We know that exercise is important as we age, but can it help the brain as well as the body?
Research at the University of Kansas Alzheimer’s Disease Center, as reported in this article in the New York Times, tested four levels of exercise against a group of sedentary older adults (at least 65 years of age). They found that a moderate amount of exercise — a brisk walk of 20-25 minutes, three times a week – improved the ability to think more clearly, control attention, and create visual maps.
Interestingly, higher levels of exercise did not lead to noticeably higher scores. That’s good news, in a way, because the level of exercise that did produce better results is certainly achievable by most of us.
