Exercise for mood

Practical note

Graded moderate: the umbrella review pooled 97 meta-analyses of more than 1000 randomised trials with consistent medium effects, downgraded one level for risk of bias and the critically low quality of most included reviews. The review reported that effects were smaller in longer-duration programmes.

Practical note

Graded low, matching the review's own CINeMA rating for walking or jogging (very low for the other modalities): 218 trials and 14 170 participants with a consistent direction, but only one trial was at low risk of bias and participants could not be blinded. The review found strength training and yoga to be the most acceptable modalities.

Practical note

Graded low: the intensity gradient comes from between-trial comparisons in a network meta-analysis and an umbrella review rather than from trials that randomised people to different intensities.

Safety note

Higher-intensity exercise raises cardiovascular demand; people with heart conditions or who are new to exercise were often screened or supervised in trials.

Practical note

Graded low: observational cohort evidence (15 studies, 191 130 adults) with large heterogeneity and possible reverse causation; not upgraded despite the dose-response gradient. The recommended volume in the analysis was 8.8 marginal MET-hours a week; half that volume was associated with 18% lower risk.

Practical note

Graded low: 103 studies and 4671 participants with a consistent direction, but mood was compared before and after exercise rather than against a non-exercise control, and heterogeneity was substantial and unexplained; it did not differ by participants' health status, exercise intensity or mode.

Practical note

Graded low: observational within-person associations (correlations around 0.04 to 0.08) from an individual participant data meta-analysis of 67 datasets and 8223 participants; mood was associated with both prior and subsequent activity, so the direction runs both ways.
