Hypertension is one of crucial contributors accelerating cardiovascular and cerebrovascular complications. Results from epidemiology or clinical trials proved that regular moderate and low-intense aerobic exercise not only reduce the risk of hypertension, but also diminish the blood pressure in patients. Thus, participating regular aerobic exercise is one of the important strategies in the prevention and treatment for the symptoms of high blood pressure. This paper reviews the current literature on the mechanisms of exercise training on hypertension.
