Depressive disorders are a problem for public health care systems worldwide [Therefore, Weigelt and colleagues [Herein, we investigate whether combined physical activity training confers stronger exercise treatment effects than aerobic activity training. Exercise treatment effects were assessed by a variety of questionnaires. The major hypothesis is that combined physical activity training is more effective than unimodal aerobic activity training with respect to depression severity (main outcome parameter). On an explorative level, we assumed that combined physical activity training would be more effective than unimodal aerobic activity training at improving overall psychopathological symptom severity, body image, social activity and cognitive complaints (secondary outcomes).
