本文对我国几名优秀跳高男运动员在实际比赛中跳高起跳动作进行研究,运用影片解析仪获得数据并经计算机处理,发现我国优秀跳高运动员助跑最后三步人体重心和速度均有明显下降,助跑最后一步的步频不是提高(国外运动员最后一步步频增0.6步/秒)而是下降0.91步/秒,起跳速度5.282米/秒不亚于国外运动员,但起跳角(83～93°)大于国外运动员(74～83°),这恐怕是我国跳高运动员成绩不理想的运动学原因。
In this paper, several outstanding high jump male athletes in our country in the actual game high jump take the action to study the use of video analyzer data obtained by computer processing and found that China’s elite high jumpers in the last three steps of human body center of gravity and speed have dropped significantly, the last run The step frequency is not increased (the last step of foreign athletes increased by 0.6 step / second), but decreased by 0.91 steps / second. The takeoff speed of 5.282 m / s was as good as that of foreign athletes, but the takeoff angle (83 ~ 93 °) Athletes (74 ~ 83 °), this is probably the result of our high jumpers less than the kinematic reasons.
