Abstract

Background: Depression is a leading cause of disability worldwide, with significant effects on both mental and physical health. Although pharmacological and psychological interventions are commonly used for management, physical exercise has emerged as a potential adjunct treatment. This study aims to assess the effectiveness of physical exercise in managing depression by comparing its impact on depression severity to conventional treatments.
Methods: A randomized controlled trial was conducted involving 200 participants (aged 18-65) diagnosed with moderate to severe depression. The participants were divided into three groups: a physical exercise group, a pharmacotherapy group, and a psychotherapy group. Depression severity was measured using the Hamilton Depression Rating Scale (HDRS) and Beck Depression Inventory (BDI) at baseline and after 12 weeks of intervention.
Results: The physical exercise group showed a 40% reduction in depression severity, compared to 35% in the pharmacotherapy group and 30% in the psychotherapy group. The exercise group also exhibited improved physical health outcomes, including cardiovascular fitness and reduced anxiety levels.
Conclusion: Physical exercise demonstrated significant effectiveness in managing depression, with comparable results to pharmacotherapy and psychotherapy. Exercise should be considered a viable adjunct or primary intervention in the treatment of depression.
