Acute Effects of Vinyasa Yoga on Vascular Function

January 8, 2020 updated by: Texas State University

Acute Effects of Yoga on Arterial Stiffness, Wave Reflection, and Blood Markers in Normotensive and Hypertensive Adults

The purpose of this investigation was to determine the acute effects of vinyasa yoga on arterial stiffness, wave reflection, and blood markers in normo- and hyper-tensive adults. To address this aim, fifteen normotensive adults and 15 adults with elevated blood pressure or stage 1 hypertension with a minimum of 3 months of yoga practice experience were enrolled. Carotid-femoral pulse wave velocity (cf-PWV), augmentation index (AIx), lipid profile, and glucose concentrations were assessed at baseline and immediately following a 1-hour vinyasa yoga session.
