<< First Embodiment >>
(Training machine)
FIG. 1 is an external perspective view of a training machine 101 according to the first embodiment. FIG. 2 is a left side view of the training machine 101.

  The training machine 101 includes a seating portion 1, a backrest portion 2, a seat frame 3, support members 4A and 4B, a base frame 5, a connecting member 6, an action member 11, a constant velocity damping damper 21, contact portions 8A and 8B, 9A, 9B, multifunction module 31 and the like.

  The seating unit 1 is a part where a person who performs muscle contraction exercise using the training machine 101 (hereinafter referred to as “user”) is seated. The contact portions 8A, 8B, 9A, and 9B are portions that fix the user's ankle when performing muscle contraction motion.

  The training machine 101 according to the present embodiment is a training machine for isokinetic exercise (isokinetic muscle contraction exercise) used for muscle training, exercise therapy, and the like. Specifically, the training machine 101 is a seated leg curl machine for training a hamstring muscle by repeatedly extending and bending a knee joint while a user is in a sitting position.

  The seating portion 1 and the backrest portion 2 are fixed to a seat frame 3 bent in a U shape. The seat frame 3 is connected to the base frame 5 via support members 4A and 4B. A connecting member 6 is attached to the first end of the seat frame 3 (left end in FIG. 2). The connecting member 6 includes a rotating member 7 that rotates about the axis AX.

  The action member 11 is a long arm member that is periodically displaced by a user performing muscle contraction exercise. The first end of the action member 11 (the upper end portion of the action member 11 in FIG. 2) is connected to the rotating member 7 of the connecting member 6. That is, the action member 11 is pivotally supported by the connecting member 6, and the action member 11 rotates around the axis AX when the user performs muscle contraction motion (when the user repeatedly extends and bends the knee joint). (See arrow in FIG. 2). Abutting portions 8A, 8B, 9A, 9B and the like are attached to the second end of the action member 11 (the lower end portion of the action member 11 in FIG. 2).

  The multi-function module 31 is a small module that measures training data when a user performs muscle contraction exercise, and is provided directly on the surface of the action member 11. The multifunction module 31 according to the present embodiment includes a stress sensor, a gyro sensor, a short-range wireless communication module, and the like. The short-range wireless communication module is a module for communicating training data obtained from the stress sensor and the gyro sensor when the user performs muscle contraction exercise to the outside. The multifunction module 31 is, for example, a SimpleLink SensorTag CC2650STK manufactured by Texas Instruments.

  The constant velocity damping damper 21 is connected to the action member 11 and the support member 4A. As will be described in detail later, the constant velocity damping damper 21 has a damping characteristic corresponding to the force applied to the action member 11 by the muscle contraction movement, and approximates the action member 11 when the user performs the muscle contraction movement. This is a damper that is displaced at a constant speed. The constant velocity damping damper 21 is, for example, a hydraulic damper.

  This constant velocity damping damper 21 is an example of the “constant velocity displacement member” in the present invention.

  Next, a specific configuration of the constant velocity damping damper 21 will be described with reference to the drawings. 3A is an external perspective view of the constant velocity damping damper 21, and FIG. 3B is a cutaway view of the constant velocity damping damper 21. FIG. 4 is a sectional view of the constant velocity damping damper 21. FIG. 5 is a perspective view of the inner cylinder 41. 6A is a front view of the inner cylinder, and FIG. 6B is a cross-sectional view taken along the line AA in FIG. 6A. 3A, 3B, and 4, the configuration of each part is illustrated in a simplified manner.

  The constant velocity damping damper 21 includes a cylinder 40, a rod cover 43, a cylinder cap 44, a piston 51, a piston rod 52, variable throttles 45 and 46, groove portions 61 and 62, and the like.

  The cylinder 40 has a double cylinder structure in which an inner cylinder 41 having a smaller inner and outer diameter than the outer cylinder 42 is disposed inside the outer cylinder 42. The inner cylinder 41 and the outer cylinder 42 are both cylindrical members whose extending direction (axial direction) coincides with the A axis. A communication path 73 is formed between the inner cylinder 41 and the outer cylinder 42.

