Body composition measurements will include gold-standard methods: dual-energy x-ray absorptiometry (DEXA) to determine fat mass [ 56, 57], total body potassium to assess body cell mass [ 58], in vivo neutron activation analysis for body nitrogen to determine total body protein [ 59], and deuterium dilution to determine total body water [ 60].
Body composition will be analyzed via an octopolar tactile bioelectrical impedance analysis (InBody720 - Biospace, Seoul, South Korea).
Body composition will be determined as weight, height, waist-to-hip circumference and BMI.
Further, body composition will be analysed using a bioelectrical impedance analysis system.
A second estimate of body composition will also be made using BODPOD™ [ 39, 40].
Weight and body composition will be measured in light clothing using BC-418 segmental body composition analyser (Tanita, Tokyo, Japan distributed by Wedderburn, Inglewood, NSW, Australia).
Body composition will be estimated using a bioimpedance analyser, the Tanita MC 180 MA Multi-Frequency Body Composition Analyzer (Tanita Corp ,Tokyo, Japan).
Body composition will be estimated using body mass index (BMI), waist circumference, waist:hip ratio (WHR), waist:height ratio and body composition (fat mass, fat-free mass) using bioimpedance analysis.
Whole body composition will be estimated with a GE LUNAR iDEXA Narrow-Angle Dual Energy X-Ray DenSmartFAN™ with SmartFAN™ (GE Medical, Software Lunar DPX enCORE 2012 version 14.0, Madison, WI).
