[0002] The foot is the end of the human body's movement chain and is the only part of the body that is in direct contact with the ground during actions such as standing, walking, and running. Therefore, the strength of the foot muscles plays a vital role in the static stability control and dynamic movement of the human body.

[0003] The foot muscles are divided into intrinsic foot muscles and extrinsic foot muscles. Since the former have plantar muscle tendon attachment points on the foot, they mainly play a role in local stability. The latter muscles start from the calf and cross the ankle to attach to the sole of the foot, so their main function is to propel the body forward. When running in different types of running shoes, the elasticity and stiffness of the runner's plantar muscle tissue can be adaptively adjusted according to the hardness of the sole and insole. They can provide arch support and shock absorption on the one hand, and absorb impact and push the body forward on the other hand, like a spring, to meet their different needs on different running surfaces.

[0004] Despite this, existing studies on human muscle strength have mostly focused on large muscle groups in the thigh and calf that are easier to measure, such as the quadriceps, hamstrings, tibialis anterior and gastrocnemius. The plantar muscles have been largely neglected due to their relatively small anatomical structure.

[0005] Therefore, the present invention provides a training and testing device for multiple muscles of the sole of the foot and a method of using the device. Summary of the invention

The method for using the training and testing device for multiple muscles at the sole of the foot according to claim 7, characterized in that: The training methods for different muscles of the sole of the foot are as follows: The big toe is provided with an S-shaped hook (13), one end of the S-shaped hook (13) is connected to the sensor (5), and the other end of the S-shaped hook (13) is hooked with the big toe, and the big toe is bent to exert force, so as to pull the S-shaped hook (13) and apply tension to the sensor (5); The remaining four toes are provided with a first T-shaped bar (7), and the first T-shaped bar (7) with a corresponding angle is selected according to the size of the tester's foot, the first longitudinal bar of the first T-shaped bar (7) is connected to the sensor (5), and the remaining four toes except the big toe are hooked on the two horizontal bars, and the four toes are bent to exert force, so as to pull the first T-shaped bar (7) and apply tension to the sensor (5); Five toes, providing a second T-shaped rod (8), and selecting the second T-shaped rod (8) with a corresponding angle according to the size of the tester's foot, connecting the second longitudinal rod of the second T-shaped rod (8) to the sensor (5), and hooking the two arc-shaped rods with the five toes, bending the five toes to exert force, pulling the second T-shaped rod (8) and applying tension to the sensor (5); The first metatarsophalangeal joint is provided with a tension band (9), one end of the tension band (9) is connected to the sensor (5), and the other end is connected to the big toe, and the big toe exerts force downward to pull the tension band (9) and apply tension to the sensor (5); The intrinsic muscles of the plantar are provided with an arc plate (15), the convex surface of the arc plate (15) is connected to the sensor (5), the dorsum of the foot is matched with the concave surface of the arc plate (15), the plantar muscles are contracted and the dorsum of the foot is lifted up, the arc plate (15) is pushed and a thrust is applied to the sensor (5).

9. The method for using the training and testing device for multiple muscles at the sole of the foot according to claim 8, characterized in that: The installation position and force generation method of the sensor (5) are different according to the different muscles to be trained. The specific installation method and force generation method are as follows: When training the big toe, the other four toes and the fifth toe, the sensor (5) is horizontally mounted on the inner side of the support bar (2), and a horizontal force is applied to the sensor (5) during training; When training the first metatarsophalangeal joint, the sensor (5) is vertically mounted on the adjustment rod (4), and a vertical force is applied to the sensor (5) during training; When training the intrinsic muscles of the plantar, the sensor (5) is installed at an angle on the lower side of the adjustment rod (4), and during training, a force vertical to the sensor (5) is applied forward and upward.

10. The method for using the training and testing device for multiple muscles at the sole of the foot according to claim 7, characterized in that: Before training, a first pad (10) and a second pad (11) are provided, and an appropriate number of the first pads (10) are placed in the support frame, and the middle and rear parts of the foot are placed on the first pads (10), and then an appropriate number of the second pads (11) are padded between the heel and the side of the support frame, so that the toes are suspended in the air and can be bent and exert force better.
