What is the central question of this study? This study sought to determine whether enhancement of brachial artery flow‐mediated dilatation (FMD) after acute exposure to a sustained elevation in shear stress is greater when the shear stress stimulus for FMD is also sustained. What is the main finding and its importance? Brachial artery FMD in response to a sustained (handgrip exercise) and transient (reactive hyperaemia) shear stress stimulus was enhanced to a similar extent 10 min after a 30 min handgrip exercise intervention. This suggests that prior exposure to a sustained elevation in shear stress results in a similar acute augmentation of the ability of the endothelium to transduce sustained and transient shear stress stimuli.
