synchronized. In addition, the determination unit 122 in FIG. 1 determines that the point where the beat count and the running pitch are synchronized with each other is determined from the storage content of the third storage unit 121, but the present invention is not limited to this. A configuration for detecting a synchronization point may be adopted. Further, the determination unit 122 outputs the running pitch corresponding to the point where the beat count and the exercise pitch are synchronized with each other, but the determination unit 122 may output the beat count, or may output both.

Next, the switch 132 is used to select one of the travel pitch (input terminal a) set as the target value by the determination unit 122 and the current motion pitch (input terminal b) obtained by the FFT processing unit 113. Is selected, and the selection is instructed by the control unit 160. The exercise intensity calculator 133 calculates the exercise intensity from the running pitch, the corrected stride, the altitude difference, and the weight. Therefore, if the input terminal a is selected by the switch 132, the target exercise intensity is obtained, while if the input terminal b is selected, the exercise intensity when the subject is actually exercising is obtained. It has become. Here, in the case where the exercise mode performed by the subject is running, the running speed is obtained by multiplying the running pitch of the subject and the stride, and the exercise intensity on a flat road is obtained from the running speed and the weight of the subject. be able to. If a gradient is involved, the product of the height difference and the weight (ie, the potential energy of the subject) is adjusted with respect to the exercise intensity obtained from the running speed and the weight of the subject.

The exercise intensity may be expressed using the number of beats. Therefore, the exercise intensity computing unit 133 inputs the number of beats obtained by the FFT processing unit 103 instead of the running pitch, and inputs the exercise intensity. May be performed. If the exercise is running, as the exercise intensity, the running speed, which is the product of the running pitch and the stride, the product of the running speed and the beat, the product of the pitch and the beat, the product of the stride and the beat, For example, the exercise intensity calculation unit 133 may be configured to calculate them.

Next, the first storage unit 134 stores the exercise intensity obtained by the exercise intensity calculation unit 133 when the input terminal a is selected, that is, the target exercise intensity.
It is stored together with the data indicating the obtained date.

When a fourth function described later is executed, the comparing section 141 calculates a difference between the number of beats calculated by the FFT 103 and the exercise pitch calculated by the FFT processing section 113, and further calculates the difference. However, the occupancy of the beat or the pitch is determined, and grading is performed in accordance with the degree. In addition, comparison section 1
Reference numeral 41 denotes an FF when a fifth function described later is executed.
Number of beats obtained by T103 and FFT processing unit 113
The exercise pitch is calculated by comparing the exercise pitch obtained by the above with the exercise pitch to eliminate the difference between the two. Here, if the difference between the two is zero, that is, if the two are in agreement and synchronized, it means that the subject has a sustainable exercise intensity at this time, and exercises at the target exercise intensity. Means that Therefore, the degree obtained by the comparing unit 141 in the fourth function is
It is an index indicating how much the exercise intensity at the present time is different from the target exercise intensity, and the exercise instruction required in the fifth function is an index for approaching the target exercise intensity. Becomes

The notifying unit 151 stores the contents of the first storage unit 134, the contents of the third storage unit 121, and the exercise intensity calculation unit 1.
The following notification is mainly performed based on the calculation result by the calculation unit 33 and the comparison result / index by the comparison unit 141. That is, the notifying unit 151 notifies the first function of displaying the set of the determined number of beats and the exercise pitch in association with the ups and downs of the travel route and the elapsed time after the start of the travel, and the target exercise intensity. The second function to display, the third function to display the exercise intensity currently performed by the subject, and the notification and display of how much the exercise intensity at the current time differs from the target exercise intensity. A fourth function, a fifth function of notifying an instruction for approaching the target exercise intensity with respect to the exercise intensity at the current time, and a second function.
Display how the exercise intensity obtained by the function of the user progresses with the passage of time at the monthly level.
Function. The control unit 160 controls the operation of each unit.

<1-2: Electrical Configuration> Next, an electrical configuration for realizing the functional configuration shown in FIG. 1 will be described. FIG. 2 is a block diagram showing the configuration. In this figure, a CPU 201 performs control of each unit via a bus B, execution of various processes, calculations, and the like based on a basic program stored in a ROM 202. The FFT processing units 103 and 113 in FIG. , Determination unit 12
2, exercise intensity calculation unit 133, correction unit 136, comparison unit 14
1, and corresponds to the control unit 160 and the altitude difference information calculation unit 173. The RAM 203 stores the set of the determined number of beats and exercise pitch in association with the altitude difference and the elapsed time after the start of running, and stores various data used in the control by the CPU 201, such as the weight of the subject and the reference stride. And the like, and various tables, and correspond to the first storage unit 134, the second storage unit 131, the third storage unit 121, the first table 1351, and the second table 1352 in FIG.

Now, the sensor interface 204
The analog output signals from the pulse wave detecting unit 101, the body motion detecting unit 111, and the altitude detecting unit 171 are sampled at predetermined intervals, converted into digital signals, and output. D conversion unit 10
2, 112, and 172.

On the other hand, the clock circuit 205 has a function of transmitting an interrupt signal to the CPU 201 at predetermined time intervals and performing various types of interrupt processing, in addition to a normal clocking function. The operation unit 206 selects an input of a subject's weight, a reference stride, and the like, and selects various functions (modes).
The setting is performed by various button switches as described later. The display unit 207 includes the CPU 2
01 displays various kinds of information under the control of the control unit 01, and is constituted by, for example, an LCD (liquid crystal display panel).
The alarm unit 208 generates an alarm sound under the control of the CPU 201 to notify the subject of various state changes. The display unit 207 and the alarm unit 208
Correspond to the notification unit 151 in FIG. Also,
The I / O interface 209 has an LED and a phototransistor, which will be described later, and exchanges information with an external device.

Here, a method of creating the first table 1351 showing the correspondence between the ratio to the reference pitch and the first correction coefficient will be described. Since this relationship is considered to vary greatly from subject to subject, it is necessary to edit a general relationship prepared in advance in accordance with the characteristics of the subject himself / herself obtained by actual measurement. First, when examining a general relationship, it is considered that the stride becomes shorter as the pitch increases, so that the relationship prepared in advance has a large ratio with respect to the reference pitch as shown by the solid line in FIG. It is only necessary that the first correction coefficient to be multiplied by the reference stride be gradually smaller. Next, it is necessary to edit the relationship shown by the solid line according to the characteristics of the subject, and as shown by the broken line in the figure, according to the characteristics of the subject. This editing is performed, for example, by the following method. Is possible. That is, first,
The subject runs while increasing the pitch in steps of, for example, 10% with respect to the reference pitch, and measures the actual stride at each step to determine how much the stride is compared to the reference stride. Ask for it. Secondly, the subject plots the ratio with respect to the reference pitch and the ratio with respect to the reference stride, and interpolates between the plots to finally obtain the characteristic as shown by the dashed line in FIG. The calculation, plotting, and interpolation of the ratio are performed by the CPU.
201, and the storage of the obtained characteristics can be assigned to the RAM 203. Therefore, what the user actually needs is a pitch increase rate and a stride when the pitch is increased stepwise. It is only necessary to input the actual measurement value of

