The purpose of this study was to investigate the effects of aqua exercise program on body composition, blood components, and physical fitness in the elderly women. This study included 23 elderly women. The aqua exercise program was performed for fifty minutes a day, 2 times a week for 12 weeks with moderate-intensity level. Data was analyzed with SPSS using descriptive statistics and the paired t-test. The findings of this study presented that the aqua exercise program showed significant improvements in the body mass index (t=2.42, p=.024), the abdominal circumference (t=4.36, p〈.001), and the level of blood glucose (t=3.19, p=.004) and LDL cholesterol (t=3.33, p=.003). These results suggest that aqua exercise is an effective strategy which has positive effects on body composition and blood components among elderly women. It might be possible to promote health condition in elderly women by implementing aqua exercise program which could be considered aging and excercise intensity.
