The purpose of this study was to determine the accuracy of skeletal dimensions to estimate lean body mass (LBM). College men (n = 333) and women (n = 358) were measured for four bone diameters (biacromial, biiliac, elbow, and ankle). Skinfolds were used to estimate percent fat (%fat) and LBM from gender-specific generalized equations. Skeletal profiles were constructed from group standard values and used to predict LBM. LBM was accurately predicted (± 2.27 kg) in 31% of men and 24% of women. It was underpredicted by >4.55kg in 8% of men and 28% of women and overpredicted by 42% in men and 16% in women. Comparison of predicted %fat with %fat determined from predicted LBM was accurate (± 2%) for only 27% of men and 28% of women. Skeletal prediction of body composition in this sample was less accurate than previously reported, and care should be taken when using this method.