The method of creating the second table 1352 indicating the correspondence between the altitude difference and the second correction coefficient is basically the same as the method of creating the first table 1351. Since this relationship is also considered to differ greatly from subject to subject, it is necessary to edit a general relationship prepared in advance in accordance with the characteristics of the subject himself / herself obtained by actual measurement. First, when examining the general relationship, the altitude difference increases in the positive direction, and the stride becomes shorter as the degree of the ascending gradient becomes steeper, while the altitude difference increases in the negative direction, and the descending gradient increases. Since it is considered that the stride becomes longer as the degree becomes tighter, the general relationship prepared in advance may be any as shown by the solid line in FIG. Next, it is necessary to edit the relationship shown by the solid line according to the characteristics of the subject, and as shown by the broken line in the figure, according to the characteristics of the subject itself.
For example, the following method is possible. That is, first, the subject runs at the reference pitch at a plurality of points where the magnitude of the gradient is known, measures the actual stride at each point, and determines the ratio of the actual stride to the reference stride. Ask for it. Second, the subject plots the height difference between these gradients and the ratio to the reference stride, and interpolates between the plots to finally obtain the characteristics shown by the dashed lines in FIG. Of these, the calculation, plotting, and interpolation of the ratio can be borne by the CPU 201, and the storage of the obtained characteristics can be borne by the RAM 203. It is only necessary to input the altitude difference and the actual measured value of the stride through the operation unit 206.

While having the LED 604 for transmitting an optical signal, the reception control unit has a phototransistor 605 for receiving an optical signal. The LED 604 and the phototransistor 605 have a device main body 5 of the motion index measuring device.
LED 507, phototransistor 508 at 00
The characteristics which are the same as or approximate to the characteristics are used. Here, a near infrared type (for example, one having a center wavelength of 940 nm) is desirable. When a near-infrared type is used, a visible light cutoff filter for blocking visible light is provided on the front surface of the device main body 600, and serves as a communication window 606 for optical communication. Such an external device and the device main body 500 of the exercise index measurement device are:
Information transmission and reception are performed mutually by optical communication. The contents of the information exchange will be described in the operation.

<1-5: Operation> Next, the operation of the exercise index measuring apparatus according to the present embodiment will be described. As described above, since the apparatus main body 500 has various functions, the operation will be described for each of these functions.

<1-5-1: First Function> First, a first function (that is, a function of displaying the set of the determined number of beats and the running pitch in association with the ups and downs of the running route and the elapsed time) The operation in the case of executing is described.
When the subject operates the button switch 513 to set the mode for executing the first function, C in FIG.
After executing the basic process shown in FIG. 7, the PU 201 (the control unit 160 in FIG. 1) periodically executes the interrupt process shown in FIG.

First, the processing contents of the basic processing are shown in FIG.
This will be described with reference to FIG. In step Sa1, the CPU 2
01, the body motion signal detected by the body motion detection unit 111 is input via the sensor interface 204, and is subjected to FFT processing to determine whether or not the subject has actually started running. I do. If the CPU 201 determines that exercise has not been started, the CPU 201 returns the processing procedure to step Sa1 again. That is, the processing procedure waits in step Sa1 until the subject starts running. Actually, when the subject starts running, the CPU 201 clears the value of the register n to zero in step Sa2, permits execution of the interrupt processing in step Sa3, and ends the basic processing. Here, the interrupt process is a process that is periodically executed, for example, every minute by an interrupt signal from the clock circuit 205. As described above, in the basic processing, the mode is set to execute the first function, and the periodic execution of the interrupt processing is permitted after the subject actually starts running. ing.

Next, the contents of the interrupt processing will be described with reference to FIG.
This will be described with reference to FIG. First, in step Sa11, the CPU 201 increments the register n by “1”. Since the register n has been cleared to zero in step Sa2 described above, the content indicates how many times the interrupt process has been executed after the subject started exercising. This interrupt processing is executed at regular intervals. Therefore, the register n indirectly indicates the elapsed time after the start of the exercise. Needless to say, the elapsed time after the start of the exercise is obtained by multiplying the value set in the register n by the interval of the interrupt processing.

In step Sa12, the CPU 2
In step 02, the pulse wave waveform signal detected by the pulse wave detection unit 101 is read via the sensor interface 204, and then subjected to FFT processing to obtain the pulse rate of the subject, that is, the pulse rate [beat / minute]. Subsequently, in step Sa13, the CPU 201 reads the body motion signal detected by the body motion detection unit 111 via the sensor interface 204, and then performs FFT processing to obtain a running pitch [times / minute] of the subject. Here, when the subject exercises, a spectrum associated with the regularity of the exercise is detected, and the exercise pitch (in this case, the running pitch) is obtained by specifying the frequency of the spectrum.

Next, at step Sa101, the CPU
First, after reading the altitude signal detected by the altitude difference detection unit 171 through the sensor interface 204, the RAM 201 temporarily stores the altitude signal in the RAM 203,
Then, the altitude indicated by the altitude signal temporarily stored previously is subtracted from the altitude indicated by the altitude signal to obtain the altitude difference of the subject. Needless to say, the time required for this altitude difference is the execution interval of the interrupt processing. further,
In step Sa14 ', the CPU 201 stores the obtained number of beats, the running pitch, and the altitude difference as a pair in the RAM 203 in association with the current value of the register n. For this reason, the detected number of beats, running pitch and altitude difference are sequentially accumulated and stored in the RAM 203 every time the interrupt processing is executed.

Next, at step Sa15 ', the CPU
201 reads out the stored beat count, running pitch, and altitude difference from the RAM 203, and in step Sa16 ', displays the read beat count and running pitch on the y-axis on the display unit 207 and the value of the corresponding register n. Is plotted on the x-axis, and a two-dimensional display is performed. On the other hand, a display indicating the undulation of the terrain on which the subject has traveled is also performed in accordance with the register n based on the read altitude difference. In such a display, it should be noted that the running pitch and the number of beats are absolute values, but the altitude difference is a relative value. FIG. 15 shows an example of this display. As described above, since the value of the register n indicates the elapsed time after the start of the exercise, such a display indicates how the pulse rate and the running pitch have changed after the start of the exercise, and further indicates the change. Display section 2 shows the relationship between the ups and downs of the travel route.
07. Therefore, the subject can know how his / her own pulse rate and running pitch are changing in relation to the undulation of the running route. However,
If the form of the exercise index measuring device is a wristwatch type as shown in FIG. 5, the display capability of the display unit 207 is necessarily limited.
For this reason, as described later, it is preferable to transmit the read information to an external device and analyze the information there.
When the display process of step Sa15 'is executed, the CPU 2
In step 01, the current interrupt processing ends in preparation for the next execution.

