Values are means ± SE; n, number of subjects. SBP, systolic blood pressure; DBP, distolic blood pressure; BMI, body mass index; DEXA, dual-energy X-ray absorptiometry; AUC_SR, shear rate area under the curve.

P < 0.05, post hoc t-test significantly different from sex-matched young subjects (n = 18);

P < 0.05, post hoc t-test significantly different between sex-matched fit (n = 12) and sedentary older subjects (n = 16).
