根据对跑的时相划分的通常习惯,在一个周期步(复步)中,一侧腿与地面接触的阶段为支撑,而该侧腿蹬离地面(经腾空、界侧腿支撑及腾空)到它再次着地前瞬间的阶段为摆动。我们以前的研究结果表明,优秀短跑运动员一侧腿的支撑时间仅占一个复步时间的22.1%,而摆动时间却占77.9%,两者之比为1∶3.5。因此我们认为摆动是短跑技术的一个不可忽视的重要环节。美国人迪尔曼也指出摆动是跑的动作中一个重要的因素。多年来虽有一些学者对跑的摆动进行过研究,但对短跑摆动的专门研究不多,虽有一些研究涉及到短跑,但研究对象的水平都较低。
According to the usual habit of dividing the run-time phase, in one cycle step (re-step), the stage in which one leg is in contact with the ground is the support, and the side leg is kicked off the ground (vacated, bounding leg support and vacated) To the moment before it again landing the stage for the swing. Our previous results show that the support time for one side of the elite sprinter is only 22.1% of one stomp time, while the swing time accounts for 77.9%, the ratio of the two is 1: 3.5. Therefore, we think that swinging is an important and important part of sprint technology. American Deeleman also pointed out that swinging is an important factor in running. Although some scholars have studied the running wobble for many years, the research on the dash wobble has not been much studied. Although some researches involve sprints, the research subjects are all at a low level.
