KINEMATICAL ANALYSIS ON FORWARD HANDSPRING AND SALTO DOUBLE FORWARD PIKED OF HU JUNJIE IN MEN'S VAULTING HORSE

Forward handspring and salto double forward piked is oneof the most difficult movements in men's vaulting horse. Hu Junjie is theonly Chinese gymnast who brought this movement to success. Based on a 3Dmotion analysis, the kinematic features and the technical characteristicsof the forward handspring and salto double forward piked performed by HuJunjie are analyzed in this paper. The variations of some kinematicparameters, such as the displacements, horizontal and vertical velocities ofmass center, the displacements and angles of main joints are obtained. Theresults of analysis can provide a technical and theoretical guidance forfurther design of movements for Chinese gymnasts in this field.
