Different techniques in assessing body composition among inactive adolescent female

The purpose of this study is to evaluate the differences between three body composition techniques which are SKF3 sites and SKF4 sites, and BIA (Inbody Biospace 230 model) in the determination of percentage of body fatness in inactive adolescent between 21–25 years old.24 females adolescent who are inactive become a subject in the evaluation of different techniques in body composition. Subjects were randomly selected according to their daily activities and their ages were between 21–25 years. There is a significant difference between BIA, SKF3 and SKF4 in which p=0.00; p value was set at <0.05 using Sample t -Test. There is a correlation between the three techniques. BIA and SKF3 has a correlation of (r = 0.567), BIA and SKF4 has a correlation of (r = 0. 574) and strong correlation exist between SKF3 and SKF4 (r = 0. 931). Even though BIA shows immediate results in assessing fat percentage, but it has high standard error estimation (SEE 1.64%) compare to SKF3 and SKF4. (SEE 0.32%). Present study shows that SKF3 and SKF4 site have a high accuracy in measuring body fat percentage and no significance differences in fat percentage results between them among inactive adolescent.
