The purpose of this study was to determine whether the assumed density
and composition of the FFM, and estimates of %Fat from body density
using the Siri equation (%Fatd) are valid in weight trainers with
high musculoskeletal development. Measures of body density by
underwater weighing (Db), body water by deuterium dilution, and bone
mineral by whole-body dual-energy X-ray absorptiometry were obtained
in young white men, 14 weight trainers with high musculoskeletal
development and 14 non-weight-training controls with average
musculoskeletal development. %Fatd was significantly higher (p
