ABSTRACT:
The Drinkwater-Ross anthropometric fractionation of body mass (mass summation skeletal, residual and muscle masses) and fat mass (FM) were compared with the measured body mass, together with the densitometrically estimated fat-free mass (FFM) and fat mass (FM), of 205 male (mean plus/minus S.D.: 74.66 plus/minus 10.55 kg: 10.1 plus/minus 3.7 percent BF by densitometry) and 177 female (mean plus/minus S.D.: 59.14 plus/minus 8.85 kg; 18.5 plus/minus 5.1 percent BF by densitometry) South Australian State representatives in a variety of sports. Most absolute differences (d) between the measured body masses and those resultant from the sum of the four fractionated masses (male: d = 2.15 kg or 2.9 percent; female: d = 1.27 kg or 2.2 percent) were within what one would expect from random day-to-day variation. However, this was not so for the comparisons between the fractionated LBM (male: d = 2.54 kg or 3.8 percent; female: d = 2.45 kg or 5.2 percent) and FM scores (male: d = 1.67 kg or 30.0 percent; female d = 2.40 kg or 20.0 percent) and their densitometric counterparts. These differences are probably related to a combination of the densitometric and fractionation assumptions.
