论背越式跳高中摆动腿伸髋肌群的作用

On the Functions of Muscle Clusters of Extending Hip on Swing Leg in Flop

阐述了快速伸髋在获得助跑速度中的作用;从摆动腿的快速伸髋在保持最后一步助跑速度、形成好的起跳用力结构和起跳的摆动中所起的重要作用等三方面详细论述摆动腿的快速伸髋在背越式跳高助跑速度转化成起跳速度中的作用。以期对背越式跳高的项目特征有更深入的认识。

The paper shows the effects of the techniques of rapidly extending hip on the velocity of nmning up in the flop. The technique emphasizes keeping the speed of last step,and the good structure of the force of taking off, and the movement of swing leg in the phase of taking off. With the above three aspects, the functions of muscle dusters of extending hip in flop are researched in order to probe deeply into the event characteristics of the flop.
