4. Exercises Can Reduce Stroke Risk

A new study from researchers at the University of Alabama at Birmingham (UAB) is one of the first to study the relationship between exercise and stroke in a large biracial cohort of men and women in the United States. The findings are published in the American Heart Association journal, Stroke.

Participants consisting of 27,000 stroke-free blacks and whites ages 45 and older were classified at baseline as being inactive (i.e., no workouts in a typical week), moderately active (workouts one to three times per week) or vigorously active (workouts more than four times per week), and they were followed for an average of 5.7 years.

The results showed that physical inactivity was reported by 33 percent of participants and was associated with a 20 percent increased risk of stroke. Those who reported they exercised at least four times a week were less likely to experience a stroke or mini-stroke. Among men, only those who exercised four or more times a week had a lower stroke risk. Among women, the relationship between stroke and frequency of activity was less clear.

Howard added that stroke is preventable, and physical activity is a major modifiable risk factor for stroke. "This should be emphasized more in routine physician check-ups, along with general education on the proven health benefits of regular physical activity on other stroke-risk factors including high blood pressure, weight and blood sugar.
