发帖数: 1733 | 1 短期的肌肉酸痛是因为乳酸堆积， 乳酸堆积是造成fatigue和muscle failure 的主要原因。 因为肌纤维在酸性环境下，收缩能力变低。但乳酸在八小时内就会被机体清除，所以事后酸痛并不是乳酸堆积引起。
大重量运动，会造成肌纤维轻微撕裂。大量的白细胞， 前列腺素和养分流到撕裂处试
图修复，造成修复性的肿胀和发炎，这才是酸痛的主要原因。
并没有证据证明酸痛后肌肉就会增长，但很可能是。因为肌肉只有在肌纤维撕裂后才能
生长。但work to failure 造成的酸痛对力量的增长并没有好处，因为你需要太长的时
间修复。而且起feed back 保护作用的golgi tendon 是有记忆的，你failure后golgi
tendon记住这个重量，下次就会把阈值调低，使你的中枢神经过早的发出放弃的指令，
反而会使力量降低。
运动前后用止痛药可以减轻酸痛。适量的cardio也会有帮助。workout 后的strech 对
有些人有效，对另外一些人没有。如果你酸痛时去做重量练习，做不到平常一半的量时
，就需要休息了。肌肉是在休息时，而不是在training时生长的。 |

你把痛点分的很细致，我再白话一下，你看对不对
1、膝盖骨上缘跟四头肌连接处疼，属于patellofemoral pain syndrome （PFPS /
runner's knee）
2、膝盖骨下边缘疼，也就是跟Patellar Tendon（髌骨韧带）连接处，这属于jumper
knee（中文称膝盖韧带炎）。
3、如果痛点再往下一个拇指宽度的地方，也就是Patellar Tendon下端，连接Tibial
Tubercle （胫骨结节）的地方，称为Osgood Schlatter disease （胫骨结节骨软骨病
？），常见于青少年。
照这么说，我感觉是第3类，也就是胫骨结节骨软骨病。不管怎么说，这几类病治疗和
恢复都差不多，看起来以后要增加举杠铃的训练项目，提高臀大肌和股四头肌的力量。
另外，问一下，这一个月，主要在游泳，每周3、4次，每次1-1.5小时，1500-2500码，
大部分蛙泳。不知道蛙泳频繁蹬踹是否对恢复有所影响

发帖数: 2112 | 30 最近做功课研究消除疼痛的办法，看到下面这边文章。大意似乎是：
1）炎症是身体对抗伤痛的自然反应，是身体自我修复过程的正常症状；
2）药物消除炎症，同时也抑制了身体的自我修复过程，反而不利于伤痛的恢复；
3）消炎药不能明显提高比赛成绩。
根据这篇文章的说法，我觉得ibuprofen或Advil最大的效果可能是止痛（类似麻醉剂，
消除或削弱大脑对疼痛的感受）。疼痛要求人不要过度使用身体；大脑不觉得疼了，就
会继续正常（其实是超量）使用身体。后果可能是短时间内保持了成绩，但加速了肌肉
