Book Description
High intensity interval training has become popular to produce various physiological benefits. There is much controversy over what type of interval training has the greatest effects. Purpose: This study was designed to compare high intensity interval groups to examine levels of post-exercise hypotension (PEH). Methods: Young, healthy volunteers (N=55) performed 24 workout sessions on a stationary bike over an 8 week period. Subjects were randomly placed into three different exercise groups: Tabata, Meyer, and steady state. Tabata (N=21) performed 20 seconds at 170% power output (PO) of VO2 max and 10 second rest for 8 bouts. Meyer (N=15) performed 30 seconds at 100% PO of VO2 max, with 60 seconds active recovery, for a total of 20 minutes. Steady state (N=19) performed 20 minutes of exercise at 90% ventilatory threshold (VT). Blood pressures were measured once a week and multiple times during those sessions. Measurements of PEH were taken 30 minutes after exercise. Results: There were significant differences in systolic blood pressure (SBP) between pre- and post-exercise but no significant differences between the three exercise groups. Averaged over eight weeks, steady state had PEH of 9.1 + 2.17, Meyer showed PEH of 8.3 + 1.83 while Tabata had PEH of 9.1 + 1.55. There was no significant difference in PEH between the weeks. Conclusions: Through this study, we have concluded that PEH occurs in SBP 30 minutes after exercise, regardless of exercise intensity. During the eight week training, PEH remained constant. Previous findings have concluded similar results, including studies involving blood pressure medication.

Book Description
Subjects with prehypertension are at risk for developing hypertension (HTN). Hypertension is associated with low-grade systemic inflammation (LGSI). Aerobic exercise training (ET) is a proven means to reduce both blood pressure and LGSI in healthy and diseased subjects. Recently, high intensity interval training (HIIT) has been show to elicit similar cardiovascular and metabolic adaptations as ET in healthy and at-risk populations in a more time efficient manner. Therefore, we hypothesized that HIIT would elicit greater reductions in blood pressure and LGSI than ET. Twelve pre-hypertensive subjects (systolic blood pressure 127.0 ± 8.5 mmHg; diastolic blood pressure 86.2 ± 4.1 mmHg) were randomly assigned to an ET group (n=5) and a HIIT group (n=7). All subjects performed an incremental test to exhaustion (VO2max) on a cycle ergometer prior to, after 4 weeks, and after 8 weeks of training. Resting heart rate and blood pressure were measured prior to and three times a week during training. LGSI was measured via high-sensitivity C-reactive protein (hs-CRP) prior to, after 4 weeks and after 8 weeks of training. ET subjects performed an eight week exercise training program at 40% VO2 reserve determined from the VOVO2[subscript]max test, while HIIT subjects performed exercise at 60% peak power determined from the VO2[subscript]max test. ET group trained four days/week while HIIT trained three days/week. ET exercised for 30 minutes continuously at a constant workload and cadence of 60 rpm while HIIT performed a protocol on a 1:1 work-to-rest ratio at a constant workload and cadence of 100 rpm. Both groups showed similar (p0.05) decreases in mean arterial (ET = -7.3%, HIIT = -4.5%), systolic (ET = -6.6%, HIIT = -8.8%), and diastolic (ET= -9.7, HIIT= -8.2%) blood pressure. HIIT decreased in LGSI ( -33.7%) while ET did not change LGSI (p0.05). VOVO2[subscript]max increased ~25% with both HIIT and ET with no differences (p>0.05) between groups. These data suggest both HIIT and ET similarly decreased resting blood pressure and increased VO2max while HIIT was effective in decreasing LGSI in subjects who were pre-hypertensive.

Book Description
ABSTRACT: The purpose of the study was to investigate the acute peripheral and central blood pressure, and arterial stiffness (AIx) responses following an aerobic, resistance, and integrated concurrent exercise session. Ten resistance trained males (M = 20.8±1.69) performed aerobic exercise (AER), resistance exercise (RES), and integrated concurrent exercise (ICE) sessions in random order following familiarization. The AER session consisted of 45 minutes of cycle simulator exercise at 70% HRres, while the RES and ICE sessions consisted of the performance of 5 resistance exercises preceded by two minutes of seated rest or cycle simulator exercise at 70% HRres respectively. Cardiovascular parameters including central and peripheral systolic and diastolic blood pressures (cSBP, cDBP, pSBP, and pDBP respectively) and AIx were collected prior to and 0, 15, 30, 45, and 60 minutes post exercise. Relative to baseline, cSBP was significantly reduced following RES 30, 45, and 60 minutes post exercise and following ICE 15 minutes post exercise (p ≤ .05). Peripheral SBP was significantly reduced following AER 60 minutes post exercise, following RES 15, 30, and 45 minutes post exercise, and following ICE 15 and 45 minutes post exercise (p ≤ .05). Augmentation Index was significantly elevated following RES 0 and 15 minutes post exercise (p ≤ .05) but was not found to significantly increase following AER or ICE. A significant increase in AIx following RES but not ICE indicates the aerobic component of ICE possibly blunted an acute increase in arterial stiffness. In conclusion, AER, RES, and ICE may provide cardiovascular benefits in terms of post exercise hypotension in terms of central and peripheral blood pressure; however, ICE may provide unique benefits including a blunted increase in arterial stiffness relative to RES.

Book Description
Equi-caloric bouts of interval (INT: 5x 2:2 min at 85 and 40% VO 2max) and continuous (21 minutes at 60% VO2max) exercise were performed by 13 older prehypertensive males on separate days, at equivalent times of day, to assess the influence of exercise mode on post-exercise hypotension (PEH). Cardiovascular measures were collected for 30 min pre and 60 min post-exercise. PEH as measured by mean post-exercise systolic blood pressure (SBP) decrease, area under the SBP curve, and minimum SBP achieved, was equivalent after both conditions. SV was significantly reduced and HR was significantly elevated post-exercise after both conditions. No significant reductions in CO or TPR were observed. INT exercise provided a larger perturbation to the autonomic nervous system as measured by Baroreflex sensitivity and Heart Rate Variability. The responses elicited by acute INT exercise, with repeated exposure, may lead to greater improvements in blood pressure regulation than those associated with continuous aerobic training.

Book Description
As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.
