At the highest point of the board 6, two travel switches 29-1 control the moving mechanism 29 to stop moving, and close the power supply of the motor of the moving block 29-2 that is equipped with a drive motor. At this time, the athlete's throwing arm, waist and related muscle groups Full centrifugal elongation, that is, concentric contraction for the final hard exercise, while the balance training platform mechanism has information quantification monitoring, the trainer stands on the balance training platform mechanism 17 with information feedback in an unstable state, and combines the The optimized design is close to the special strength characteristics of the hammer throw. Finally, shake the bracket 2 vigorously, hold the handle 22 of the hammer throw training device with your hand, and perform the final vigorous practice. At this time, the balance training platform mechanism 17 with information feedback starts to work, and the balance mechanism is measured. The amplitude of the swing is quantified and processed, and converted into an electrical signal to connect with the motor 16-1 of the motor assembly 16 to generate interaction. With the improvement of the balance ability of the trainer, the balance mechanism tends to be stable when the trainer exercises At this time, the balance mechanism generates an electric signal to start the motor 16-1 of the motor assembly 16, so that the rocking support 2 will swing to increase the difficulty of new exercises.
