트레드밀 걷기운동과 수중운동 병행이 비만중년여성의 체력과 혈중지질에 미치는 영향

This study was conducted with 22 obese middle-aged women with percent body fat of 30 or higher by dividing them into the exercise group(n＝12) and the control group(n＝10). The purpose was to examine the effects of walking and aquatic exercise conducted simultaneously with the exercise group for 12 weeks, 4 times per week(Monday, Tuesday, Thursday, Friday) on health-related physical fitness and blood lipid. The effects of exercise were compared and analyzed and finally, the following conclusion was drawn. First, the walking and aquatic exercise program had positive effects on the change in health-related physical exercise in obese middle-aged women: Muscle strength(p<.01), muscular endurance(p<.001), flexibility(p<.01), cardio-respiratory endurance(p<.05), and body composition(weight, p<.001; % body fat(p<.001; lean body mass(p<.001), and BMI(p<.001)). Second, the walking and aquatic exercise program had positive effects on the change in blood lipid in obese middle-aged women(TG, p<.01; HDL-C; p<.05, LDL-C and p<.001). There was no significant difference in measurement period for TC and the control group had no significant difference. Based on this result, the walking and aquatic exercise program was found to decrease weight and body fat, improve health-related physical fitness, and influence blood lipid positively in obese middle-aged women. Accordingly, it can be recommended as an effective program for obese middle-aged women. Also, if exercise strength is gradually increased, more apparent effect may occur. Further study should make efforts to generalize study results by increasing study participants. Furthermore, since several other factors such as dietary life and life habits can work, it should be sufficiently considered to control the study subject.
