This study aims to examine how after-school exercise programs influenced health-related physical fitness and blood lipid in obese middle school girls. The subject of the study was students of H middle school located in G-metropolitan city. After 20 students of them who belong to the obesity which body fat percentage is above 30 were first selected, they were divided into 10 of experiment group and 10 of control group by random sampling. With the use of SPSS 17.0, the data were analyzed through technical statistics, paired sample t-test and independent sample t-test. The significance in all areas was set by ⍺=.05. The results indicate that there are two significant outcomes and the result of this were summarized as follows: 1. Body composition was analyzed in the changes in health-related physical fitness. The multiple exercise group showed a significant difference in weight(p<.001), body fat(p<.001), strength(p<.001), endurance(p<.001), flexibility(p<.01), and cardiovascular endurance(p<.05). The aerobic exercise group showed a significant difference in weight(p<.05), body fat(p<.001), and cardiovascular endurance(p<.05). 2. For the changes in blood lipid, the multiple exercise group showed a significant difference in triglycerides(p<.001) and LDL-C(p<.001), whereas no significant difference was found in TC and HDL-C. The aerobic exercise group showed a significant difference in triglycerides(p<.001). Although TC, HDL-C, and LDL-C was decreased, a statistically significant difference was not found.

Based on the results, long-time regular multiple exercise programs and aerobic exercise programs were effective to reduce obese middle school girls' weight and percent body fat to prevent their metabolic syndrome, and useful to decrease their risk for cardiovascular disease. A decrease and increase in blood lipid of multiple exercise programs also indicated positive effects on prevention against adolescents' obesity and lifestyle disease such as cardiovascular disease. Further study should develop exercise programs in order that obese middle school girls who lack in physical activity because of poor exercise hours can take regular exercise in school.
