10주간 달리기 운동이 비만 여중생의 신체구성, 인슐린 및 렙틴 농도에 미치는 효과를 규명하기 위하여 1∼5주 동안은 50∼60% HRmax, 6∼10주 동안은 61∼70% HRmax의 강도로 주당 4회, 1회에 30∼40분씩 달리기 운동을 실시하여 운동 전·후 변인들의 측정치를 비교 분석한 결과, 신체구성의 변화에 있어서는 운동집단의 경우 체중은 4.17㎏(p<0.05), 체지방율은 4.14%(p<0.01), WHR은 0.07(P<0.01), 지방량은 3.1㎏(p<0.01) 유의한 감소를 나타냈다. 그리고 인슐린 농도의 변화는 운동집단에서 15.75μIU/㎖(p<0.01), 렙틴 농도의 변화는 운동집단에서 7.16ng/㎖(p<0.01) 감소를 보였다. 한편, 상관성에서는 운동집단에서 10주 운동 전 렙틴 농도는 인슐린 농도(r=0.75, p<0.05), 체지방율(r=0.92, p<0.05), WHR(r=0.78, p<0.05), 지방량(r=0.76, p<0.05)과 유의하게 높은 상관성을 보이고 있었는데, 10주간 운동을 실시한 후에도 이들 변인들간은 높은 상관성이 유지되면서 변화되는 양상을 보였다. 이상에서 살펴본 바와 같이 달리기 운동이 신체구성, 인슐린 및 렙틴 농도에 유의한 변화를 가져 왔으므로, 규칙적인 달리기운동은 기초대사와 지방분해 능력 및 제지방조직, 에너지 소비율, 지방질 이용의 증가를 통해 신체구성, 인슐린 및 렙틴 농도에 긍정적인 효과를 미치는 것으로 나타났다.

The aims of this study were to investigate the change of the body composition(body weight, % fat, fat mass, WHR), insulin, leptin and correlation between related variables. In this study, running(HRmax 50∼70%, 30∼40mins/day, 4days/week) was performed and 18 obese girl students(control group; n=9, running group; n=9) were participated for 10 weeks. Independent and Paired t-test was used to evaluate the difference of the pre and post treatment, between groups. And Pearson Correlation Coefficients was used to investigate any correlation between related variables. The 0.05 level of significance was as critical level for this study. The result of this study were as following ; 1. Body composition, body weight(4.17㎏, p<0.05), % fat(4.14%, p<0.01), WHR(0.07, P<0.01) fat mass(3.1㎏, p<0.01), were decreased significantly after running of 10 weeks. 2. The concentration of insulin(15.75 μ IU/㎖, p<0.01) was decreased significantly after running of 10 weeks. 3. The concentration of leptin(7.16ng/㎖, p<0.01) was decreased significantly after running of 10 weeks. 4. The correlation between leptin and insulin, %fat, fat mass, WHR was significantly correlated before running. And this correlation was also maintained after running of 10 weeks. These results suggest that on body composition, insulin and leptin in running for 10 weeks affects obese middle girl students. On the other hand, long term regular running influenced in body composition, insulin and leptin for increase of BMR, Lipolysis, utilization of fat.
