摘 要:采用文献法、录像解析法、访谈法等研究方法,以6名国家女子网球运动员为研究对象,对底线反手切削球关键技术动作进行三维录像和解析.结果表明:对不同高度的来球,反手切削球引拍和挥拍的动作不同,依动作特点可分为切削、平削和压削3种类型.运动学分析发现:3种切削球技术动作在转体引拍和挥拍切削时的肩髋转动角、拍面角、身体倾斜角有着显著的差异,3种技术的挥拍动作均有转体、拍臂依次加速的鞭打动作.该技术类型的新划分可为进一步提高网球教学和训练提供理论参考.Three-dimensional videos and analysis of the key techniques and movements of backhand chops on the bottom-line are made by means of literature consultation, video analysis and interviews and by studying 6 players in the national women's tennis team. Results show that the action o backhand chops varies with the height of the categories according to their characteristics: f coming ball and the action can be divided into three cut-slice, truncate-slice and press-slice. Kinematic analysis reveals differences of the three categories in shoulder and hip rotation angle, racquet face, and body tih angle and they all contain body swivel and accelerated whiplash movement. The new classification can provide a theoretical reference for further improving tennis teaching and training.
