Download or read book Skeletal Muscle Circulation written by Ronald J. Korthuis and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 147 pages. 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.

Download or read book Fitness Measures and Health Outcomes in Youth written by Institute of Medicine and published by National Academies Press. This book was released on 2012-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.

Download or read book Principles of Exercise Testing and Interpretation written by Karlman Wasserman and published by Lww. This book was released on 2015-04-27 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this fifth edition of Principles of Exercise Testing and Interpretation, as in earlier editions, we attempt to develop conceptual advances in the physiology and pathophysiology of exercise, particularly as related to the practice of medicine. The underlying theme of the book continues to be the recognition that the most important requirement for exercise performance is transport of oxygen to support the bioenergetic processes in the muscle cells (including, of course, the heart) and elimination of the carbon dioxide formed as a byproduct of exercise metabolism. Thus, appropriate cardiovascular and ven- tilatory responses are required to match those of muscle respiration in meeting the energy demands of exercise. As depicted by the logo on the book cover, normal exercise performance requires an efficient coupling of external to internal (cellular) respiration. Appropriate treatment of exercise intolerance requires that patients' symptoms be thought of in terms of a gas exchange defect between the cell and the environment. The defect may be in the lungs, heart, peripheral or pulmonary circulations, the muscles themselves, or there may be a combination of defects. Thus, we describe the pathophysiology in gas transport and exchange that affect any site in the cardio- respiratory coupling between the lungs and the muscles. We illustrate how cardiopulmonary exercise testing can provide the means for a critical evaluation by the clinician-scientist of the functional competency of each component in the coupling of cellular to external respiration, including the cardiovascular system. To achieve this, clinical cases are used to illustrate the wide spectrum of pathophysiology capable of causing exercise intolerance"--Provided by publisher.

Download or read book The Pathway for Oxygen written by Ewald R. Weibel and published by Harvard University Press. This book was released on 1984 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is rare indeed for one book to be both a first-rate classroom text and a major contribution to scholarship. The Pathway for Oxygen is such a book, offering a new approach to respiratory physiology and morphology that quantitatively links the two. Professionalism in science has led to a compartmentalization of biology. Function is the domain of the physiologist, structure that of the morphologist, and they often operate with vastly disparate concepts and procedures. Yet the performance of the respiratory system depends both on structural and on functional properties that cannot be separated. The first chapter of The Pathway for Oxygen engages the student with the design and function of the vertebrate respiratory organs from a comparative viewpoint. The second chapter adds to that foundation the link between cell energetics and oxygen needs of the whole animal. With Chapter 3 the excitement begins--new ideas, fresh attacks on old problems, and a fuller account of the power of the quantitative approach Dr. Weibel has pioneered. The Pathway for Oxygen will be read eagerly by medical students, graduate students, advanced undergraduates in zoology--and by their professors.

Download or read book Controversies in Exercise Science written by Thomas Rowland and published by Routledge. This book was released on 2018-10-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controversies in Exercise Science introduces a series of selected unresolved issues in the field of human exercise science. The common thread to all of these topics is that, in their ultimate resolution, they offer promise of insights into the essential principles of physiological systems and how these respond to the stresses of exercise. Each case study includes an examination of research surrounding each issue; the innovative aspect, however, will be that each of these controversies will be presented in the context of an historical and/or philosophical perspective. These chapter include topics related to basic exercise physiology, sports, physical activity, and exercise health. Underlying each of these debates lie clues which may offer insights into the basic nature of living beings. Aimed at both academics and practitioners in the fields of exercise science, biology, and related sports science disciplines, Controversies in Exercise Science provides arguments for both sides of several selected contemporary controversies in the field of exercise science and, while no ultimate resolution will be provided, the goal is, rather, to offer the reader sufficient "raw material" on which he or she might make their own judgement on the matters presented.