By executing such basic processing and interrupt processing, the first function executed by the functional configuration shown in FIG. 1, that is, the number of beats and the running pitch stored in the third storage unit 121 is determined. The function of displaying the undulation of the travel route in association with the elapsed time after the start of the exercise is equivalently executed by the internal configuration in FIG.

<1-5-2: Second Function> Next, a second function (that is, a function for displaying a target exercise intensity).
The operation in the case of executing is described. When the subject operates the button switch 513 to set a mode for executing the second function, the CPU 201 in FIG.
Executes the basic processing shown in FIG.
The interrupt processing shown in FIG.

First, the processing contents of the basic processing are shown in FIG.
This will be described with reference to FIG. This basic processing is for setting information that is prerequisite for displaying the target exercise intensity and for permitting the interrupt processing, and specifically includes the following steps Sb1 to Sb9.

First, the CPU 201 determines in step Sb1
, An initial setting process such as securing a necessary area in the RAM 203 or clearing the area is executed. Next, in step Sb2, the CPU 201 determines whether or not information such as the amount of movement of the subject in one repetitive exercise and the weight of the subject is set in the RAM 203. Since the exercise in the present embodiment is a running exercise, the CPU 201 determines whether or not information on the reference stride (reference stride) and the weight of the subject is set. In the present embodiment, when the second function is executed for the first time, since no information is set in the RAM 203, the determination in step Sb2 is performed.

When the above information is set, the CPU
201 sets the set value to RA in step Sb3.
At the next step Sb4, a message prompting the subject to select whether or not to change these values is displayed. When the subject gives an instruction not to change, the CPU 2
In step Sb5, the information is reset in the RAM 203 as a default value.

On the other hand, if the information has not been set in the RAM 203, or if an instruction to change the information has been given, the CPU 201 determines in step Sb6 whether or not the information has been input. Is not input, the process returns to step Sb6. That is, the processing procedure waits in step Sb6 until the reference stride or the weight of the subject is input. When the information is input or changed, the CPU 201 sets those values in the RAM 203 in step Sb7.

Here, as an instruction to change the information such as the reference stride, for example, it is considered that the subject operates the button switch 513 to set the operation mode of the apparatus main body 500 to the input / change mode. It is. As an instruction not to change, the subject may not operate the button switch 513 for a certain period of time. Further, as a method of changing / inputting information such as the reference stride, for example, the subject sets the input / change mode and further sets the target to be changed / input by the button switch 514 to either the reference stride or the weight. After that, it is conceivable to raise or lower the target value by one using the button switch 511 or 512.

When the reference stride of the subject and information on the weight are set in the RAM 203, in step Sb8, the CPU 201 determines whether the subject has actually started exercising in the same manner as step Sa1 in the basic processing. Is determined, and if it is determined that the exercise has not been started, the process returns to step Sb8. That is, the processing procedure waits in step Sb8 until the subject starts exercising. When the subject actually starts exercising, the CPU 201 proceeds to step Sb
At 9, the execution of the basic processing is terminated after the execution of the interruption processing is permitted. Here, the interrupt process is a process that is periodically executed, for example, every two minutes by an interrupt signal from the clock circuit 205. As described above, when the basic processing is executed, information necessary for calculating the exercise intensity is set, and the mode is set to execute the second function. The periodic execution of the incorporation process is permitted.

Next, the contents of the interrupt processing will be described with reference to FIG.
0 will be described. First, in step Sb11, the CPU 201 obtains the number of beats [beats / minute] of the subject,
Next, in step Sb12, the running pitch [times / minute] of the subject is determined, and subsequently, in step Sb131, the height of the subject is detected, stored, and the height difference is determined. This is the same as steps Sa12, Sa13, and 101 in the interrupt processing. Subsequently, in step Sb132, the CPU 201 determines whether or not the subject has traveled on a flat road, based on whether or not the altitude difference obtained in the immediately preceding step is zero.
Here, since the obtained altitude difference involves some error, it may be determined whether or not the altitude difference is within a predetermined value.

Here, if there is an altitude difference, the CPU 201
Executes the following processing in step Sb133.
That is, the CPU 201 first obtains the ratio of the obtained running pitch to the reference pitch, reads the first correction coefficient corresponding to the ratio with reference to the first table 1351 stored in the RAM 203, The second correction coefficient corresponding to the obtained altitude difference is read out with reference to the table 1352, and secondly, the reference stride stored in the second storage unit 131 is multiplied by both the first and second correction coefficients. Third, a stride corrected in accordance with the traveling pitch and the altitude difference is obtained, and thirdly, a traveling speed is obtained by multiplying the obtained stride by the obtained traveling pitch. On the other hand, if there is no altitude difference, the CPU 201 proceeds to step Sb
At 134, the following processing is executed. That is, CPU
201, first, calculates the ratio of the obtained running pitch to the reference pitch, refers to the first table 1351 stored in the RAM 203, reads out the first correction coefficient corresponding to the ratio, and secondly, 2 multiplies the reference stride stored in the storage unit 131 by only the first correction coefficient to obtain a corrected stride according to the traveling pitch.
The running speed is obtained by multiplying this stride by the obtained running pitch. Then, the CPU 201 determines in step Sb1
In step 4, the detected number of beats and the running pitch are stored in the RAM 203 in association with the running speed.

The second function is to display the exercise intensity at the point where the beat rate and the running pitch are synchronized with each other as a target value. At this time, the beat rate and the running pitch have different running speeds. If two or more points are not determined in, the point to be synchronized cannot be determined. For this reason, the CPU 201
Executes the processing of the following steps Sb16 to Sb22 on condition that at least two sets of the number of beats and the running pitch are stored in step Sb15, and that their running speeds are not the same value.

That is, if the decision result in the step Sb15 is "Yes", the CPU 201 proceeds to the step Sb1.
6, first, all the beats and the running pitch stored in the RAM 203 are read, and second, a regression line of the beat corresponding to the running speed is obtained. A regression line is obtained, and thirdly, an intersection between the regression line of the pulse rate and the regression line of the traveling speed is determined, and a point where the pulse rate and the traveling pitch are synchronized is determined. In consideration of the measurement error, it is not always necessary to use the intersection, and the difference between the number of beats and the running pitch is ± 10% in detecting the synchronization point.
, The two may be regarded as synchronized. Further, a configuration in which the range in which the difference between the number of beats and the running pitch is considered to be synchronized may be set by, for example, a button switch or an external device described later.

