试论跑的支撑时期着地缓冲与后蹬阶段的止、起点的划分

New Check Point Method of Supporting Landing Buffering and Pedaling Backward in Run Support Period

我国主要田径教材关于跑的周期阶段的划分存在着多种理论,其中对支撑时期着地缓冲与后蹬起、止点的划分也存在较大分歧.为解决该问题,运用信息技术为主的方法,对当今世界男子100 m记录保持者博尔特的有关技术参数进行分析,提出了着地缓冲与后蹬止、起点的新划分方法,指出划分应具体量化,以期为短跑技术分析的实际运用提供理论依据.

Our main track and field theory about running cycle stages exist various theories of division and the check point of landing buffer and stamped in support period also have division.In order to solve this problem,we used the method of information technology to analysis the men＇s 100m world record holder boulde＇s relevant technical parameters.Put forward with the new check point method of supporting landing buffering and pedaling backward,It is pointed that the method should be quantified into specific for the practical application of sprint technical analysis providing theory basis.
