During exercise and training, muscular function plays a central role, not only in how we perform but also in how we respond physiologically to a variety of strains. Although muscular function has been frequently investigated in animal models, it has rarely been fully examined under the conditions of human locomotion. This book brings together newly acquired information from a wide range of experiments showing for the first time exactly how human muscles respond and perform during physical activity. Four key sections present readers with an excellent source of knowledge on muscle energetics, efficiency, adaptation, and fatigue and damage. Among the many topics discussed, it examines the ability of humans to sustain and generate mechanical power output during human locomotion and looks at how body mass and other factors influence the mechanics of distance running. It will become a lasting reference for sport scientists, coaches, physicians and athletes.

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.

It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

The Copenhagen Muscle Research Centre was founded in 1994 with the support of a grant from the Danish National Research Foundation. Among the goals for the Centre is the organization of research symposia, with the aim of bringing a limited number ofintemation ally renowned scientists together to discuss the latest developments and perspectives in their field. The first Copenhagen Muscle Research Centre Conference was held in 1995 and dealt with cardiovascular regulation. The Second Copenhagen Muscle Research Centre Confer ence was held from October 23-26, 1997. The topic of the Symposium was Muscle Metabo lism: Regulation, Exercise, and Diabetes. Seventy invited scientists from all over the world discussed their latest research related to skeletal muscle metabolism. The speakers were asked to expand on their presentations and to write short, but comprehensive, chapters about their given topics. The result is 28 peer-reviewed and edited chapters covering many if not all aspects of muscle energy metabolism related to exercise and diabetes. Emphasis is on regulation of glucose and fatty acid metabolism and the mechanisms regulating their use as fuels for the muscle during exercise. In addition, abnormalities in the regulation of glucose metabolism in the diabetic state are described. However, amino acid and protein metabolism are also thoroughly discussed. We believe that this volume brings an unparralleled, up to date, and comprehensive review of the frontiers in muscle metabolism. Erik A.

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.

This book is an up-to-date, extensive overview of the effects of physical activity and training on endocrine function. It gives insights into a complex relationship by describing effects with respect to exercise performance, growth, development, and ageing. It includes discussions of the endocrine response depending on exercise mode, intensity, and duration as well as on gender, age, and fitness level. Additionally the book deals with the impact of environmental and psychological factors on endocrine level. A substantial part of Sports Endocrinology is devoted to the 'hot topic' of hormonal doping in sports. The properties of androgens, growth hormone, erythropoietin, and dietary supplements are highlighted. The use and abuse among professional and recreational athletes is discussed and specific methods of detection are presented and explained. All contributors are well-known experts in sports medicine and endocrinology, endocrine physiology, pharmacology, and doping detection, so this book is a must-read for every professional involved in the field.
