Sports Endocrinology (Contemporary Endocrinology) (Contemporary Endocrinology)

Expert physicians and researchers in sports medicine comprehensively review what is known about how such activity effects the endocrine system and how in turn these evoked hormonal responses affect many 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. Other topics include the effect of exercise on puberty and growth and the hormonal regulation of fluid homeostasis, substrate metabolism, and energy balance. A substantial part of the book is devoted to the exercising female, and the influence of exercise-driven hormonal changes on the menstrual cycle, contraceptive use, pregnancy, and menopause. Comprehensive and authoritative, Sports Endocrinology constitutes a major new reference source that critically integrates what is known about the complex interaction of the endocrine system in the sports context. It will prove immensely valuable to all physicians and clinical investigators treating those active in sports today.

the Editors Of This Book Relate Both Short- And Long-term Responses Of The Endocrine System To Acute Exercise, As Well As Chronic Exercise Training. In The Preface, They State That The Purpose Is . . .to Cover The Various Hormonal Pathways That Are Known To Be Altered By Exercise And How These Changes Affect Different Organs And Systems Of The Body . . . The Stated Objectives Of The Text Are Worthy, And The Editors Have Met Those Objectives. The Audience Is Intended To Be From The Fields Of Exercise Science And Sports Medicine. This Text Would Be Useful To Both The Clinician And The Exercise Physiologist. In Most Cases, The Text Would Not Be Appropriate At The Undergraduate Level. The Editors Are Credible Authorities. More Impressive Are The Qualifications Of The Actual Chapter Contributors. The Editors Have Done A Fine Job Of Assembling Many Of The Outstanding Figures In The Field To Write Chapters. The Selection Of Topics Appears To Take Two Tracks. In One, The Impact Of Exercise On The Function Of Various Components (organs, Axes) Of The Endocrine System Is Covered. In The Other Track, Special Conditions Are Addressed. For Instance, There Is A Discussion Of Pregnancy And The Impact Of Exercise On Relevant Hormones. In Chapter 1 Methodological Concerns In Measuring Hormonal Responses To Exercise Are Presented. This Book Is Very Helpful, And Serves As A Good Refresher To Those Who Conduct Research On This Subject. Also Valuable Are The Several Chapters On Hormonal Responses/adaptations To Exercise In Women. Likewise, With Growing Interest In The Safety And Long-term Effects Of Exercise In Children, Chapter Contributors Provide Meaningful Discussion On These Issues. Afew Important Topics Have Been Entirely Overlooked -- Chapters On The Impact Of Resistance Exercise On Hormonal Responses/adaptations, As Well As Hormonal Regulation Muscle Mass (trained Or Untrained) Should Have Been Included. 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. A Quality Comprehensive Book On The Subject Has Not Been Published Since Galbo's hormonal And Metabolic Adaptation To Exercise In 1983.

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. 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 In this text, expert physicians and researchers in sports medicine comprehensively review what is known about how physical activity effects the endocrine system and how in turn these evoked hormonal responses affect many other organs and systems of the body. The importance of hormones in regulating physiological functions and processes has intrigued scientists since they were first characterized by Baylis and Starling in 1904 (1).
