Comparison Of Dual-Energy X-Ray Absorptiometry And Bioelectrical Impedance Analysis For Assessing Fat-Free Mass In Older Adults, Sandra L. Rios, Bridget A. Mcfadden, Noberto Quiles, Anoop Balachandran

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

Dual-energy X-ray absorptiometry (DXA) is frequently used to assess sarcopenia and muscle mass in older adults. However, DXA is expensive, requires a licensed X-ray technician, and involves radiation exposure. In contrast, multi-frequency Bioelectrical Impedance Analysis (BIA) is quick, less-costly, requires no expertise, and does not involve radiation. Despite these practical advantages, comparative studies of DXA and BIA in healthy older adults are limited. PURPOSE: We compared DXA vs BIA for fat-free mass assessment and associations with power and strength in community-living older adults. METHODS: Community-dwelling older adults (N = 13, mean age = 68.5 years, 75% females) underwent both …
