The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势；当身体重心垂线超过脚后跟后，在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大，原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动，主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩；在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆，在摆动腿下压着地后期表现出"小腿积极回摆"技术，对减小着地时的水平速度损失、加大向前用力都有积极影响；适当加大摆动下压着地阶段躯干的前倾角度，有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点；缩小后蹬结束后的后伸动作幅度，有利于减小腾空时间。

I believe you eye on the baby should be elimination of erythema, my son still has three days to one month before they are born then there is the white of the eye bloodshot ray, we are also worried that a very, very, slowly to eliminate its own , but any time you want to observe that a long time, then there should be a doctor; do not believe that the last leg wrappings, when there are many people warned us to puttee yo, how Otherwise how, alas, do not believe those words, unscientific, small Children up to 1 - 20 days longer腿就natural, it can be stretched, and then I fear that my son is also long a bandy legs, because he was sleeping on a two leg looks really a bit like it!!

相信你的宝宝眼帘上的红斑应该要消，宝宝还差3天就满月了，才生下来那时眼白有一缕血丝，当时我们也担心得不得了，慢慢的它自己就消掉了，不过你要随时观察到，久了还有的话应该找医生了；不要相信去绑腿，当时也有许多人告诫我们要绑腿哟，不然的话怎么怎么，唉，不要相信那些话，不科学，小宝宝长到1–20天后自然腿就变长了，也就可以伸直了，（当时我也害怕宝宝也长个罗圈腿，因为他睡觉时两个腿一盘上，看起来还真有点象也！！
