초음파 측정기를 이용한 20대 남성 체지방률 추정식 개발

Abstract

Purpose: The purpose of this study is to develop an equation for estimating body fat percentage for men in their twenties using an ultrasonic measuring device.<BR> Method: The percentage of body fat was measured on male students in their 20s in Gyeonggi-do. For the development of the estimation formula according to the internal cross-validity procedure, 105 subjects were divided into 70 in the estimation-type development group and 35 in the cross-validity test group. The regression formula development exploration and validity analysis were conducted.<BR> Results: As a result of the analysis, the coefficient of determination was 82% and the standard error was 3.2% in the estimation formula at the development stage. In cross-validity, the estimated body fat percentage did not differ from the measured body fat percentage (p=.660), and the coefficient of determination was 94% and the total error was 2.2%. The final estimation formula that synthesized all the research results was y=2.245+1.125x.<BR> Conclusion: In conclusion, the validity of the body fat ratio estimation formula developed based on the ultrasonic measuring device is verified. When this formula is applied to men in their 20s in Korea, it is confirmed that it is suitable for the individual together with the group.
