Kinematics study on "a double piked somersault with 540° twisting" air movement for top woman trampoline players

A double piked somersault with 540° twisting is quite difficult for woman's trampoline players,whose failing rate was topmost and was used most often for athletes' free movement in China.In this paper,the author comparatively analyzes the first,second,third and a fail athlete 803∠ air movement in 2011 Wuxi FIG Trampoline Gymnastics World Cup.It is hoped that movement technology diagnosis can provide information for athletes and coaches in training and competition.
