In this paper, we examined the antidepressant influence of an 8-week long aerobic exercise intervention in which two training parameters were manipulated: exercise frequency and group environment. Twenty-three individuals with elevated symptoms of depression were recruited in a sport and fitness facility and agreed to participate in this 8-week long study. They were randomly assigned to (a) a low-frequency exercise (control) group (n = 7), (b) a high-frequency exercise group (n = 8), and (c) a high-frequency exercise+group-based intervention group (n = 8). Participants completed the Beck Depression Inventory (BDI-II) at study entry, 4 and 8 weeks later. The results showed that those in the high-frequency aerobic exercise experimental groups reported lower depression scores than those in the low-frequency (control) group at 4 weeks [13.2 ± 7.3 and 11.7 ± 3.1 vs. 22.4 ± 7.5] and 8 weeks [10.9 ± 8.1 and 9.6 ± 2.5 vs. 20.7 ± 6.3]. However, alleviation in depressive symptoms was not found to be greater in those participants who received a group-based intervention.
