ONe of hte things the speed suits did was help the swimmers maintain posture, in spite of fatigue...drag reduction, not from friction, but from form.
Now that the speed suits are no longer allowed, top level swim coaches have been focusing much, much more on core strength and maintaining firm body posture at the end of a race...not on pulling harder.

鲨鱼皮泳衣的一大作用就是能让选手在疲劳的状态下仍能保持身体姿势,从而减少阻力,而不仅仅是减少摩擦力。
现在不让用了,顶尖教练于是把注意力更多地放在核心力量和如何在比赛的末尾仍能很好的保持身体姿势,而不是如何划得更有力。 |
