Outside-In Kick (听写版) 蝶泳 --- 由外向内的打腿

BUTTERFLY - Outside-In Kick (听写版)
It's funny how we discover new things in swimming. Sometimes, when you're looking at one thing, you discover something else. Just goes to show that we should always keep an open mind on EVERYTHING in swimming.
These observations are driven by last week's Drill of the Week, and the comments about the swimmer's kick. In the drill, the swimmer was working on her underwater dolphins. Someone commented that it seemed like her knees were a bit of too far apart. In this week's drill, we'll illustrate a few different athletes who kick in a similar fashion.
Why Do It:
Practicing this drill could give you a new dimension in your dolphin kick. Who knows... if you've always had trouble moving forward with your dolphin kick, maybe you're not making the right connection with the water and this little trick can help. For others, this may not work at all. Is it right? Only YOU can tell.
How To Do It:
1. This is a tough one to explain, so rather than go through step-by-step instructions, we'll show you some examples. While you're watching, imagine you're going to kick from outside IN during your dolphin kick. Rather than kick up and down, try to snap your feet down and inward. Just as a sweeping hand motion in freestyle (like the "S" pattern) can help you grab more water, this inward-moving kick can help you grab a bit more water during the path to the finish of the kick.
Let's check out some other swimmers who perform this type of motion.
The first swimmer is Olympic gold medalist Misty Hyman, and this footage is from her Go Swim Butterfly video. Notice that her legs separate and that the feet sweep IN slightly on each kick. The faster she goes, the less time there is to complete this move... but it's in there.
The next swimmer is 4-time Olympic medalist Kaitlin Sandeno, with footage from her Go Swim All Strokes video. Kaitlin also has a tendency to sweep her feet IN on the kick. Again, during whole-stroke swimming, the motion is not quite so evident, but it's there.
Next, let's check out a great swimmer who's using ONLY his legs. This footage shows Kevin Clements doing a kicking drill. From the side, you can see it's basic dolphin kick... but as Kevin rotates his body toward the camera, you'll notice the distinct outside-in motion of his legs.
Finally, let's take another look at our swimmer from last week's drill. Notice that when she's swimming -- rather than just working on her underwater dolphins -- her legs don't make such a pronounced, inward motion. Instead, they incorporate that move in a more narrow, more efficient manner.
There are many lessons we can take from this. One... is that when one part of the body is taking SOLE responsibility for propulsion, the actions frequently become LARGER. Two... is that if we can identify the productive things we do when we isolate a particular move, maybe we should try to incorporate a bit MORE of that into our whole-stroke swimming. And three... that we should not restrict our natural motions when we experiment and search for faster ways to swim.

蝶泳 --- 由外向内的打腿
我们在游泳时常常发现新东西，而这些新东西的发现方式时常很有趣。有时候，当我们着眼于某件事时，却发现了另一件事。这恰好说明，我们在游泳时应该抱着虚心态度，留心周围的每一件事。
上述随感是由上周的练习（BUTTERFLY - Lower-Back Dolphin Kick腰部参与的海豚式打腿）以及大家对其中示范者的评论激发的。在那个练习中，示范者在演示水下海豚式打腿。有些人评论说，她的膝部似乎离得太远了。在这周的练习中，我们将列举几个运动员，他们也采取了类似的打腿方式。
为什么做这项练习：
做这项练习可以使你从一个全新的角度体会海豚式打腿。谁知道呢？……如果你在做海豚式打腿时，总是不往前走，这也许是因为你没有掌握好人与水的关系。这个小窍门也许对你有效，但对其他人可能无效。我做得对吗？对不对只有你知道。
如何做这项练习：
这项练习很难解释，因此我们不再逐条说明，而是给大家举几个例子。在你观看视频过程中，请想象一下，你正在从外向内做海豚式打腿。不要上下打腿，而是尝试同时向下向内打腿。就像你游自由泳时，手的内扫动作（划一个S形）使你抓住更多的水一样，这个向内的打腿动作能使你在结束打腿之前抓到更多的水。
让我们再来观察另外几个这样打腿的运动员。
第一位是奥运会金牌得主米斯蒂•海曼，这段视频来自她的《同我一起游蝶泳》。请注意，在每次打腿时，她的两腿分开，两脚稍微向里扫。她游得越快，做这个动作的时间越少，……但仍能看出这个动作。
下一位是获得四块奥运会奖牌的选手凯特琳•桑蒂诺，这段视频来自她的《和我一起游四种泳姿》。凯特琳在打腿时也趋向于两脚内扫。不过在做配合游时，这个动作就不明显了，但仍然存在。
接着让我们再观看一名优秀的选手，他只用两腿做动作。这段视频显示凯文•克莱门特正在做打腿练习。从侧面看，这不过是一个基本的海豚式打腿，……但当凯文转过身来，面对镜头时，你将注意到，他的两腿从外向内的动作非常明显。
最后，让我们再看一遍上周游泳视频中的示范者。注意：在她游泳过程中，而不是在她做水下海豚式打腿时，她的两腿并没有做出明显的向内的动作，而是以一种更窄、更高效的方式来应用这种打腿方式。
我们从这个视频中可以学习许多东西。第一，当推动力单独由身体的某一部位承担时，做出的动作通常比较大；第二，当我们做分解练习时，如果我们能识别出有效的动作，那么在进行配合游时，我们就应该更多地采用这样的动作；第三，在我们尝试并寻找游得更快的方法时，我们不应该约束自己自然的动作。

希望五一.在加密方面更进一步.防止一些小人盗链!
