KINEMATICAL ANALYSIS ON FORWARD HANDSPRING AND SALTO DOUBLE FORWARD PIKED OF HU JUNJIE IN MEN''''S VAULTING HORSE
胡俊捷跳马前手翻屈体前空翻2周运动学分析

Forward handspring and salto double forward piked is one of the most difficult movements in men's vaulting horse. Hu Junjie is the only Chinese gymnast who brought this movement to success. Based on a 3D motion analysis, the kinematic features and the technical characteristics of the forward handspring and salto double forward piked performed by Hu Junjie are analyzed in this paper. The variations of some kinematic parameters, such as the displacements, horizontal and vertical velocities of mass center, the displacements and angles of main joints are obtained. The results of analysis can provide a technical and theoretical guidance for further design of movements for Chinese gymnasts in this field.
