In Korea, metabolic diseases are increasingly growing due to increase in visceral fat caused by severe obesity. In particular, obese middle-aged women are at high risk of obesity-related diseases because of the lack of physical activity, calorie overintake, and the lack of exercise. Although many previous researches have been reported by applying exercise programs to obese middle-aged women, there are few researches have been conducted using an aquarobics program. Thus, this study aims to analyze the effects of an aquarobics program on body composition, blood lipids, and inflammatory markers in obese middle-aged women and provide multilateral basic materials for exercise in middle-aged women. 30 obese middle-aged women with more than 30% body fat were explained the period of study, methods, and effectiveness and their informed consents were obtained. They were divided into the exercise group(n=11) and the control group(n=11). The exercise group took part in the aquarobics program for 60 minutes, 3 times per week. Blood examination was conducted before and after the program and the effects of program on body composition, blood lipids, and inflammatory markers were compared and analyzed. As a result of 12-week aquarobics program, it was found that body composition was significantly reduced in weight(p<.001), BMI(p<.001), and % body fat(p<.001), suggesting a positive effect of aquarobics program on body composition in obese middle-aged women. Blood lipids were found to be significantly different in TC(p<.05), TG(p<.01), and LDL-C(p<.001). Although HDL-C showed no significant difference in time, significant difference was shown in group × time(p<.01). Adiponectin showed significant Adiponectin(p<.01). The control group showed no significant difference in all factors. The aquarobics program was effective for reducing weight, BMI, and % body fat which may prevent metabolic diseases in obese middle-aged women, and also helpful for decreasing blood lipids which may cause cardiovascular diseases. In particular, which demonstrates that it can be a useful exercise program to reduce onset risk of cardiovascular diseases. The fact that weight loss after the aquarobics program led to increase in Adiponectin secreted from obese cell suggests the possibility to inhibit inflammation in obese patients. As aquarobics do not overstrain joints, it can be strongly recommended for obese middle-aged women.
