Can exercise improve your dopamine baseline?

Many people are looking for ways to regulate their mood naturally, and I have been trying to figure out how physical activity actually affects the brain. I keep hearing that movement changes your neurochemistry, but I am curious about the specific mechanisms regarding dopamine.

Is there any solid evidence that regular exercise can actually improve or raise your baseline dopamine levels, rather than just providing a short-term spike during the workout? I want to know if it has any long-term effects on how the brain manages dopamine regulation or receptor sensitivity. Any insight or research would be helpful.
