New research suggests that exercising just once a week can help protect the brain from cognitive decline, according to a study published in BJSM. Participants who engaged in 30 minutes of weekly workouts saw a 13% reduction in their risk of mild cognitive impairment.
A study of 100,000 participants in Mexico City found that those who only exercised on weekends had lower rates of mild cognitive impairment compared to those who exercised more frequently. This suggests that weekend exercise can have similar cognitive benefits as more regular physical activity.
The researchers concluded that physical activity is associated with increased brain volume, executive function, and improved memory. In fact, not exercising at all was associated with higher rates of mild cognitive impairment, which can be an indicator of future dementia risk.
Experts estimate that 1 in 10 cases of mild cognitive impairment could be prevented by exercising at least once a week. The study authors believe that weekend exercise could be a convenient and effective option for busy individuals looking to maintain brain health.
