中外优秀男运动员百米动作速度时空结构的运动学特征

Kinematics Characteristics of Spacial and Temporal Structure of Movement and Speed in 100m Race of Elite Men Players at Home and Abroad

通过文献资料、高速摄像和对比分析的方法,对中外男运动员百米途中跑一个单步的步长、步时及人体重心轨迹进行研究,制定了短跑运动员所应达到的步频、步幅范围与跑速之间关系的模式表,为教练员科学训练提供了依据。

Through literature, high -speed photography and comparison, the author studies length, time, and gravity trajectory of a single step, and sets up a correlative mode table of step frequency, stride and speed that racers should reach in order to provide a reference for coaches＇scientific training.
