Background technique

Takraw is a unique ancient sport with a long history. Athletes need to use their ankles, knee joints, etc. to clamp and head the ball at the same time, so as not to let the ball fall. Similar to the volleyball game, the difference is that the feet lead the hands, so it is also called "kicked volleyball". Since the feet lead the hands, the two feet need to play the takraw ball while maintaining the balance of the body, which affects the balance of the players. and ankle strength requirements are very high. In normal training, due to the low intensity of competition, the athlete's movement range is not large, so that the muscles of the ankle are adapted to the force under this range. , attacking and saving the ball will be more active than usual, making the overall competition more intense, and the athlete's range of motion is larger, exceeding the range of motion that the muscles can adapt to during normal training, increasing the pressure on the ankle muscles and increasing injuries.

This embodiment is based on the ninth embodiment. Specifically, as shown in FIG. 4 , in the step a, the athlete jumps off the platform 2 and touches the sphere. The lever plate 53 pushes the detection slider 54 to slide upwards, thereby triggering the detection switch 56 to detect the shaking of the takraw ball, and sending a signal to the controller.

Specific Embodiment Fourteen

This embodiment is based on the ninth specific embodiment. Specifically, as shown in FIG. 6 and FIG. 7 , when kicking the takraw ball, the gear on the translation motor 63 meshes with the translation rack 62 . When rotating, the translation rack 62 slides left and right, the translation rack 62 drives the translation slider 61 to slide left and right, and the takraw ball is reciprocated above the athlete through the sliding of the translation slider 61;

During training, the takraw ball is moved back and forth through the translation mechanism 6, which increases the difficulty of the athlete when kicking the takraw ball. When taking off, the athlete needs to adjust the timing of the jump and the direction of force according to the position of the takraw ball, so as to simulate the competition more realistically For complex situations, the muscles of the athletes' ankles can be exercised in different directions of take-off force, and the force of the athletes' feet in different directions can be enhanced, thereby reducing the athlete's cunning injury.

Embodiment 15

This embodiment is based on the ninth embodiment, specifically, as shown in FIG. 8 and FIG. 9 , when kicking the takraw ball, the gear on the driving motor 73 meshes with the annular rack on the upper end of the rotating inner ring 72 . , when the driving motor 73 rotates, the rotating inner ring 72 is rotated, and the rotation of the rotating inner ring 72 drives the takraw ball to move, so that the takraw ball moves in a circular trajectory above the athlete

During training, the takraw ball is moved in a circular trajectory above the player through the rotating mechanism 7, which increases the difficulty of the player when kicking the takraw ball. When the player takes off, according to the position of the takraw ball, the parts need to adjust the timing of the jump and the direction of force. , but also adjust according to the orientation between itself and the takraw ball to simulate the complex situation in the game more realistically. It can exercise the muscles of the athlete's ankle in different take-off and force directions, and enhance the athlete's foot in different directions. The force on the upper body, thereby reducing the situation of the athlete's cunning injury, and at the same time exercising to quickly adjust the pace of their own orientation;

Specific embodiment sixteen

This embodiment is based on Embodiment 9. Specifically, as shown in FIG. 10 , when kicking the takraw ball, by adjusting the gear on the drive motor 83 to mesh with the annular rack on the upper end of the inner fixed ring 82, When the driving motor 83 is adjusted to rotate, the inner fixed ring 82 is rotated, and the rotation of the inner fixed ring 82 drives the takraw ball to move, so that the takraw ball moves in a circular trajectory above the athlete. By sliding the fixed slider 87 on the vertical sliding rod 88 , the fixed slider 87 makes the second hinge rod 86 rotate, and the second hinge rod 86 makes the first hinge rod 85 rotate with the inner fixed rod 84 as the center of the circle, thereby changing the size of the center track of the takraw ball and the height of the takraw ball;

During training, the takraw ball is moved in a circular trajectory above the player through the takraw ball adjustment device 8, which increases the difficulty of the player when kicking the takraw ball. When the player takes off, according to the position of the takraw ball, the parts need to adjust the timing of take-off and the launch of the ball. The direction of force also needs to be adjusted according to the orientation between itself and the takraw ball. By changing the height and size of the takraw ball, the difficulty is further increased, and the complex situation in the game can be simulated more realistically. Exercise in different take-off force directions to enhance the force of the athlete's feet in different directions, thereby reducing the athlete's cunning injury.

The above embodiments are only exemplary descriptions of this patent, and do not limit its protection scope. Those skilled in the art can also make partial changes to them, as long as they do not exceed the spirit and essence of this patent, they are all within the protection scope of this patent.
