본 연구는 비만아동을 대상으로 12주간 태권도 품새 수련이 비만아동들에게 어떠한 영향을 미치는 지 알아보는 것이다. 연구대상자들은 G광역시 D구에 소재한 1개 초등학교를 선정하고, 이 학교에 재학 중인 4-6학년 중 규칙적인 운동을 하지 않으며 신체검사결과 체질량지수 25kg/m2이상으로 비만으로 판정받은 남학생 24명을 선정하였다. 태권도 품새 수련군 12명, 통제군 12명을 무선배정하였다. 태권도 품새수련군은 12주간 주 3회(월, 수, 금) 오후 4~5시에 운동을 실시하였으며, 측정변인은 신체구성(체중, 체지방율), 혈중지질(TC, TG, HDL-C)과 Adiponectin을 분석하여 12주간 운동을 실시한 후 다음과 같은 연구결과를 얻을 수 있었다. 첫째, 신체구성변화에서 태권도 품새 수련군은 체중과 체지방율, 체질량지수에서 유의하게 감소하여 태권도 수련이 긍정적인 효과가 있는 것으로 나타났다. 둘째, 혈중지질의 변화에서 태권도 품새 수련군은 TC, TG, HDL-C에서 유의하게 감소하거나 증가하여 긍정적인 효과가 있는 것으로 나타났다. 셋째, Adiponectin의 변화에서 태권도 품새 수련군은 유의하게 증가하여 긍정적인 효과가 있는 것으로 나타났다.
This study aims to examine the effects of taekwondo poomsae training for 12 weeks in obese children. 24 boys in the 4th ~ 6th grades of an elementary school located in D-gu, Gwangju served as the subjects of the study. The following selection criteria were used: a student who did not take regular exercise and was judged as obese with BMI of 25 kg/㎡ or above in a physical examination.
12 children were randomly assigned to the taekowndo poomsae training group and 12 children were done to the control group. The taekwondo poomsae group was trained at 4~5 pm, three times a week(Monday, Wednesday, and Friday) for 12 weeks. Measurement factors included body composition(weight, BFP), body lipid(TC, TG, HDL-C), and adiponectin. Means(M) and standard deviation(SD) of each group were computed using SPSS(Version 17.0) program and represented by a chart. Two-way ANOVA with repeated measure was conducted to test difference between groups and between measuring times. After exercise was conducted for 12 weeks, the following results were obtained.
First, for body composition changes, the taekwondo poomsae training group showed significant decrease in weight, BFP, and BMI, suggesting positive effects of taekwondo training.
Second, for blood lipid changes, the taekwondo poomsae training group showed significant decrease in TC and TG, or increase in HDL-C, suggesting positive effects of taekwondo training.
Third, for adiponectin changes, the taekwondo poomsae training group showed significant increase, suggesting positive effects of taekwondo training.
Based on the results, regular taekwondo poomsae training decreased weight and BFP and prevented metabolic syndrome in obese children. It also decreased TC and TG and increased HDL-C and adiponectin, suggesting a positive effect to prevent cardiovascular diseases. Further study should develop a variety of exercise programs for obese children to enjoy exercise. It is considered that when steadily continuing physical activity with increased physical education activity in school, students can prevent obesity and enjoy healthy and energetic school life.
