A Comparative Study of Different Methods of Body Fat Assessment |
The aim of the study was to compare the results ofbody fat percentage obtained from 20 young non-obese adults with the use ofvarious selected methods: instrumental – Under Water Weigh-in (UWW) andanthropometric – Four Skinfold Measurements, Girth Measurements and BMI relatedformula, and to assess their correlation with UWW as a reference. 20 subjectswere selected from different colleges of Gwalior city. Purposive sampling wasused for selection of subjects. The age of subjects ranged from 20 to 25 years.The data collected with various methods on body fat measurement was analyzed byusing one way analysis of variance (ANOVA) and multiple range test (LSD) forsignificance of the differences among means. Product moment correlationcoefficient was used to know the correlation among selected methods of body fatmeasurement. The descriptive statistics was used for demographic information.The level of significance was set at 0.05 for the study. The analysis of datarevealed that there was a significant difference among the means of body fatpercentage measured with selected body fat measurement methods But when thePost Hoc test was applied it was found that the means of fat percentagemeasured with UWW method, Skinfold method and Girth measurement method was nothaving any significant difference at 0.05 level of significance (p>0.05).And likewise, there was insignificant difference were found in between BMImethod and Girth measurement method. When the correlation coefficient wascalculated, it was found that UWW Method for body fat measurement waspositively correlated with the other selected methods.
