The document discusses the benefits of aerobic exercise on hypertension. It notes that hypertension is a major health problem and risk factor for death. While genetics accounts for some risk, sedentary lifestyles increase risk by 30-50%. A controlled trial of 27 sedentary males with hypertension found that 10 weeks of aerobic exercise significantly reduced both systolic and diastolic blood pressure, with effects lasting over 22 hours post-exercise. Aerobic exercise is highly recommended for reducing blood pressure and cardiovascular disease risk factors.
