After intense training sessions, I sometimes have the following symptoms:
- My mind races. I can still be functional and productive, but getting it to hold still long enough to make a simple decision is harder than it should be. In my journal I've used the word "scattered" to describe this feeling.
- I have trouble going to sleep, both at night and for naps.
I've read this sort of thing described as "overtraining", or "CNS fatigue", which I put in quotes because they seem to be controversial.
This forum post seems to be describing the same thing, except it has a focus on nutrition and supplements to combat these conditions.
I want to know, in terms of what's going on in the body, what these conditions are. Please include citations (preferably academic) in your answers.
