This study concluded the followings by analysing the changes on the rate of body fat and blood lipids of elderly women after types of the aquatic exercise for 8 weeks to find out how it effect elderly women. First, swimming groups and aquarobics groups shows no difference in changing the rate of body fat. Second, swimming groups and aquarobics groups shows an effect on total cholesterol, low density lipoprotein cholesterol and triglyceride but no effect on high density lipoprotein cholesterol. Third, it also showed no difference between swimming groups and aquarobics groups. Overall, the participated in swimming and aquarobics for 8weeks showed a positive effect on total cholesterol, low density lipoprotein cholesterol and triglyceride of elderly women, although there were no changes in the rate of body fat and high density lipoprotein cholesterol. Also, the effect of types of the aquatic exercise showed lost on the rate of body fat and blood lipids of elderly women. These results are considered to be caused by the common benefits of significant reduction in the body weight by using the buoyance of the water, shock absorbing effect of water, and exercise using water resistance. Thus, it is expected to be a great help in health promotion and maintenance of elderly women if the types of the aquatic exercise is accomplished continuously for a long time in the future.
