我国女子链球项目备战伦敦奥运会重点队员投掷技术的诊断分析

Throwing technics of Chinese female key hammer throw athlets while preparing for 2012 London Olympics

通过运用三维运动学分析的方法,对我国现役4名优秀女子链球选手的旋转技术进行研究发现:张文秀旋转阶段加速时机好,对器械的控制能力较强,加速节奏合理,符合掷链球技术的要求;王峥各圈单支撑时间过长,加速节奏较差;郝帅旋转过程中对器械的加速效果较差,身体对器械的控制能力差,节奏差;刘瑛慧一、二圈对器械的加速效果差,三、四圈加速效果好,加速节奏合理。

Abstract：Through the 3 - D kinematic analysis and on the basis of the rotation technique four Chinese elite female hammer throw players, we found that Zhang Wenxiu has a good acceleration at the rotating period, strong ability of hammer control, reasonable acceleration pace, which comply with the requirements of hammer throw technic. Single support of each circle is too long to Wang Zhen, and accelerating the pace is not good. Hao Shuai＇ s accelerating speed of the hammer is poor in the rotating process, and her hammer control and pace are also poor. Liu Yinghui＇ s first and second laps of hammer accelerating are not good enough, but the effect of accelerating in the third and fourth laps are good, and her pace is reasonable.
