The Journal of the American Heart Association published a study about how the risk of having a stroke was reduced when women walked for two or more hours per week. The study included roughly 40,000 different women over ten years. Results showed that women who walked had a 30 percent lower risk of any type of stroke. For women who walked briskly (3-4mph) the chance for stroke was reduced by 37 percent. “Physical activity, including regular walking, is an important modifiable behavior for stroke prevention,” said Jacob R. Sattelmair, M.Sc., lead author and doctoral candidate in epidemiology at Harvard School of Public Health in Boston, Mass. “Physical activity is essential to promoting cardiovascular health and reducing risk of cardiovascular disease, and walking is one way of achieving physical activity.” Stroke is the leading cause of serious disability and the third leading cause of death in the United States. According to the AHA (American Heart Association) adults should be involved in at least l.5 hours of mild aerobic activity and 75 minutes of intense aerobic activity a week, to stay healthy and free from high stroke risk.
