Abstract

Examined the effects of running and meditation on beta-endorphin (β-EP), corticotropin-releasing hormone (CRH), cortisol, and mood change in 11 elite runners (mean age 31.3 yrs) and 12 highly trained meditators matched in age, sex, and personality. It was predicted that mood change after these activities would be similar when associated with similar hormonal change. There were significant elevations of β-EP and CRH after running and of CRH after meditation, but no significant differences in CRH increases between groups. CRH was correlated with positive mood changes after running and meditation. Cortisol levels were generally high but erratic in both groups. It is concluded that positive affect is associated with plasma CRH immunoreactivity, which itself is significantly associated with circulating β-EP, thus supporting a role for CRH in the release of β-EP.
