| 摘 要： | 在查阅歇资料和调查访问的基础上，经过理论研究和实践论证后认为，人体水平加速的原动力是摇动腿的折叠前摆与支撑腿的快速伸髋在时空上的巧妙配合；支撑和摆动相互作用，相互影响，二在短跑的不同阶段所起的作用大小不同；提高摆动的速度和幅度是提高跑速的决定因素。

| Abstract: | On the basis of consulting literatures and investigating,the paper has analyzed a good many points through theoretical and practical method,and considered that:The original motive force of the body horizontal acceleration is the folding and swinging of the swinging leg and the treading of the supporting leg coordinate timing; supporting and swinging affecting each other and playing an important role in different phases; raising the speed and the lengths of the swinging is the decisive factor in sprint. |
