남자 고등학생의 신체 계측치를 이용한 체지방율 추정식의 개발

Abstract

This study directly measured body parts reflecting physical characteristics of male high school students and developed a %fat estimation equation with a simple formula for objective help and high practicality. After measuring height, weight, body mass index (BMI), calf and femoral, waist circumference, waist-hip ratio (WHR), waist-height ratio (WHtR), and body mass (bio-electrical impedance) for 100 high school men, simple comparison and regression by item were performed. The subjects of the study were tested for height, weight, BMI, WHR, WHtR, femoral regions, waist circumference and bio-electrical impedance. After the measurement, the team looked for significance and correlation in each group and item to find new body mass estimation indicators that complement existing BMI disadvantages. As a result, the body fat index was produced, which can be explained 76.5% of the BMI by using a formula with a abdominal circumference and height. In addition, the estimated equation using the index from body measurements was calculated as %fat=112.258 (WHtR)-30.368 with a WHtR as an independent variant. In conclusion, the value of the abdominal circumference×BMI meant that it was more descriptive and relevant to the %fat than the BMI, which was simply the value of the weight divided by the square of the height. In the future, it is believed that the estimate of the %fat can be made by simply measuring the body with a scale and tape measure.
