Purpose: The purpose of this study was to identify the effects of taekwon aerobic on obesity indices and cardiovascular risk factors in middle-aged obese women. Method: Data were collected from 19 middle-aged obese women who participated in taekwon aerobic exercise. This research adopted one-group pretest-posttest design. Taekwon aerobic was applied 3 times in a week for 12 weeks, and the obesity indices and cardiovascular risk factors were checked before and after the program. Body weight, BMI and % body fat for obesity indices were checked, and total cholesterol, triglyceride, HDL-cholesterol and the ratio of total cholesterol/HDL-cholesterol for cardiovascular risk factors were measured. The data was analyzed by paired t-test using SPSS/win 10.0. Results: There were significant differences in body weight, BMI and % body fat after the taekwon aerobic exercise. There was a significant difference in total cholesterol. However, there were no significant differences in triglyceride, HDL-cholesterol and the ratio of total cholesterol/HDL-cholesterol after the taekwon aerobic exercise. Conclusion: This study showed that taekwon aerobic exercise decreased obesity indices and lowered total cholesterol in the cardiovascular risk factors. The results of this study show that taekwon aerobic exercise is effective in enhancing the health of middle-aged obese women.
