| 摘 要： | 采用两台SONY高速摄像机对当前我国优秀男子跳高运动员起跳前摆动腿支撑技术进行现场同步拍摄，运用爱捷运动录像反馈系统进行解析。结果表明：我国优秀男子跳高运动员在摆动腿着地瞬间，身体重心距摆动腿着地点的水平距离较大，在摆动腿缓冲阶段，部分被试摆动腿膝关节缓冲幅度过大，水平速度的损失较为严重；最后一步步长、步长／身高指数较小，与国外优秀运动员相比有显著性差异。

| Abstract: | By using two Sony high-speed cameras, the take off technique of Chinese elite men high jumpers was recorded live, and then ananlyzed by the feedback system of Ajie kinematic video. The result shows that the gravity centres of Chinese high jumpers are rather far from the point where the swinging legs landed at the instant that happened. In the buffering course of the swinging legs, the knee joints of tried legs partly buffered too much and this made the horizontal speed lower. Finally, both the distance of the last step and the rate of the last-step distance and the body are comparatively small, having a significent difference with foreign elite high jumpers. |
