On the basis of document consultation,statistics,expert interview and biomechanical experiment and taking tornado feet turn 720° as an example,the paper analyses biomechanically the different stages of the movement and lists the experiment data for improving the success rate of the movement so as to provide theoretical reference for coaches and athletes in practising this kind of movements.

Biodynamical analysis of excellent Wushu routine player’s move of a whirlwind kick with a 720° turn followed by a horse-riding style halt;

It used the analytic method of sports biomechanical photographs to make a three dimensional analysis of the technique in the take-off stage of tornado kick turn 720° to horse step.

The whirl wind kick at 720° is .

Using the methods of video observation,biomechanical experiment and mathematical statistics,it analyzed Class B and Class C jumping difficulty of tornado kick in Wushu routine and the kinematic,kinetic and biologic characteristics of connecting difficult movements,and found that the take-off velocity of tornado kick was faster for the take-off with a single foot than that with double feet.
