我经常看到泳者练习他们的划手滑行长度，有些是让人印象深刻的低划数游泳（譬如说划手12次游25码）但是非常没有效率的游泳技巧。

I've often seen swimmers who have been working on their Stroke Length, swimming with an impressively low SPL – let's say 12 strokes for 25 yards – but a thoroughly inefficient style.

我的2009年秋季充满了瑜伽、慢跑和恢复游泳练习——从一次游300码逐渐递增到500、800码。

My 2009 Fall season was filled with yoga, gentle runs, and working my way back into swimming—300, 500, and 800 yards at a time.

球道总长度为1000码，球道虽短，却为球友提供了一个练习短杆和推杆的机会。

The fairway is totally 1000 yards long, affording a good chance for short short game and putting .
