• By 王川栋 说, 2月 17, 2010 Perpendicular PullIn this clip, watch Aaron’s hands. Notice that the palms of his hands are always open and they are always pushing water toward his feet.First, look at that closer, the hands and the palms open, creating a big surface or paddle for pushing water. When Aaron thinks about his pull, he thinks about creating maximum surface area. He wants to keep his hand opens and push water all the way from the catch until the final downstream. Notice when the palm is open, the fingertips point toward the laid line, and the hand perfectly perpendicular toward the body. By maintaining this angle, Aaron pushes water not only with his palm, but also with his forearm. To create an even bigger surface area, Aaron also uses his elbows. In this clip, watch how he maintains a high elbow, instead of letting his elbow collapse during the pull, Aaron actually pushes the elbow up toward the hand at the beginning of the pull. By keeping a high elbow, he gets a faster pull and more control of his hand position from the entry all the way through to the final downstream.Here you can see it again, Aaron creates a long pulling surface with his hand and forearm. He pushes the elbow up, passes the head toward the hand. It’s all about creating and maintaining surface area and keeping the hand and forearm perpendicular to the body. At race pace, it is harder to see the position of the hand. But if we watch from underwater, you can see how Aaron uses his hands, forearms and elbows to create maximum surface area for the pull. 感谢学姐！the final downstream和surface area怎么理解呢？

• By 蔓陀罗 说, 2月 17, 2010 你学仰泳啊？不用翻译吧？这段是：Most swimmers think that it is important to have big kick and fast kick for back stroke, but for Erin, the most important thing is to have steady and constant kick, and this is something he works on everyday. Erin tries to keep his kick in harmony with the pull. When his swimming is slow and easy, his kicks and pull are balanced, and noticed that his kicks are constant, not stop and go. Has he picked the pace, Erin are more (missing words in the video) to keep them in balance. In the race pace, the balance is still there. The kick doesn’t overpower the arms, and the kick is constant. Erin tries to kick from hips, and keeps the legs fairly straight. Erin uses the big muscles in the hips and thighs to generate power. Another thing that Erin tries to do is sway one leg over the other as he slides the hips, this helps to initiate the pull and wall smoothly from side to side.Here is another angle where you can see the sway of the legs, one over the other. Let us slow them down and see the timing of sway with the push of the hips and the start of the pull. Notice that the kicks are constant and of course, don’t forget to point your toes.In this clip, watch Erin’s hands, notice his palms always open, and they are always pushing the water towards his feet. Let us look that closer: the hand enters, and palm is open, create a big surface of paddle for pushing water. When Erin thinks of his pull, he thinks of creating the maximum surface area, he wants to keep his hand open instead of keeping his hand close all the way from his cap until the final down sway.Notice that when the palms are open, the finger tips are pointing towards the lien line and the hands are perpendicular to the body. By maintaining this angle, Erin pushes the water not only with his palm but also with his forearm. To create even bigger surface area, Erin also uses his elbows. In this clip, watch how he maintains high elbow. Instead of letting the elbows collapse during the pull, Erin actually pushes his elbow up towards his hand at the beginning of the pull. By keeping his high elbow, he gets fast pull, and more control over his hand position from the entry all the way through the final down sway. Here you can see it again, Erin creates a long pulling surface area with his palm and forearm, and pushes the elbow up past the head and toward the hand.It is all about maintaining and creating the maximum surface area, and keeping the hand and forearm perpendicular to the body. In a race pace, it is harder to see the position of the hands. But if you watch from under the water, you can see how Erin uses his hand, forearm and elbow to create maximum surface area for the pull.
