Just to play devil's advocate:
In an interesting study, healthy people were shown how to act manic with hyperkinesis and told to act that way for varying periods of time. They did not actually become manic as a result of acting manic. However, acting manic increased dopamine turnover as measured by HVA and DOPAC present in the CSF. I don't know if the same experiment has been done with depressed individuals.
It depends where in the brain the increase in dopamine neurotransmission occurs in reaction to exercise. If it occurs predominantly in the striatum and substantia nigra, areas associated with movement, I would doubt that the elevation of DA turnover is an index of a change in mood state, but rather an index of kinesis.
