Keep Moving to Stay Alive
Writing in Stroke: Journal of the American Heart Association, public health researchers say a 13-year study of more than 11,000 male Harvard Alumni found that those who burned up to 3,000 calories weekly in regular exercise were able to cut their risk of stroke by 46 percent.
The longer the workout, the lower the risk, study authors say. Men who used up to 2,000 calories a week cut their risk of stroke by 24 percent compared with those who only walked or exercised off less than 1,000 calories.
But the intensity of the exercise is what counts. Light exercise such as working around the house had no effect. But bicycling and brisk walking did.
