High blood pressure is a leading risk factor for cardiovascular disease. Traditionally, one of the ways to treat or prevent high blood pressure is to prescribe aerobic exercise training (i.e. brisk walking). Stretching may also be effective because it may cause changes in blood vessel stiffness and therefore reduce resistance to blood flow. The study will assess a group of individuals (i.e. 96) participating in a supervised stretching or walking program five days per week for six months to determine whether stretching is superior for reducing blood pressure. This research will contribute to recommendations about the most effective exercise programs for reducing blood pressure and risk of cardiovascular disease.
