| Abstract |
This study has been written to compare and analyze middle aged obese women's body composition and blood lipid by walking that is representative of aerobic exercise. The middle aged obese women live in K dong, G si and have 25~30 kg/m2 range of BMI. The walking is enforced in a 300m track playground of K elementary school, G si, Kyoung-ki do from 6:30 PM to 8:00 PM. A leader let them take 20 turns by a target heart rate which is based on personal intensity of exercise (60~70%HRmax). The exercise is enforced three times a week (Mon, Wed, Fri) for 12 weeks. It is under consideration that the middle aged obese women do not have experience of exercise. The average value and standard deviation is deduced by SPSS Ver 12.0. The significant differences in group is deduced by 'Paired t-test' and in range P<0.5, the significance is inspected. There are conclusions. First, there is 1% significant difference at BMI and weight when an author analyze body composition which is compared before exercising with after exercising. However there is no significant differences at an amount of muscles and lean body mass. Second, there is 5% significant difference at total cholesterol when an author analyze blood lipid which is compared before exercising with after exercising. Also there is 1% significant difference at triglyceride. But there are no differences between HDL-C and LDLC. To conclude, regular walking gives middle aged obese women positive effects at blood such as reducing BMI weight, total cholesterol and triglyceride. The other side, there are not much significant differences at an amount of muscles, lean body mass and HDL-C and LDL-C. It might be the walking is low intensity exercise and period of exercising was short. Thus to keep exercising continually and strengthen intensity of exercise would be needed. Also to try various events during long period would be needed. |
