Abstract
The purpose of this study was to compare bioelectrical impedance with hydrostatic weighing in lean subjects with varying amounts of fat-free mass and activity levels. The percentage of body fat of each subject was measured by anthropometry; bioelectrical impedance, using two different equations; and hydrostatic weighing (HW) methods. The two equations used for bioelectrical impedance were versions 1.51 (BIA2) and the weight management program (BIA3) from RJL Systems, Inc. HW was used as the criterion measure. The three groups were body builders, non-athletes, and athletes, with 10 subjects in each group. The mean value for age was 20.4 ± 1.8 years, the mean height was 70.7 ± 2.9 inches, and the mean weight was 157.5 ± 21 pounds for the subjects. The mean percentages of body fat from the present study for (BIA3), (BIA2), and HW techniques were 11.73%, 13.17%, and 8.42% respectively for all subjects. Statistical analysis revealed a significant difference (p = .0001) between the mean percentages of body fat obtained from the BIA3 and HW techniques between all subjects. There was not a significant difference between BIA3 and HW for the nonathletic group (p = .2218) and the body builders (p = .0572). There was a significant difference between BIA3 and HW for the athletic group (p = .0002). The fat-free masses determined from HW for the three groups; athletes, non-athletes and body builders; were 145.99, 130.87, and 154.77 pounds respectively. The nonathletic group had a significantly smaller amount of fat-free mass than did the athletes (p = .0476) and body builders (p = .0069). There was not a significant difference between the athletes and body builders (p = .2758). Considering the athletes were between the non-athletes and body builders for fat-free mass, but had the highest significant difference for percentage fat, it appears other factors play a role in the discrepancy between BIA3 and HW.
