很多教练提到蝶泳的波动是短轴的
不过,我不喜欢这个词
因为我不想你的身体飞得很高

你要尽量保持身体接近水平,减少阻力
所以我们教的方式是
试着避免抬高你的肩膀来呼吸
用你脖子上的肌肉代替肩膀的肌肉来换气
实际上一个动作,你几乎可以从颈部完全伸展到这里
到了手下来时,脖子几乎完全弯曲了下来。
所以你需要从一个极端走向另一个极端

但我们教的方式就是蝶泳滑行练习
所以你推水后,在水面上滑行
用你的脖子保持低,保持肩膀向下。然后你就停在这里
这是我们六岁时第一次学会蝶泳的方式
我们没有力气把胳膊拿回来

所以我们停下来,然后我们低头,然后我们再移臂
这里的目的是要平行水面,在上面滑行
蝶泳可以产生四种泳姿中最快的速度。

可能达到三米每秒
奥运冠军Roland Schoeman示范
如何在蝶泳周期中同时推动双臂,加上第一次踢腿,产生巨大的力量
将他提升到水中并推动他前进
由于速度和正面阻力之间的指数关系
在这个关键时刻波动和保持水平的身体姿势是很重要的
这个练习鼓励罗兰用他的脖子而不是肩膀来做举臂
从一个完整的颈部延伸,到完成呼吸
在手臂复原时,他的下巴往下掉,几乎碰到胸部
如果你踢腿不强,试试戴着脚蹼练习
要懂得保持肩部放松,抬高颈部呼吸的重要性

我们不仅在这个水平位置会更快,
但你会发现做蝶泳变得容易

A lot of coaches referred a butterfly rolling is a short-axis.
Though, I hate that term because you really don't wanna rotate the body up and fly.
You want to keep the body pretty close to horizontal as much as you can, and reduce drag.
And so the way we teach that is
by trying to avoid elevating your shoulders for the breath,
coming up using your neck muscles instead of your shoulder muscles to get the air.
It's actually one stroke,
where you almost go from a full extension of the neck here,
to when the hands come down, to almost a complete flexion of the neck down.
So you're going from almost one extreme to the other.
But the way we teach that is, what we call, the butterfly skate drill.
And so you're gonna actually pull, skate over the water,
using your neck staying low, keeping the shoulders down.
And then you're gonna stop here.
This is kind of the way we swam butterfly when we first learned when we're six years old.
We didn't have the strength to get arms back. So we stop, then we drop the head, and then we come over.
over.
The purpose here is to get low to the water, skate over the top, but not come up like this, okay.
The butterfly can produce the greatest speed of all four strokes,
potentially reaching over three meters per second, or nearly seven miles per hour.
Olympic champion  Roland Schoeman demonstrates,
how the simultaneous pull of both arms, plus the first of two hard down kicks in the stroke cycle
produce a tremendous force, lifting him higher in the water and propelling him forward.
Because of the exponential relationship between speed and frontal drag,
it's important to roll and keep a horizontal body position during this critical moment,
almost as if you were skating over the top of the water.
This drill encourages Roland to use his neck rather than his shoulders to do the heavy lifting.
Going from a full neck extension as he breathes,
to his chin dropping down to nearly touch his chest during the arm recovery
If your kick isn't as strong,
then try this drill with fins on,
to appreciate the importance of keeping the shoulders down, and elevating the neck for the breath.
Not only we assume faster in this horizontal position,
but you'll find doing the butterfly become earier.

“头颈以下全是腿”,胸部发力是正确的。是身体带动手臂,而不是 身体跟着手臂走

总结长蝶不累的方法:
1要悠着劲飘蝶;
2,少用双臂的力量;
3、利用身体波浪起伏去蝶;
4、为了省力,不要蝶很高
再总结一下,就是要学会省力!省力!!

除非专用泳道。否则神憎鬼厌。专业队通常都不允许这个游法,同时也不会只游个1千。业余的说,大波浪,大角度脚腰用力,连续1千不是搞玩的。市民级别,蝶500至1000,慢点,小波浪,手部动作也许看起来丑点,关键能舒展双臂,好了。

年岁大了,蝶泳对身体没大的好处,特别是长距离,同时,大波浪对腰脚用的力量也较大,不太合适中老年人。所以我最后说了,慢点,动作看起来丑点,关键能舒展双臂。

从技术交流上讲,贴主用过这个方法蝶1000吗

蝶泳比较费腰力,年岁大了,蝶泳对身体没大的好处,特别是长距离
要悠着劲飘蝶;少用双臂的力量;利用身体波浪起伏去蝶;不要碟很高,这样会省点力气

头部的高度每降低一厘米都会省下很大力气。
