Exercise interventions for cognitive function in adults older than 50: a systematic review with meta-analysis reviews theories about potential benefits of exercise as a potential intervention for preventing, or delaying, cognitive decline, but also noted that there has been limited supporting research evidence.
The authors reviewed 39 recent studies, and concluded:
Physical exercise improved cognitive function in the over 50s, regardless of the cognitive status of participants. 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.
