Why Isn’t Flow-Mediated Dilation Enhanced in Athletes?

Abstract

Although artery FMD was lower in athletes, artery size was larger and WT smaller than controls. The apparent reduction in artery FMD may relate to the profound structural remodeling in the diameter and WT of the conduit arteries of athletes. These findings have implications for the interpretation of FMD data, particularly as it pertains to the effect of athletic endeavor on cardiovascular health.
