Values are mean ± SEM. Significance values are reported from between-group and between–time point repeated measures analysis of variance and Tukey post hoc analysis.
Abbreviations: AgBP, augmented blood pressure; AMAP, aortic mean arterial pressure; APP, aortic pulse pressure; ASTTI, aortic systolic tension time index; DPTI, diastolic pressure tension index; ED, ejection duration; HR heart rate; NMTC, normotensive time control; PHET, prehypertensive subject randomized to endurance training; PHRT prehypertensive subject randomized to resistance training; PHTC, prehypertensive subject randomized to time control; PMAP, peripheral mean arterial pressure; PPP, peripheral pulse pressure; SEVR, subendocardial viability ratio; ∆tp, round trip travel time of reflected pressure wave from ascending aorta to peripheral reflecting sites and back; ∆tr, systolic duration of reflected wave.