  The piston 51 is a columnar member that is fitted inside the inner cylinder 41 (cylinder 40) and is slidably disposed inside the inner cylinder 41. The piston 51 slides inside the internal cylinder 41 to separate the inside of the internal cylinder 41 into a first fluid chamber 71 and a second fluid chamber 72. The piston rod 52 is a rod-shaped member that moves along the extending direction (A-axis direction) of the cylinder 40. The piston 51 is connected to the first end of the piston rod 52 (the right end portion of the piston rod 52 in FIG. 4). Therefore, the piston 51 slides inside the inner cylinder 41 by moving the piston rod 52 in the extending direction (A-axis direction).

  A rod cover 43 and a cylinder cap 44 are fitted to both ends of the cylinder 40 in the extending direction. Thereby, the fluid (for example, hydraulic fluid) which is not illustrated is enclosed in the cylinder 40. The piston rod 52 is inserted through a hole formed in the rod cover 43, and a part thereof extends to the outside of the cylinder 40.

  The rod cover 43 is formed with a first reservoir chamber 74A and orifices 75A and 76A. The cylinder cap 44 is formed with a second reservoir chamber 74B and orifices 75B and 76B. The first fluid chamber 71 and the second fluid chamber 72 separated from each other by the piston 51 communicate with each other via the first reservoir chamber 74A, the second reservoir chamber 74B, the orifices 75A, 75B, 76A, 76B, and the communication passage 73. doing. When the piston 51 slides in the internal cylinder 41, the fluid sealed in the cylinder 40 moves between the first fluid chamber 71 and the second fluid chamber 72. The variable throttles 45 and 46 are members for controlling the cross-sectional area of the orifices 75A and 75B, and are, for example, speed adjustment valves.

  As shown in FIG. 6B and the like, two grooves 61 and 62 are formed inside the inner cylinder 41. The groove portions 61 and 62 adjust the flow passage cross-sectional area of the fluid flowing between the first fluid chamber 71 and the second fluid chamber 72 when the piston 51 slides inside the inner cylinder 41, This is a groove provided to move the rod 52 (piston 51) approximately at a constant speed.

  The groove portions 61 and 62 according to the present embodiment are formed deeper as they are separated from the predetermined position (near the center in the extending direction of the inner cylinder 41 in FIG. 6B) in the extending direction (A-axis direction). When the piston 51 moves inside the inner cylinder 41, the fluid flows between the first fluid chamber 71 and the second fluid chamber 72 through these grooves. That is, the groove portions 61 and 62 formed inside the inner cylinder 41 also serve as fluid flow paths.

  Next, a mechanism for adjusting the flow path cross-sectional area of the fluid flowing between the first fluid chamber 71 and the second fluid chamber 72 when the piston 51 slides inside the inner cylinder 41 will be described. Will be described with reference to FIG. 7A is a cross-sectional view showing the constant velocity damping damper 21 before sliding the piston 51, and FIG. 7B shows the constant velocity damping damper 21 in the middle of sliding the piston 51. FIG. 7C is a cross-sectional view showing the constant velocity damping damper 21 after the piston 51 is slid.

  As shown in FIG. 7A, when the piston 51 is separated from the predetermined position in the extending direction (A-axis direction), the piston 51 is moved in the first direction (+ A direction; see the arrow in FIG. 7A). )), The groove 61 formed inside the inner cylinder 41 is deep, so that the cross-sectional area of the fluid flowing from the first fluid chamber 71 to the second fluid chamber 72 is large. For this reason, when the piston 51 moves from a predetermined position in the extending direction (A-axis direction), the fluid flow resistance of the piston 51 is lower than that of the piston 51 that moves inside the inner cylinder 41.

  On the other hand, since the groove portion 61 becomes shallower as it approaches the predetermined position, the flow path cross-sectional area of the fluid becomes smaller as the piston 51 further moves toward the predetermined position. Therefore, as the piston 51 moves toward the predetermined position, the fluid flow resistance of the piston 51 that moves inside the inner cylinder 41 increases.

