Abstract
The aim of this study was to determine how several non-invasive body composition measurement techniques compared with hydrostatic underwater weighing (traditional “gold standard”) in order to determine the best options for measuring body composition in military human performance experimental field settings. Sub-cutaneous ultrasound, manual skinfolds, air-displacement plethysmography, bio-impedance, and body circumference techniques were compared. Statistical tests of agreement as well as test/re-test reliability were analyzed. Fixed and proportional biases were examined using Bland-Altman graphical analyses. Skinfolds and ultrasound were found to be the most similar to hydrostatic weighing and would be good candidates for use in military field settings. While the performance of these two methods was similar, ultrasound advantages include high preference by participants and ease of use for practitioners.
