“It’s increasingly clear that exercise is as good for the brain as it is for the body, The Globe and Mail reported. “You’ll score better on cognitive tests immediately after a moderate workout, and the gains accumulate over weeks of regular exercise. The mechanism is thought to involve a rise in growth-promoting brain chemicals and neurotransmitters, but it’s not clear how much or what type of exercise is most effective.
“To investigate the optimal brain-boosting exercise dose, a University of Kansas study assigned older adults to walk for between zero and 225 minutes a week for 26 weeks. As little as 75 minutes a week was enough to improve scores on a battery of cognitive tests, and there were further gains all the way up to 225 minutes. The overall pattern was that those who made the biggest improvements in aerobic fitness also saw the biggest boosts in cognitive scores. Get your body fit, in other words, and the brain will follow.”
