New Perspectives On The Endocrinology Of Physical Activity And Sport

Understanding the influence and interaction between physical activity and the endocrine system are of paramount importance in dealing with a multitude of health problems. In Endocrinology of Physical Activity and Sport, renowned physicians and researchers provide a comprehensive and expanded update on the scientific, clinical and practical components of endocrinology as related to sport and exercise. The authors thoroughly review what is known about how such activity effects the endocrine system and how in turn these hormonal responses affect many other organs and systems of the body. In addition, aspects of endocrinology in non-glandular tissue which have endocrine actions are addressed; for example, adipocytes and the release of leptin and related adipocytokines. Further, a wide range of clinically related topics such as athletic amenorrhea, osteopenia, sarcopenia, and hypogonadism are included. This new edition critically integrates what is known about the complex interaction of the endocrine system in the sports context and will again prove immensely valuable to all physicians and clinical investigators treating those active in sports today.

Now in its fully revised and expanded third edition, this comprehensive text represents a compilation of the critical endocrinology topics in the areas of sports medicine, kinesiology and exercise science, written by leading experts in the field. As in previous editions, the focus here is on the critical issues involved in understanding human endocrinology and hormonal workings with regards to physical activity, exercise and sport and how such workings impact the full range of medical conditions, overall health and physiological adaptation. Chapters included discuss the effect of exercise on the HPA axis, the GH-IGF-1 axis, thyroid function, diabetes, and the male and female reproductive systems, among other topics. Additional chapters present the current evidence on circadian endocrine physiology, exercise in older adults, exercise and hormone regulation in weight control, and the effects of overtraining in sports. Chapters brand new to this edition present the role of hormones in muscle hypertrophy, the effect of exercise on hormones in metabolic syndrome patients, how exercise impacts appetite-regulating hormones in clinical populations, and the relative energy deficiency in sport (RED-S) condition.

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.

This valuable new addition to the Encyclopaedia of Sports Medicine series provides a comprehensive and logical look at the principles and mechanisms of endocrinology as related to sports and exercise. It looks at growth hormone factors involved in exercise and the endocrinology of sport competition. It considers various factors and stresses on the body that may alter sporting performance. It covers topics from the acute responses and chronic adaptations of the human endocrine system to the muscular activity involved in conditioning exercise, physical labor, and sport activities. This book is an essential reference for helping to plan better programs of physical fitness, to prepare for sports competitions, and to manage the medical care of athletes.

This book discusses major changes in our understanding of the most prevalent non-orthopedic, sports-related condition – overtraining syndrome (OTS), arguing that it should be considered as the manifestation of burnout in athletes, rather than simply the result of excessive training. While the chronic adaptations of the cardiovascular and musculoskeletal systems to exercise are well documented, those of the endocrine system are less well known, and adaptations of the hormonal ranges for athletes are yet to be determined. There is also a lack of standardized diagnostic criteria, consistent assessment methods and biomarkers. This book offers a systematic review of the hormonal aspects of overtraining syndrome, and a comparison with sports-related syndromes triggered by chronic deprivation of different sorts, including the female athlete triad (and its derivative, RED-S) and burnout syndrome of the athlete (BSA). It demonstrates that these conditions, although studied separately from each other, may all be different manifestations of the same condition, leading to ‘maladaptive’ (dysfunctional forced adaptations to a hostile environment) changes in response to chronic depletion of energy and mechanisms of repair, causing multiple dysfunctions. The author proposes that OTS/Paradoxical Deconditioning Syndrome (PDS), RED-S/TRIAD and BSA are parts of a same condition, or at least a group of similar conditions. Further, the book offers a chronological overview of OTS, based on preliminary research. Given its broad scope, this concise reference book will appeal to a range of health professionals. It allows readers, including those without a strong academic background, to gain a systematic understanding of OTS.

