Overview
- The British Journal of Sports Medicine published an umbrella review led by James Cook University that pooled 63 studies covering 81 meta-analyses, about 1,000 randomized trials, and nearly 80,000 participants.
- Across analyses, exercise produced moderate improvements in depressive symptoms comparable to antidepressants and talk therapy, with smaller yet meaningful gains for anxiety.
- Aerobic activities such as running, swimming, and dancing yielded the largest effects on mood, while even routine walking was linked to measurable improvements.
- Supervised, group-based programs showed the strongest antidepressant effects, and shorter, lower-intensity sessions tended to benefit anxiety outcomes most.
- The authors recommend routine clinical prescription and inclusion in public-health policy—especially for young adults and postnatal women—while noting heterogeneous methods and a need for longer, head-to-head trials.
