Devereux and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction. Isometric exercise training (IET) is becoming established as an effective method for reducing resting blood pressure (RBP); however, the effect of different exercise intensities on RBP is not well understood. IET protocol development will allow for implementation of the most effective IET programs for reducing RBP. The primary purpose of this study was to compare the effects of two different leg isometric exercise intensities on RBP and heart rate (HR). A secondary aim of this study was to establish an IET intensity threshold at which a significant reduction in RBP occurs. Methods. Thirty-five participants were recruited for this study and randomly selected to the control, high intensity (Tl), or low intensity (T2) training group for three weeks. The participants performed four sets of two minute bi-lateral isometric exercise bouts, three days per week. RBP (mean ± SE) was measured prior to training each session. Results. The T2 group showed significant reductions from pre- to post-training of -3.6 ± 1.03 mmHg in systolic blood pressure, -4.0 ± 0.99 mmHg in diastolic blood pressure, and -3.9 ± 0.99 mmHg in mean arterial pressure. HR was reduced significantly in the T2 training group (-1.33 ± 1.06 bpm, P=0.045). These variables did not show any significant reductions in the control or the Tl groups. Conclusions. These findings show that RBP can be significantly reduced after performing bi-lateral leg isometric exercise training at 30% EMGpeak, but not at 20% EMGpeak. Therefore, the IET intensity threshold lies between 20 and 30% EMGpeak.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

This book was released on 2010 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
