By Randy Hall | May 15, 2013 | 22:50
It's easy to tell that President Obama is going through a scandal-ridden “
tough time” since he's even under fire from Jon Stewart, host of “The
Daily Show” on the Comedy Central cable channel, who said on Tuesday that
the Democratic occupant of the White House “can't keep saying you found out
about news at the same time as us!”
The liberal comedian said he found it strange that the pres... 阅读全帖 |

以加深理解. 如果有同学提供他,她, 它的数据,可以作为样本来设计锻炼.
上堂课讲了aerobic intensity的测算, 因为aerobic 本身就是非常大的题目, 所以很
多东西仅仅是浅尝辄止.入果有同学感兴趣, 可以在以后的课程中加深.
anaerobic: 就是对家看到肌肉男,(可以去做苦力).
通常有两类测试方法, RM 和 功能测试.
RM (repetition maximal ) 指最大的肌肉力量. 1RM 就是一次能举的最大量(举不动第
二下), 2RM 举两次, 以次类推.所以16RM 要远小余1RM.
这个概念使用于所有骨骼肌肉.
1RM特点, 精确, 缺点, 危险, 难于控制.
临床多用predictive RM. 就是测试10-16 RM , 然后换算成1RM, 见下表.

发帖数: 2679 | 18 有氧运动（aerobic)和无氧运动（anaerobic)分别指在细胞的能量代谢过程中
是否有氧气参与。顾名思义，有氧气参与就是有氧运动，反之就是无氧运动。
身体的能量代谢就是把摄入食物中的化学能转换成运动时肌肉压缩扩张所需要的生物能
的过程。
大部分人体细胞更喜欢有氧代谢，因其能量代谢过程直接高效。有氧运动时，只要还有
能源储备和充足的氧气，肌肉细胞几乎会不知疲倦的压缩扩张。
当运动强度增大，对能量的需求超过了有氧代谢所能提供的能量时，无氧运动就发生了。
此时，肌细胞只能动用储藏在内部的肌糖元通过另一种代谢过程来获得所需的能量，这种
代谢过程比较复杂，不需要氧气的参与，但能量转换效率要比有氧代谢低多了。
有氧代谢的副产品是二氧化碳，通过呼吸自然派出体外，不影响运动能力。无氧代谢在
代谢过程中却会生成许多代谢物，比如乳酸等，这些代谢物不能像二氧化碳那样能马上
派出。当积累在肌细胞周围的代谢物浓度太高时，就会产生两个效应：一是肌肉压缩
扩张能力减弱；二是刺激神经单元，使人感到酸涨疲倦。两个效应合在一起就是运动效率
的被迫降低。

发帖数: 2679 | 20 这一篇写得好，很专业。与俺的泛泛而谈从宏观上描述不同，这篇从微观入手，
分析得更细致清晰，特别适合和LZ一样有一些生化背景的人阅读。俺即达到了
抛砖引玉的目的，同时也学到些东西。
俺不在这个领域做事，不怎么关心机体在运动时微观机制，但比较注重其宏观效应。
讨论有氧无氧的动机是探索其对运动效率和大多数人关心的减肥的影响。
在这个帖子中，从ATP的角度看，无氧代谢（anaerobic glycolysis）的能量
利用率比有氧代谢（aerobic oxidation)要低多了，前者每个glucose只能产生
2分子ATP，而后者则可产生36分子ATP。从减肥的角度看，低效的能量利用率无疑是
个福音，单位的时间内可以燃烧更多的热量。但有氧运动由于代谢物的堆积，做不长。
而无氧运动虽然单位时间内消耗的热量低，但却可以作很长。如果不计投入的时间的话，
最终也能有很好的减肥效应。
俺觉得把这两者结合起来，就能get the best from both worlds，而这种运动
就是HIIT或CROSSFIT。所以热衷于高效减肥的，应该多考虑这种混合型的运动。

Weight lifting is anaerobic in most occasions. But if you do small weights

If you significantly reduced body weight, that can partially explain the

Mark Allen那里quote来的。
他那个文章是讲，不管你max多高，都要按照180-年龄，然后加一些modification算你

跳。不是说max高了，这个就能随之高。
我现在暂且认为我max很高，所以这个想搞明白一点。 |

发帖数: 10018 | 31 那些公式220-age算maxHR，180-age算max aerobic HR，都是统计规律。
平均来说，max aerobic HR跟max HR差个40点。
新手可能差个50点以上，maxHR-50就变成anaerobic了。
老手(包括those who train too high too often)可能只差过30点，
也就是他说的their max will be very high，说的是max aerobic HR。
最后一句but without having any faster times不容易理解，
说的是如果你老是高心跳训练，你能忍受的aerobic心跳比普通人高，
但是这种训练不会让你在相同心跳(或者百分比)下跑得更快。
只有在max aerobic HR以下的心跳进行训练才能让你在相同心跳下跑得更快。
你的max HR可能很高，max aerobic HR确可能不是很高。（高不高也没那么重要）
就算我170心跳可以跑90分钟，我大多数情况在150以下的心跳训练的。
用保守一点的心跳来训练没有坏处。
