                                 学习游泳的第二步是蹬边浮体,这个技术的要领是:人体自然放松,并做到三直,即身体直;腿直;双臂直。蹬边浮体可分成三个步骤:1,扶边团身,用一只手拉住池边,身体成侧卧,另一手前伸双腿收起,团身,将双脚掌平行触池壁,身体前倾。2,入水蹬边,先吸足气,将头部完全进入水中,松开扶池壁的手移到前面与另一手平行,双脚同时用力蹬边。3,滑行,蹬边后获得很快的初速度,人体在水中滑行,如果人放松平衡,可滑行5米以上,当气短需要吸气时停下,在浅水池可触池底站立,深水池则在靠近池壁或有水线的旁边练习,抬头吸气时拉住池壁或扶水线。

第二次游泳课的练习计划

1,复习游泳的呼气,头入水用嘴和鼻呼气,出水面就用嘴吸气,反复练习,占本课50%的时间,

2,蹬壁浮体,在回到池边时水中行走(浅池)或扶壁移动(深池),交替练习,蹬边练习占本课50%

一般的情况下,2-3次课程就可把这两个基本动作理解和掌握,但到学游泳技术时又会手忙脚乱,所以学游泳的特点就是要多下水以熟悉水性,增强水感,反复实践和体会,只要坚持,每个人都能成为游泳好手。

涛博士对我水中呼吸一文的点评有些道理,我用“水中呼吸”一词确实经不起推敲,用的是教练们口语和习惯用语,确切的是水中用嘴鼻呼气,嘴露出水面,马上用嘴吸气,上篇文章的标题恰当的词汇应该是“游泳的呼吸”,这就避免了概念上的混乱,谢谢涛博士。我也毫不怀疑在我们人类中到处卧虎藏龙,有些朋友还有特殊技能,更有身怀绝技者,应鼓励他们与大众分享他们的技能和特长。
