This report aims to determine the efficacy and benefits of exercise in the management of depression, which is classified by the World Health Organisation as a mood disorder. In order to place exercise therapy into context, conventional methods for treating clinical depression are discussed. A personal meta-analysis is then undertaken, summarising the findings of studies that have explored the clinical significance of physical exercise as an intervention in treating depression.
