Central artery stiffness [carotid-femoral pulse wave velocity (PWV), Panel A] and peripheral artery stiffness (carotid-brachial PWV, Panel B) at baseline and during acute elevations in muscle sympathetic nerve activity using progressive levels of lower body negative pressure (−15 mmHg and −30 mmHg) in 15 young (YG) and 14 middle-age/older (MA/O) adults. Right panels depict changes (deltas, Δ) in carotid-femoral PWV and carotid-brachial PWV during LBNP in YG and MA/O. * P<0.05 vs. baseline; † P<0.05 vs. −15 mmHg.
