The effects of varying hydration conditions on air displacement plethysmography and dual energy x-ray absorptiometry

The purpose of this study was to examine the effects of hydration on %BFADP while using %BFDEXA as the criterion measure. Twenty healthy males and females ages 20-28 participated in the study. The subjects underwent dehydration in the environmental chamber at 32°C and 50% relative humidity until a total of 3% of their body weight had been lost. Subjects were measured with ADP and DEXA at euhydration, 1%, 2%, and 3% dehydration. The results revealed significant differences between %BFADP and %BFDEXA at each level of hydration. %BFDEXA did not change due to dehydration; however, %BFADP decreased as a result of dehydration. Therefore, standardization criteria must be employed in order to assure proper hydration and accurate %BF measurements via ADP. / School of Physical Education
