Effect of levels of exercise on psychological mood states, physical fitness, and plasma beta-endorphin

Percept Mot Skills. 1986 Dec;63(3):1099-105. doi: 10.2466/pms.1986.63.3.1099.


Aerobic exercise which resulted in a significant improvement in cardiovascular functioning had no more effect on psychological mood states than did the placebo control of participation in nonaerobic recreational games or no exercise and sport at all (N = 430 college students). Beta-endorphin levels with the 41 depressed subjects were not a biochemical link that might explain the possible influence of physical activity on depression.
