Abstract
PURPOSE OF REVIEW: Habitual aerobic exercise is associated with lower aortic stiffness, as measured by carotid-femoral pulse wave velocity (CFPWV), in middle-aged/older adults without hypertension, but beneficial effects of aerobic exercise on CFPWV in hypertension remain contraversial. Therefore, the focus of this review is to discuss the evidence for and against the beneficial effects of aerobic exercise on aortic stiffness in middle-aged and older adults with hypertension, possible limitations in these studies, and highlight novel directions for future research. RECENT FINDINGS: Most randomized controlled intervention studies demonstrate that short-term aerobic exercise results in no reductions in CFPWV in middle-aged and/or older adults with treated or treatment-naïve hypertension. Higher aerobic fitness is not associated with lower aortic stiffness among older adults with treated hypertension. Aortic stiffness appears to be resistant to clinically relevant improvements in response to habitual aerobic exercise in the presence of hypertension among middle-aged and older adults.
