Mora-Rodriguez R, et al. - The impact of high-intensity aerobic interval training on arterial stiffness and microvascular dysfunction was explored in this research, in patients with metabolic syndrome with hypertension. A reduction was noted in both the arterial stiffness and microvascular dysfunction through 6 months of an intense aerobic exercise program, regardless of the unchanged blood-borne cardiovascular risk factors. Training lowered the blood flow resistance in central and peripheral vascular beds in a coordinated fashion. This, in turn, led to clinically relevant reductions in hypertension.
