Antidepressant mechanisms of exercise
Depression is a common mental disorder worldwide and it is typically treated with antidepressants and/or psychological therapy. However, there has been a growing interest in alternative approaches, such as exercise, as methods of prevention and treatment of depression. Previous observational and interventional studies have suggested that exercise and physical activity are associated with reduced likelihood of depressive symptoms and depression. The published results indicate that especially regular exercise of moderate intensity approximately three times a week lowers the odds of depressive symptoms and depression.
