| 摘 要： | 对2007年全国田径冠军赛男子跳高项目前六名运动员最好一次试跳起跳技术进行三维运动学分析，结果表明：被试H2远低于世界优秀选手；根据起跳时运动员质心降低的方式，将本次跳高运动员起跳技术分为三类：低-高型、高-低型、低-平型；助跑平均水平速度和起跳垂直速度分量小；起跳阶段水平速度损失值与起跳离地瞬间重心垂直速度呈显著性正相关性；起跳腿离地瞬间膝关节蹬伸较充分。

| Abstract: | This paper studies six best male high jumpers＇ takeoff technique of the 2007 Athletics Championship of China with three-dimensional kinematics analysis method. The result shows that the mean value of H2 of these subjects is far lower than that of the elite of the world. The takeoff techniques of these subjects can be divided into the three types： Low-high. High-low. Low-flat by athletes＇ center of mass of takeoff. Both the run-up horizontal velocity and the take-off vertical velocity are low. The loss of horizontal velocity and vertical velocity at the instant of the take-off presents significant positive correlation. The knee joint stretch of the subjects is comparatively abundant. |
