lactic acid built in your muscles and your muscles won't feel sore. |

下周就忙了。
一般酸疼出现在练后24-72小时。一般持续两到三天，比较流行的说法是乳酸的堆积引
起的。实际上医学界占主流的说法是与乳酸无关。乳酸(实际上是lactate, 虽然大家都
说lactic acid)在血液和肌肉中的水平一般在运动后30-60分钟就恢复到正常值。而酸
疼一般是24小时后才出现。
那么是什么引起的肌肉酸疼呢？医学界有几种理论，一种说法是肌肉细胞的损伤，另外
一种说法是肌肉在锻炼后生长新的肌节。现在还没有定论，是运动医学中的一个研究前
沿。
从训练的角度来看，那种eccentric contraction是引起酸痛的原因。eccentric
contraction是指肌肉努力收缩，但依然被拉长的contraction.
如何避免捏，充足的热身，逐减提高强度会有帮助；基本上没有药物可以帮助；结束后
的伸展活动和按摩能不能帮助现在还有一些争议，虽然这些可以有别的好处，比如促进 |

小弟本来想问问有什么办法让肌肉不酸痛那么久的办法。因为刚开始练习，书上说一周
三次。可是昨天练完后肌肉一直酸痛。想着明天要是还这么酸痛可怎么办。后来及时找
到了书上的解决办法：锻炼后拉伸。书是Gunnar Peterson的 The workout.
书上把锻炼后的拉伸比喻为做完饭后的收拾(clean up)。我觉得挺有用的，就在这里重
复一下，可能精华区里也有。但是：重复表示强调嘛。“当拉伸肌肉时，那部分肌肉的
血液流量就会变大，带来了大量的氧气。氧气不但能使肌肉保持更长的活动时间，还能
帮助排除过量的乳酸(lactic acid)，从而减少第二天的肌肉酸痛。”
先说点题外话。这学期系里的讲座请来了一个在美国工作多年的中国人。他说，他的书
本知识都是从国内学到的，可是如何运用，思考的方式是从美国的工作中慢慢学到的。
这个拉伸动作在国内也学过不少。可是我发现照着peterson书上的动作做了之后，有很
明显的效果。部分肌肉酸痛减轻了，而且有一种凉飕飕像薄荷那种感觉，很舒服。
好了，先写到这儿。看火箭奔23连胜了。如果 |

easy to be gone, after a sleep or a hot tube. 一般, 一俩天会好.
如果引起 by muscle fiber breaking. For slight muscle fiber breaking, which
typically happens in weight training and lasts for several days, it should
be ok. 但是 you need be careful as well.

Someone told me the logic is
ATP up -> hydrogen ions up -> too much and exceeds the threshold ->
trigger fatigue -> slow down ATP production
I am not sure of the part, "lactic acid does inhibit muscle
contraction."
I guess the argument might be, you feel sore muscle and fatigue because
hydrogen ions are generated too much and they are more than your body
can
handle. Meanwhile, this decreases your muscle pH too .
Therefore, it might be because of ATP inducing the sore musc |
