Body composition
stature, FM
Body composition was assessed via whole-body dual-energy x-ray absorptiometry scans (DXA; GE Lunar iDXA, GE Medical Systems Ultrasound & Primary Care Diagnostics, Madison, WI, USA) to characterize the stature of the sample. Participants were placed in the center of the scanning table after removing shoes and any clothing or jewelry containing metal or hard plastic. Participants were instructed to minimize movement during the scan, which was used to estimate lean mass (LM), fat mass (FM), and body fat percentage (BF%). Regions-of-interest from the default software (enCORE Software version 16) were adjusted by a trained technician. DXA test-retest reliability from this laboratory for individuals of similar stature included an ICC = 0.98 and SEM = 0.85 kg for FM, ICC = 0.99 and SEM = 1.07 kg for LM, and ICC = 0.96 and SEM = 1.279% for %fat.
