| Annotation | Physical exercise is seen as a promising intervention to prevent or delay cognitive decline in individuals aged 50+, yet the evidence from reviews is not conclusive. This systematic review with multilevel meta-analysis aimed to determine if physical exercise is effective in improving cognitive function in this population. Medline (PubMed), EMBASE (Scopus), PsychINFO and CENTRAL (Cochrane) were searched from inception to November 2016 for randomised controlled trials (RCTs) of physical exercise interventions in community-dwelling adults aged 50+, with an outcome measure of cognitive function. The search returned 12,820 records, of which 39 studies were included in the systematic review. Analysis of 333 dependent effect sizes from 36 studies showed that physical exercise improved cognitive function (0.29; 95% CI 0.17 to 0.41; p<0.01). Interventions of aerobic exercise, resistance training, multicomponent training and tai chi all had significant point estimates. When exercise prescription was examined, a duration of 45-60 minutes per session and at least moderate intensity, were associated with benefits to cognition. The results of the meta-analysis were consistent and independent of the cognitive domain tested or the cognitive status of the participants. Thus, physical exercise improved cognitive function in the over 50s, regardless of participants' cognitive status. To improve cognitive function, this meta-analysis provides clinicians with evidence to recommend that patients obtain both aerobic and resistance exercise of at least moderate intensity on as many days of the week as feasible, in line with current exercise guidelines.
