Skeletal Dimensions to Predict Lean Body Mass in College Men and Women

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.
