| 摘 要： | 为研究中外男子20km竞走运动员摆动技术的运动学特征，找出中外运动员的差异，主要采用文献资料法、三维影像解析法对4名中外男子20kill竞走运动员的摆动技术进行运动学分析，研究发现：现阶段世界级男子20km竞走运动员摆动技术的特征是上下肢在大幅度摆动的基础上保持较快的摆动速度，两腿膝关节在摆动过程中基本处于同一水平面；肩髋扭转角度是影响步长的重要原因之一，肩髋额状面夹角的大小决定着运动员肩关节和髋关节的摆动幅度；中国运动员需要减小两腿膝关节在摆动过程中的上下波动，增大肩髋扭转角和肩髋额状轴夹角，提高上下肢的摆动速度。

| Abstract: | In order to study the kinematic features on swing technique of Chinese and foreign men＇ s 20km race walk- er, find out the differences between them, this paper mainly by using the methods of literature, 3D camera and image analytical to analysis the swing technique of tour chinese and foreign men＇s 20km walking race. The study find out： at present, the characteristics of swing technique of world - class walking race are keep faster swing velocity based on the amplitude of swing and two knee joint swinging in the process of swing are in the same plane. The angle of shoul- der - hip reverse is one of the significant causes to influence strides. To a certain degree the angle of shoulder - hip in frontal plane decides the amplitude of swing of shoulder and hip. Chinese athletes need to reduce volatility in the process of knee joint in the swing, increasing the angle of shoulder - hip reverse the angle of shoulder - hip in frontal plane, and improve the swing velocity of upper and lower limbs. |
