We are often asked about the best way to prevent dementia. Our answer disappoints some people and pleases others: Exercise appears to benefit the brain. Research published this week provides data that backs up this assertion.
Studying Activity and Cognitive Performance:
Australian scientists performed a meta-analysis of 39 randomized controlled trials. They were looking for evidence that physical activity impacts cognitive function in people over the age of 50.
In these studies, volunteers who participated in at least four weeks of structured aerobic exercise scored better on tests of thinking, learning and reasoning. Those who practiced weight training demonstrated better memory and executive function. Multicomponent training and tai chi also provided measurable benefits.
It’s Never Too Late to Start Moving:
Even people whose cognitive abilities had already begun to decline reaped some benefit. The researchers concluded that,
“Physical exercise improved cognitive function in the over 50s, regardless of the cognitive status of participants.”
They suggest exercising at moderate intensity or higher as many days of the week as possible.
