  Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

  Before describing the configuration of the exercise device of the present invention, the mechanism of the skeletal muscle to which the exercise device is attached will be described.

1. Skeletal Muscle Mechanism As shown in FIGS. 1 and 2, skeletal muscles are classified into longitudinal muscles and pterygium muscles according to their shapes.

  Longitudinal muscle is a general term for muscles in which muscle fibers are linearly arranged in the same direction as the muscle. Typical muscles are spindle muscles such as biceps brachii (see Fig. 1 (a)) and sewing. There are parallel bars (see Fig. 1 (b)) such as engineering bars.

  On the other hand, the pectoral muscles such as the quadriceps and triceps are muscles like a bird's wing in which muscle fibers are arranged diagonally with respect to the tendon. Single feathers (see Fig. 2 (a)) where the arranged muscles are only on one side, double feathers (see Fig. 2 (b)) on both sides, diagonally arranged, diagonally arranged There are multi-feathered muscles (see FIG. 2 (c)) in which many muscles are lined up side by side to form one muscle.

  The fusiform muscle has a property that it cannot generate a large force but has a fast contraction speed, and the feather muscle has a property that it can generate a large force although its contraction speed is slow.

  As the skeletal muscle contracts, the tendon is pulled, and the joint bends and extends.

  Since the muscle bundle and the tendon are parallel to the fusiform muscle and the parallel muscle, the direction in which the muscle contracts and the direction in which the tendon is pulled are the same, and the muscle contraction force is not impaired, and the motor output is obtained.

  On the other hand, since the pterygium has an angle (feather angle) between the direction in which the muscle contracts and the direction in which the tendon is pulled, the motor output is smaller than the muscle contraction force.

  If the loss of muscle contraction force is reduced by compression, the motor output can be increased. Therefore, the present invention focuses on the pterygium.

1.1 Wing Angle and Force Transmission Efficiency In FIG. 3 (a), if the force exerted by the muscle 1 when the wing muscle is not compressed is F and the wing angle is θ1, the force in the tendon 2 direction The component is F × cos θ1. That is, the force transmission efficiency from the muscle 1 to the tendon 2 is determined by the winged angle.

Next, as shown in FIG. 3 (b), when the pterygium muscle is pressed in the direction of arrow B and the wing angle becomes small, the force component in the tendon 2 direction becomes F × cos θ2,
F × cos θ1 <F × cos θ2
Therefore, when the pterygium muscle is compressed, it is possible to suppress a decrease in the force transmission efficiency from the muscle 1 to the tendon 2 as compared with the case where the wing angle is θ1.

  The pressure at this time is at least 20 hPa or more, preferably 100 hPa or more.

  Further, as shown in FIG. 4 (a), the direction of pressing the pterygium can be pressed from the direction orthogonal to the tendon 2 (arrow C direction). Preferably, the direction shown in FIG. As shown, it is more effective to press the tendon 2 from an oblique direction (arrow D direction).

  Specifically, when the object to be compressed is the thigh, pressing from the orthogonal direction means pressing the quadriceps muscle from the horizontal direction in a standing posture, and pressing from the oblique direction means pressing from the oblique direction. This is to press the head muscle diagonally upward from above the knee toward the back side.

  Also, when the compression target is the lower leg, pressing from the orthogonal direction means pressing horizontally from directly above the tension shin, and pressing from the diagonal direction means front side from the upper part of the rear side of the ankle It is to squeeze in the diagonally upward direction.

  Conventional compression by so-called compression wear is intended to reduce performance degradation due to muscle support, to improve posture, and to promote blood flow.

  These are only muscle support and did not improve the motor output to the outside of the muscle. Therefore, the pressure of the compression remains at most about 30 hPa.

  In addition, although a supporter having a taping effect can increase the compression pressure, its purpose is to protect joints, muscles, and tendons, which is different from the present invention that increases muscle output.

  In addition, the pressurized clothing for strengthening muscles shown in the background art does not increase the muscle exercise output during exercise.

2. Next, a method for measuring muscle exercise output will be described.

  The muscle contraction force was measured for the isometric knee joint extension (quadriceps) movement by the muscle contraction method induced by electrical stimulation.

  For stimulation, a rectangular wave of 200 μsec was sent to the thigh of the subject in the sitting posture. The electrode attachment positions for stimulation are the upper part and the lower part on the front side of the thigh.

  The stimulation frequency was 20 Hz, and the stimulation intensity below the pain resistance threshold of the subject was added.

