触壁前呼出所有的空气是很重要的,这样转身时就可以快速吸进一口气。一转回身,脚离开墙,立即开始打海豚腿,转身后就可以获得最快的速度,并为出水划臂制造动力。Michael的出水划臂动作刚好在水面完成,当他第一次移臂时,身体的线条几乎与水面平行。这一技术把迎面阻力减为最小,最大限度地把(转身阶段的)能量转换到了比赛中的游泳阶段。
(It is important that all of swimmer's air be exhaled by ready for? touching the wall, so that a quick breath may be taken during the turn. Once the turn is made, the feet shall leave the wall and immediately begin the body dolphin technique. This will allow for maximum speed of the turn and generate momentum for the important breakout stroke. Michael takes his breakout stroke just at the surface, so that his body line is horizontal when he makes the first movement with his arms. This technique minimizes frontal resistance and allows for maximum transfer of power into the swimming portion of the race. )
