2.5.2. Body Composition
Dual X-ray absorptiometry was used to measure fat mass, FFM, visceral fat, and BMD on a DXA scanner (Lunar iDXA with CoreScan module, GE Healthcare, Brøndby, Denmark). The scan was performed in a fasted state in the morning. The scan lasted approximately 10 min with the participant lying on her back on an open bed while an X-ray arm passed slowly across the body. Participants were asked not to wear metal objects on their bodies (e.g., jewelry, watches, hair clips, and zippers) and completed the scan in underwear or light clothing.
