The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.
Studies have clearly shown that optimal diet and nutrition can prevent skin disease. Moreover, novel nutritional components have been used experimentally to treat skin conditions. However, the clinical application of these nutrients awaits confirmation. It is thus up to health care professionals to present new knowledge in order to provide advice or treatments for skin problems. This handbook provides, in a single volume, comprehensive coverage of the relation between skin and diet and nutrition in its broadest sense. The Handbook of diet, nutrition and the skin consists of sections on general aspects of skin, nutrition and diet, micronutrients, nutraceuticals, cancer and specific skin conditions. Unique features of each chapter in this volume include relevant and useful 'key facts' which highlight interesting or important findings of the specific subjects and 'summary points' that are designed to abstract each chapter in take home messages. This handbook will be of interest to a wide range of readers, such as dermatologists, doctors, nurses and those interested in, or working within the area of skin health. This will of course also include nutritionists and dieticians, dermatologists, cosmetic scientists, health workers and practitioners, college and university lecturers and undergraduate and graduate students.
This title is directed primarily towards health care professionals outside of the United States. Designed to help readers understand and evaluate the relationship between exercise, immune function and infection risk, this book presents evidence for the "J-shaped" relationship between exercise load and infection risk. It also describes the components of the human immune system and key functions that protect the body from disease, the impact of acute and chronic psychological stress on immune function, and practical guidelines for minimizing the risk of immunodepression and infection in athletes. Further chapters explore different ways of measuring immune function, as well as the effects of heavy training on innate and specific (acquired) immunity, exercise in environmental extremes, and nutrition. Connections between exercise, infection risk, and immune function in special populations (elderly, obese, diabetic and HIV patients) are also addressed. Authored by a team of highly experienced experts. The "J-shaped" relationship between exercise load and infection risk is described, backed by current research and evidence. Components of the immune system and normal immune function are explained in detail, as well as methods for measuring immune function. The impact of acute and chronic psychological stress on immune function is presented, along with suggestions for minimizing the risk of immunodepression and infection in athletes. The effects of heavy training, exercise in environmental extremes, and nutrition are discussed with regard to their impact on innate and specific (acquired) immunity. Immune function in special populations (elderly, obese, diabetic and HIV patients) is also addressed, exploring links between exercise and infection risk in these groups. Evidence-based coverage includes a list of references in each chapter, as well as suggestions for further reading that direct readers to important texts and review articles. Information is presented in an easily accessible format, following a logical progression of material. LEach chapter begins with a list of learning objectives and ends with a list of key points to reinforce learning. A glossary at the end of the book defines all key terms and abbreviations.
The U.S. military's concerns about the individual combat service member's ability to avoid performance degradation, in conjunction with the need to maintain both mental and physical capabilities in highly stressful situations, have led to and interest in developing methods by which commanders can monitor the status of the combat service members in the field. This report examines appropriate biological markers, monitoring technologies currently available and in need of development, and appropriate algorithms to interpret the data obtained in order to provide information for command decisions relative to the physiological "readiness" of each combat service member. More specifically, this report also provides responses to questions posed by the military relative to monitoring the metabolic regulation during prolonged, exhaustive efforts, where nutrition/hydration and repair mechanisms may be mismatched to intakes and rest, or where specific metabolic derangements are present.
The Nutrition and Health series of books has as an overriding mission to provide health professionals with texts that are considered essential because each includes: a synthesis of the state of the science; timely, in-depth reviews by the leading researchers in their respective fields; extensive, up-to-date fully annotated reference lists; a detailed index; relevant tables and figures; identification of paradigm shifts and the consequences; of information between chapters, but targeted, inter-chapter refer virtually no overlap rals, suggestions of areas for future research; and balanced, data-driven answers to patient questions that are based on the totality of evidence rather than the findings of any single study. The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate. The editors, whose training is both research and practice oriented, have the opportunity to develop a primary objective for their book, define the scope and focus, and then invite the leading authori ties from around the world to be part of their initiative. The authors are encouraged to provide an overview of the field, discuss their own research, and relate the research de findings to potential human health consequences.
Recent, groundbreaking medical research has made a connection between Vitamin D deficiency and 17 types of cancers, including breast, colon, and prostate. Illnesses such as influenza, diabetes, multiple sclerosis, and coronary heart disease have also been connected to a lack of this vitamin. Until not too long ago, not getting enough Vitamin D (the sunshine vitamin) was only associated with rickets, the childhood bone disease. Now, Soram Khalsa, M.D., sheds new light on the power of this long-forgotten vitamin. He reveals how to recognize signs of Vitamin D deficiency, which has reached epidemic proportions in North America, and then shares insights from his Beverly Hills medical practice, where he normalizes his own patients’ Vitamin D levels for their optimal health.
Exercise immunology is an important, emerging sub-discipline within exercise physiology, concerned with the relationship between exercise, immune function and infection risk. This book offers a comprehensive, up-to-date and evidence-based introduction to exercise immunology, including the physiological and molecular mechanisms that determine immune function and the implications for health and performance in sport and everyday life. Written by a team of leading exercise physiologists, the book describes the characteristics of the immune system and how its components are organised to form an immune response. It explains the physiological basis of the relationship between stress, physical activity, immune function and infection risk, and identifies the ways in which exercise and nutrition interact with immune function in athletes and non-athletes. The book shows students how to evaluate the strengths and limitations of the evidence linking physical activity, immune system integrity and health, and explains why exercise is associated with anti-inflammatory effects that are potentially beneficial to long-term health. Every chapter includes useful features, such as clear summaries, definitions of key terms, discussions of seminal research studies and practical guidelines for athletes on ways to minimise infection risk, with additional learning resources available on a companion website. This is an essential textbook for any course on exercise immunology or advanced exercise physiology.
It is well understood that proper nutrition has a significant impact on sports performance. All of the essential nutrients must be supplied in the right amounts and at the right times for an athlete to achieve optimal health and performance. In addition, when devising eating strategies that will help athletes meet their goals, sports nutritionists must take account of personal preferences, social and cultural issues, and a whole range of other factors. This latest volume in the Encyclopaedia of Sports Medicine series, published by Wiley in partnership with the Medical Commission of the International Olympic Committee, Sports Nutrition covers this dynamic field in unparalleled depth and breadth, from the scientific underpinnings of nutritional science to the development of practical nutritional programs for athletes in a range of sports. Written and edited by the world’s leading authorities on nutrition in sports, this timely new reference: Provides comprehensive coverage of nutrition for both individual and team sports Presents current knowledge of macronutrients, micronutrients, and dietary supplements for the athlete, outlining both benefits and risks Offers clear guidance on the unique nutritional needs of special populations of athletes, such as vegetarian athletes, young athletes and aging athletes Includes chapters on the clinical nutritional needs of diabetic athletes and athletes with weight management issues Carries the full endorsement of the IOC Medical Commission
