Breaststroke_Don’t Pull Harder蛙泳_不是用力划就可以

學習蛙泳正確手部動作,可以幫助你建立一個更有效率,有節奏的蛙泳技術。

最好的蛙泳是在每一動作循環使用你的身體來驅動前衝,良好的划手讓你的身體有可能做到,不用說你也知道,當然還需踢腿配合。 划手是蛙泳動作循環中的一個組成部分,但它並非推進的主要動力,划用力一點或試圖划更多的水,實際上可能是適得其反。

雖然蛙泳划手並非主要驅動力,不決定蛙泳的速度,但做的不合節奏,只會事倍功半成為老鼠屎,白白浪費了用力踢的腿力,它對蛙泳設定整個動作循環非常重要。

Breaststroke Phases

Breaststroke Phases – To Swim Breaststroke Faster, Don’t Pull Harder


Excerpt & photo from :USA Swimming, by Russel Mark(High Performance Consultant)

The best breaststroke is about using your body to drive/surge forward with each stroke, and having a pull that allows your body to do that. The pull is an integral part of the stroke, but it is not the primary driving force of propulsion in breaststroke. Pulling harder or trying to pull more water can actually be counterproductive.

The breaststroke arm pull doesn’t determine breaststroke speed. If it did, the best breaststrokers would be pulling faster or pulling further back when swimming faster.

We looked at the technique of Brendan Hansen, Kosuke Kitajima, Leisel Jones and Rebecca Soni. These four breaststrokers are unique in that they are equally successful in the 100m and 200m event. The speed and technique of the pull remained exactly the same, regardless of swimming at a faster speed (100m) or slower speed (200m). From the start of the pull to the finish, the 100m and 200m videos remained in total sync. The differences were:

  1. The kick was quicker in the faster speed. Faster heel speed to set up the kick. The start of the kick remained the same, but the heels were brought up faster and then the backward kick started sooner.
  2. Less glide in the faster speed. Less time in between strokes.

Nonetheless, the pull is critically important for setting up the entire stroke. Here is what’s important about the breaststroke pull:

  1. Start the pull by sculling outward, with the palms facing the side of the pool. It’s not like freestyle, backstroke, or butterfly where you want to catch a lot of water in the first part of the pull. The outward scull holds a good body position and sets up the rest of the stroke to be the best possible.
  2. The arms never push water directly backward. After the scull, the hands should make the shape of an upside-down heart – rounded on the outside and then coming together as they extend forward. (See illustration, above).
  3. The further back your hands go, the harder it is to shoot them forward. It’s ok if your elbows come next to your body, but keep your hands in front of your chest. You won’t feel like you’re pulling as much water as you can, but your stroke will be better in the end because you can shoot your hands and body forward better.
  4. Bring your hands together as they extend forward. Use your elbows to push your hands forward, but don’t squeeze your elbows together. At the same time, press your chest and face forward to get your body driving forward.

One final note: All of the best 100 breaststrokers increase their tempo as they swim the final length. They are able to do this because they are able to shoot their body and their hands forward very effectively. That’s what you should be focused on as well.
