Book excerpt: "The IAEA has fostered the more widespread use of a stable isotope technique to assess body composition in different population groups to address priority areas in public health nutrition in Member States. It has done this by supporting national and regional nutrition projects through its technical cooperation programme and coordinated research projects over many years. This publication was developed by an international group of experts to provide practical hands-on guidance in the use of this technique in settings where analysis of stable isotope ratios in biological samples is to be made by isotope ratio mass spectrometry. The publication is targeted at new users of this technique, for example nutritionists, analytical chemists and other professionals. More detailed information on the theoretical background and the practical applications of state of the art methodologies to monitor changes in body composition can be found in IAEA Human Health Series No. 3, Assessment of Body Composition and Total Energy Expenditure in Humans by Stable Isotope Techniques."--Foreword.

Bowering was a 30-year-old poet and university student and Curnoe was a 29-year-old painter who had dropped out of art school in Toronto to return to his place of birth. Their art was in its youth, their eyes and ears were wide open and their stomachs could withstand pots and pots of strong, black coffee. For 26 years they grew up parallel, inside each other’s work. Greg Curnoe was killed on his bicycle late in 1992, struck down in the middle of his bright career. This memoir was begun in London, Ontario, on November 20, 1992.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the compilation of papers presented at the International Symposium on In Vivo Body Composition Studies, held in Houston, Texas, November 10-12, 1992. The purpose of this conference was to report on the state-of-the-art techniques for in vivo body composition measurements and to present the most recent human data on normal body composition and changes during disease. This conference was the third in a series of meetings on body composition studies held in North America, and follows the successful meetings at Brookhaven National Laboratory in 1986, and the one in Toronto in 1989. A large number of excellent research papers were offered for consideration at this Conference which demonstrates the rapid growth of the field in the last three years. However, we had to limit the presentations to approximately 90 papers which provided a broad spectrum of the applications and recent interest in the subject. The proceedings of the Brookhaven meeting "In Vivo Body Composition Studies", is published by The Institute of Physical Sciences in Medicine, London. The proceedings of the Toronto meeting "In Vivo Body Composition Studies" was published by Plenum Press in its basic life science series. Both these meetings placed more emphasis on technical aspects while the current Houston meeting tried to emphasize more the emerging clinical applications of these techniques. The general sessions used at the Conference for presentations forms the basis of the order of appearance of the papers in this book.

This book was released on 2012-05-02 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary reference values (DRVs) for energy are based on estimating the total energy expenditure (TEE) for groups of people. TEE provides a measure of the energy requirement at energy balance i.e. when energy intake matches energy expenditure. The methodology to measure TEE - the doubly labelled water (DLW) method - has advanced and as a result, the evidence base on TEE in a wide variety of population groups has expanded considerably. With the high levels of overweight and obesity currently seen in the UK and the wealth of new data now available, it was considered timely for the Scientific Advisory Committee on Nutrition (SACN) to review recommendations for the UK population. This report details the evidence and approaches SACN have considered in order to update the DRVs for energy. SACN chose a prescriptive approach to estimating energy reference values; suitable reference body weight ranges consistent with long-term good health were used to calculate energy reference values. Thus, basal metabolic rate (BMR) values were predicted using healthy reference body weights. Using this approach, if overweight groups consume the amount of energy recommended for healthy weight groups, they are likely to lose weight, whereas underweight sections of the population should gain weight towards the healthy body weight range. SACN has derived new energy reference values. For most population groups, except for infants and young children, the values have increased. DRVs should be used to assess the energy requirements for large groups of people and populations, but should not be applied to individuals due to the large variation in physical activity and energy expenditure observed between people.

Available in PDF, EPUB and Kindle. Book excerpt: Diet is a major factor in health and disease. Controlled, long-term studies in humans are impractical, and investigators have utilized long-term epidemiological investigations to study the contributions of diet to the human condition. Such studies, while valuable, have often been limited by contradictory findings; a limitation secondary to systematic errors in traditional self-reported dietary assessment tools that limit the percentage of variances in diseases explained by diet. New approaches are available to help overcome these limitations, and Advances in the Assessment of Dietary Intake is focused on these advances in an effort to provide more accurate dietary data to understand human health. Chapters cover the benefits and limitations of traditional self-report tools; strategies for improving the validity of dietary recall and food recording methods; objective methods to assess food and nutrient intake; assessment of timing and meal patterns using glucose sensors; and physical activity patterns using validated accelerometers. Advances in the Assessment of Dietary Intake describes new avenues to investigate the role of diet in human health and serves as the most up-to-date reference and teaching tool for these methods that will improve the accuracy of dietary assessment and lay the ground work for future studies.

