Influence Of Aerobic Training On Physiopathological Mecanisms Of Systemic Hypertension
Abstract
Aerobic exercise has both acute and chronic effects on blood pressure reduction. Post-exercise hypotension results from persistent reductions in peripheral vascular resistance, mediated by the autonomic nervous system and vasodilator substances. Exercise training lowers blood pressure through a decrease in total peripheral resistance and cardiac output at rest, as a result of reductions in sympathetic neural activity and increases in baroreflex sensitivity. Additionally, exercise may reduce the levels of serum catecholamines, affects the functional activity of the vascular endothelium, improves the metabolic profile and is an important contributor to weight loss. An exercise training program with 30-60 minutes, 3-5 sessions per week at moderate intensity reduces the blood pressure in most individuals.
