Book Description
"Arterial blood pressure may decrease below pre-exercise resting levels immediately after both aerobic and dynamic resistance exercise. This response is known as post-exercise hypotension (PEH). The purpose of this study was to determine and compare the blood pressure responses to isometric and dynamic handgrip exercise through two hours following exercise in pre-hypertensive subjects. The isometric protocol consisted of 3 sets of sustained isometric handgrip with the non-dominant arm for 3 minutes at 30% MVC. The dynamic resistance handgrip exercise protocol consisted of 3 sets of 45 rhythmic contractions at 60% MVC with the non-dominant arm for 3 minutes. Neither isometric nor dynamic handgrip exercise significantly lowered post-exercise systolic and/or diastolic blood pressure compared to the control condition."--Abstract from author supplied metadata.

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.

Book Description
Silent myocardial ischemia is a common phenomenon in patients with coronary heart disease (CHD). This may be related to findings that high BP is associated with suppression of chest pain during episodes of myocardial ischemia. Examination of the relationship between pain and cardiovascular responses during and following resistance exercise may provide insight in the phenomenon of silent ischemia. Purpose: The primary objective of this study was to examine the relationship between isometric exercise-induced muscle pain and resting blood pressure (BP) and heart rate (HR). Five exploratory objectives related to the effects of eccentric exercise pre- and two days post-exercise were also examined: 1. To examine differences in the strength of the relationship between isometric exercise-induced muscle pain ratings and resting BP and HR. 2. To examine the change in salivary cortisol. 3. To examine the differences in the strength of the relationship between non-exercising extension pain and resting BP and HR. 4. To examine the differences in the strength of the relationship between resting salivary cortisol and resting BP and HR. 5. To examine if the change in resting salivary cortisol was significantly correlated to the change in non-exercising extension pain. Methods: Thirty-two participated this randomized controlled trial, which included two exercise sessions. In the first session baseline measurements of blood pressure, HR, cortisol and pain ratings were taken. Tonic and phasic isometric muscle contraction tests were performed following all of the baseline measurements. After the isometric muscle contraction tests, participants (n=16) performed three sets of 12 eccentric muscle contractions. All of the measurements and isometric muscle contraction tests were completed again, two days post-eccentric exercise. Results: Isometric exercise-induced pain and resting BP and HR was not found to be significantly or negatively correlated. None of the relationships examined in the exploratory objectives were significant from pre- to posteccentric exercise. Salivary cortisol concentration did not significantly change pre- to posteccentric exercise. Conclusion: A negative relationship between exercise-induced pain and resting BP and HR was not detected, which may be due to several factors, such as the type of pain induced during exercise or the timing of the BP and HR measurement.

Book Description
There were two purposes to the work of this thesis (a) to identify the role of isometric training intensity in the training-induced reductions in resting blood pressure, and (b) to identify whether the mechanism for the reduced resting blood pressure is best reflected in what can be broadly termed cardiovascular, neuromuscular or metabolic markers of that training. Firstly, in a cross-sectional study, the only strong correlation was found between heart rate variability (a cardiovascular marker) and resting blood pressure. Secondly, this cardiovascular marker was also significantly affected by a single session of isometric exercise, an effect that persisted for at least 4 hours after exercise. However, thirdly, this marker and other cardiovascular markers (such as cardiac output and stroke volume) did not correlate with reductions in blood pressure seen after 4 weeks of isometric training. Instead, the training-induced reductions in blood pressure correlated strongly with neuromuscular and metabolic markers of isometric training. The extent to which local muscle fatigue was induced during isometric training correlated with the reductions in resting blood pressure. Therefore (a) isometric training intensity appears to be of utmost importance in the reductions in resting blood pressure (when bilateral-leg exercise is performed in 2 minute bouts), and (b) the mechanism whereby the adaptations in resting blood pressure occur is best reflected in neuromuscular and metabolic markers of local muscle fatigue during that training. These findings are discussed with a particular focus on the possible role of muscle metaboreceptor stimulation, during isometric training in the mechanism of training-induced reduction in resting blood pressure.

Book Description
Neural Mechanisms of Cardiovascular Regulation responds to current questions about how neurons in the central and peripheral nervous systems regulate the cardiovascular system. It includes a series of thoughtful reviews that are intended to provoke and illuminate the reader, with the intention of revealing some of the ideas that current practitioners in the field of cardiovascular research are using to generate their current studies.
