骑撑前回环是单杠的一个较简单动作,但要做好这一动作,不是很容易的。学生在做单杠骑撑前回环时,由于怕从杠上跌下,双手死死握住单杠,骑撑杠上的两腿没有分开(两腿前后分开一般为120°左右),而夹得很紧,弓腰,驼背向下用力,这样就造成回环时的半径减小,速度减慢,掉下杠来。如何才能做好骑撑前回环这一动作?根据骑撑前回环的动作结构特点和力学原理,完成该动作必须获得足够的翻转力量和回环半径速度,骑撑杠上(以右腿在前为例),两手反握单杠,直 Riding the front loop is a simple horizontal bar action, but to do this action is not very easy. Students doing horizontal bar riding support before the loop, due to fear of falling from the bar, hands tightly holding the horizontal bar, riding on the bars of the legs are not separated (before and after the legs apart generally 120 ° or so), and the folder is very Tight, bow waist, hump back downward force, thus reducing the radius of the loop when reduced, slow down, fall off the bar. How can we do a good job before riding back loop this action? According to riding the back of the ring before the action of the structural features and mechanics, to complete the action must be sufficient flip force and the radius of the back ring, riding on the bar (with the right leg in front of Example), both hands anti-grip horizontal bar, straight
