Standing may confound reflection indices in assessments; supports dissociation of reflection magnitude from peripheral resistance in healthy adults.
Does active standing affect wave reflection and peripheral resistance in healthy older and younger individuals?
Active standing decreases reflection magnitude and augmentation index despite increasing peripheral resistance in both young and older healthy individuals, suggesting these parameters are not solely dependent on peripheral resistance.
Davis et al. (2011) studied this question.
