Moderate Level of Exercise may Reduce Stroke Risk
TUESDAY, 26 FEBRUARY 2008
An extensive study shows that a moderate level of aerobic fitness can significantly reduce stroke risk for men and women. According to lead author Steven Hooker, Ph.D., “Fitness has a protective effect regardless of the presence or absence of other stroke risk factors, including family history of cardiovascular disease, diabetes, high blood pressure, elevated cholesterol levels, and high body mass index.”
According to the American Stroke Association, stroke ranks as the No.3 cause of death in the US, claiming about 150,000 lives. In the study, researchers analyzed data on more than 60,000 people who participated in the Aerobics Center Longitudinal Study between 1970 and 2001.
Upon entering the study, the participants took a test to measure cardiorespiratory fitness (CRF) in which they walked on a treadmill at increasing grade and/or speed until they reached their maximal aerobic capacity.
The overall stroke risk dropped substantially at the moderate CRF level, with the protective effect persisting nearly unchanged through higher fitness levels. That corresponds to 30 minutes or more of brisk walking, or an equivalent aerobic activity, five days a week.