Next, the CPU 201 obtains a running pitch corresponding to the obtained intersection (step Sb17), and controls the alarm unit 208 to generate an alarm sound corresponding to the running pitch as a motion index (step Sb1).
8). For example, as the alarm sound, a sound corresponding to the frequency of the traveling pitch, such as “beep, beep, beep”, can be considered. Further, in this case, the display is not limited to the display, and a configuration in which the notification is made in various modes such as voice synthesis and the intensity of an alarm sound may be considered. Further, the CPU 201 obtains a running speed corresponding to the obtained intersection (step Sb19), and calculates an exercise intensity corresponding to the running speed (step Sb).
20). This calculation is performed, for example, by using RAM2
03 may be multiplied by the weight of the subject stored, or may be calculated from the relationship between the running speed and the exercise intensity. In this state, since the altitude difference is not considered, the product of the obtained altitude difference and the weight of the subject stored in the second storage unit 131 is calculated with respect to the obtained exercise intensity.
The addition may be performed including the sign. This allows
In the case of an ascending gradient, the potential energy of the subject is added, while in the case of a descending gradient, the potential energy of the subject is subtracted, so that the exercise intensity can be more accurately obtained. Then, the CPU 201 calculates the obtained exercise intensity
The date of the running exercise is stored in the RAM 203 (step Sb21), and the obtained exercise intensity is displayed on the display unit 207 as a target exercise index (step Sb22).

The exercise intensity obtained in this manner is a value at a point where the beat rate and the running pitch are synchronized, and should be used as an index when performing an exercise for enhancing the endurance of the whole body. . Here, if the exercise intensity is obtained from the physical exercise intensity of the subject as in step Sb20, the absolute intensity in the running exercise can be obtained.
This is convenient for performing various comparisons. However, for the test subject, it is easier to intuitively understand the target exercise intensity when the running pitch (or the number of beats) is indicated by the alarm unit 208 when exercising. That is,
From the viewpoint of the subject, the target exercise can be achieved if the exercise is performed in accordance with the indices indicated in a sensory manner, which is more convenient. Therefore, in the interrupt processing, the running pitch is notified as the motion index in step Sb17 described above, and step Sb22 is executed.
In this example, the strength of physical exercise is displayed.

The exercise index may be the number of beats.
A configuration may be adopted in which these are selected to notify and display one of them. When both the pulse rate and the running pitch are notified as the exercise index, the subject controls the running speed by setting the pulse rate notified as the exercise index as a priority target and increasing or decreasing the intensity of the running exercise. And a method of controlling the number of beats as a result of self-control with the traveling speed notified as a motion index as a priority target. Further, if the exercise mode is running as in the present embodiment, as the exercise intensity, a running speed that is a product of the running pitch and the stride, a product of the running speed and the number of beats,
A product of the pitch and the beat rate and a product of the stride and the beat rate can be used, and these may be notified and displayed as a motion index. Since such a motion index is an index for performing efficient running, the subject may run using this as a target value.

After the processing in step Sb22, or if the determination result in step Sb15 is "No", the CPU 201 ends the current interrupt processing in preparation for the next execution. Note that this interrupt processing is executed at regular intervals, and the number of beats and pitch stored in the RAM 203 increase each time. Therefore, if the traveling speed is divided into at least two stages, the opportunity of the determination result “Yes” of step Sb15 comes, and the motion index is notified,
Will be displayed.

With the execution of the basic processing and the interrupt processing, the second function executed by the functional configuration in which the switch 132 selects the input terminal a in FIG. Is equivalently executed by the internal configuration shown in FIG.

<1-5-3: Third Function> Next, the operation in the case of executing the third function (ie, the function of displaying the intensity of the exercise actually performed by the subject) will be described. When the subject operates the button switch 513, the third
When the mode is set to execute the function of FIG. 11, the CPU 201 in FIG.
The interruption processing shown in (1) is periodically executed. The basic processing in this case has the same contents as the basic processing shown in FIG. That is, the basic processing sets the information necessary for the exercise intensity calculation, sets the mode for executing the third function, and periodically starts the interrupt processing when the subject actually starts the exercise. This is a process that permits execution.

Therefore, the description of the basic processing will be omitted, and the processing content of the interrupt processing will be described with reference to FIG.
First, in step Sc11, the CPU 201 obtains the number of beats [beat / minute] of the subject, and then, in step Sc12.
In step Sc131, the running pitch [times / minute] of the subject is determined. Subsequently, in step Sc131, the height of the subject is detected and stored.
At c132, it is determined whether there is an altitude difference. If there is an altitude difference, the CPU 201 determines in step Sc133 that the first table 1351 and the second table 13
Using both 52, the reference stride is corrected in accordance with the running pitch and the altitude difference, and the running speed is obtained by multiplying the obtained running pitch. On the other hand, if there is no altitude difference, the CPU 20
1 corresponds to the first table 13 in step Sc134.
Using 51, the reference stride is corrected according to only the running pitch, and the running speed is obtained by multiplying the obtained running pitch. The processing in steps Sc11, Sc12, 131 to 134 described above is performed in step Sb1 in the above-described interrupt processing.
1, 12, 131 to 134.

Subsequently, the CPU 201 proceeds to step S
In c14, the exercise intensity corresponding to the running speed obtained in the immediately preceding step is calculated and obtained. This calculation is the same as in step Sb20. Then, the CPU 201
In step Sb21, the determined exercise intensity is displayed on the display unit 2.
07 is displayed. The exercise intensity displayed in this manner is obtained at the execution timing of the interruption processing for the running exercise actually performed by the subject, taking into account the running pitch and the altitude difference. In addition, the sampling interval of the exercise intensity obtained by the third function is
This is the execution interval of the interrupt processing.

By executing the basic processing and the interrupt processing as described above, the third function executed by the functional configuration in which the switch 132 selects the input terminal b in FIG. The function of displaying the intensity of the present exercise is equivalently executed by the internal configuration shown in FIG.

<1-5-4: Fourth Function> Next, the fourth function (that is, the intensity of the exercise performed by the subject is
The operation in the case of executing the function of displaying how much the exercise intensity differs from the target exercise intensity) will be described.
When the subject operates the button switch 513 to set the mode for executing the fourth function, C in FIG.
After executing the basic processing shown in FIG.
The interruption process shown in FIG. 13 is periodically executed. The basic processing is the same as the basic processing shown in FIG. 7 except that step Sa2 is omitted. That is, the basic processing in the case of executing the fourth function is a processing for setting a mode for executing the function, and permitting the periodic execution of the interrupt processing when the subject actually starts running. It is.

