Download or read book The Role of Protein and Amino Acids in Sustaining and Enhancing Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1999-09-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nutrition and Aging written by Irwin H. Rosenberg and published by Karger Medical and Scientific Publishers. This book was released on 2002 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.

Available in PDF, EPUB and Kindle. Book excerpt: Mammalian Protein Metabolism, Volume II focuses on the processes, methodologies, and reactions involved in mammalian protein metabolism, including toxicities, amino acid imbalance, and digestion and absorption. The selection first offers information on the nutritive value of dietary proteins, amino acid toxicities and imbalances, and protein requirements. Discussions focus on the protein requirements of adults, infants, and children, amino acid requirements, protein requirements in pregnancy, amino acid imbalance, mixed diets, and nutritive value and maintenance. The text then ponders on protein metabolism and requirements in pregnancy and lactation and protein metabolism and requirements in the newborn. The publication examines protein metabolism and requirements in the elderly; anomalies of amino acid metabolism; and physical injury and its effects on protein metabolism. Topics include general disturbance of protein metabolism following physical injury, nature of inflammatory reaction, acquired disturbances of amino acid metabolism, plasma proteins, nitrogen balance, digestion and absorption, and protein withdrawal. The text then elaborates on protein metabolism and tumor growth, experimental protein-calorie deficiency, and the clinical aspects of protein malnutrition. The selection is a dependable source of data for researchers interested in mammalian protein metabolism.

Download or read book Recommended Dietary Allowances written by National Research Council and published by National Academies Press. This book was released on 1989-02-01 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction in 1943 Recommended Dietary Allowances has become the accepted source of nutrient allowances for healthy people. These Recommended Dietary Allowances (RDAs) are used throughout the food and health fields. Additionally, RDAs serve as the basis for the U.S. Recommended Daily Allowances, the Food and Drug Administration's standards for nutrition labeling of foods. The 10th Edition includes research results and expert interpretations from years of progress in nutrition research since the previous edition and provides not only RDAs but also "Estimated Safe and Adequate Daily Dietary Intakes"â€"provisional values for nutrients where data were insufficient to set an RDA. Organized by nutrient for ready reference, the volume reviews the function of each nutrient in the human body, sources of supply, effects of deficiencies and excessive intakes, relevant study results, and more. The volume concludes with the invaluable "Summary Table of Recommended Dietary Allowances," a convenient and practical summary of the recommendations.
Download or read book Protein Metabolism and Homeostasis in Aging written by Nektarios Tavernarakis and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging is loosely defined as the accumulation of changes in an organism over time. At the cellular level such changes are distinct and multidimensional: DNA replication ceases, cells stop dividing, they become senescent and eventually die. DNA metabolism and chromosomal maintenance, together with protein metabolism are critical in the aging process. The focus of this book is on the role of protein metabolism and homeostasis in aging. An overview is provided of the current knowledge in the area, including protein synthesis, accuracy and repair, post-translational modifications, degradation and turnover, and how they define and influence aging. The chapters mainly focus on well-characterised factors and pathways, but new areas are also presented, where associations with aging are just being elucidated by current experimental data. Protein turnover, the balance between protein synthesis and protein degradation are carefully maintained in healthy cells. Chapters 1 and 2 illustrate that aging cells are characterised by alterations in the rate, level and accuracy of protein synthesis compared to young ones, and that mRNA translation, essential for cell growth and survival, is controlled at multiple levels. The theory that growth and somatic maintenance are believed to be antagonistic processes is described in Chapter 3: inhibition of protein synthesis results in decreased rates of growth and development, but also confers an extension of lifespan, as shown for example by the effects of dietary restriction in various models organisms.
Download or read book Body Composition and Aging written by C. V. Mobbs and published by Karger Medical and Scientific Publishers. This book was released on 2010 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased adiposity and decreased muscle mass contribute substantially to age-dependent disease and disability. In particular age-related increase in adiposity is quickly becoming a major threat to public health throughout the world. Although the hypothesis that age-related changes in body composition are due to lifestyle choices alone is well accepted, it is a vast oversimplification. This volume reflects the current knowledge in this rapidly developing field of research. The first part of the book discusses the extent to which increased adiposity contributes to age-related diseases and longevity. The 'obesity paradox', describing the protective role of overweight in decreasing mortality while increasing pathology, is covered in depth. Further chapters address specific aspects of the regulation of energy balance during aging, including the effects of changes in food intake. Finally the causes and consequences of loss of muscle mass and age-related osteoporosis are examined. A valuable help for physicians treating elderly patients, this book will also be of great interest to researchers studying energy balance, muscle physiology, bone disease, and other aspects of aging.
Download or read book Nutrition Longevity and Aging written by Morris Rockstein and published by Elsevier. This book was released on 2012-12-02 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrition, Longevity, and Aging documents the proceedings of a symposium on ""Nutrition, Longevity, and Aging,"" held at the University of Miami School of Medicine, February 26-27, 1976, sponsored by the Training Program in Cellular Aging of the Departments of Physiology/Biophysics and Microbiology. Clinicians and research scientists working in the field of nutrition and closely related specialities were invited to relate their expertise on specific problems in the study of gerontology as well as to general aspects of the aging process. Some of the papers employed animal models—a basic tool in gerontological research—to investigate the relationship of nutrition to aging. Others discuss the effects of diet on increasing longevity as well as reducing the incidence or severity of diseases common in the aging human population (e.g., diabetes mellitus, stroke, atherosclerosis, obesity). The Editors hope that the contents of this volume will serve to stimulate clinical researchers as well as basic scientists to undertake investigations involving the nutritional basis of many of the basic problems encountered in the study of aging.

Download or read book Protein Metabolism and Nutrition written by Seerp Tamminga and published by . This book was released on 1977 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Since protein is so important in the study of nutrition, a symposium was held to examine aspects of protein metabolism in animals, including protein biosynthesis, absorption and turnover. Rates of synthesis and degradation of proteins, as well as the absorption of amino acids from the gastrointestinal tract of ruminants can now be measured. The contents of digested protein and amino acids in feed rations function as indicators for animal protein synthesis; the level of feed intake affects protein production, especially intakes of nitrogen and energy. Digestibilities of amino acids of different feeds containing crude protein are compared. Calculations of nitrogen requirements for cattle have been determined. Protein utilization is influenced by energy losses during urea formation and excretion, and maximal organic digestion depends on ammonia and pH levels. Long term feeding experiments demonstrated the amounts of protein needed for a given production. Production of animal protein in response to human protein demands are discussed.
