A research on action construction in three stages of triple jump for the Chinese elite female athletes

With the help of document reference,photograph analysis and mathematical statistics,this article made a quantitative description of the action construction in the three stages of triple jump of the Chinese elite female athletes. It was concluded that the action structure of the first and second jumps is good for keeping horizontal speed,while that of the third is helpful in increasing rush capacity. However,since the female athletes are not adept in skills and have weak brace capacity,the buffer becomes stronger in the second and third jumps. This leads to the loss of the horizontal speed,smaller vertical speed and unreasonable soar angle.
