Purpose: To compare lower extremity lean mass (LELM) and lean body mass (LBM) between bioelectrical impedance analysis (BIA) devices and dual-energy x-ray absorptiometry (DXA). Methods: Thirty-one women and 26 men underwent body composition testing. Inter-instrument reliability and bias were assessed with intraclass correlation coefficients and t tests, respectively. Results: Systematic underestimation bias for LELM was observed in men (approximately 3 kg) and women (approximately 1.5 kg)(both …
