Introduction: Cognitive impairment often serves as a transitional phase between normal aging and the development of dementia. Recent studies indicate that around 15% of individuals over 60 experience cognitive impairment. This systematic review aims to investigate the impact of aerobic exercise on cognitive function and electrical brain activity in older adults experiencing cognitive impairment.
Methods: Primary sources were gathered from three databases: PubMed, SCOPUS, and Web of Science. The search encompassed all years up to June 10, 2025. Standardized mean differences (SMD), weighted mean differences, and 95% confidence intervals (CIs) were computed for the results using either random or fixed-effect models.
Results: Following the screening process, a total of 11 studies involving 619 participants were included in this systematic review. The meta-analysis results indicated that aerobic exercise significantly enhanced cognitive function (p=0.001, [95% CI: 0.80-1.37], mean difference = 0.96) and electrical brain activity (p=0.001, [95% CI: 0.89-1.67], mean difference = 1.28) in older adults with cognitive impairment.
Conclusion: The meta-analysis revealed that aerobic exercise positively impacts cognitive function and brain electrical activity in older adults with cognitive impairment. These findings suggest that regular physical activity can enhance cognitive status and brain function in this demographic. It is advisable for trainers and rehabilitation professionals to create personalized exercise programs for older adults and to boost motivation for participation in aerobic exercise through the promotion of social activities. Additionally, conducting regular assessments of individuals' progress can aid in optimizing outcomes. |
