Whats the science behind overtraining?

[buzz]

So are you trying to tell me that there is no such thing as muscular overtraining?

no i am saying it is usually the cns that gets overtrained first.
you said this

You will lose strength when your CNS is overtrained as well. The CNS is the origin of action potentials that lead to muscle contractions.
in a way thats my point if you lose strength its difficult(not impossible) to overtrain the muscle.so the cns going is telling the body basicly you are doing to much

Roger! Over and out.

If you overtrain the CNS, your whole body becomes weaker during your workouts, but you don't really lose actual muscle strength unless you continue to overtrain the CNS. Take a week off and the strength usually comes right back, it's just your nervous system not letting you access your full strength. When you overtrain a muscle group, you have to back it off and slowly gain that strength back by rebuilding the muscle.

If you overtrain the CNS you generally mess up your hormone levels: most notably those that affect muscle growth and fat storage (reduced testosterone, reduced HGH, increased cortisol, etc.), so you end up storing more fat and not preserving or increasing muscle.
