Opis

Since the observation in the 19th century that an extract of the suprarenal bodies injected into the circulation caused a rise in blood pressure, the endocrine system has become a major component in our understanding of human physiology. The introduction of radioimmunoassay techniques and the ability to measure minimal amounts of hor- mones (a term derived from the Greek "to excite") have shown that acute exercise causes a release of a large number of hormones and that chronic exercise may further lead to long-term alterations in endocrine homeostasis. Actually, almost every organ and system in the body is affected by physical activity and exercise, much of it through the endocrine and neuroendocrine system. Investigation ofthe effect of acute or chronic physical activity on the endocrine system is a complex matter since the stimulus called "exercise" has many components, such as mode, intensity, duration, and others. In addition, several other factors, such as age, gender, training status, body temperature, circadian rhythm, metabolic state, menstrual cycle, and various external conditions as well as psychological factors, can modify the effect of physical activity on hormonal secretion. Moreover, the physiol9gical stimulus of exercise often provokes several and parallel cascades of biochemical and endocrine changes. It is therefore often extremely difficult to distinguish between primary and secondary events and between cause and effect. These limitations will be discussed in Chapter 1.

Recenzje

"...this book provides a world view of recent developments in sports endocrinology, with invited contributions from leading authorities in 12 nations...A welcome feature is an extended discussion of the exercising female, with chapters exploring hormonal changes during the menstrual cycle, contraceptive use, pregnancy and the menopause. There are also chapters looking at hormonal aspects of overtraining, exercise at high altitude, exercise and mood state, and circadian rhythms...The material should prove a valuable resource for all who are concerned with the impact of hormones upon acute and chronic responses to exercise, and this could serve as a useful text for a graduate course in sports endocrinology..." -Canadian Journal of Applied Physiology

". . .the stated objectives of the text are worthy, and the editors have met those objectives. . .the editors have done a fine job of assembling many of the outstanding figures in the field to write chapters. . .This is a very valuable book. The underlying subject -- the impact of exercise on endocrinology -- is interesting and important to both the clinician and the exercise scientist. There is a real need for a book that is a comprehensive and up-to-date presentation of the scientific findings concerning the interaction of exercise and the endocrine system. Weighted Numerical Score: 91 - 4 Stars!" -Doody's Health Science Book Review Journal

"...this book provides a good read for those interested in endocrinology and those interested in exercise. There has been a distinct need for a book in this subdiscipline, since endocrinology and exercise science e are growing so rapidly. This textbook is long overdue. A competent understanding of exercise and endocrinology are important for the successful integration of the two areas. Sports Endocrinology meets the need." -The Lancet

"...this text represents a valuable and relatively comprehensive overview of the area. It will be very useful to clinicians who treat their patients with exercise or have patients who are athletes...In summary, this is a fine book that is generally well written and well organized. It is compendium of information concerning many of the important areas of exercise endocrinology. The book is replete with interesting information not available in other single source. It would be a valuable book for clinicians who prescribe or recommend exorcise for their patients, or who have patients who are athletes. It would also be very valuable to scientists and their graduate students who study endocrinological and metabolic aspects of exercise." -Elsevier Science

"The book is impressive in scope, organization, content, and clarity. In short, this is a book with very useful, carefully crafted chapters that can indeed inform several groups of readers. It is a comprehensive review of the endocrine response to exercise and the effect on the body with up-to-date references. Sports Endocrinology is the new standard reference book." -American Journal of Medicine and Sports

"This is a comprehensive review volume describing in 24 chapters the physiological effects of physical activity on the endocrine system. Some of the topics will be of special interest to pediatric endocrinologists, such as: The effect of exercise on the hypothalamo-pituitary-adrenal-axis; Exercise and the growth hormone-IGF-I axis; Diabetes and exercise; Role of exercise in the attainment of peak bone mass and bone strength; Exercise and the developing child (interaction with growth). Well referenced. Of interest to pediatricians, endocrinologists, sports physicians and training coaches." -Journal of Pediatric Endocrinology and Metabolism

Every organ and system in the body is affected by physical activity and exercise, not least among them the endocrine system. In Sports Endocrinology, leading physicians and researchers in sports medicine comprehensively review what is known about how physical activity effects the endocrine system, and what in turn are the effects of the hormonal responses evoked on the other organs and systems of the body. Topics range from the various endocrine pathways that are altered by exercise, to the effect of hormones on performance, from the effect of exercise on puberty and growth, to the hormonal regulation of fluid homeostasis, substrate metabolism, and energy balance. A substantial section is devoted to the exercising female, and the influence of exercise-driven hormonal changes on the menstrual cycle, contraceptive use, pregnancy, and menopause. Also discussed are the role of hormones in the development of "exercise euphoria," as well as their effects on athletic performance and their consequences for long-term health.

Comprehensive and authoritative, Sports Endocrinology constitutes a major new reference source critically integrating what is known about the complex interactions of the endocrine system resulting from physical activity. All physicians and clinical investigators treating those active in sports today will find it of high value in their daily practice and research.
