The Effect of Aging on Carotid Artery Wall Dynamics During Acute Maximal Resistance Exercise

A hypertensive stimulus, such as maximal resistance exercise (RE), places a large stress on the cardiovascular system, evidenced by large increases in pressure and arterial stiffness. Aging also increases central arterial stiffness and therefore results in a greater pressure response to a maximal bout of RE compared to younger adults. Two‐dimensional strain imaging of large arteries, such as the common carotid artery (CCA), provides insight into the elastic properties of the arterial wall that play an integral role in maintaining normal function during a physiologic stress. To date, it is unknown if CCA artery stiffness and strain during an acute bout of maximal RE differ in older adults (OA) compared to younger adults (YA).
