Available in PDF, EPUB and Kindle. Book excerpt: Accurate determinations of body composition, fat mass (FM) and fat-free mass (FFM) are of interest to scientists as well as many individuals who serve as health and fitness practitioners. Currently, researchers and practitioners use a variety of indirect methods to determine body composition. Traditional methods of estimating percent body fat include hydrostatic weighing, skinfold anthropometry and bioelectrical impedance. Dual energy x-ray absorptiometry (DEXA), utilized most commonly to determine bone mineral content, has recently been proposed to be an accurate measure in the assessment of body composition. Hologic Inc., manufacturers of the QDR-1000/W bone densitometer, have recently developed tissue composition software which can be used to estimate percent body fat in humans. Although the Hologic QDR-1000/W has been extensively evaluated for its accuracy in measuring tissue composition in "vitro", "in vivo" validation studies of body composition have been few. Therefore, the purpose of this study was to evaluate the accuracy of the Hologic QDR-1000/W in determining human body composition by comparing values for percent fat from DEXA to values derived using a multicomponent criterion measure of body composition in a group of 51 women and 50 men aged 19-82 years. Additionally, it was of interest to make comparisons of percent body fat determinations between the multicomponent criterion model and hydrostatic weighing, skinfold measures and bioelectrical impedance. All subjects completed the various body composition procedures used to estimate percent body fat: DEXA, hydrostatic weighing (2-component model), skinfold anthropometry and bioelectrical impedance. The multicomponent (4-component) criterion model procedures induded hydrostatic weighing (body density), DEXA whole body scanning (bone mineral content), and deuterium oxide (D20) dilution in respiratory water (total body water). Results of this study failed to reveal statistically significant mean percent body fat differences between hydrostatic weighing (2-component model) and the 4-component criterion model (25.2 ± 9.4 vs. 26.7 ± 8.4%, p> 0.05) for all 101 subjects. However, differences in percent body fat were found between the 4-component model (26.7 ± 8.4%) and dual energy x-ray absorptiometry (23.2 ± 7.9%), skinfold anthropometry (24.0 ± 8.5%) and bioelectrical impedance (23.4 ± 7.5%). Among women, hydrostatic weighing (2-component model), DEXA, skinfold anthropometry, and bioelectrical impedance all provided accurate estimates of percent body fat. However, each of the various indirect methods used to predict body composition underestimated percent body fat in men.

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.

Download or read book Development of body composition and its relationship with physical activity in healthy Swedish children written by Hanna Henriksson and published by Linköping University Electronic Press. 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: Doubly indirect methods of assessing body composition are commonly used in laboratory and practical settings. The purpose of this dissertation was to expand upon the methodological discrepancies associated with various techniques, and to provide improved equations to overcome these limitations. A series of three studies was conducted to 1) improve the estimation of underwater residual lung volume (RLV), 2) systematically review and quantify the error associated with single-frequency bioimpedance analysis (SFBIA) for the determination of total body water (TBW), and 3) develop a novel equation for predicting percent body fat (%BF) from skinfolds using a criterion multi-compartment model. The first study developed an equation for the prediction of underwater RLV in healthy adults using age and height as predictor variables. The new equation produced superior validity statistics upon cross-validation compared to four existing equations, indicating that it may be used by practitioners to accurately estimate underwater RLV during hydrostatic weighing. The second study systematically reviewed and meta-analyzed 264 effects from 51 original studies designed to compare SFBIA to criterion dilution methods for TBW estimation. Although a non-significant overall effect was identified, there was significant variability associated with SFBIA methodology (i.e., frequency and resistivity index) and sample sex (% female). Moderator analyses indicated that SFBIA procedures utilizing Ht2/R at 100 kHz produced the most accurate estimate of TBW when compared to isotope dilution techniques. The third study developed a skinfold-based equation for the prediction of five-compartment model %BF in a sample of healthy adults. The new equation outperformed selected existing equations when cross-validated, indicating its potential utility for practitioners concerned with obtaining accurate estimates of %BF in the general population.

Available in PDF, EPUB and Kindle. Book excerpt: Although its underlying concept is a relatively simple one—the measurement of the human body and its parts—anthropometry employs a myriad of methods and instruments, and is useful for a variety of purposes, from understanding the impact of disease on individuals to tracking changes in populations over time. The first interdisciplinary reference on the subject, the Handbook of Anthropometry brings this wide-ranging field together: basic theory and highly specialized topics in normal and abnormal anthropometry in terms of health, disease prevention, and intervention. Over 140 self-contained chapters cover up-to-date indices, the latest studies on computerized methods, shape-capturing systems, and bioelectrical impedance, data concerning single tissues and whole-body variables, and reports from different areas of the world. Chapters feature helpful charts and illustrations, cross-references to related chapters are included, and key points are presented in bullet form for ease of comprehension. Together, the Handbook’s thirteen sections entail all major aspects of anthropometrical practice and research, including: Tools and techniques. Developmental stages, from fetus to elder. Genetic diseases, metabolic diseases, and cancer. Exercise and nutrition. Ethnic, cultural, and geographic populations. Special conditions and circumstances. The Handbook of Anthropometry is an invaluable addition to the reference libraries of a broad spectrum of health professionals, among them health scientists, physicians, physiologists, nutritionists, dieticians, nurses, public health researchers, epidemiologists, exercise physiologists, and physical therapists. It is also useful to college-level students and faculty in the health disciplines, as well as to policymakers and ergonomists.

This book was released on 2012-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.
