| Popis: | Summary Background The BodyMetrix® BX-2000 Ultrasound device (ULTRA) shows prowess in being an effective alternative to the expense and technicality of dual-energy X-ray absorptiometry (DXA). However, this technique has not been investigated using a seven-site methodology. Subject/Objective To employ a cross-over design to investigate the agreement between ULTRA using a seven-site methodology and DXA in assessing body fat (%BF) in a normal-weight sample of college-age men and women. Methods: Subjects (n = 84, BMI = 23·6 ± 3·6 kg m−², age = 23·0 ± 4·7 years) participated in this study with %BF measurements following the manufacturer's specifications. Results Significant differences were observed between methods with ULTRA less than DXA (difference = 4·4 ± 0·8%, t-statistic = 7·27, P |
