P < 0.01,
P < 0.05 versus respective baseline. Values reported as mean ± standard error of the mean. When significant within-subject variation was found, differences from baseline for each time point were determined using pairwise comparisons
HR, heart rate; ED, ejection duration; PSBP, peripheral systolic blood pressure; CSBP, central systolic blood pressure; PDBP, peripheral diastolic blood pressure; CDBP, central diastolic blood pressure; MAP, mean arterial pressure; Pi, central aortic pressure at inflection point
