Document Summary
The role of arterial structure and function in cv outcomes. Goal of research in the vascular dynamics lab. Jem cheng: to broaden the understanding of the metabolic, mechanical and neural influences as potential regulators of structural, visoelastic and vasodilatory properties of peripheral arteries in humans. Arterial physiology: adventitia (elastin, collagen, nerves, blood vessels, media (smooth muscle, intima (endothelial cells) How to assess arteries: intima-media thickness (imt) Indication of vascular health: pulse wave velocity (pwv) how fast the pressure wave moves through the body) The speed at which a pulse travels through an arterial segment (aka . A higher pulse wave velocity is indicative of increased arterial stiffness. Hopp study: kids wore accelerometers for a week. More physically active, arteries stiffened at a slower rate (slower change in pwv) 12 weeks of resistance training showed reduced pwv after training. Artery walls get thicker as we age.
