이 논문의 목적은 대사증후군 청소년을 대상으로 12주간의 태권도 수련을 실시하여 대사증후군 위험지표, 혈청 지질, 최대산소섭취량의 변화를 연구하는데 있다. 대상자는 대사증후군 청소년 30명을 태권도 수련군 15명, 대조군 15명 무선배치 하였다. 태권도 수련은 평균 운동강도 HRR 60~70%로1회 60분, 주 5회, 12주간 실시하였으며 다음과 같은 결과를 나타내었다. 태권도 수련군에서 제지방량, 허리와 엉덩이 둘레 비율, 그리고 최대산소섭취량이 그룹과 시기간의 상호작용에서 유의한 차이가 나타났으며 대사증후군 위험지표들에 있어서는 허리둘레, 중성지방, HDL 콜레스테롤과 수축기 혈압이 그룹과 시기간의 상호작용에서 유의한 차이가 나타났다. 또한 최대산소섭취능력에 따른 대사증후군 위험지표들의 수준을 비교해본 결과 최대산소섭취 능력이 낮은 그룹보다 높은 그룹에서 대사증후군 위험지표들의 수준이 HDL 콜레스테롤은 높게 나왔으며 나머지 인자들은 낮은 것으로 나타났으며 특히 허리둘레, 혈당, 중성지방과 HDL 콜레스테롤은 그룹 간에 유의한 차이를 나타내었다. 따라서 규칙적인 태권도 수련은 대사증후군 청소년들의 신체구성과 최대산소섭취능력의 향상과 대사증후군 위험지표 개선에 긍정적인 영향을 준 것으로 나타났으며 특히 높은 최대산소섭취능력은 대사증후군 위험지표와도 밀접한 관련이 있는 것으로 나타났다. 그러므로 대사증후군 청소년들은 심폐체력을 향상시킬 수 있는 태권도 수련과 같은 규칙적인 운동을 반드시 실시하여야 하며 이는 대사증후군을 예방하고 개선하는데 도움을 줄 수 있을 것이라 사료된다. The study aims to examine the changes in relative risk of the metabolic syndrome, plasma lipid levels, and maximal oxygen uptake by performing a 12 weeks taekwondo training targeting adolescents with the metabolic syndrome. The subjects were 30 adolescents with the metabolic syndrome, and they were randomly assigned with 15 taekwondo training group members and 15 person control group members. Taekwondo training performed five times a week for 60 minutes of each time, and the results of test with the average exercise intensity HRR 60~70% for 12 weeks. The results were as follows. In the taekwondo training group, there was a significant difference in lean body mass, the ratio of waist and hip, and the interactions between the group and time in terms of the maximal oxygen uptake. As to relative risks of the metabolic syndrome, waist circumference, triglycerides, HDL-cholesterol, and systolic pressure showed a significant difference in interactions between the group and time. In addition, as the result of comparing the level of relative risks of the metabolic syndrome according to maximal oxygen uptake, the level of relative risks of the metabolic syndrome was excellent in the group with higher maximal oxygen uptake, and especially there was a significant difference between groups in terms of waist circumference, glucose, triglycerides, and HDL-cholesterol. Therefore, the regular taekwondo training had a positive impact on improvement body composition and maximal oxygen uptake in adolescents with metabolic syndrome as well as reduction in relative risks of the metabolic syndrome. In particular, the excellent maximal oxygen uptake was closely related to the relative risks of the metabolic syndrome. Accordingly, adolescents with the metabolic syndrome should exercise like taekwondo to improve their cardiopulmonary fitness, and it will be helpful to prevent and improve the metabolic syndrome.
