We lose speed, but we should gain in strength and size.

But a swimmer is neither like a racing shell ( single, double scull, or whatever) nor a yacht. The rower lose their rhythm and the boat lose speed.

但游泳运动员并不是赛艇，他们没有赛艇（无论是单桨，双桨还是其他的什么桨）那样的艇身。桨手们划桨的节奏乱了，赛艇因此慢了下来。

Note: The Plane may lose speed if the pull is not enough.
