In the short term, there is muscle regeneration resulting in muscle fibers of different sizes, but in the long term, the muscles atrophy and are infiltrated by fat and fibrotic tissue, which leaves them really weak.

短期内，肌肉再造成大小参差的肌纤维细胞，但是长期下去，肌肉萎缩并且脂肪组织和结缔纤维组织增渗入其间，导致肌肉无力。

People who maintain highly active lifestyles, for instance, and need adequate fuel to power morning runs or help muscle fibers recover from intense evening workouts like weightlifting might not benefit.

比如，对那些日常活高度耗能的人来说，这种断食可能没有益处；他们需要充足的燃料，来为晨跑提供动力、或使肌肉纤维从高强度的夜间锻炼（如：举重）后得到恢复。

Days in and your quickly increasing muscle size and strength, while also protecting muscle fibers against damage, making steroids ideal for exercise tolerance and recovery as well.

服用一段时间之后，你的肌肉尺寸和力量会逐渐增加，同时也会保护肌肉纤维不收到破坏，这些使得类固醇成为锻炼耐力和进行运动恢复的最佳选择。

Ribs, brisket, pork shoulder, all cuts of meat that have tons of connective tissue, the molecular glue that supports all those muscle fibers.

Those muscle fibers then form larger, string-like bundles called fascicles, which combine to form the larger rope-like muscle organ, like your biceps brachii.

这些肌肉纤维然后形成更大的、像绳子一样的束，叫做束，它们结合在一起形成更大的像绳子一样的肌肉器官，就像你的肱二头肌。

Athletes with many slow-twitch muscle fibers seem to be able to clear the lactate from their muscles faster as they move.

We've also learned that along with motor neurons and muscle fibers, ALS could involve other cell types.

我们还了到连同运动神经元和肌肉纤维，ALS可能还会涉及其他细胞类型。

The first two, shortening muscle fibers and lengthening them, generate opposing forces.

前两种包括收缩型肌肉纤维和伸长型肌肉纤维，彼此会产相对的作用力。

The researchers currently hypothesize that stretching, much like resistance training, or lifting weights, creates a mechanical load of the muscle, causing structural damage of the muscle fibers.

研究人员目前假设拉伸，像阻力训练或举重一样，会产肌肉的机械负荷，导致肌肉纤维的结构损伤。

Every time you pump a weight at the gym, your muscles experience damage, but the body recovers by forming new muscle protein strands to repair the muscle fibers.

每次你在健身房举重的时候，你的肌肉都会受损。但是身体通过形成新的肌肉蛋白链来修复肌肉纤维。

Then comes a brief period of contraction, when the myosin heads are binding, and pulling, and releasing, over and over, and the muscle fibers contract.

然后是短暂的收缩，这时肌球蛋白头一遍又一遍地结合、拉动和释放，肌肉纤维收缩。

Mechanistically, this difference might be explained by caffeine's connection to improving motor unit recruitment, or the ability of your brain and muscles to communicate and contract your muscle fibers.

从机制上讲，这种差异可能是因为咖啡因与提高运动单位募集有关，或者是与大脑和肌肉交流和收缩肌肉纤维的能力有关。

By bending in the middle and using fast twitch muscle fibers, they can whip around without ever changing their net angular momentum.
