摘　　要：目的对国家乒乓球队男子主力运动员A反手拧拉技术进行动作分析与诊断,为进一步提高其反手拧拉技术质量提供依据。方法通过三维运动学测试与分析方法,加入定量数据与画面分析,对运动员A的反手拧拉技术与反手拧拉技术好的运动员B的技术动作进行对比。结果引拍阶段,运动员A引拍距离、肩角、腕角显著小于运动员B,躯干倾角显著大于运动员B。挥拍击球阶段,运动员A肩角、肘角显著大于运动员B,肩角、肘角增加幅度和躯干倾角变化幅度显著小于运动员B。随挥阶段,运动员A肩角、肘角显著大于运动员B,肩角、肘角增大幅度以及躯干倾角、躯干倾角变化幅度显著小于运动员B。结论运动员A引拍幅度较小,引拍结束时刻球拍与球的距离较近。击球过程中,击球点离身体较远,肩关节稳定支撑不够,手腕用力较多,重心向前压得不够,发力不集中。随势挥拍阶段,运动员A制动不够积极,影响其击球的稳定性。击球过程中,躯干扭转幅度小,腰部发力不集中。运动员A在不影响正手发力的基础上,对反手拧拉技术动作进行微调。适当加大引拍幅度和身体的扭转幅度,击球过程中,以腰发力带动前臂发力,进而带动手腕发力为主。Objective To make analysis and diagnosis on backhand twist technique used by player A,who is the leading men’s player of national table tennis team,so as to provide references for improving his backhand twist technique.Methods The three-dimensional kinematics test and analysis were used.The backhand twist techniques of player A and those of player B who has good backhand twist techniques were compared by quantitative data and picture analysis.Results At the stage of swinging racket backward,the racket swing amplitude,shoulder angle and wrist angle of player A were significantly smaller than those of player B.The roll angle of trunk of player A was significantly larger than that of player B.At the stage of swinging and hitting the ball,the shoulder angle,elbow angle of player A were significantly bigger than those of player B,while the increasing amplitude of shoulder angle and elbow angle,as well as the changing amplitude in roll angle of trunk of Lin Guoyuan were significantly smaller than those of player B.At the stage of swinging racket forward,the shoulder angle and elbow angle of player A were significantly bigger than those of player B.The increasing amplitude of shoulder angle and elbow angle,as well as the roll angle of trunk and its changing amplitude of player A were significantly smaller than those of player B.Conclusions The racket swing amplitude of player A was smaller,and the distance between the racket and the ball of player A was close at the end of swinging racket backward stage.During swinging and hitting the ball stage,the hitting point was far from the body,the shoulder joint was not stable enough to support,so that the wrist was used more.The center of gravity was not enough to force forward,and the outburst power was not concentrated.At swinging racket forward stage,player A’s braking was not active enough,which affected the stability of hitting the ball.At hitting the ball stage,the torsion of the trunk was smaller,and the waist power was not concentrated.On the basis of unaffecting th
