Objectives: This study investigates the effectiveness of 24-week aerobic and weight-training exercise plus behavior modification for mental health and quality of life (QOL) outcomes.
Methods: Mental health and QOL data was collected using the Depression Anxiety and Stress Scales and SF-36 Health Status Survey, respectively. Employees from a single work-site were randomized into either treatment or wait-list control groups.
Results: Mental Health (P = 0.005), Vitality (P < 0.001), General Health (P = 0.009), Bodily Pain (P = 0.005), Physical Functioning (P = 0.004), Depression (P = 0.048), and Stress (P = 0.036) scales significantly improved for the treatment group compared to wait-list controls after 24 weeks.
Conclusions: Multimodal exercise is as effective as other single-modality exercise treatments for depressive symptoms and, in contrast to other studies, does improve stress symptoms and QOL outcomes.
