This study investigated the effect of 12 weeks combined exercise and nutrition education program on body composition, liver function, serum lipids and insulin resistance in obese middle-aged women. The combined exercise program was performed for 55 minutes 3 times per week during which the intensity progressively increased from RPE 13 to 14, 60-70%HRR (1~5 weeks), RPE 15 to 17, 70-80% HRR (6~12 weeks) and nutrition education was conducted 20 minutes one day per week. The subjects were 21 obese middle-aged women were composed of the nutrition education group (A, n=7), combined exercise group (B, n=7), and the control group (C, n=7). The results of the study in the nutrition education group and combined exercise group were as follows; The A and B group had significantly lower body composition than did the control group. The A group had significantly lower liver function, TC, TG, HDL-C, and HOMA-IR than did the control group. Consequently, combined exercise and nutrition education program effective in preventing diabetes caused by obesity in obese middle-aged woman. On the basis of the results of this study, the following recommendations are made for further studies: additional studies are needed to confirm the results of this study and to compare the effects of combined exercise on these variables in obese and non-obese men and women by age or exercise type; they are also needed to develop effective nutrition education programs for different age groups or body types.
