Еще, если кому интересно научное объяснение, как повышается производительность спортсмена, то тоже вот абстракт из разговора 2х ученых

What I don’t get out of all this is how inhibiting fatty acid metabolism is supposed to help athletic performance. As I understand it, many of the inborn errors in fatty acid metabolism involve the likelihood of abruptly dying of hypoglycemia during exertion. Is it something to do with the relative oxygen demand for carbohydrate oxidation vs. fatty acid oxidation so long as you don’t run out of glucose?

Yep. Multiple mechanisms actually. One, chopping up sugars for energy indeed requires less oxygen than doing the same with lipids. Second, carnitine fatty acid esthers actually are surfactants. At increased demand of energy and deficit of oxygen, their concentration build up and they start to damage membranes of mitochondria. Third, there is also a bunch of other unclear and not very well explained effects, like blood flow increase, possibly mediated through interaction with NO system, and short term effects of single doses (carnitine lowering happens only fter regular use of week and more).
