Do you think that people who do an excess of sports, do it to fill in a lack of smthng?

I am not talking about the people exercising in a competetive level.
I know some people exercise like 2 to 3h every day, to let go of the frustration, to fill in the blank and to get lost in the action etc.. And the satisfaction afterwards is like sex since your body releases endorphins etc etc
