A study suggests that 45 minutes of moderate aerobic exercise four times per week can enhance executive function in postmenopausal women.

A study published in the Journal of Alzheimer’s Disease on August 1 indicates that regular aerobic exercise may improve executive function in postmenopausal women. Researchers found that the most significant cognitive gains occurred in participants who engaged in 45 minutes of moderate aerobic activity four times per week. These improvements, which include better planning and decision-making skills, were observed within 3 to 6 months of starting the program.

Study Methodology and Findings

The research involved 93 cognitively healthy females between the ages of 20 and 67, 43% of whom were postmenopausal. Participants, all of whom had below-average cardiorespiratory fitness and did not exercise regularly, were randomly assigned to either an aerobic exercise program or a stretching-and-toning program for 6 months. Those in the aerobic group showed improvements in executive function, which encompasses working memory, cognitive flexibility, and inhibitory control.

Expert Perspectives on Cognitive Health

Medical experts noted that while the findings are encouraging, the study was a secondary analysis with a relatively small sample size, suggesting the need for further confirmation. Experts highlighted that aerobic exercise may support brain health by improving cardiovascular fitness, reducing vascular risk factors, and supporting brain plasticity. While the exercise does not prevent Alzheimer’s disease, it may help improve overall cognitive function as women age.
