I've lost almost 60 pounds and significantly improved my health in the last year. I'm a nutrition and fitness nerd, and I'm always interested in learning more.

Can glycogen only be used by the muscle in which it is stored in? Glycogen can be an enormous molecule: uic.edu/classes/phar/phar332/Clinical_Cases/… lists a molecular weight of 400kDa, which is somewhere around 2200 glucose molecules. According to Wikipedia, one molecule of glucose yields that order of ATP production. en.wikipedia.org/wiki/… |

Can glycogen only be used by the muscle in which it is stored in? Fair enough. I should have toned it down to "it seems likely that empirical studies will tend to be more informative than glycogen biology". |

Can glycogen only be used by the muscle in which it is stored in? That's why you shouldn't necessarily take glycogen too seriously if your goal is training success: it's only one component of a poorly understood, very complex system. I suspect that the physiology isn't well enough understood to answer the question of which muscles to work first definitively, but I'm sure empirical studies have been done which do answer the question definitively. |

It would contradict what Wikipedia says about energy usage if muscle glycogen stores were the only component of the system you're trying to exercise. Obviously that's false. There's other sources of energy released into the blood from the liver and fat cells. Additionally, tiredness is partially determined in the brain, and occurs before muscles become totally exhausted. If your brain or nerves become tired from working other muscles, you'll work later muscles less hard. |

Why can extreme athletes eat so many calories without health risk? I would also include liver and kidney function. Eating this many calories might lead to stress on the liver, as several macronutrients need to be processed by the liver in order to be used for energy (eg fructose and protein). I'm not aware of any evidence that exercise dramatically improves liver efficiency. Similarly, metabolizing this many calories produces more waste products which must be excreted by the kidneys. |
