Values are means ± SD. PWV, pulse wave velocity (central: carotid to femoral, leg: femoral to dorsalis pedis); SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; HR, heart rate. P values are group × time interaction. No interactions or main effects were observed.
