Key result
A 30-minute handgrip exercise intervention similarly enhanced brachial artery flow-mediated dilatation in response to both sustained (P=0.008) and transient (P=0.013) shear stress stimuli.

Acute handgrip exercise may enhance endothelial function in healthy men; hypothesis-generating for shear-mediated vascular responses in clinical populations.

Standardized Mean Difference: 0.66
Absolute Event Rate: 0.16% vs 0.11%
p-value: p=0.008
A 30-minute handgrip exercise acutely enhances endothelial function, potentiating flow-mediated dilatation to both sustained and transient shear stress stimuli to a similar extent.
McPhee et al. (2018) studied Healthy (n=19). 30 min rhythmic handgrip exercise vs. Pre-intervention baseline was evaluated on Brachial artery flow-mediated dilatation (FMD) in response to sustained (SS) and transient (RH) shear stress stimuli (Cohen's d = 0.66, p=0.008). A 30-minute handgrip exercise intervention similarly enhanced brachial artery flow-mediated dilatation in response to both sustained (P=0.008) and transient (P=0.013) shear stress stimuli.
