| 摘 要： | 采用高速摄像、录像解析及比较分析方法,对我国优秀标枪运动员陈奇投掷步相关运动学参数进行比较分析。结果发现陈奇投掷步的技术特点:助跑距离较长、助跑速度较快,第二交叉步前后速度损失同投掷成绩呈负相关;第一交叉步前后身体重心速度的增加幅度同交叉步前后躯干后倾角变化量呈负相关,第二交叉步前后身体重心速度的损失幅度同交叉步前后躯干后倾角变化量呈负相关;最后一步前后身体重心水平速度的损失幅度同躯干后倾角变化量呈正相关。

| Abstract: | By using the methods of high-speed photograph,photographic analysis and comparative analysis,it made a comparative analysis of the kinetic parameters related to the throwing steps of CHEN Qi,first-class javelin thrower of our country.His technical characteristics have been summarized as follows: opproach distance is longer,approach velocity is faster and the loss of velocity before and after the second cross step negatively correlates with throwing result;the range of increment in the velocity of center of body weight before and after the first cross step negatively correlates to the changing volumn of the angle of thunk leaning back before and after the cross step,and the range of the velocity loss of center of body weight before and after the second cross step also negatively correlates with the changing volumn of the angle of thunk leaning back before and after the cross step;and the range of the loss of horizantal velocity of center of body weight at the last step positively correlates to the changing volumn of the angle of thunk leaning back. |
