自由泳提高 CSS (Critical Swim Speed) 的高质量练习方法

很好的自由泳体会，值得探讨！

受益匪浅，先学习一下、提前改好自由泳姿势。

对游泳爱好者很有指导意义，毕竟大家不是为了竞技比赛来游泳，不要形成错位的自由泳概念

这个问题值得探讨。会继续关注

就是控制不住自己的身体       比方说其它人保持住超直动作要花三分力  有些人游自由泳就要花七分  比如就像拉韧带一个道理 有些人弯腰手碰到脚觉得很轻松  有些人就觉得痛死了要    还比如有些人在水里憋两分钟基本没问题，但是有些人一分钟就吃不消了  不过自由泳最重要的我感觉就是身体姿态了！

自由泳打腿要连续，就算把80%的注意力都放在腿上也是值得的。

Critical Swim Speed (or CSS) is a measure of your lactate threshold without the need for invasive testing and is a great estimation of your swimming speed over a distance of 1000 to 1500m.

By improving your CSS pace you will swim faster and more efficiently at any distance above 400m. As such, we regularly monitor this marker with 2-3 x yearly CSS tests which involve swimmers in the squad doing a 400m and 200m Time Trial with about 5 to 8 minutes rest between each.

The calculation plots a line of regression (drop-off) in pace between the two distances and has been used in sports literature since the early 90s as a simple way of testing for the intensity at which a swimmer's physiology suddenly starts to accrue a massive amount of lactic acid.

大家可以分析一下。

最近练习自由泳的体会，自由泳是不分什么交叉的，交叉只是入水点带来的视觉效果。一个基本的道理：从划水手离开水到这只手再次开始划水的时间，就应该是另一只手划水的时间。如果你滑行了，后果要么是整个动作周期中减速期的延长变成2面侧泳，要么是划水时间大幅缩短导致的仓促抹水。无论什么交叉，移臂手都应该比划水手快一点，这样才能保证有小幅度的动力重叠。划水比移臂还快的，一定进步还有很大的空间。

一切的一切都是由于身体姿态造成的
