When I do heavy exercise I always get worse the day or 2 after and have always wondered why - this bit of an article may explain it basically exercise produces oxidants and of interest hydrogen peroxide (used to produce colitis in rats I believe) and hydroxyl radicals are specifically mentioned - could this be why I feel worse? I'm interested to try loads of anti-oxidants before my next race and see if it helps I'm also taking quite a lot of vitamin E at the moment so we'll see how that goes...
"There is an apparent contradiction here, but the key point is this: all endurance activity is associated with oxidative stress, and the higher the intensity of the exercise, the greater the stress; but regular performance of such exercise generates an adaptive response which helps to protect the body against the effects of such stress. The increased oxidative stress observed during exercise is associated with an increase in production of chemicals known as free radicals and reactive oxygen species (ROS). Radicals and ROS produced as a result of exercise include superoxide (O-2), hydrogen peroxide (H2O2), nitric oxide (NO), and hydroxyl radicals (HO). These are highly active chemical species which can work on DNA, proteins and lipids in such a way as to cause molecular cell damage and cell injury, leading in turn to accelerated ageing and disease(1). Further, oxidants may contribute to muscle fatigue and injury through cellular changes in skeletal muscle. "