  Next, as shown in FIG. 7B, when the piston 51 is at a predetermined position, the groove formed inside the inner cylinder 41 is shallow (or no groove is formed). Therefore, when the piston 51 is slid in the first direction (+ A direction; see the arrow in FIG. 7B), the flow path cross-sectional area of the fluid that flows from the first fluid chamber 71 to the second fluid chamber 72 Becomes smaller. Therefore, when the piston 51 is moving in the vicinity of the predetermined position, the fluid flow resistance of the piston 51 moving the inner cylinder 41 is high.

  On the other hand, since the groove portion 62 becomes deeper as it moves away from the predetermined position, the flow passage cross-sectional area of the fluid increases as the piston 51 moves away from the predetermined position. Therefore, as the piston 51 moves away from the predetermined position, the fluid flow resistance of the piston 51 that moves inside the inner cylinder 41 becomes lower.

  As shown in FIG. 7C, when the piston 51 is separated from the predetermined position in the extending direction (A-axis direction), the groove 62 formed inside the inner cylinder 41 is deep, and therefore the inner cylinder 41 The flow resistance of the fluid is low with respect to the piston 51 that moves inside.

  The same applies to the case where the piston 51 slides inside the inner cylinder 41 in the second direction (−A direction) opposite to the first direction (+ A direction).

  As described above, the groove portion is formed deeper as it is separated from the predetermined position inside the inner cylinder 41 in the extending direction, thereby generating a high damping force at the predetermined position for the piston 51 moving inside the inner cylinder 41. Can do. Further, the damping force can be reduced as the piston 51 moves inside the inner cylinder 41 as the distance from the predetermined position increases.

  With this configuration, a characteristic that attenuates the moving speed according to the position of the piston 51 (piston rod 52) occurs, and a damper that displaces the piston 51 (piston rod 52) at a constant speed can be realized.

  The other end of the piston rod 52 of the constant velocity damping damper 21 (the left end portion of the piston rod 52 in FIG. 4) is connected to the action member (11), and the end 47 of the cylinder cap 44 of the constant velocity damping damper 21 is It is connected to the support member (4A). With this configuration, the user (11) rotates around the axis (AX) as the user performs muscle contraction, and the piston rod 52 of the constant velocity damping damper 21 is pushed into the cylinder 40 along with it. Or pulled out. Specifically, the piston rod 52 of the constant velocity damping damper 21 is pushed into the cylinder 40 in a state where the user has bent the knee joint (the state shown in FIG. 2). Then, as the user extends the knee joint (as the action member 11 rotates in the direction of the arrow shown in FIG. 2), the piston rod 52 of the constant velocity damping damper 21 is pulled out from the cylinder 40. .

  Next, it will be described with reference to FIG. 8 that the constant velocity damping damper 21 has a damping characteristic corresponding to the force applied to the action member 11 by the muscle contraction motion. FIG. 8 is a diagram showing the relationship between the force applied to the user's leg according to the knee angle and the load on the training machine 101 (action member 11). In FIG. 8, the horizontal axis indicates the knee angle of the user, and the vertical axis indicates the magnitude of the force. The unit of the vertical axis in FIG. 8 is an arbitrary value.

  As shown in FIG. 8, generally, the human leg exhibits the most muscular strength when the knee joint angle is about 60 °, and the muscular strength that can be exerted decreases with increasing distance from the angle. That is, the muscular strength exerted around 0 ° and 120 ° is low. The training machine 101 (action member 11) according to the present embodiment has the highest load at the position where the knee joint angle is about 60 °, and the lowest load at 0 ° and 120 °. That is, when performing a muscle contraction exercise using a training machine, a high load is applied at a position where the force is easily exerted, and a low load is applied at a position where the force is difficult to be exerted.

  Therefore, a user who performs muscle contraction exercise using the training machine 101 can easily perform approximate isokinetic exercise (isokinetic muscle contraction exercise).

(Training system)
Next, the training system according to the present embodiment will be described with reference to the drawings. FIG. 9 is a diagram showing a training system 501 according to the first embodiment.

  FIG. 10 is a block diagram illustrating functions of the multi-function module 31 provided in the training machine. The multi-function module 31 includes a stress sensor 110, a gyro sensor 120, and a data communication unit 130.

  The stress sensor 110 and the gyro sensor 120 are sensors that measure training data relating to a force applied to a working member that is displaced at a constant speed and a displacement speed (angular speed) when a user performs a muscle contraction exercise using a training machine. is there. The measured training data is communicated by the data communication unit 130 by short-range wireless communication.

