Biomechanical Analysis On Final Enforce Movement Of Shot Put Athlete’s Fengjie

As the shot put technique principle and practice developed, we discovered that ifwe want to ensure the highest early speed, we need to make sure the perfect techniquemovement rhythm and the reasonable final force. This study taking the excellent shotput athlete of Xi’an Institute of Physical Education Feng Jie, and the elite men’s shotput athlete Wang Guangpu as example, using literature review, expert interviews,high-speed cameras and three-dimensional force platform synchronized test mode,makes a measured observation based on kinematics and dynamics when the twoplayers doing the movement of throwing shot put. This observation made a sentinelsynchronization test by using two high-speed photo cameras and the force platform, inpurpose of collecting the video image of throwing shot and the date of the finallyforcibly phase support reaction force. And then, combining the mechanics principle offinal push, the author made a comparison analysis and a diagnostic descriptionbetween the two shot put players which based on personal technology character,hoping to provide a reference for the technical training in Feng Jie.The results showthat: in the finally throwing phase, compared with our state’s other elite athletes, FengJie has below characters: his body’s center of gravity highest speed is much lower and,sooner; the final throwing time is too long; the time of his body by the side of the bowto the time of the anti-bow is too long; the rotation of the right hip and right legkicking is not so positive. The timing of shot speed suddenly increased is not the sameso the shot speed suddenly increased to establish the basis of the speed of the center ofgravity of the lower body, reducing the utilization of the speed of the center of gravityof the body.Our state’s players generally drawback to early acceleration in the rightshoulder, upper body prematurely accelerated to the throwing direction, the linksforce of order less reasonable, the contrary aspects accelerated the principles ofmechanics, should be improved in the future training.Compared with other elite players, Feng Jie’s shot height and shot degree are nodifferences than others, but his shot speed is a little bit lower, and his last strengthtime needs longer time, that was mainly due to the flexibility of his hip’s rotation andthe frequency of the right leg pedaling, especially the left leg. That’s why his final strength time needs more time.
