This study was aimed at .reveling how stamina and body composition through swimming sports affects middle-aged women for 12 weeks. Divided into 20 (in exercise group(10) and control group(10) ), older women took part in swimming exercise program for 12 weeks and conducted exercise three times a week. Before and after experiment, we measured subjects' stamina and body composition twice. From the results, we carried out correspondence samples t-test for significant difference verification in groups and independent sample t-test between groups. Level of significance was established with p<05 . Then, we come to the following conclusion.

1. The body fat in change of body composition was decreased after experiment(p<.01), and there was not significant difference statistically between groups before and after measurement. 2. After experiment, change of physical fitness in exercise group showed significant difference of muscle strength ,muscle endurance, cardiovascular endurance , explosive muscular strength (p<.05, p<.01, p<.001), and change of physical fitness in control group before and after experiment showed significant difference statistically in terms of all factors.

Taken together, swimming sports formed conclusions that there was a positive effect. on the body composition (Body fat ratio) and stamina (muscle strength Muscular endurance, cardiovascular endurance and explosive muscular strength ) we failed to control external factors such as diet and lifestyle but if in further research intensity of exercise ,exercise frequency programs take concrete form, it will be considered good research base line data for improving physical constitution and great physical strength of middle-aged women.
