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.

Cardiac problems in athletic individuals are rare, but when they occur can be devastating. This book provides a definitive review of current practice and thinking surrounding the often difficult and life-changing practice of sports cardiology. Topics which remain a challenge for practitioners, athletes and families are investigated, including cardiovascular screening, exercise participation prescription, and prevention strategies for sudden cardiac arrest. Also given are medical guidelines for diagnosis, management and treatment of specific cardiac illnesses. Based on their earlier work Exercise and Sports Cardiology (2001), editors Paul Thompson and Antonio Fernandez have provided an updated, improved 3-part reference work for cardiologists, physicians, coaches, trainers, medical students and researchers with a comprehensive go-to reference for modern day concerns in the expanding field of sports cardiology research and treatment.

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.

The book is designed to provide a flowing description of the physiology of heat stress, the illnesses associated with heat exposure, recommendations on optimising health and performance, and an examination of Olympic sports played in potentially hot environmental conditions. In the first section the book examines how heat stress effects performance by outlining the basics of thermoregulation and how these responses impact on cardiovascular, central nervous system, and skeletal muscle function. It also outlines the pathophysiology and treatment of exertional heat illness, as well as the role of hydration status during exercise in the heat. Thereafter, countermeasures (e.g. cooling and heat acclimation) are covered and an explanation as to how they may aid in decreasing the incidence of heat illness and minimise the impairment in performance is provided. A novel and particular feature of the book is its inclusion of sport-specific chapters in which the influence of heat stress on performance and health is described, as well as strategies and policies adopted by the governing bodies in trying to offset the deleterious role of thermal strain. Given the breadth and scope of the sections, the book will be a reference guide for clinicians, practitioners, coaches, athletes, researchers, and students.

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.
