摘　　要：通过使用三维立体摄影解析法获取辽宁省乒乓球直拍运动员反手横打侧挑技术上肢动作的运动学参数,对直拍横打侧挑技术进行运动学分析。侧挑技术按以下3个动作阶段进行分析:"引拍阶段""挥拍—触球阶段""随势挥拍阶段"。通过对各阶段所设定的运动学参数进行相关分析,并结合生物力学和生理解剖学的知识,找出每个环节运动的差异。通过比较分析使教练员和运动员认清该技术动作的鞭打运动原理和技术关键在于加强前臂小肌群快速收缩的爆发力,进而找出好的训练方法,帮助运动员改进该技术动作。By using the analytical method to obtain three dimensional photography pen tennis players in Liaoning province playing on pen hold backhand side pick kinematic analysis techniques. The action re- search techniques in the following three stages of analysis： the racket phase, swing - touch ball stage, with the keeping swing stage. Through the various stages of the kinematic parameters set by correlation analysis, combined with biomechanieal and physiological knowledge of anatomy, to identify differences in each stage of the skill, through the comparative analysis, to recognize the coaches and athletes technique of the scourge movement is to strengthen the key technology and principle of small muscle contraction fore- arm of explosive and the key technology to find a good training method, helping athletes to improve the technical action.
