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、双脚支撑时问分布,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问、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。
對2007年全國田徑大獎賽總決賽女子鏈毬前6名運動員鏇轉技術中單、雙腳支撐時問分佈,鏈毬加速途徑,重心變化等情況進行運動學分析。結果錶明,我國女子鏈毬運動員的鏇轉總時間較長;單、雙腳支撐時間分配不閤理;隨鏇轉圈數增加,鏈毬毬速增量遞減。今後延長運動員雙腳支撐時問、加彊快速力量訓練、提高鏇轉速度等有助于提高我國女子鏈毬成績。

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.
