The objective of the research is to analyze and find out how the complex training of aerobic exercise and resistance exercise would affect the health-related physical fitness and the body shape depending on the classification of body fat rate in the case of middle-age women. To attain the objective, 24 female members in their 40s or 50s registered in a sports center in B-gu, Gwangju, were classified into two groups: the normal weight group and the obesity group. Both groups did a 70-minute training in total on a regular basis of 3 times a week for 12 weeks: 5 minutes of warm-up, 30 minutes of resistance exercise, 30 minutes of aerobic exercise, and 5 minutes of warm-down. We used SPSS Ver. 14.0 for the statistical analysis of the data, Paired Samples T-test for the comparative study of pre and post data within each group according to the training program, and Independent Samples T-Test for the difference study of the classified measurement between the groups.

1. As for the changes in physical composition, weight, BMI, lean body mass, body fat amount, and body fat rate all showed statistically meaningful difference(p<.001) in both groups. As for the difference of before and after the training session between the groups, obesity group showed slightly more reduction in weight, BMI, lean body mass, body fat amount, and body fat rate. However, there was no statistically significant difference between the two groups except for weight(p<.02).

2. Both groups showed statistically significant difference in the change of the maximum oxygen intake(p<.001), whereas the change rate between the two groups was not significantly different although obesity group showed a slight increase.

3. Both groups showed statistically significant difference in the change of grip power(p<.001), while the change rate between the two groups was not significantly different although normal weight group showed a slight increase.

4. Both groups showed statistically significant difference in the change of sit-up ability(p<.001). On the other hand, the change rate between the two groups was not significantly different although obesity group showed a slight increase.

5. Both groups showed statistically significant difference in the change of sit-up ability of bending forward from sitting(p<.001), whereas the change rate between the two groups was not significantly different although obesity group showed a slight increase.

6. As for the body shape, normal weight group ranged between the ectoderm and the mesoderm in the body shape while obesity group ranged the most between the mesoderm and the endoderm. normal weight group and obesity group all changed to the mesoderm in distribution after the training.

The study found that the health-related physical fitness and the body shape brought a affirmative effect in both groups while the variation of the change rate between the groups showed some differences in which there were no significance. As for the scale of the effect on the change rate between the groups, the study showed a big effect size in the body composition, the maximum oxygen intak, and the grip power, and a middle effect size in the sit-up, and the subjects' body shapes changed from the endoderm to the mesoderm and the ectoderm. However, since the result of the research is judged to have no great effect, it might prove the effectiveness of the training on the health-related physical fitness and the body shape more definitely if it is taken with a larger amount of subjects for a long period of time.
