This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.Bioelectric impedance technology has been used to estimate hydration status in different populations. The impedance procedure is painless, non-invasive and gives results quickly. Dehydration can place soldiers working in extremely hot, arid environments at increased risk for heat injuries. A quick, non-invasive field method to assess hydration could help health professionals working with soldiers in hot environments identify soldiers who are at risk of dehydration. The purpose of this study is to compare the efficacy of two commercially available impedance analyzers to estimate hydration status in 40 young men aged 18-30 years. On a single visit, we will assess total body water using deuterium (non-radioactive isotope) as a reference method. Total body water will also be estimated using the Xitron multifrequency bio-electric impedence analyzer and the new handheld Nova Industries impedance analyzer. Furthermore, body composition in these young men will also be assessed using dual energy x-ray absorptiometry (DXA). The data from the impedance devices will be compared to the gold standards to assess the accuracy of estimations of total body water.
