BACKGROUND Advances in dual-energy X-ray absorptiometry (DXA) software algorithms have improved the accuracy of this method for body-composition measurement. OBJECTIVE Our objective was to compare the utility of DXA, underwater weighing (UWW), and a multicomponent model (MC) for assessing changes in body composition. DESIGN : Previously sedentary women aged 40-66 y were randomly assigned to...

Body Mass Index (BMI) is a weight-to-height ratio used as a quick and easy guide to obesity classification. BMI of 30 or greater is indicative of excess body fat and has been labelled as increasing the risk of degenerative diseases such as cardiovascular disease and diabetes. Body fat percentage is also assessed through skinfold thickness measurement.. The aim of this study was to estimate the ...

OBJECTIVES The objective of this study was to examine if, in the general population, physically active adults have less body fat after taking body mass index (BMI) into account. DESIGN A cross-sectional analysis of participants recruited into UK Biobank in 2006-2010. SETTING UK Biobank assessment centres throughout the UK. PARTICIPANTS 119 230 men and 140 578 women aged 40-69 years, with ...

An experiment using 81 crossbred swine was conducted to evaluate quantitative and percentage chemical compositional changes of swine from 1.5 kg (birth) to 145 kg body weight. Groups of eight pigs were sacrificed at 1.5, 6.4 and 18 kg, and then at 18 kg increments to 145 kg. Body composit ion was determined by grinding the entire body, minus digesta, partit ioning the carcass from other body co...

OBJECTIVE To evaluate the quality of weight change (change in fat mass vs fat-free mass [FFM]), changes in cardiorespiratory fitness (CRF), and frequencies of metabolic risk factors in adolescent females with obesity who either lost or gained weight following lifestyle treatment. STUDY DESIGN Fifty-eight girls (mean age = 13.0 ± 1.6 years; 77% black; mean body mass index = 36.5 ± 4.5 kg/m(2))...

Obesity is a leading cause of morbidity and mortality, yet is preventable. This study aimed to investigate associations between body mass index, body fat percentage and obesity-related eating behaviors. Women (n = 116; 18-44 years) were measured for height, weight and body fat using air displacement plethysmography (BodPod). Women completed the validated Three Factor Eating Questionnaire to ass...

INTRODUCTION Aerobic capacity of athletes is an important element of success in sports achievements. It is generally considered the best indicator of cardio respiratory endurance and athletic fitness. Body fat percentage affects VO2 max and thus the cardiovascular status of the athletes. The present study was undertaken to assess the VO2 max and body fat percentage in athletes. The secondary ob...

BACKGROUND This study investigated the associations of fitness and fatness with metabolic syndrome in rural women, part of a recognized US health disparities group. METHODS Fitness, percentage body fat, BMI, and metabolic syndrome criteria were assessed at baseline in 289 rural women with prehypertension, ages 40-69, enrolled in a healthy eating and activity community-based clinical trial for...

This cross-sectional study aimed to determine ethnic and environmental influences on the relationship between BMI and percentage body fat, using a sample of 144 Japanese and 140 Australian-Caucasian men living in Australia, and eighty-eight Japanese men living in Japan. Body composition was assessed by anthropometry using standard international methods (International Society for the Advancement...
