对短跑技术中摆臂姿势分析

The Analysis on Sprint Technique of Arm's Position

前人对改进、提高短跑速度从步频、步幅、后蹬、摆动上都做了详细的研究。但忽略了一个问题 ,手臂摆动时到底是半握拳式好还是自然伸直好 ?一般教科书认为 ,摆臂动作应是半握拳式。文章通过对短跑技术进行力学分析后认为 ,在短跑运动中 ,手指在摆臂过程中应保持自然伸直为宜 ,自然伸直手指摆臂姿势优于半握拳姿势。

We study imporovement and brush up dash speed from the step frequency. Step breadth swing all did the detailed researched. But neglect a problem.
