Regular exercise at some point in life is a key to better cognitive health in old age, researchers say. Starting sooner is better and sustaining it longer are, too. A new British study has found that exercising at least once a month at any time in adulthood is linked to better thinking and memory function in later life. People who reported being physically active at least one to four times per month in separate surveys at the ages of 36, 43, 53, 60 to 64, and 69 had the biggest benefit. The effect was greater than for those who said they exercised frequently (more than five times a month) during at least one of the study periods but who didn’t necessarily keep it up across several surveys. “Our study suggests that engaging in any leisure-time physical activity, at any point in adult life, has a positive effect on cognition. This seems to be the case even at light levels of activity, between once to four times a month,” said Sarah-Naomi James of the MRC Unit for Lifelong Health & Aging at University College London. “What’s more, people who have never been active before, and then start to be active in their 60s, also appear to have better cognitive function than those who were never active.” The biggest benefit for thinking and memory function was seen… read on > read on >