Physical activity exerts an important influence on the endocrine system, modulating synthesis and secretion of several hormones. Almost every organ and system in the body is affected by physical activity and exercise, mainly through the endocrine and neuroendocrine system. Mode, intensity, and duration of the exercise bout, age, gender and fitness level of the individual as well as environmental and psychological factors may affect the endocrine response to physical activity. On the other hand, several hormones are able to influence physical performance and body composition. Thus, a bi-univocal interrelationship between exercise and hormones exists. In this book new developments on metabolic and endocrine response to exercise are revised and introduce the "hot topic" of hormonal doping in sports. In the past decades, hormone abuse has become a widespread habit among professional and – most of all and more frequently – recreational athletes. A substantial part of this volume is devoted to the effects of exogenous hormones on performance. Anabolic steroids, growth hormone and erythropoietin properties, use and misuse in sports are widely described. Specific methods to detect hormone abuse are presented and discussed. The contributors to this volume are well-known experts and dedicated researchers in the fields of sports medicine and endocrinology, endocrine physiology, pharmacology, and doping detection. The purpose of this volume is to provide all professionals involved in sports medicine and endocrinology a state-of-the-art overview of the complex interactions between physical activity and the endocrine system and to focus on hormone abuse in sports at competitive and recreational level highlighting its negative consequences for long-term health.

2020 Choice​ Outstanding Academic Title The moving body—pervasively occupied by fitness activities, intense training and dieting regimes, recreational practices, and high-profile sporting mega-events—holds a vital function in contemporary society. As the body moves—as it performs, sweats, runs, and jumps—it sets in motion an intricate web of scientific rationalities, spatial arrangements, corporate imperatives, and identity politics (i.e. politics of gender, race, social class, etc.). It represents vitality in its productive and physiological capacities, it drives a complex economy of experiences and products, and it is a meaningful site of cultural identities and politics. Contributors to Sport, Physical Culture, and the Moving Body work from a simple premise: as it moves, the material body matters. Adding to the burgeoning fields of sport studies and body studies, the works featured here draw upon the traditions of feminist theory, posthumanism, actor network theory, and new materialism to reposition the physical, moving body as crucial to the cultural, political, environmental, and economic systems that it constitutes and within which is constituted. Once assembled, the book presents a study of bodies in motion—made to move in contexts where technique, performance, speed, strength, and vitality not only define the conduct therein, but provide the very reason for the body’s being within those economies and environments. In so doing, the contributors look to how the body moving for and about rational systems of science, medicine, markets, and geopolity shapes the social and material world in important and unexpected ways. In Sport, Physical Culture, and the Moving Body, contributors explore the extent to which the body, when moving about both ostensibly active body spaces (i.e., the gymnasium, the ball field, exercise laboratory, the track or running trail, the beach, or the sport stadium) and those places less often connected to physical activity (i.e. the home, the street, the classroom, the automobile), is bounded to technologies of life and living; and to the political arrangements that seek to capitalize upon such frames of biological vitality. To do so, the authors problematize the rise of active body science (i.e. kinesiology, sport and exercise sciences, performance biotechnology) and the effects these scientific interventions have on embodied, lived experience. Contributors to Sport, Physical Culture, and the Moving Body will be engaging a range of new and emerging theoretical perspectives, including new materialist, political ecology, developmental systems theory, and new material feminist approaches, to examine the actors and assemblages of movement-based material, political, and economic production. In so doing, contributors will vividly and powerfully illustrate the extent to which a focus on the fleshed body and its material conditions can bring forth new insights or ontological and epistemological innovation to the sociology of sport and physical activity. They will also explore the agency of the body as and amongst things. Such a performative materialist approach explicates how complex assemblages of sport and physical activity—bringing into association everything from muscle fibers and dietary proteins to stadium concrete or regional aquifers—are not only meaningful, but ecological. By focusing on the confluence of agentive materialities, disciplinary technologies, vibrant assemblages, speculative realities, and vital performativities, Sport, Physical Culture, and the Moving Body promises to offer a groundbreaking departure from representationalist tendencies and orthodoxies brought about by the cultural turn in sport and physical cultural studies. It brings the moving body and its physics back into focus: recentering moving flesh and bones as locus of social order, environmental change, and the global political economy.
