The effects of exercise on oxidative stress (TBARS) and BDNF in severely depressed inpatients.

Exercise can be an effective treatment for depression. Although the efficacy of exercise is well established, little is known concerning the biological changes associated with the antidepressant effects of exercise. A randomized, controlled trial was conducted to evaluate the effects of adding exercise to the usual treatment on the thiobarbituric acid-reactive substances (TBARS) and brain-derived neurotrophic factor (BDNF) serum levels of severely depressed inpatients.
