PURPOSE OF REVIEW

This review summarizes the current knowledge on the benefits of various exercise training modalities on subclinical atherosclerotic cardiovascular disease (ASCVD) risk factors (i.e., endothelial dysfunction, large artery stiffening, carotid artery intima-media thickening) across the adult lifespan and the moderating role of biological sex, with the goal of informing/being to inform research gaps and future research directions.

RECENT FINDINGS

Regular exercise is an effective intervention to counter subclinical risk factors for ASCVD. However, sex-specific variation has been observed in exercise training benefits. For example, aerobic exercise improves large artery stiffening in both middle-aged/older men and women and enhances endothelial function in middle-aged/older men; however, similar exercise-mediated improvements in endothelial function are not consistently observed in postmenopausal women Sex differences in exercise benefits may be related to differences in the sex hormone environment across the adult lifespan that influence cellular-molecular mechanisms, disconnecting favorable signaling in the vasculature induced by exercise training. Moreover, differences could be explained by social and/or psychological factors that make women more susceptible, on average, to barriers to exercise training compared to age-matched men.
