中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,对世界男子100m纪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。 There are many theories about the division of the main track and field teaching materials in China on the periodic stages of running. Among them, there are still many differences between the cushioning of the land during the support period and the starting and stopping of the rear pedal. To solve this problem, the use of information technology-based approach to the world men’s 100m record holder Bolt’s technical parameters were analyzed. Proposed a new method of dividing the ground buffer and rear pedal, starting point and pointed out that the division should be concretely quantified in order to provide a theoretical basis for the practical application of sprint technical analysis.
