当进行蝶泳转身时,注意几个关键要素。第一点是游泳者必须加速游向池壁。这会允许转身中最大的能量转换。当Michael靠近墙时,他加速,双手指尖触壁。紧接着,他开始转身,曲膝团身同时转头。上方手臂经空中从头上回挥,下方手臂直接置于耳下。整个转身在一个动作里完成.
(When performing the butterfly turn, pay attention to several key aspects. No 1, the swimmer must be accelerating into the wall. This will allow for maximum transfer energy in the change of direction. As Michael approaches to wall, he builds speed, and hit the touch pad with both hands at finger tips. Immediately, he initiates the change of direction by pulling his knees to his chest, throw his head straight back, and have his lead arm pull back and down to the bottom. The trail arm is placed directly below his ear. And the turn is performed in one movement. )
