The purpose of this study was to determine the accuracy of selected anthropometric dimensions and isometric strength to estimate LBM in young adults. College men (n = 412) and women (n = 621) were measured for 4 skeletal diameters and 4 circumferences. Skinfolds estimated percent fat (%fat) and LBM from gender-specific generalized equations. Total isometric strength was determined from the sum of right and left grip, back, and leg strengths. Multiple regression produced a significant correlation (R = 0.92) to predict LBM using gender, shoulder width, hip width, and total strength. In men, the equation accurately predicted within 10% in 78% of men and 73% of women. Muscle circumferences and total strength appeared to provide a better prediction of LBM than did skeletal dimensions in both men and women. LBM tended to be overpredicted in lightweight men and women and underpredicted in heavyweight men and women.
