Excessive exercise is when your body starts coming down with lot infections, viruses etc. Your immune system is weakened by excessive exercise.
..usually experienced by those who overtrain as in marathon runners who compete in too many events etc.I've even read that may this can cause cancer in later life. Probably not PROVED..Mercola had something on this http://www.mercola.com/blog/2005/jun/21/you_can_exercise_too_much
Basically if it hurts to much for too long its your body saying this level is not good for you..hence the pain:) The pain is your body hinting it may be time to back off:)
I think some people get such a kick from the highs they get addicted, but if you picking up things too easily and frequently, its time to back off a little.
A simplified link with cortisol, I suspect, would be, that exercise presumably increases adrenaline/noradrenaline?
I think cortisol is consumed in bringing these back to normal levels.
Your body will release more free cortisol from that bound with Cortisol Binding Globulin..but only up to the point it HAS it in bound form), so it can only release more cortisolExcessive exercise is when your body starts coming down with lot infections, viruses etc. Your immune system is weakened by excessive exercise.

(My logic only this para)..
A simplified link with cortisol, I suspect, would be, that exercise presumably increases adrenaline/noradrenaline?
Cortisol is consumed in bringing these back to normal levels. Your body will release more free cortisol from that bound with Cortisol Binding Globulin(CBG) on demand from the rise in adrenaline(noradrenaline) ..but only up to the point it HAS it in bound form.
So there is a limit to how much free cortisol your body can release on exercise to counteract the adrenaline surge.Also CBG is lowered if body is in poor condition..eg. diet poor, enviromental stress, emotional stress etc.TOO MUCH exercise consumes too much cortisol.. hence your immune system (which cortisol HELPS and is NEEDED for to reuce inflammation and help the immune system) weakens.
Stress is similar to exercise in the way it consumes cortisol by raising the noradrenaline /adrenaline, and also in the way that thsis release of cortisol can cause increased cortisol at the start or lower levels, but consume all the cortisol and lead to the body getting sick at higher levels over longer, more sustained, periods of time. Stress probably also reduced CBG, hence the store is not there and every little thing (I'm sure a lot here understand what I'm talking about) floor you!
OK if I got this wrong please correct me..constructive criticism of ideas most welcome as always.
