was used to test for change in diet prior to each visit. Body Composition Total body 3-compartment body composition was measured using dual-energy X-ray absorptiometry to determine total fat-free mass (GE Lunar Prodigy; GE Healthcare, Madison, WI). Dual energy X-ray absorptiometry has been shown to be

-body dual-energy X-ray absorptiometry (DXA) scan. After the body-composition assessments, the subjects completed a familiarization session for the CP 3-minute all-out test (CP 3MT ). The second visit involved the determination of CP and AWC from the CP 3MT . CP was defined as the mean power output over the

using dual-energy X-ray absorptiometry on Days 3 and 10 (Lunar iDEXA; GE Medical Systems, Madison, WI). To minimize and standardize the acute effects of postural fluid shift, subjects were asked to lie supine for at least 15 min prior to each scan. Muscle for immunohistochemical analysis was mounted on

therapy should be prioritized. Although previously, reduced BMD was detected only when it led to the first bone fracture (ie, osteoporosis), today a person’s BMD can be measured accurately and reliably using bone densitometry (dual-energy X-ray absorptiometry). 11 – 13 Dual-energy X-ray absorptiometry
