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 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.

Download or read book Military Strategies for Sustainment of Nutrition and Immune Function in the Field written by Institute of Medicine and published by National Academies Press. This book was released on 1999-05-13 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Download or read book Exercise and Diabetes written by Sheri R. Colberg and published by American Diabetes Association. This book was released on 2013-05-30 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical movement has a positive effect on physical fitness, morbidity, and mortality in individuals with diabetes. Although exercise has long been considered a cornerstone of diabetes management, many health care providers fail to prescribe it. In addition, many fitness professionals may be unaware of the complexities of including physical activity in the management of diabetes. Giving patients or clients a full exercise prescription that take other chronic conditions commonly accompanying diabetes into account may be too time-consuming for or beyond the expertise of many health care and fitness professionals. The purpose of this book is to cover the recommended types and quantities of physical activities that can and should be undertaken by all individuals with any type of diabetes, along with precautions related to medication use and diabetes-related health complications. Medications used to control diabetes should augment lifestyle improvements like increased daily physical activity rather than replace them. Up until now, professional books with exercise information and prescriptions were not timely or interactive enough to easily provide busy professionals with access to the latest recommendations for each unique patient. However, simply instructing patients to “exercise more” is frequently not motivating or informative enough to get them regularly or safely active. This book is changing all that with its up-to-date and easy-to-prescribe exercise and physical activity recommendations and relevant case studies. Read and learn to quickly prescribe effective and appropriate exercise to everyone.

Download or read book The Physiology of Exercise in Spinal Cord Injury written by J. Andrew Taylor and published by Springer. This book was released on 2016-12-20 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, around the world, between 250,000 and 500,000 people suffer a spinal cord injury (SCI). Those with an SCI are two to five times more likely to die prematurely than people without a spinal cord injury, with worse survival rates in low- and middle-income countries. Dynamic aerobic requires integrated physiologic responses across the musculoskeletal, cardiovascular, autonomic, pulmonary, thermoregulatory, and immunologic systems. Moreover, regular aerobic exercise beneficially impacts these same systems, reducing the risk for a range of diseases and maladies. This book will present comprehensive information on the unique physiologic effects of SCI and the potential role of exercise in treating and mitigating these effects. In addition, it will incorporate work from scientists across a number of disciplines and have contributors at multiple levels of investigation and across physiologic systems. Furthermore, SCI can be considered an accelerated form of aging due to the severely restricted physical inactivity imposed, usually at an early age. Therefore, the information presented may have a broader importance to the physiology of aging as it relates to inactivity. Lastly, the need for certain levels of regular aerobic exercise to engender adaptations beneficial to health is not altered by the burden of an SCI. Indeed, the amounts of exercise necessary may be even greater than the able-bodied due to ‘passive’ ambulation. This book will also address the potential health benefits for those with an SCI that can be realized if a sufficient exercise stimulus is provided.