Available in PDF, EPUB and Kindle. Book excerpt: Addresses the Aging Process and Its Effect on Sports Performance Age-related changes influence all physiological systems, including those used during exercise and sport. Highlighting masters athletes—older adults who train and compete in organized sports—Nutrition and Performance in Masters Athletes examines the extent to which regular physical training can impact these changes. This book bridges the gap between theory and practice, addressing nutritional, exercise and sport sciences, and the actual performance of masters athletes and older exercisers. It reviews in detail many age-related changes that occur in the physiological systems, provides implications of these changes for masters athletes, coaches and clinicians, explores scientifically-based methods to maximize sprint, strength and power, team sport players, endurance and ultra-endurance performance, and focuses on the unique nutritional needs of master athletes. Examines the Growing Body of Knowledge on Masters Athletes Each chapter has been written by a world-leading authority in their field. Contributors focus on a specific topic and discuss available research. Incorporating information from studies on younger and older athletes and healthy older non-athletes, they help determine the training and nutrition implications for sports medicine professionals and clinicians, masters athletes and coaches, and future research directions for academic and postgraduate students. The book includes material on endurance, ultra-endurance, speed, strength and power, and team sports athletes. Sections cover macronutrients (carbohydrate, fat and protein needs), micronutrients (vitamin and mineral needs), fluids and hydration; supplements and ergogenic aids, nutrition for chronic disease, and the training/nutrition needs of every type of masters athletes. Nutrition and Performance in Masters Athletes is highly recommended for medical and health professionals, fellow academics, postgraduates with an interest in masters athletes, as well as masters athlete coaches and masters athletes, and administrators wanting to assist their members.

This book was released on 2015-04-27 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Childhood obesity according to the World Health Organization is one of the most serious public health challenges of the 21st century. The proportion of childhood obesity is high both globally and in Sweden. This is of great concern since obese children tend to stay obese in adulthood. In order to develop strategies to prevent early childhood obesity more knowledge is needed regarding factors explaining why children become overweight and obese. Preventive strategies require accurate and easy-to-use methods to assess physical activity in response to energy expenditure as well as energy intake in young children, but such methods are largely lacking or have shown limited accuracy. The aims of this thesis were: 1) to describe the longitudinal development of body composition from 1 week to 4.5 years of age; 2) to study relationships between measures of body composition and the physical activity level (PAL) at 1.5 and 3 years of age; 3) to evaluate if heart rate recording and movement registration using Actiheart can capture variations in total energy expenditure (TEE) and activity energy expenditure (AEE) at 1.5 and 3 years; 4) to evaluate the potential of a 7-day activity diary to assess PAL at 1.5 and 3 years of age; 5) to evaluate a new tool (TECH) using mobile phones for assessing energy intake at 3 years of age. Healthy children were investigated at 1 and 12 weeks (n=44), at 1.5 (n=44), 3 (n=33) and 4.5 (n=26) years of age. Body composition was measured using air-displacement plethysmography at 1 and 12 weeks and at 4.5 years of age. At 1.5 and 3 years, body composition, TEE, PAL and AEE were assessed using the doubly labelled water method and indirect calorimetry. Heart rate and movements were recorded using Actiheart (four days) and physical activities were registered using the 7-day diary. Energy intake was assessed using TECH during one complete 24-hour period. Average percentage of total body fat (TBF) and average fat mass index (FMI) were higher (+3 to +81 %), while fat-free mass index (FFMI) was slightly lower (-2 to -9 %), in children in the study from 12 weeks until 4.5 years of age when compared to corresponding reference values. A relationship between TBF% and PAL was found both at 1.5 and 3 years of age. At 3 years, but not at 1.5 years, this could be explained by a relationship between PAL and FFMI. Actiheart recordings explained a significant but small fraction (8%) of the variation in free-living TEE at 1.5 and 3 years, and in AEE (6 %) at 3 years, above that explained by body composition variables. At 1.5 and 3 years of age, PAL estimated by means of the activity diary using metabolic equivalent (MET) values by Ainsworth et al. was not significantly different from reference PAL, but the accuracy for individuals was low. Average energy intake assessed by TECH was not significantly different from TEE. However, the accuracy for individuals was poor. The results of this thesis suggest that 1) The higher body fatness of the children in the study compared to the corresponding reference values may indicate the presence of a secular trend in body composition development characterized by a high body fatness. 2) Body fatness might counteract physical activity at 1.5 years of age when the capacity to perform physical activity is limited, but not at 3 years of age when such a capacity has been developed. 3) Actiheart recordings explained a significant but small fraction of the variation in TEE at 1.5 and 3 years, and in AEE at 3 years of age, above that explained by body composition variables. 4) The activity diary and TECH produced mean values in agreement with reference PAL and TEE, respectively, but the accuracy for individual children was low. In conclusion, the results of this thesis suggest the presence of a secular trend in body composition development in healthy Swedish children, from infancy up to 4.5 years of age, which is characterized by a high body fatness. Methods to assess physical activity and energy intake at 1.5 and 3 years of age provided some promising results on a group level, although further research is needed to increase the accuracy of these methods in individual children.

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.
