Frustratingly and despite their best intentions, good catch mechanics are very elusive for the vast majority of swimmers and triathletes. A good catch on the water is one of the things that separate elite and advanced swimmers from the masses and allow them to move quickly and efficiently through the water - but why do so many swimmers struggle to improve their catch?
尽管经过刻苦的尝试，但是好的抓水对大部分人来说还是很困难。好的抓水是优秀的游泳选手和普通选手的显著区别，但为什么普通人无法提高他们的抓水呢?
Let's take a look at a common problem that might be holding you back. Here is a typical sequence from one such swimmer Anna showing her entering the water and extending forward:
让我们看看一个普遍的毛病，以下是Anna的入水图片：

In the final position (3) her elbow has dropped down lower than the wrist with the hand facing forward. This is a problem because from there it is impossible to initiate a high-elbow catch on the water. Instead Anna starts to pull through with the elbow dropped losing her a lot of propulsion:

The interesting thing here is that Anna knows she should not be dropping her elbow in position 3 and yet is unable to stop it happening. Why? Because she is trying to keep her hand too near the surface at this point in the stroke and despite her best intentions, as she rotates her body onto her left side she has to drop her elbow to keep it near the surface. In comparison, take a look at Australian elite swimmer Rhys Mainstone:

Comparing 3 and 5, notice that Rhys' hand is deeper in the water, which allows him to keep his elbow higher than the wrist and the wrist higher than the fingertips. He can then bend his elbow and start pressing water backward effectively (6), generating good propulsion.
As you swim, try entering the water and extending forward slightly deeper so that you are able to keep your elbow high. Experiment with different depths to see what feels best - somewhere between 20 and 30 cm (8 and 12 inches) is best, the exact depth will depend on how broad you are and the level of flexibility in your upper back and shoulders. Of course you don't want to go too deep as this will send your hand down towards the bottom of the pool, it's a matter of finding the sweet spot between the two
在你游泳的时候，尝试入水深一些，这样你就能够让你的肘部保持在较高的位置。尝试不同的深度，看哪种最舒服，20-30cm也许最好，准确地深度要根据你的宽度和身体的柔韧性。当然也不用太深，那会让你的手部指向池底，要在中间找到甜点的位置 作者: swimsmooth 时间: 2012-6-17 00:21
A quick warning here: As you improve your catch you may feel your stroke rhythm lifting and your catch and pull through feels 'too easy'. These are good signs that you are getting things right - don't be put off! Whenever you are making changes to your stroke be objective and monitor how fast you are swimming versus your level of effort, don't just use your judgement of what feels immediately right and wrong, doing so can be very misleading at times.
