网球底线反手切削球技术划分及运动学参数比较分析

Techniques Classification and Kinematics Analysis on the Backhand Chops at the Bottom Line in Tennis

采用文献法、录像解析法、访谈法等研究方法,以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:不同高度的来球其引拍和挥拍的动作不同,依据其动作特点可分为切削、平削和压削三种技术。分析发现:三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、身体倾斜角有显著差异;三种技术的挥拍动作均是由转体、拍臂依次加速的鞭打动作。以此研究揭示底线反手切削球技术的本质特征,为进一步提高网球教学和训练提供理论参考。

By means of the research methods of literature reviews, video analysis, experts interviews, statistics and so on, taking women national team players of tennis as the research subjects, the paper has analyzed the backhand chops tech- niques at the bottom line in the video. The results show that the technique action of the backswing and swing is according to the height of the ball. Based on their action feature, the author classifies the backhand chop into cut - slice, truncate - slice and press -slice. Statistics show that there are significant differences in the rotation angle of shoulder, kip, racquet face and inclination of body in two of the three technologies. However all the techniques are whippings which are to speed up from the twist of the body to swing of the arms. The study reveals the essential characteristics of the backhand chops ball techniques at the bottom line. The paper aims to provide the theory basis in teaching and training.
