An evaluation of the evidence of physical activity as a treatment for anxiety

Abstract

This review evaluates and tries to elucidate the role of physical activity as a form of treatment for anxiety. By critically appraising the the latest and most robust literature, the review identified that physical activity has an acute anxiolytic effect (small effect size) on individuals, a moderate effect size on chronic anxiety and with a some longevity effect (when studied at follow up). It was reported that the best ‘feel good' effect from exercise resulted from moderate intensity exercise of 30-45 minutes duration, more than 3 times a week for more than 12 weeks. There is some evidence to support the prescribing of physical activity as an adjunct therapy to treat generalised anxiety disorders and social anxiety, however this is less effective than pharmacotherapy and cognitive behaviour therapy.
