对短跑途中跑支撑过程时相阶段的划分是正确认识百米途中跑缓冲技术的基础,支撑阶段划分为三个时相对研究最大速度的影响因素有重要作用。现在采用高速摄影设备使过去对单步技术的研究从传统的运动学参数发展到现在的运动生物力学层次,体现在由原来的对步长步频的研究到现在的对膝关节踝关节着地角度的研究。论证了减少前蹬冲量的关键技术,指出了膝踝两关节在缓冲中的重要作用。
The division of phase phases in running support during sprint is the basis for correctly understanding the running buffer technique in the middle of a hundred meters. Dividing the support phases into three factors plays an important role in the relative factors influencing the maximum velocity. Now the use of high-speed photographic equipment so that the previous study of single-step technology from the traditional kinematics parameters developed to the current level of sports biomechanics, reflected in the original steps on the pace of research to the current knee ankle ground angle Research. The key technology of reducing the amount of front pedal stroke is demonstrated, and the important role of knee-ankle joint in cushioning is pointed out.