Further, the data communication unit 210 receives training data transmitted from the data communication unit 130. The control unit 230 reads the training data received by the data communication unit 210 and calculates muscle power (described in detail later) based on the training data. Specifically, for example, the control unit 230 executes a program written in the memory 260 and calculates muscle power based on the training data.

  The training data or the muscle power data is transmitted via the communication unit 220.

  “Muscle power” refers to the mechanical power (work rate) of muscles. That is, the muscle power is the work amount of the muscle per unit time, and is obtained by, for example, force [N] × distance [m] / time [s] = force [N] × speed [m / s]. In general, in the measurement of muscle function, the muscle power represented by the product of force and speed is considered to be a more clinical index than the isometric muscle force exhibited when the joint does not move. In the training machine of the present invention, the muscle contraction exercise is performed at approximately the same speed, and thus the velocity [m / s] is approximately constant.

  FIG. 12 is a block diagram illustrating functions of the server device 301. The server device 301 includes a communication unit 310, a control unit 320, and a data storage unit 330.

  The communication unit 410 communicates with the communication unit 310 and the like illustrated in FIG. The control unit 420 is a microprocessor provided in the information processing terminal 401, for example.

  When operation unit 450 performs an operation (instruction) on a transmission request for training data or muscle power data stored in server device 301, control unit 420 transmits a transmission request from communication unit 410. Thereafter, the training data or the muscle power data transmitted from the server device 301 is received by the communication unit 410.

The control unit 420 may write the training data or muscle power data received by the communication unit 410 in the data storage unit 430.

  In the present embodiment, the communication unit 410 corresponds to “third data receiving means” in the present invention.

(A) The user performs isokinetic exercise (isokinetic muscle contraction exercise) while confirming his / her training data (force, angular velocity, muscle power, etc.) as needed by displaying on the display 240 of the communication terminal device 201. be able to.

(B) When performing a muscle contraction exercise using the training machine 101, the user can perform an isokinetic exercise without calculating the speed most efficient for muscle strength enhancement. For example, the most efficient speed for muscle strength enhancement for the user is calculated by the following method, for example.

  First, before performing the muscle contraction exercise using the training machine 101 (before starting the training), the user displaces the action member of the training machine 101 several times at the highest possible speed (MAX speed). The communication terminal device 201 calculates muscle power based on the MAX speed and the load of the training machine 101 (action member), and stores the calculated muscle power. Then, the communication terminal device 201 calculates the most efficient speed for enhancing the muscle strength for the user from the muscle power at this time. Note that there is a correlation between muscle strength and exercise speed, and the maximum muscle strength of the user can be extrapolated from this muscle power. In general, when muscle contraction exercise is performed at about 30% to about 35% of the maximum muscle strength, it is considered that the muscle is used most efficiently (the highest muscle work rate). Therefore, the most efficient speed for muscle strength enhancement for the user who performs muscle contraction exercise using the training machine 101 can be calculated from the muscle power at this time.

(C) When a user performs a muscle contraction exercise using the training machine 101, an instruction by sound from the communication terminal apparatus 201 or an instruction by display on the display 240 of the communication terminal apparatus 201 can be performed. The user can easily perform an isokinetic exercise simply by exercising as instructed above.

  In addition, by giving the above instruction from the communication terminal device 201 like a game program, it is possible to increase the motivation of the user who performs the muscle contraction exercise.

(D) The user's training data is stored in the communication terminal device 201 as a history, and a comparison with the previous training data, changes in muscle function (muscle strength), and the like are displayed on the display 240 by the program of the communication terminal device 201. Can be displayed.

(E) By storing user training data in the server device 301 from the communication terminal device 201 via the network 90, the training data can be used in various fields.

(F) Further, by storing the training data of a plurality of users in the server device 301, the training data of the plurality of users is displayed on the display 240 of the communication terminal device 201 (or the display 440 of the information processing terminal 401). It is also possible to display statistics and the like.

The training system of the present invention may be configured by the multi-function module 31 and the communication terminal device 201 included in the training machine 101. That is, the server device and the information processing terminal are not essential in the training system.
