Download or read book Best Practice Protocols for Physique Assessment in Sport written by Patria A. Hume and published by Springer. This book was released on 2017-12-21 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines best practice protocols for body composition analysis of high-performance athletes and provides guidance on the use of new technologies for anthropometry. While surface anthropometry has traditionally been used to assess body composition through the internationally recognised methodology of the International Society for the Advancement of Kinanthropometry (ISAK), the recent commercialisation of devices, such as bioelectrical impedance technologies, dual-energy X-ray absorptiometry (DXA), ultrasound, 3D photometry and air-displacement plethysmography (Bod Pod), has led to the non-standardised adoption of new measurement techniques. In this textbook, leading researchers detail standardisation procedures for each technology: in terms of athlete preparation, test protocols, test reporting, equipment calibration and data interpretation. Each chapter covers a different tool: how it works, what it is used to measure, and what the issues are surrounding its validity, practicality and reliability. This book provides an essential reference for device technicians and sport practitioners, ensuring that high-performance athletes are afforded accurate and comparable body composition information to guide their training routines.
Download or read book Dietary reference values for energy written by Scientific Advisory Committee on Nutrition and published by The Stationery Office. 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.
Download or read book Energy Balance in Motion written by Klaas R. Westerterp and published by Springer Science & Business Media. This book was released on 2012-12-13 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy balance can be maintained by adapting energy intake to changes in energy expenditure and vice versa, where short-term changes in energy expenditure are mainly caused by physical activity. Questions are whether physical activity is affected by over and under-eating, is intake affected by an increase or a decrease in physical activity, and does overweight affect physical activity? Presented evidence is largely based on studies where physical activity is quantified with doubly labeled water. Overeating does not affect physical activity while under-eating decreases habitual or voluntary physical activity. Thus, it is easier to gain weight than to lose weight. An exercise induced increase in energy requirement is compensated by intake while a change to a more sedentary routine does not induce an equivalent reduction of intake and generally results in weight gain. Overweight and obese subjects have similar activity energy expenditures than lean people despite they move less. There are two options to reverse the general population trend for an increasing body weight, reducing intake or increasing physical activity. Based on the results presented, eating less is most effective for preventing weight gain, despite a potential negative effect on physical activity when reaching a negative energy balance.

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.

Download or read book Burn written by Herman Pontzer PhD and published by Penguin. This book was released on 2021-03-02 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the foremost researchers in human metabolism reveals surprising new science behind food and exercise. We burn 2,000 calories a day. And if we exercise and cut carbs, we'll lose more weight. Right? Wrong. In this paradigm-shifting book, Herman Pontzer reveals for the first time how human metabolism really works so that we can finally manage our weight and improve our health. Pontzer's groundbreaking studies with hunter-gatherer tribes show how exercise doesn't increase our metabolism. Instead, we burn calories within a very narrow range: nearly 3,000 calories per day, no matter our activity level. This was a brilliant evolutionary strategy to survive in times of famine. Now it seems to doom us to obesity. The good news is we can lose weight, but we need to cut calories. Refuting such weight-loss hype as paleo, keto, anti-gluten, anti-grain, and even vegan, Pontzer discusses how all diets succeed or fail: For shedding pounds, a calorie is a calorie. At the same time, we must exercise to keep our body systems and signals functioning optimally, even if it won't make us thinner. Hunter-gatherers like the Hadza move about five hours a day and remain remarkably healthy into old age. But elite athletes can push the body too far, burning calories faster than their bodies can take them in. It may be that the most spectacular athletic feats are the result not just of great training, but of an astonishingly efficient digestive system. Revealing, irreverent, and always entertaining, Pontzer has written a book that will change how you eat, move, and live.