  In addition, (a) when pressure is not applied, (b) when the hand is pressed in the direction of pushing up the thigh, (c) when pressed in the direction of pushing up the front of the thigh with a belt-like fabric having small stretchability, (d) Measurement was performed on four patterns when pressing in the direction of pushing down the front side of the thigh with a belt-like fabric having low stretchability.

  The pressure at the time of pressing was 90 to 200 hPa, and the pressure was measured by a plurality of pressure sensors attached to a portion of the thigh corresponding to the quadriceps muscle.

  In addition, the measurement of the muscle exercise output was performed by measuring the force with which the knee joint extends using a force sensor arranged so as to face the shin part and contact the shin part.

  FIG. 5 is a graph showing a procedure for applying electrical stimulation, where the horizontal axis indicates time (seconds) and the vertical axis indicates voltage (V).

  Considering the nature of muscles that increase the strength output of muscle strength after muscular activity at the maximum strength, it is necessary to align the conditions of muscle strength output. Therefore, after exerting the maximum strength, the above (a) to (d) Apply each pressure and apply electrical stimulation. In the figure, P indicates the electrical stimulation given after the maximum muscle strength is exerted.

2.1 Measurement Results FIG. 6 is a graph showing the average value of the exercise output of five subjects obtained by the above measurement method, and the horizontal axis shows the compression patterns (a) to (d), the vertical The axis indicates the motor output (N).

  As shown in the graph, (a) the case where pressure is not applied, (b) the case where pressure is applied in the direction in which the thigh is pushed up, and (c) the case where the thigh is pushed up with a belt-like fabric having low stretchability. A clear increase in motor output was observed between the case of pressing in the direction.

  On the other hand, when (d) the thigh was pressed in the direction of pushing down the thigh with a belt-like fabric having low stretchability, a decrease in motor output was recognized.

3. Next, the configuration of the exercise equipment for increasing the exercise output of the muscle will be described.

  At this time, if the distal end of the compression belt 82 reaches the pressure point 81f, the compression belt 82 functions as a compression unit that compresses the lower leg with a pressure of 90 to 200 hPa. As a result, the lower leg can be tightened with the exercise equipment 80, and the lower calf is pressed in the direction of arrow I (see FIG. 15 (b)), and at the same time effectively compressing the pectoral muscle of the gastrocnemius, The muscle-tendon transition part, which is the connection between the gastrocnemius and the tendon, can be pressed.

  In addition, if the compression belt 82 is tightened to the maximum with its own force without providing the pressure point 81f, the lower leg can be compressed with a pressure of 150 to 200 hPa.

3.7 About compression of muscle tendon transition part Tendon usually has slack, but if the slack is eliminated by applying pressure to the area including the muscle tendon transition part, the rise of force and tendon stiffness ( It has been found in the study relating to the present invention that the magnitude of the force on the unit length change of the tendon is increased. High tendon stiffness can increase exercise performance.

  Therefore, the effect of lower leg compression on tendon stiffness was examined.

  FIG. 16 is a graph comparing tendon stiffness in the case where compression is not applied to the muscle tendon transition portion and in the case where compression is applied. In the graph, the horizontal axis indicates the change in tendon length (mm) from the rest, and the vertical axis indicates the ankle plantar flexor strength (N).

  A characteristic P1 indicates ankle plantar flexor strength against a change in tendon length when no pressure is applied to the muscle tendon transition part, and a characteristic P2 indicates an ankle joint against a change in tendon length when compression is applied to the muscle tendon transition part. It shows plantar flexor strength.

  Tendon stiffness can be represented by the slope of a regression equation obtained from the relationship between muscle strength and tendon length after 50% MVC (Maximum Voluntary Construction).

  In the graph, the regression formula of the characteristic P1 is y = 486.68x−4425.3, and the regression formula of the characteristic P2 is y = 554.21x−2732.5. That is, it was confirmed that when pressure is applied to the muscle tendon transition portion, the tendon stiffness is improved from 486.68 N / mm to 554.21 N / mm.

  From this, the ankle plantar flexor strength increases in proportion to the amount of tendon extension, but even with the same tendon extension amount, applying pressure to the muscle tendon transition can improve the ankle plantar flexor strength. It can be seen that the tendon stiffness is improved.

  Therefore, higher compression performance can be obtained by compressing the pterygium muscle of the gastrocnemius muscle and at the same time compressing the muscular-tendon transition portion, which is the connection between the gastrocnemius muscle and the tendon.
