The research titled “Comparison of two different methods of measuring body composition” tested two methods of body composition assessment to compare of measurement and the accuracy of each one of them for similarity of results. Skinfold (SF) measurements and bioelectrical impedance analysis (BIA) were used to collect information and then the numbers were compared using statistical analysis. Measured was percent body fat, lean mass, and fat mass in 20 college aged males and females. There was a significant difference between SF and BIA for all the three variables; lean mass, fat mass, and percent body fat. The paired samples t-test revealed a significance-value of 0.008 for lean mass and fat mass, and a p-value of 0.016 for percent body fat. Percent differences varied among each subset of measurement. Lean mass had a percent difference of 4.713%, fat mass with a difference of 14.253%, and finally percent body fat of 12.578%. Fat mass showed the largest variability, potentially caused by several factors. These factors could potentially include the inherent variability in location of SF measurements and the potential for error that hydration status can have on BIA results. Although the results between SF and BIA were significantly different, the differences in mean measurements weren’t extremely different from a practical perspective. Both methods of body composition analysis are valid tools for measuring fat mass, lean mass, and percent body fat.