Next, the contents of the interrupt processing will be described with reference to FIG.
3 will be described. First, in step Sd11, the CPU 201 obtains the number of beats [beat / minute] of the subject,
Subsequently, in step Sd12, a running pitch [times / minute] of the subject is obtained. This is the same as steps Sa12 and Sa13 in the interrupt processing. In the following step Sd13, the CPU 201 calculates the degree G from the obtained number of beats and the running pitch by the following equation. Degree G = (beats-running pitch) / running pitch

Then, in step Sd14, the CPU
After causing the display unit 207 to perform display according to the value of the degree G, the 201 ends the current interrupt processing in preparation for the next execution. The degree G obtained here indicates the ratio of the difference between the number of beats and the running pitch to the running pitch, and the closer the value is to zero, the more the exercise intensity at that time increases the endurance. Indicates that the intensity is appropriate for training. If the sign of the degree G is minus, it indicates that the exercise intensity at that time is low for performing the training, while if the sign of the degree G is plus, the exercise intensity at that time is: Indicates that the training is high. Therefore, the display content of the display unit 207 is, for example, as shown in FIG.
It is desirable that the sign of the degree G and the magnitude of the value be intuitively understood. This allows the subject to know whether or not the exercise intensity (running speed) at the current time is appropriate as compared with the intensity at the time of training for increasing endurance. It is also possible to know quantitatively how much the exercise intensity must be increased or decreased to obtain the training intensity. In the display example shown in FIG. 16, the up arrow promotes an increase in strength, the down arrow promotes a decrease in strength, and the number of arrows indicates the degree of increase or decrease. Further, in this case, in addition to the display in various modes other than the illustrated example, not only the visual sense, but also a configuration that performs a notification appealing to other sensations, such as voice synthesis, hearing such as the strength of an alarm sound, and tactile sensation due to vibration, etc. Conceivable.

By performing such basic processing and interrupt processing, the fourth function executed by the functional configuration shown in FIG. 1, that is, how much the exercise intensity at the present time differs from the target exercise intensity. Notify if you are
The function to be displayed is equivalently and periodically executed by the internal configuration in FIG. In addition, this fourth
When the function of is performed in various competitions, it becomes clear how much the exercise intensity at the present time is different from the target exercise intensity (that is, the intensity appropriate for performing the continuous exercise). This will provide you with objective and important information in deciding the pace allocation.

<1-5-5: Fifth Function> Next, a fifth function (that is, a function of giving an instruction to approach the target exercise intensity with respect to the exercise intensity at the current time) is executed. The operation in the case of performing will be described. When the subject operates the button switch 513 to set a mode for executing the fifth function, the CPU 2 in FIG.
No. 01 executes the interrupt processing shown in FIG. 14 periodically after executing the basic processing. The basic processing in this case has the same contents as the basic processing shown in FIG. That is, the basic processing when the fifth function is performed is as follows.
When the mode is set to execute the function and the subject actually starts the running exercise, the interrupting process is periodically executed.

Next, the contents of the interrupt processing will be described with reference to FIG.
This will be described with reference to FIG. First, in step Se11, the CPU 201 calculates the number of beats [beat / minute] of the subject,
Next, in step Se12, the running pitch [times / minute] of the subject is obtained. Subsequently, in step Se101, the height of the subject is detected and stored, and the height difference is obtained. Is determined. If there is an altitude difference, the CPU 201
Is the first table 135 in step Se103.
Using both the first table 1352 and the second table 1352, the reference stride is corrected in accordance with the traveling pitch and the altitude difference, and the traveling speed is determined by multiplying by the determined traveling pitch. On the other hand, if there is no difference in altitude, in step Se104, the CPU 201 uses the first table 1351 to correct the reference stride according to only the traveling pitch, and obtains a traveling speed by multiplying the obtained traveling pitch. The above step Sc11,
The processing of steps 12, 131 to 134 is the same as that of steps Sb11, 12, 131 to 134 in the interrupt processing described above.

Next, the CPU 201 proceeds to step Se10.
In 5, it is determined whether or not the traveling speed obtained in the immediately preceding step is within a certain value (threshold value), or whether the obtained altitude difference is in the positive direction, that is, whether or not the traveling motion is performed on the uphill. to decide. Here, the determination result is “Yes”
In the case of, it is highly probable that the subject is consciously making an effort to bring the intensity of the running exercise at the present time close to the target value. Therefore, if the determination result is “Yes”,
In the next step Se13, the CPU 201 compares the obtained number of beats with the running pitch. And the CPU 20
If the number of beats is smaller than the running pitch, step S
At e14, the display unit 207 is instructed to increase the pitch, and if the number of beats is substantially the same as the pitch, at step Se15, an instruction to maintain the running state is displayed at the display unit 207. On the other hand, if the number of beats is larger than the pitch, in step Se16,
The display unit 20 displays an instruction to reduce the stride (step length).
7 On the other hand, if the result of the determination in step Se105 is “No”, the running motion is on a down slope and is performed at a running speed equal to or higher than a certain value, that is, when the subject unconsciously exceeds the running speed. It is highly probable that proper exercise cannot be performed due to excessive exercise intensity caused by the exercise. Therefore, if the determination result in step Se105 is “No”, the CPU 201 proceeds to step S105.
At e16, the display unit 207 is instructed to reduce the stride, and is notified that the stride is to be reduced or the running speed is to be reduced. Then, after making the notification in any of steps Se14 to Se16, the CPU 201 ends the current interrupt processing in preparation for the next execution.

By the way, the case where the number of beats is smaller than the running pitch means that the running speed is low and the intensity is low for training to increase the endurance of the whole body, as can be seen from FIG. It means that it is too small. For this reason, it is necessary to notify the test subject to increase the exercise intensity, which includes an instruction to increase the amount of exercise per pitch (ie, stride) and an instruction to increase the running pitch. An instruction, an instruction to increase the altitude, and an instruction in which these are arbitrarily combined are possible. Conversely, when the beat rate is greater than the running pitch, as can be seen with reference to the figure, the case where the running speed is high and the intensity is excessive for training to increase the endurance of the whole body. Say. For this reason, it is necessary to notify the subject that the exercise intensity should be reduced, including instructions to reduce the amount of exercise per pitch,
An instruction to reduce the traveling pitch, an instruction to lower the altitude, and an instruction in which these are arbitrarily combined are possible.

In this embodiment, considering the characteristics of general running motion in relation to the fact that the mode of motion is running in a broad sense, if the stride is expanded, the running speed increases, Exercise intensity increases, but muscle fatigue begins to occur, while the number of beats tends to decrease.
When the running pitch is increased, the number of beats tends to increase accordingly. In addition, as can be seen with reference to the figure, the traveling pitch in the region where the traveling speed is high does not change so much as compared with the increase in the traveling speed. This means that in a region where the traveling speed is low, the increase in the traveling speed is mainly performed by increasing the traveling pitch, but in a region where the traveling speed is high, the increase is mainly performed by increasing the stride. Furthermore, the number of beats in the region where the running speed is low,
The fluctuation is intense. Further, in running motion, an appropriate gradient is not always present.

