江西男子链球运动员旋转技术的运动学分析

A Kinematical Analysis on Spinning Technique of Elite Male Hammer Throwers in Jiangxi Province

通过高速摄影及影片解析,对王震与中外优秀男子链球运动员的旋转技术特征进行了运动学分析,结果发现,王震与国内外优秀选手相比,在旋转时单、双支撑时间分布、链球加速途径,重心位变化及链球运行斜面变化等方面存在着一些问题.根据存在的问题,提出了一些建议,以供训练时参考.

By means of speed photography and viedo analysis, the paper performs a kinematic analysis of characteristics of the spinning technique of Wangzhen and other foreign top male athletes. Results show that, compared with other foreign top athletes, Wangzhen has such problems as the single or double supporting time, the speed-up path of hammer, the change of gravity and the movement change on the inclined plane of hammer. Then some advice is proposed as reference in the future training.
