然后浮上来。
and then come up.
好了,预备,铅笔。
All right, all right. Ready, pencil.
做这个练习的目的是让大家
This drill is meant to have people
适应把气吐净后的感觉。
be comfortable completely exhaling.
“沉底”。
"sink it".
好极了。
That was wonderful.
你这个小家伙完成的很好。
You guy did a great,great job of that.
你们知道,我曾经指导过奥运会选手。
You know that I have coached Olypians.
他们不肯沉到池底,
They won't sink to the bottom or the pool.
他们不肯沉到池底,
They won't sink to the bottom or the pool.
他们不肯把气吐净,
They won't let all their air out,
因为他们害怕把气吐净。
because they are afraid to let all their air out.
结果他们在做自由泳换气动作时,
So when they breathe and swimming freestyle,
头就长时间歪向一边。
they hold their head to the side,
这是因为嘴巴出水后,他们既要吐气,又要吸气。
because they are exhaling and inhaling
with their mouth out of the water.
正确动作是:嘴在水下时吐气,
You want to exhale when your
mouth is in the water.
嘴一出水就立即吸气,
And you want to inhale as soon
as your mouth clears the water.
这样头就不用长时间转向一边了。
So you don't have to have your head
turn to the side very long at all.
但是,除非你在水下时把气吐净,
But unless you completely exhale
with your mouth in the water,
否则头转到一边时,
你还没做好吸气的准备呢!
you are not ready to breathe when
you turn your head to the side.
好了,让我们再把这个练习做一遍。
OK, let us try that one more time.
