为什么我自由泳总是很费力

我认为是你的姿势不对,或者说是你的动作不协调。应在双臂划水时,双脚上下摆动。这样不只能省劲,还能提高速度。

自由泳
游泳是全身运动,任何一个部位的活动都离不开全身的协调配合。从表面上看,自由泳依靠划水和打腿产生推进力,实际上,躯干的作用也不能忽视。首先,躯干 应保持一定的紧张度,腰部如果松软,整个人就像一摊泥一样。其次,身体的转动能够有效地发挥躯干部大肌肉群的力量,减少阻力,提高工作效果。
自由泳的完整配合有多种形式。一般常见的是每划水2次,打水6次,呼吸1次。 '

1、手的入水点在肩的延长线和身体中线之间,以大拇指领先,斜插入水。
2、入水后,手、肘、肩继续前伸,使手臂伸展。随着身体的转动,屈腕、屈肘,手臂向 外、后方抓水;手下划到最低点后,旋转手臂向内、上、后方划水,保持高肘屈臂的划水姿势。
3、手臂与水平面垂直时,经手领先,加速推水,手臂转为向外、向 上和身后划水直到大腿侧,提肘出水。
4、出水后,手臂自然、放松地经空中向前移臂,保持高肘姿势。然后手在肩前领先入水,开始下一个动作。 '

1、手臂在水下成曲线划水路线,从侧面看,手相对于身体的划水轨迹为“S”形。
2、自由泳两臂配合有前交叉配合、中交叉配合、和后交叉配合3种基本形式。本图为前交叉形式,为初学者比较容易掌握的方式。
'

单臂打水划臂动作是初学者应该重点练习的动作。如此图,左臂划水,那么可以右臂扶板。一般腿打水10产次左右,手臂划水一次。掌握到一定程度的时候可以加上呼吸练习。具体组数以及练习方法,我们会在教学中详细介绍。
腿部鞭状打水:
1、打腿动作从髋部开始发力,大腿带动小腿,做鞭状打水动作。
2、向 上打水腿从直到弯。以直腿开始向上打,脚接近水面时屈膝,小腿上抬,使脚牚露出水面后向下打水。开始可直腿打水,但腿略放松,不要僵硬,在水的压力下腿会 自然弯曲。向下打水前膝关节弯曲角度约130-160度,打水幅度约为30-40厘米。打水时要绷脚(芭蕾脚),不要勾脚。

回答2:

原因很简单,是因为你的头伸出来,影响身体位置,上半身被头带的太高了,下半身控制不好,向下沉,这样很费力。其实你是姿势不对,不是力量问题,你其实只要学会换气就好,自由泳的换气是头放平,左右两边换气,不是抬头换气。

回答3:

肯定是姿势不对,自由泳在游的时候面部是朝下的,完全不能呼吸,只有在换气的时候脸才扬起来。可以单边换气也可以双边换气。

回答4:

我也是刚从自由泳出来的。刚开始练肯定这样,很费体力,坚持练下去,你会发现游上几百米都没事.
主要还是熟练度的问题。

回答5:

平时用自由泳 游太少了而已,游多了把握好姿势就会好点了
