对短跑运动员途中跑踝关节技术的研究

Research into the skill of ankles during the steady running for sprinter

通过对短跑运动员途中跑踝关节技术的比较研究,探讨了踝关节技术与屈蹬技术的关系,以及踝关节技术对运动员途中跑中各项技术指标产生的影响。研究认为:背屈踝前摆腿技术要优于放松踝的前摆腿技术,主要表现在有利于屈蹬技术的形成,蹬地更有力,支撑时间更短,步频更快。

By contrasting the skill of sprinter＇s steady nmning, this article discusses the relation between the skill of ankle and bent -leged juggling, as well as the effect that the skill of ankle makes to the parameters. It can be shown that the skill of swinging leg with bent-backed ankle is better on bent-leged juggling than the other One with loose ankle, also an the time of supporting phase and the frequency of stride.
