Research over many decades has revealed that exercise is effective for reducing symptoms of depression and anxiety. The mechanisms by which these changes occur, however, have not been widely studied, although several hypotheses have been proposed. To examine the efficacy of several of these hypotheses, a prospective, randomized exercise intervention was conducted. Volunteer student participants (N = 68, Mean age = 21.6 years), who had been sedentary for at least 2-months prior to participating in the study, completed a 7-week exercise program. Participants were randomly assigned to one of two groups: an aerobic exercise group (EX), which participated in stationary cycling at 70% of heart rate maximum, three times per week, 30 minutes per session, for all seven weeks, or a placebo-control stretching group (PC), which participated in light stretching and yoga exercises three times per week, 30 minutes per session, for all seven weeks. Participants completed several questionnaires, including measures of depression, anxiety, self-esteem, exercise self-efficacy, locus of control, drug and alcohol use, both pre- and post-test. Additionally, a small amount of blood was drawn pre- and post-test, which was subsequently analyzed for serum serotonin levels. Mixed ANOVA revealed a significant group by time interaction effect for depression, indicating that the EX group had lower levels of depression than the PC group after the intervention. ANOVA also revealed that the EX group had a larger percentage decrease in serotonin than the PC group. Percent change in serotonin was found to partially mediate the relationship between exercise and depression.
