"After I exercise, I temporarily feel more energetic and upbeat. The same thing occurs when I become animated during a conversation that I am interested in. However, the magnitude of this effect is relatively small, and it is qualitatively NOT a TRUE antidepressant effect."
-------------------------------------------------
What is a "true antidepressant effect"?? Yes the temporary mood improvement of exercise is probably related to the maximization of endogenious endorphin release PEA etc, but the research seems to suggest that the benefits of exercise seem to extend much further beyond the short term boost it offers.
Adults who carried a consistant exercise routeen into retirement had much denser hippocampii than did equivilantly aged persons with no exercise routeen.Exerciseing adults with other neurodegenerative disorders (parkinson's, HD, etc) do dramatically better when they continue with exercise.
Exercise regulates endorphen release, serotonin release, neurotrophins. It regulates the genes that express CRH. It increases the number of post synaptic 5-ht1a receptors that are much lower in depressed and panic disorder patients, increases PEA, promotes neurogenesis in hippocampus and frontal cortex (most AD's only increase hippocampal neurogenesis). Desnesitieses dopamine autoreceptors and serotonin autoreceptors. Suports the glia.
Sorry, but I'd say that exemption to a benefit, is only granted to the catatonic.Linakdge