Download or read book High Intensity Exercise in Hypoxia Beneficial Aspects and Potential Drawbacks written by Olivier Girard and published by Frontiers Media SA. This book was released on 2018-01-25 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, ‘traditional’ moderate-intensity continuous training (60-75% peak heart rate) was the type of physical activity most frequently recommended for both athletes and clinical populations (cf. American College of Sports Medicine guidelines). However, growing evidence indicates that high-intensity interval training (80-100% peak heart rate) could actually be associated with larger cardiorespiratory fitness and metabolic function benefits and, thereby, physical performance gains for athletes. Similarly, recent data in obese and hypertensive individuals indicate that various mechanisms – further improvement in endothelial function, reductions in sympathetic neural activity, or in arterial stiffness – might be involved in the larger cardiovascular protective effects associated with training at high exercise intensities. Concerning hypoxic training, similar trends have been observed from ‘traditional’ prolonged altitude sojourns (‘Live High Train High’ or ‘Live High Train Low’), which result in increased hemoglobin mass and blood carrying capacity. Recent innovative ‘Live Low Train High’ methods (‘Resistance Training in Hypoxia’ or ‘Repeated Sprint Training in Hypoxia’) have resulted in peripheral adaptations, such as hypertrophy or delay in muscle fatigue. Other interventions inducing peripheral hypoxia, such as vascular occlusion during endurance/resistance training or remote ischemic preconditioning (i.e. succession of ischemia/reperfusion episodes), have been proposed as methods for improving subsequent exercise performance or altitude tolerance (e.g. reduced severity of acute-mountain sickness symptoms). Postulated mechanisms behind these metabolic, neuro-humoral, hemodynamics, and systemic adaptations include stimulation of nitric oxide synthase, increase in anti-oxidant enzymes, and down-regulation of pro-inflammatory cytokines, although the amount of evidence is not yet significant enough. Improved O2 delivery/utilization conferred by hypoxic training interventions might also be effective in preventing and treating cardiovascular diseases, as well as contributing to improve exercise tolerance and health status of patients. For example, in obese subjects, combining exercise with hypoxic exposure enhances the negative energy balance, which further reduces weight and improves cardio-metabolic health. In hypertensive patients, the larger lowering of blood pressure through the endothelial nitric oxide synthase pathway and the associated compensatory vasodilation is taken to reflect the superiority of exercising in hypoxia compared to normoxia. A hypoxic stimulus, in addition to exercise at high vs. moderate intensity, has the potential to further ameliorate various aspects of the vascular function, as observed in healthy populations. This may have clinical implications for the reduction of cardiovascular risks. Key open questions are therefore of interest for patients suffering from chronic vascular or cellular hypoxia (e.g. work-rest or ischemia/reperfusion intermittent pattern; exercise intensity; hypoxic severity and exposure duration; type of hypoxia (normobaric vs. hypobaric); health risks; magnitude and maintenance of the benefits). Outside any potential beneficial effects of exercising in O2-deprived environments, there may also be long-term adverse consequences of chronic intermittent severe hypoxia. Sleep apnea syndrome, for instance, leads to oxidative stress and the production of reactive oxygen species, and ultimately systemic inflammation. Postulated pathophysiological changes associated with intermittent hypoxic exposure include alteration in baroreflex activity, increase in pulmonary arterial pressure and hematocrit, changes in heart structure and function, and an alteration in endothelial-dependent vasodilation in cerebral and muscular arteries. There is a need to explore the combination of exercising in hypoxia and association of hypertension, developmental defects, neuro-pathological and neuro-cognitive deficits, enhanced susceptibility to oxidative injury, and possibly increased myocardial and cerebral infarction in individuals sensitive to hypoxic stress. The aim of this Research Topic is to shed more light on the transcriptional, vascular, hemodynamics, neuro-humoral, and systemic consequences of training at high intensities under various hypoxic conditions.

The way and extent to which the power and capacity of the three major energy metabolisms are affected under a number of different conditions, such as training, hypoxia and microgravity, are also described.

Download or read book The Biology of Exercise written by Michael J. Joyner and published by Perspectives Cshl. This book was released on 2017 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exercise training provokes widespread transformations in the human body, requiring coordinated changes in muscle composition, blood flow, neuronal and hormonal signaling, and metabolism. These changes enhance physical performance, improve mental health, and delay the onset of aging and disease. Understanding the molecular basis of these changes is therefore important for optimizing athletic ability and for developing drugs that elicit therapeutic effects. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine examines the biological basis of exercise from the molecular to the systemic levels. Contributors discuss how transcriptional regulation, cytokine and hormonal signaling, glucose metabolism, epigenetic modifications, microRNA profiles, and mitochondrial and ribosomal functions are altered in response to exercise training, leading to improved skeletal muscle, hippocampal, and cardiovascular function. Cross talk among the pathways underlying tissue-specific and systemic responses to exercise is also considered. The authors also discuss how the understanding of such molecular mechanisms may lead to the development of drugs that mitigate aging and disease. This volume will therefore serve as a vital reference for all involved in the fields of sports science and medicine, as well as anyone seeking to understand the molecular mechanisms by which exercise promotes whole-body health.
