No group differences at pre-training, training effects or group x time interactions were found (p>0.05). PWVcr = carotid-radial pulse wave velocity, PWVbf = brachial-foot pulse wave velocity, IMT = intima-media thickness, PP = pulse pressure, CSA = cross-sectional area, CSC = cross-sectional compliance, DD = distensibilty, SI = β-stiffness index.
