江苏省部分优秀女子链球运动员旋转技术的三维运动学分析

The Three-Dimensional Kinematic Analysis on Spinning Technique of Some Female Elite Hammer Throwers in Jiangsu Province

采用2台JVC9800高速摄影机,对江苏省3名优秀女子链球运动员的旋转技术进行拍摄和解析,并对旋转阶段的单、双脚支撑时间分布、旋转时间递减率、肩髋角、链球运行斜面等进行运动学分析与比较。

By using two JVC9800 high-speed cameras, author recorded 3 female elite hammer throwers＇technique in Jiangsu Province and made kinematic analysis On the single Or double supporting stages, the spinning time lapse-rate, the angle between shoulder and hips and the movement of inclined plane of hammer.
