걷기운동이 비만어린이의 혈장 성장호르몬과 IGF-1 농도에 미치는 영향 = Effect of Walking Exercise on Plasma Growth Hormone and Insulin-Like Growth factor-1 in Obese Children

다국어 초록 (Multilingual Abstract)

The purpose of this study was to verify the effects of exercise by analyzing the changes of body composition, plasma insulin, GH, and IGF-1 in the 6th grade of elementary school obese boys following walking exercise for 12 weeks. The subjects were over 30% of body fat obese children. twenty-four subjects were grouped into experimental group(n=12) that participated in the program of walking exercise and comparative group(n=12) that had no treatment. The subjects exercised at 55-65% HRmax for an hour per day, 3 times in a week. Independent t-test was used to compare the two groups. Paired t-test was used for the comparison of pre and post-exercise. In the experimental group body composition, body weight, BMI and %body fat were reduced. In constituent parts of the blood serum insulin was reduced whereas, GH and IGF-1 were increased. It was concluded that walking exercise reduces the risk factors in cardiovascular disease and prevents obesity in adults with the fact that walking exercise in obese children changes the body weight, body composition, %body fat, insulin, GH and IGF-1 into positive state.
