公开水域如何正确地观察前方和换气(系列图解)
公开水域观察水面前方时的正确动作应如下图:
(保持你的头部在较低的位置,仅仅只需把头部抬到让你的眼睛在水面之上就足够了)

很多泳者常范的错误是抬头出水,并试图在前看的同时换气,这将让腿下沉,增加拖曳阻力,从而破坏你的划水节奏。

紧接抬头动作之后马上侧转换气,其连续动作如下列图示:

As you catch the water and pull through with your lead arm, lift your head and look forward. Then immediately rotate to the side to breathe with the stroke, dropping your head back into the water as you rotate. The whole thing is one smooth fluid action and it takes less than a second to complete.

整个过程应该是一个相当平顺的行为,完成这个动作花费的时间不到一秒)

Practise this technique in the pool and get used to timing your head movement. It's normal for it to feel quite mechanical and awkward at first so allow yourself around six sessions  and it will start to feel much more natural.

Turn A Fuzzy Picture Into A Clear One

The great thing about this technique is that it creates less downward pressure on the legs and so less drag, there's also very little interruption to your stroke rhythm. The downside is that you don't have very long looking forward, so hold the image of what you saw in your mind and analyse it afterwards. With any sighting technique you won't always get a clear view of what's ahead but that's OK - don't panic! Perform a couple more strokes and sight again and you'll gradually turn a fuzzy picture into a clear one in your mind.

How Often Should You Sight?  应该多久看一次?

Anywhere between every 3 and 12 strokes depending on the conditions and also on the symmetry of your stroke. If you have confidence that you swim straight then you can afford to look forwards less frequently, avoiding the extra effort of lifting your head and the downward pressure on your legs that results.

If you find you veer off course all the time then something as simple as bilateral breathing  during your training can significantly improve your stroke symmetry, helping you to swim straighter and faster in open water as a result.