As a result of the above, according to the present embodiment, when the number of beats is smaller than the running pitch, an instruction to increase the running pitch is issued, and the running speed of the subject is reduced without causing muscle fatigue. If the beat rate is greater than the running pitch, the stride should be reduced and the running speed should be reduced while the beat rate should be reduced. Decided to go down. If the number of beats synchronizes with the running pitch, it indicates that the exercise intensity corresponding to the running speed is appropriate as the training intensity for performing the sustained exercise, so that the running state should be maintained. Instructions were given. Also in this case, the beat count and the running pitch do not need to be completely synchronized in consideration of the measurement error. If the difference between them is within a range of ± 10%, for example, it is considered that both are synchronized. Good. Further, in the present invention, the instruction regarding the exercise amount stride per pitch, the exercise pitch, and the altitude difference may be appropriately combined without making the determination as in the present embodiment.

As described above, by executing the basic processing and the interrupt processing, the fifth function executed by the functional configuration shown in FIG. 1, that is, the exercise intensity at the present time is brought closer to the target exercise intensity. The function of notifying the user of the instruction is equivalently and periodically executed by the internal configuration in FIG. For this reason, the subject, in accordance with the instruction content by executing the fifth function,
By performing the running exercise, it is possible to easily reach the target exercise intensity, that is, the optimal intensity when performing the continuous exercise. Note that, in addition to the fifth function, for example, when the exercise intensity at the current time is obtained at the time of execution of the third function, the instruction for bringing the exercise intensity closer to the target exercise intensity is the same as the fifth function. It is also possible to compare with the target exercise intensity obtained by the second function.

<1-5-6: Sixth Function> Next, the sixth function (that is, how the exercise intensity obtained by the second function evolves with the passage of time at the monthly level) Will be described. When the subject operates the button switch 513, the sixth
When the mode is set to execute the function of step Sb2, the CPU 201 in FIG.
2 (see FIG. 10), and secondly, plotting the readout exercise intensity on the y-axis and the corresponding date on the x-axis on the display unit 207 to display two-dimensionally. Is controlled. The exercise intensity displayed here is a value at which the number of beats and the running pitch are synchronized when the running is performed, and is a value that is used as an exercise index. It has a fluctuating property. Therefore,
In this way, when the exercise intensity is displayed in accordance with the date, it is possible to know the training effect of the subject along with time.

In the above description, the first to sixth functions are individually executed. However, after the subject starts exercising, all of the first to sixth functions are performed or May be configured to execute the selected functions. In particular, the fourth and fifth functions are preferably executed at the same time because the processing contents are similar.

<1-5-7: Communication Function> Next, the operation in the case where the exercise index measuring device according to the present embodiment communicates with the external device shown in FIG. 6 to exchange various information will be described. . First, when communicating with an external device, the subject removes the connector piece 504 from the connector section 503 of the device main body 500 to expose the LED 507 and the phototransistor 508, and the communication window 6 of the external device.
06. The following description will be given separately for a transmission function of transmitting information to an external device and a reception function of receiving information from the external device.

<1-5-7-1: Transmission Function> LED 50
7 and the phototransistor 508 are exposed and face the communication window 606 of the external device, the subject operates the button switch 513 to set a mode for executing the transmission function.
The information stored in step Sa14 at the time of executing the first function, that is, the information on the elapsed time after the start of the running exercise and the number of beats and the running pitch associated with the altitude difference, is I / O. The data is transmitted to the device main body 600 via the interface 209 and the optical interface of the external device. Such an optical communication protocol includes Ir
A DA (Infrared Data Association) method or the like can be used.

As described above, by transmitting data from the apparatus main body 500, in the external device, how the subject's pulse rate and running pitch change according to the elapsed time after the start of running and the undulation of the running route. Not only the subject,
The instructor and a third party such as a doctor can objectively know and accumulate and analyze such information.
The information transmitted by the apparatus main body 500 is processed on the external device side, thereby notifying the second function (exercise intensity corresponding to a point at which the number of beats and the exercise pitch are synchronized with each other as a target exercise intensity). Function) need not be processed on the apparatus body 500 side. With such a configuration, it is possible to reduce the load of processing to be performed on the apparatus main body 500 side. Further, in such a configuration,
The condition that the number of beats and the exercise pitch are synchronized with each other may be set on the external device side. Thus, a third party such as a mentor or a doctor can judge the measurement result under the conditions set by himself / herself, and more appropriate information can be obtained than when all functions are integrated in the apparatus main body 500. Can be stored and analyzed. Note that the information to be transmitted is not limited to this, and may be, for example, the information stored in step Sb21. In this case, the sixth function is executed in the external device.

<1-5-7-2: Reception Function> On the other hand, in the external device, a target value in the running motion, for example, a running pitch, is set according to the elapsed time or the undulation of the running route. The exercise index measurement device according to the present embodiment receives a target value set by an external device and uses the target value as a target value when the subject actually starts running. Specifically, the LED 507 and the phototransistor 508
When a subject or the like operates the button switch 513 to set a mode for executing the reception function in a state where the device 201 faces the communication window 606 of the external device, the CPU 201 in FIG. A signal indicating the request is transmitted via the I / O interface 209 and the optical interface of the external device. In response to this, the main body 600 of the external device transmits the information that is the set target value to the optical interface of the external device and the I / O interface.
The data is transmitted via the / O interface 209.

On the other hand, when the information that becomes the target value is received on the apparatus main body 500 side, the CPU 201 converts the received information into R
The target value corresponding to the elapsed time after the start of traveling is read out and notified to the subject when the subject actually starts traveling. At this time, if the target value is the running pitch, the difference between the notified target value and the actual running pitch in the running motion is graded and displayed as in the fourth function. It is good. Thus, the subject can perform the running exercise at the set running pitch even when the exercise is performed for a long period of time, and can be used for training and for creating a pace in a competition or the like. In the present embodiment, the communication function is performed by optical communication. However, in addition to this, various modes such as wireless communication using radio waves and wired communication via a cable can be considered.

As described above, according to the exercise index measuring device of the present embodiment, it is possible to execute the first to sixth functions and the communication function. In particular, by performing the second function, the exercise intensity to be used as an index when performing exercise to increase the endurance of the whole body is considered in consideration of the physical and mental physical strength of the subject during exercise. By performing the fourth function, it is possible to determine how much the exercise intensity at the present time differs from the exercise intensity to be performed to increase the endurance of the whole body.
It can also be obtained quantitatively, and by executing the fifth function, it is possible to give an instruction to bring the exercise intensity at the current time closer to the target exercise intensity. Moreover, in both functions, the variation in stride due to the ups and downs of the travel route and the variation in potential energy due to the difference in altitude are taken into account. It is possible to perform the exercise anywhere outside without using an exercise equipment such as a treadmill. Further, in the exercise index measuring device according to the present embodiment, the exercise index obtained by the second function is defined as a product of a running speed and a beat, a product of a running pitch and a beat, a product of a stride and a beat, and the like. As described above, if the notification is made based on the product of the physical index and the physiological index, the physical index and the physiological index can be comprehensively evaluated. Specifically, even if the same course is completed at the same time, the physiological index changes depending on the physical condition, so the comprehensive evaluation with the physical index is performed. That is, the physical index and the physiological index can be evaluated with one new index.

