It is important to realize that the top range of race speed: minimization of resistances takes priority over increased propulsive force.

对于游泳速度而言，很重要的一点是：减少阻力要优先于增加推动力。

When watching Klim, one can see where there is an almost complete lack of propulsive force during armstroke recovery.

当观看克里姆游泳时，任何人都能看得出他在移臂期间几乎没有什么推进力。
