^bChange scores from baseline ± standard deviation. SBP = supine resting systolic blood pressure (mmHg), DBP = supine resting diastolic blood pressure (mmHg). HR = supine resting heart rate (bpm). LVM = left ventricular mass (gm). LVMI = LVM indexed by ht^2.7. Weight (kg). BMI = body mass index. Sum 3SF = sum of three skinfolds.
