摘要
前手翻屈体前空翻2周是男子跳马最高难度动作之一.迄今,我国只有胡俊捷曾完成该动作.本文通过三维运动学分析技术揭示了胡俊捷完成前手翻屈体前空翻2周动作的运动学规律与技术特点,获得了身体重心和主要关节的位移,水平速度和垂直速度及关节角度等运动学指标的变化.这些结果可为我国运动员发展和改进此类动作提供理论依据和技术参考.
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.
