Exercise withdrawal can be mood-altering

This totally makes sense to me. Since I've started running I've become intolerably chirpy in the morning. I missed running this morning because of sleeping late, and already I feel grouchy and unfocused.

"After only one week of exercise withdrawal ... approximately three workouts missed ... there were significant increases in feelings of fatigue and decreases in feelings of vigor."After two weeks, the symptoms got worse: The subjects were more tired, depressed; they felt pangs of guilt over missing exercise.

Wow, that's really interesting. I've definitely experienced this, but to hear that losing fitness is correlated with a negative mood - enlightening.

This happens to me. I exercize every morning and it definately has an effect on my mood. And eschewing exercise also has an effect on my mood. A bad one. It may be entirely psychological or it may have something to do with fun endorphins. If I don't get my butt moving in the morning, I feel like crud on a stick all day.
