Sarcopenia can have serious consequences for health and quality of life. As the main drivers of anabolism, resistance exercise and protein ingestion may potentially be targets for interventions to alleviate these effects. Hence, two systematic reviews were conducted. Results of Chapter 2 indicated no augmentation of the effects of RET when older adults were supplemented with protein. Chapter 3 aimed to assess the effects of protein timing and distribution, but identified only six studies indicating a lack of research in the area. In Chapter 4, habitual protein intake in older adults was assessed to identify potential areas for improvement. While total intake was sufficient, distribution across meals was highly skewed, which is suboptimal according to current thinking. Chapter 5 compared effects of even and uneven protein distributions, alongside two weeks of resistance exercise, in women ≥65 years. A stable isotope protocol (deuterated water) was used to measure muscle protein synthesis. There was no significant difference in MPS between even (trained leg 1.02%.day-1) and uneven (1.16%.day-) diets, or in muscle strength change. These results do not support the theory of an optimal protein distribution based on the maximal MPS threshold dose, although there is potential for future research.

Dietary supplement companies and the food industry spend millions to reach resistance trainers-often with exaggerated marketing messages-while health practitioners continue to counsel athletes that their interest in protein is misguided and even dangerous. There appears to be a disconnect between scientists and almost everyone else in sports nutrit

This Special Issue of Nutrients, entitled "Dietary Proteins and Muscle in Aging People", welcomes the submission of manuscripts either reporting original research or reviewing the scientific literature. Manuscripts should focus on the mechanisms linking dietary protein with muscle quality and quantity. Articles presenting results from clinical trials testing protein interventions on muscle mass and function are welcome. The Special Issue aims at including articles spanning different disciplines to explore the topic of interest. Reports from basic to clinical and population research are suitable. Articles adopting a longitudinal approach or reporting data from life-long interventions/observations in the exploration of the theme will be given special consideration. Potential topics include, but are not limited to: Description of patterns of dietary protein consumption across life Influence of dietary protein intake on the functional status of older people Preclinical and clinical studies describing the mechanisms through which protein intake modifies muscle mass and function Protein/amino acid supplementation interventions against sarcopenia, cachexia, or disease conditions associated with muscle wasting in old age Disease-specific alterations modifying the effects of dietary protein intake on skeletal muscles Effects of the interactions of dietary protein intake and gut microbiota on skeletal muscles.

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.

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.

Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients-primarily protein and carbohydrate-in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutrient timing. Theoretically, consuming the proper ratio of nutrients during this time not only initiates the rebuilding of damaged muscle tissue and restoration of energy reserves, but it does so in a supercompensated fashion that enhances both body composition and exercise performance. Several researchers have made reference to an anabolic "window of opportunity" whereby a limited time exists after training to optimize training-related muscular adaptations. However, the importance - and even the existence - of a post-exercise 'window' can vary according to a number of factors. Not only is nutrient timing research open to question in terms of applicability, but recent evidence has directly challenged the classical view of the relevance of post-exercise nutritional intake with respect to anabolism. Therefore, the purpose of this paper will be twofold: 1) to review the existing literature on the effects of nutrient timing with respect to post-exercise muscular adaptations, and; 2) to draw relevant conclusions that allow practical, evidence-based nutritional recommendations to be made for maximizing the anabolic response to exercise. Proceeds from the sale of this book go to support an elderly disabled person.

SARCOPENIA An in-depth examination of sarcopenia’s underexplored yet widespread impact within the field of gerontology Sarcopenia is common in older men and women, and yet awareness of its clinical relevance is still relatively low. Only formally included in the International Classification of Diseases in 2016, the condition may impact societies with serious health-related and financial consequences unless consistent, effective methods of identification and management are adopted. This second edition of Sarcopenia provides geriatricians and other healthcare professionals with a revised and expanded examination of this understudied and underdiagnosed condition. Edited by two leading authorities on the subject, it covers the epidemiology and diagnosis of sarcopenia, as well as treatment options and possible prevention strategies. Eight newly written chapters build upon existing knowledge with fresh data on topics including sarcopenia’s biomarkers and its impact on the healthcare economy. This important text: Defines sarcopenia and explains its clinical relevance Covers all recent scientific evidence Outlines treatment options Considers prevention strategies Discusses sarcopenia as a public health priority Features eight new chapters covering topics such as sarcopenia’s clinical management, its biomarkers, and its financial impact Containing vital information for clinicians and other professionals working in geriatric care, nursing homes, nutrition, cancer, endocrinology, surgery, sports medicine and many other specialties, Sarcopenia, second edition, is a groundbreaking and essential new resource.
