张择发球技术动作、战术运用改进前后的对比分析

The Comparative Analysis on the Serving Techniques and Tactics Application of Zhang Ze

为了进一步发现中国男子网球选手发球存在的问题并找出解决方法,选择国家队现役优秀男子选手张择作为研究对象,运用数理统计法,使用高速摄像机采集数据,对张择动作改进前后的各项数据进行详细的对比、分析,运用文献资料法、观察统计法对他在2015年参加高级别ATP赛事时的发球速度、落点分布等环节进行了细致、深入的观察与研究,从而可以得出其现有的发球技术动作较改进前的动作结构更加合理,不过在抛球高度、"搔背"动作等环节方面依然存在问题,仍有改进的空间。

In order to further find the existing serving problems of Chinese men tennis players and get solutions,the author selected the active service excellent men player of national team Zhang Ze as the research object,made detailed comparison and analysis on all the data before and after improvement with method of mathematical statistics and high speed camera to collect data. Documentary methods and observation statistics have been used to carefully and deeply observe and research his serving speed,the distribution of falling points and other steps in the high level ATP events of 2015. We could get the conclusion that present serving technique is more rational than the previous movement structure before improvement and there are still problems on the height of the toss and the movement of＂scratching back＂,which still have room for improvement.
