Objective: The community has implemented a variety of exercise programs for the elderly population. However, studies comparing changes in the cardiovascular system through body composition and blood analysis after applying aqua aerobic exercise are insufficient. The purpose of this study was to investigate the effect of a 12 weeks aqua exercise on body composition and cardiovascular index in elderly women. Design: Non-equivalence pre-post design. Methods: Thirty elderly women were assigned to aquarobic group(n=15) and control group(n=15). The aquarobic exercise was 60 minutes per every session, 2times per week, for 12weeks. Weight, skeletal muscle mass, body fat percentage, total cholesterol, triglyceride, HDL cholesterol, and LDL cholesterol were measured before and after the exercise program. Paired and independent t-tests were performed using SPSS program. Results: The result showed was weight(p<0.05), body fat percentage(p<0.05), total cholesterol(p<0.05), triglyceride(p<0.05), HDL cholesterol(p<0.05), and LDL cholesterol(p<0.05) were significantly decreased and skeletal muscle mass(p>0.05) was not significantly increased after aquatic exercise program. Conclusions: According to the study result, aqua exercise program made a positive effect in the improvement of obesity and cardiovascular function in elderly women. Therefore, we suggest that you actively consider implementing the Aquarobic exercise program when operating the community health promotion program in the future. In addition, in future studies, comparative studies according to various ages and genders and studies on the effects of aqua aerobic exercise as a community exercise program for chronically illness patients are needed.

In the elderly, a lower muscle mass and higher body fat mass are induced by a lower level of physical activity. A negatively changed body composition with an advanced age can lead to a higher falling risk and rate of diseases. On the other hand, aerobic-type exercise positively influences the body composition and hyperlipidemia in the elderly. Therefore, this study examined the effects of aquarobic training for 12 weeks on the body composition and blood lipid levels in obese old women. The subjects (n = 31, body fat: 33.42%) completed a 12 week water based aerobic training at 12 - 13 of Borg Scale of intensity (three times per week, each session: an hour). The body composition was measured by bioelectrical impedance analysis (Inbody 770-Biospace, Seoul, Korea) and the concentrations of blood lipids (high-density lipids cholesterol (HDL), low-density lipids cholesterol (LDL), triglyceride (TG) total cholesterol (TC)) were determined at pre and post training. A paired t-test was used for data analysis with ${\alpha}=0.05$. In the results, the body composition (% body fat (p < 0.05) and waist circumference (p < 0.05)) were reduced significantly. The LDL (p < 0.05), TG (p < 0.001) and TC (p < 0.05) were reduced significantly. In conclusion, a 12 week aquarobic exercise program helps improve the body composition and concentrations of serum lipids. Therefore, aquarobic exercise can enhance lipolysis using fat as energy to induce an improvement of the body composition and induce hyperlipidemia.

Purpose: This study was aimed to develop and evaluate an obesity-management program for middle-aged obese women. Methods: Two 12 week session of the obesity-management programs constituted of weekly education and exercise such as aquarobic, pilates & yoga, and power-walking during 60 min for 3 days a week from June to December, 2006. The subjects included 47 middle-aged obese women between 30 and 60 yr. The effectiveness of the program was evaluated according to the change of body weight, body component, abdominal circumference, and serum lipid concentration. Data were measured by Inbody, tape measure, and blood test. Data were analyzed by descriptive statistics, and a paired t-test with an SPSS/PC. Results: There were statistically significant decreases in body weight, body mass index, body fat mass, Hemoglobin, abdominal circumference, total cholesterol level, and low density lipoprotein after the program was completed. But there were not statistically significant difference in fat free mass, muscle mass and triglyceride. Conclusion: The results of this study showed that an obesity-management program have positive effects in body composition, abdominal circumference, and lipid metabolism for middle-aged obese women.
