The increases in systolic BP (SBP) and diastolic BP (DBP) observed during MAT and SI were similar: r = 0.88 and r = 0.68, respectively (p<0.0001, both). The percentage of hyperreactive subjects, defined as those presenting an absolute increase in SBP>or = 25 mmHg and/or an increase of DBP>or = 15 mmHg was greater between those with slightly high blood pressure (70%) and high blood pressure (43%) in both tests than among the normotense subjects of the control groups (28%) (p<0.05)
