TI  - Effect of race and musculoskeletal development on the accuracy of air 
      plethysmography.
PG  - 1070-7
AB  - PURPOSE: The purpose of this study was to determine the effect of race and 
      musculoskeletal development on the accuracy of estimates of body fatness (%fat) 
      via air displacement plethysmography (AP). METHODS: Estimates of %fat were made 
      via AP, hydrostatic weighing (HW), dual-energy x-ray absorptiometry (DXA), and 
      the criterion, a four-component model (4C) in 64 black (B) and white (W) men, who 
      were either resistance trained (RT) or served as controls (C). RESULTS: Based on 
      a three-way ANOVA, there were no statistically significant three-way or race x 
      musculoskeletal development interactions. There was no main effect of race on the 
      validity of estimating %fat by AP; the mean bias between %FatAP and %Fat4C was 
      similar for B (3.6% body fat) and W (3.7%). In addition, the density of the 
      fat-free mass (Dffm) for B (1.098 +/- 0.002 g x mL) was not different than 1.10 g 
      x mL. There was a significant effect of musculoskeletal development on the 
      validity of the estimation of %fat from AP; the mean difference in %fat between 
      %FatAP and %Fat4C was less in RT (1.5% body fat) than in C (5.3%), but a large 
      SEE of 5.5% was observed for RT. A significant (P < 0.05) correlation was found 
      between the mean bias between methods and body volume (-0.44) and mesomorphy 
      (-0.55). CONCLUSIONS: Race does not affect the accuracy of estimating %fat by AP. 
      Race-specific equations estimating %fat via densitometry (e.g., AP, HW) such as 
      the Schutte are not justified, because Dffm is not greater than 1.10 g x mL. 
      Estimation of %fat via AP is more accurate in larger individuals with high 
      musculoskeletal development as a group, but individual results are highly 
      variable.
