BACKGROUND Over the past decade, considerable attention has been paid to accurately measuring body composition in diverse populations. Recently, the use of air-displacement plethysmography (AP) was proposed as an accurate, comfortable, and accessible method of body-composition analysis. OBJECTIVE The purpose of this study was to compare measurements of percentage body fat (%BF) by AP and 2 ot...

This study characterized body composition profiles of elite American heptathletes and cross-validated skinfold (SKF) and bioelectrical impedance analysis (BIA) field method equations for estimation of percent body fat (%Fat) using dual energy x-ray absorptiometry (DXA) as the criterion. Weight, height, fat mass (FM), fat-free mass (FFM), bone mineral density (BMD), and %Fat were measured in 19 ...

Penelitian mengenai pengukuran massa lemak menggunakan alat Skinfold Caliper (SKF) dan Bioelectrical Impedance Analysis (BIA) pada atlet sudah banyak dilakukan. Keakuratan metode skinfold caliper tergantung teknik pengukuran, keahlian, pengalaman dari pengukur, sedangkan BIA lebih ringkas, hemat waktu, mudah digunakan. Tujuan adalah untuk menganalisis perbedaan rata-rata persentase tubuh antara...

The skeletal muscle has a significant role on physical functions, and the assessment of is important in critically ill patients. Computed tomography (CT), ultrasound examination, bioelectrical impedance analysis (BIA) device, biomarkers can all be used to assess mass. CT useful for accurately measuring mass, measurement conducted at third lumbar vertebra level as gold standard. However, using d...

In three separate studies (156 pigs total), dual-energy X-ray absorptiometry (DXA), bioelectrical impedance (BIA) and ultrasound were compared as methods for measuring live body composition of pigs at 60 and 100-110 kg BWt. DXA measured total body fat and lean content, BIA measurements of resistance (Rs) and reactance (Xc) were used to calculate total body lean mass and ultrasound measurements ...

Percentage of body fat is strongly associated with the risk of several chronic diseases but its accurate measurement is difficult. Bioelectrical impedance analysis (BIA) is a relatively simple, quick and non-invasive technique, to measure body composition. It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. In large epidemiologic s...

The purpose of this study was to develop and cross-validate predictive equations for estimating skeletal muscle (SM) mass using bioelectrical impedance analysis (BIA). Whole body SM mass, determined by magnetic resonance imaging, was compared with BIA measurements in a multiethnic sample of 388 men and women, aged 18-86 yr, at two different laboratories. Within each laboratory, equations for pr...

BACKGROUND In diagnosis and treatment of obesity, body composition analysis including percent body fat (%BF) is useful in the clinical setting. Because bioelectrical impedance analysis (BIA) could be used quickly, easily and was non-invasive in clinical setting, the purpose of the present study was to evaluate the usefulness of multi-frequency BIA with eight-point tactile electrodes (MF-BIA8; I...

Bioelectrical impedance analysis (BIA) models must be validated against a reference method in a representative population sample before they can be accepted as accurate and applicable. The purpose of this study was to compare the eight-electrode BIA method with DEXA as a reference method in the assessment of body composition in Korean adults and to investigate the predictive accuracy and applic...