<1-6: Application and Modification of First Embodiment> The following application and modification of the first embodiment are possible.

<1-6-1: Application and Modification of Configuration> When the subject performs a running exercise, the corrected stride is linked to the current beat and the running pitch, and You may comprise so that it may be memorize | stored in connection with the elapsed time after driving | running | working start and an altitude difference. That is,
The first function may be configured to display the corrected stride in addition to the number of beats, the running pitch, and the undulation of the running route after the start of running. Further, in the transmission function, the corrected stride may also be transmitted to an external device. The function may be configured to receive the information of the set stride and use it as a target value when the subject actually starts running.

In the first embodiment, the reference stride stored in the second storage unit 131 is corrected using two tables, the first table 1351 and the second table 1352. However, the present invention is not limited to this, and the configuration may be such that the correction is performed using one two-dimensional table in which the traveling pitch and the altitude difference are used as arguments (parameters). However, as a practical matter, the combination of the stride conditions to be measured (that is, the combination of the running pitch and the altitude difference) becomes enormous, and the burden on the subject increases.
There are drawbacks. For example, assuming that the running pitch is 5 points and the gradient is 4 points, the stride must be measured for each of the combined 20 points. However, if it is divided into two tables as in the first embodiment, the accuracy may decrease, but the actual measurement of the stride is 5 points when creating the first table 1351, and 4 points when creating the second table 1352. And a total of nine points can be completed, and the burden on the subject can be reduced.

<1-6-2: Another Example of Form> In the above-described embodiment, the form of the movement index measuring device is a wristwatch structure, but the present invention is not limited to this. Then, some examples of the form of the exercise index measuring device according to the present invention will be described.

<1-6-2-1: Necklace Type> For example, the exercise index measuring device according to the present invention may be a necklace as shown in FIG. In this figure, reference numeral 1601 denotes a sensor pad which is formed of a sponge-like cushioning material or the like. In the sensor pad 1061, the pulse wave detection unit 101 is attached so as to contact the skin surface. Therefore, when the necklace is put on the neck, the pulse wave detection unit 101 comes into contact with the skin on the back side of the neck, the pulse wave is measured, and the pulse rate is obtained. Also, in the figure,
The main part of the device is incorporated in a case 1602 having a hollow part similar to a broach, and if necessary, an LED for communication, a photodiode, and a button switch for various settings are provided. , Are provided on the back surface of case 1602 (not shown). Further, the pulse wave detection unit 101 and the case 1602 are attached to a chain 1603, respectively, and are electrically connected via a lead wire (not shown) embedded in the chain 1603.

<1-6-2-2: Glasses Type> On the other hand, as an embodiment other than a wristwatch, a combination with glasses as shown in FIG. 18 can be considered. In this embodiment, the main body of the apparatus is attached to the left vine 1701 in the eyeglass frame,
The main body is further divided into a case 1702a and a case 1702b, and is connected via a lead wire embedded inside the vine 1701. Note that this lead wire may be crawled along the vine 1701.

In the case 1702a, the lens 1
A liquid crystal panel 1704 is attached to the entire side surface on the 703 side, and a mirror 1705 is fixed at one end of the side surface at a predetermined angle. In addition, a driving circuit for a liquid crystal panel 1704 including a light source (not shown) is incorporated in the case 1702a, and light emitted from the light source is reflected by a mirror 1705 via the liquid crystal panel 1704 to form a lens for glasses. It is projected to 1703. Therefore, in this embodiment, the lens 1703 corresponds to the display unit 207 in FIG. The main part of the apparatus is incorporated in the case 1702b, and if necessary, an LED for performing communication, a photodiode, and a button switch for performing various settings are provided. Further, the pulse wave detection unit is built in the pad 1706,
The earlobe is sandwiched between these pads 1706 to fix the pulse wave detector to the ear.

<1-6-2-3: Card Type> As another embodiment, a card type as shown in FIG. 19 can be considered. This card type device is housed in the left breast pocket of the subject. Pulse wave detector 101 in this embodiment
Consists of a piezoelectric microphone provided on the card surface,
The number of beats is detected by detecting the subject's heartbeat, facing the subject's skin surface side. Thus, the pulse wave detector 10
When the alarm unit 208 generates an alarm sound, the alarm unit 208 detects the alarm sound. When the alarm unit 208 generates an alarm sound, the CPU 201 provided inside the apparatus performs a pulse wave detection unit It should be noted that a process that does not perform the beat detection by 101 is required.

<1-6-2-4: Pedometer type> As another embodiment, a pedometer type as shown in FIG. The pedometer apparatus main body 1900 is attached to a subject's waist belt as shown in FIG. The pulse wave detection unit 101 in this mode includes:
Like the wristwatch type shown in FIG. 5, it is worn between the base of the index finger of the subject's left hand and the second finger joint. At this time, the cable 501 connecting the apparatus main body 1900 and the main body pulse wave detection unit 101 does not hinder the movement of the subject.
It is desirable to take measures such as sewing on the outerwear.

<1-6-3: Aspects of Display and Announcement> In the first embodiment described above, the configuration in which the execution results of the first to sixth functions are all displayed on the display unit 207. However, as described above, the present invention is not limited to this. That is, the display is not limited to the display relying on the visual sense, and can be notified in various modes. In that sense, the announcement in the present invention means something that appeals to the five senses. For example, a configuration may be adopted in which a target traveling pitch, the number of beats, or the like is notified by appealing to tactile sensation by vibration or the like, or a configuration in which a result to be announced is appealed to auditory sense by voice synthesis to be announced.

<2: Second Embodiment> Next, a second embodiment of the present invention will be described.
An embodiment will be described. In the above-described embodiment, the stride in the running exercise is modified according to only the running pitch and the altitude difference (that is, the gradient). However, the stride also varies according to the number of beats in the running exercise. It is possible. Therefore,
In this regard, it can be said that the first embodiment has a disadvantage that the calculation result involving the stride tends to be inaccurate. Therefore, in the second embodiment, when the calculation is performed using the stride, the reference stride stored in the second storage unit 131 is corrected in consideration of not only the running pitch and the altitude difference, but also the beat pitch. Thus, the above-mentioned drawback is intended to be eliminated.

