In light of this knowledge, researchers and lay people alike have speculated that antioxidant supplementation may...

Endurance Athletes and Increased Mitochondrial Oxygen Processing
February 5, 2008 | 5 Comments
Aerobic athletes produce physical work relatively slowly over long periods of time through the hydrolysis of ATP The demand for the re-synthesis of ATP to continue muscular work during prolonged exercise is met by the oxidation of fuel (carbohydrates, fats, and some protein) in the mitochondria. Under normal resting conditions the electron transport chain (ETC) of the mitochondria uses oxygen to produce ATP and during aerobic exercise this process is greatly accelerated. In...
