在短跑途中跑中，脚着地后髋关节并未弯曲，而是继续伸展：踝、膝关节是被动弯曲，而不是主动弯曲。此刻主动支撑会缩短制动时间，有利于制动冲量的减小。着地缓冲动作的细致划分，对全面正确地认识跑的原理是必要的，着地缓冲阶段应包括前蹬和后蹬的前一部分(垂直部位至最大缓冲)。摆动腿下压动作的作用有重要意义，应引起足够重视，在跑的划分中应有明确的界定。

In dash running, the hind-hip joint does not bend, but continually stretch, ankle joint and knee joint does not bend actively but passively when leg lands. Thrusting against the ground actively can shorten the braking time and help decrease braking impulse, it is necessary for understanding the runing principle to divide carefully the cushioning action of landing, the cushioning action of landing include fore-thrusting and hind- thrusting, we should devote much attention to the leg thrust, it is important to define the leg thrust explicitly.
