Older people who usually walk, garden, swim or dance may have larger brains than those who remain inactive, so that their effect is equivalent to four years less brain aging, says a preliminary study to be presented at the 72nd Meeting Annual of the American Academy of Neurology in Toronto, Canada.

“These results are exciting, as they suggest that people can potentially prevent brain shrinkage and the effects of aging on the brain simply by becoming more active,” explains study author Yian Gu of Columbia University in New York (USA), and member of the American Academy of Neurology.

The researchers divided the people into three groups: those who were inactive; those who were somewhat active, which means that each week they had approximately two and a half hours of low intensity physical activity, an hour and a half of moderate physical activity or an hour of high intensity physical activity; and those who were more active, which means that each week they had seven hours of low intensity physical activity, four hours of moderate physical activity or two hours of high intensity physical activity.

“Our results add to the evidence that greater physical activity is related to greater brain volume in the elderly. It is also based on the evidence that moving the body more frequently throughout life can protect against loss of brain volume, ”adds Gu.
