Abstract/OtherAbstract:
Brain monoamine metabolism in rats was studied during spontaneous, long-term running in a microprocessor-controlled wheel cage. Immediately after heavy spontaneous exercise, DOPA accumulation was decreased in dopamine-rich brain regions such as the limbic forebrain and corpus striatum, indicating a decreased rate of synthesis of dopamine in brain. In contrast, DOPA accumulation was increased in the noradrenaline-predominated region of the brain stem, indicating an increased synthesis of noradrenaline in this region. Alterations in brain monoamine metabolism were normalized in exercising animals analysed 24 h after the last running period. Changes in brain monoamine metabolism may be involved in the mechanisms underlying the clinically observed psychological effects of physical exercise.
