Velocity Change of the Body and Shot's Center Gravity in the Final Force Stage of Backward Sliding-step Shot-put
Haifeng Wu · Journal of Hebei Institute of Physical Education · 2012
The video analysis,documentation and contrastive analysis are used in this paper to analyze the body gravity and shot's velocity change of 12 backward sliding shot-put athletes in the final force.The result indicates that in the final force,the velocity change of body gravity and shot has shown the same features at first and the different features later and there is a turning point on shot's velocity change.
