我国优秀女子链球运动员旋转技术的运动学特征分析

Analysis on the Kinesiological Feature of the Spinning Technique for Chinese Talent Female Weight Throwers

对2007年全国田径大奖赛总决赛女子链球前6名运动员旋转技术中单、双脚支撑时间分布,链球加速途径,重心变化等情况进行运动学分析。结果表明,我国女子链球运动员的旋转总时间较长;单、双脚支撑时间分配不合理;随旋转圈数增加,链球球速增量递减。今后延长运动员双脚支撑时间、加强快速力量训练、提高旋转速度等有助于提高我国女子链球成绩。

A kinesiological analysis on the spinning technique of top six female weight throwers for the finals of 2007 National Track and Field Competition reveals that the spinning time of Chinese weight throwers is comparatively long, but the time distribution for single and both leg support is unreasonable and with the increase in the spinning circle, the ball speed drops. Prolonging the time for both leg support, enhancing training of explosive strength and increasing the spinning speed can improve the performance of Chinese female weight throwers.