For this reason, the configuration of the exercise index measuring apparatus according to the second embodiment is as shown in FIG. 23, and is different from the configuration of the first embodiment shown in FIG.
53 is added. This third table 1
Reference numeral 353 stores the relationship between the number of beats and the third correction coefficient for multiplying the reference stride in advance, and outputs the latter corresponding to the former.

Here, a method of creating the third table 1353 will be described. Since this relationship is considered to differ greatly from subject to subject, as in the case of the first table 1351 or the second table 1352, the general relationship prepared in advance is determined by actual measurement of the subject itself. It must be edited and used according to the characteristics. First,
Considering the general relationship, it is thought that the stride becomes shorter as the beat rate increases,
As shown by the solid line in FIG. 24, the relationship prepared in advance also increases as the ratio to the reference pitch increases.
It is sufficient if the first coefficient to be multiplied by the reference stride becomes gradually smaller. Next, it is necessary to edit the relationship shown by the solid line according to the characteristics of the subject, and as shown by the broken line in the figure, according to the characteristics of the subject itself.
For example, the following method is possible. That is, first, the subject performs a running exercise at a reference pitch on a flat road, detects the beat rate (reference beat rate) at that time, and, second, increases the pitch stepwise by, for example, 10%. Run, measure the beats at each stage and the actual stride,
Third, the ratio of the actually measured beat rate to the reference beat rate and the ratio of the actually measured stride to the reference stride are calculated. 4th
In addition to plotting the ratio to the reference beat rate and the ratio to the reference stride, interpolate between the plots,
The characteristic shown by the dashed line in FIG. 24 is finally obtained. Of these, the calculation, plotting and interpolation of the ratio
U201 can be imposed, and the storage of the obtained characteristics can be imposed on the RAM 203, so that the user substantially needs to store the actual number of beats and stride in each stage by using the operation unit. It is only necessary to input through 206. The third table 1353 is described in the RAM 203 in FIG.
Therefore, there is no component substantially added in FIG.

When the subject actually performs a running exercise, RA
When calculating using the reference stride stored in M203, if there is an altitude difference, CPU 201
Then, the ratio of the running pitch to the reference pitch is determined, and RA
With reference to the first table 1351 stored in M203, the first correction coefficient corresponding to the ratio is read, and the second correction coefficient corresponding to the obtained altitude difference is read with reference to the second table 1352, Further, a ratio of the obtained number of beats corresponding to the reference number of beats is obtained, and the third table 135
3, a third correction coefficient corresponding to the ratio is read out, and secondly, the reference stride stored in the second storage unit 131 is multiplied by the first, second, and third correction coefficients, and The reference stride is corrected according to the running pitch, the altitude difference, and the number of beats.
The traveling speed is determined by multiplying the determined traveling pitch. On the other hand, if there is no altitude difference, the CPU 201 first obtains the ratio of the running pitch to the reference pitch, reads the first correction coefficient corresponding to the ratio with reference to the first table 1351 stored in the RAM 203. At the same time, the ratio corresponding to the reference beat of the running beat is obtained, and the third table 1353 is obtained.
, A third correction coefficient corresponding to the ratio is read out, and secondly, the reference stride stored in the second storage unit 131 is multiplied by the first and third correction coefficients to obtain the travel pitch and the corresponding travel stride. Correct the reference stride according to the number of beats,
Third, the running speed is obtained by multiplying the obtained stride by the obtained running pitch. Then, the exercise intensity is obtained from such a running speed. Thereby, the functional configuration shown in FIG. 23 is equivalently executed by the internal configuration shown in FIG.

According to the second embodiment, even if the pitch fluctuates in the running motion, the reference stride is corrected in accordance therewith, and the correction is performed in accordance with the characteristics of the subject. Therefore, the calculation using the stride can be performed more accurately.

[0100] In addition to the method of correcting the stride length using the first, second or third table described above, for example, the subject simply presses the button switches 511 and 51.
A method of manually increasing / decreasing the input stride length by pressing 2 is also conceivable. Further, the storage content of each table may be the stride value itself instead of the correction coefficient corresponding to the running pitch, the altitude difference, and the number of beats.

In the second embodiment, the first storage 135, the second table 1352, and the third table 1353 are used in the second storage unit 1 using three tables.
Although the configuration is such that the reference stride stored in the memory 31 is corrected, the configuration is not limited to this, and the configuration may be such that the correction is performed using one three-dimensional table in which the running pitch, the altitude difference, and the number of beats are used as arguments (parameters). However, in practice,
The disadvantage that the combination of the stride conditions to be measured, that is, the combination of the running pitch and the altitude difference becomes enormous and the burden on the subject increases, is the disadvantage that occurs in the same manner as in the first embodiment. is there.

<3: Others> Note that the first and second
In the embodiment, the exercise performed by the subject is run, but the present invention is not limited to this. For example, a similar effect can be obtained by setting the exercise to swimming, inputting the stroke distance of one stroke corresponding to the running stride, and detecting the number of strokes per unit time corresponding to the pitch. The same effect can also be obtained by assuming that the exercise is ascending and descending the table, inputting the amount of ascending and descending, and detecting the number of ascending and descending steps per unit time. In short, the present invention can provide, as a new exercise index, the exercise intensity in which the beat rate and the exercise pitch are synchronized in all the regular exercises performed at a constant rhythm, including the movement exercises normally performed in daily life. Becomes

[0103]

As described above, according to the present invention, the following effects can be obtained. The exercise intensity, which considers the physical and mental physical strength of the subject comprehensively and indicates the intensity of training necessary to increase the endurance of the whole body, is announced regardless of the type and location of exercise. (Claims 1, 2, 3, 4, and 9) Further, it is possible to know how the training result of the subject fluctuates along with the time transition (Claim 5). Further, it is possible to know the intensity of the exercise actually performed by the subject (claim 7). Since the exercise intensity is determined in consideration of the potential energy of the subject,
More accurate (Claims 6 and 8) When the exercise is a running exercise, the stride is corrected according to at least one of the number of beats, the running pitch or the number of beats. It is possible to obtain it more accurately (claim 10). Here, regarding the stride, when traveling on a flat road, the altitude difference is not considered, and at least one of the number of beats or the traveling pitch is considered for the stride. , The altitude difference is also taken into account.
1). When the subject is traveling downhill, it is possible to prevent the exercise speed from becoming unduly excessive and the exercise intensity excessive (claim 12). It is possible to easily reach the training intensity in the case of performing the continuous exercise (claim 13). If the training intensity has not been reached, a specific instruction can be received, and if it has been reached, it is possible to know that. It is possible (claim 14). By sending and receiving information to and from external devices,
It is possible to analyze the measurement result in an external device or to set a target value finely (claims 15 to 20).
