Abstract

Effects of Combined Exercise and DASH Diet on Reducing Blood Sugar, Body Fat and Exogenous Stress in Obese and Diabetes Risk Groups Na, Hye-Sug Advisor : Prof. Seo, Young-Hwan Ph. D. Department of Physical Education, Graduate School of Chosun University Diabetes is a metabolic disease caused by low insulin secretion or lack of sensitivity to insulin.Additionally, because abdominal obesity increases the probability of developing diabetes by 5.8 times compared to normal weight, it means that a person who is obese and has a fasting blood sugar level at the pre-diabetes level cannot be diagnosed as diabetic, but can be classified as a diabetes risk group. The chronicity of diabetes is associated with various complications such as stroke, myocardial infarction, vascular disease, and optic nerve damage. For treatment, it is necessary to correct overall lifestyle habits, such as exercise habits and eating habits. Accordingly, the DASH (Dietary Approaches to Stop Hypertension) diet was developed by the U.S. National Institutes of Health (NIH) to prevent the rapid increase in high blood pressure and diabetes patients, and was introduced as a diet with excellent weight loss effects. Because it is based on a balanced intake of overall nutrients rather than a method of concentrating on consuming only specific nutrients that are effective for any disease, if the DASH diet is combined with exercise therapy for diabetes risk groups, it can effectively reduce blood sugar, body fat, and exogenous stress. It will be a treatment method. Therefore, this study investigated the effectiveness of combined exercise and the DASH diet in reducing blood sugar, body fat, and exogenous stress in obese diabetes risk groups, and provided guideline data for lowering the risk of diabetes and preventing the disease. The purpose is to provide. The subjects participating in the study were 22 men aged 30 to 49. There were two groups: D,G (Diet Group), which controlled their eating habits with the DASH diet provided by the researcher, and O,G (Only-exercise Group), which only exercised without controlling their eating habits. ). The criteria for subject selection were only those who met the fasting blood sugar level of 100 to 125 mg/dL and body fat percentage of 25% or more, and all subjects performed the same complex exercise. It was applied for a total of 8 weeks, and blood sugar, body fat percentage, and exogenous stress were measured pre- and post-test for comparative analysis. The exercise program consisted of compound exercise for 70 minutes per day, with one day of exercise and one day of rest every other day. The subject's data analysis was conducted using Paired samples T-test to verify changes between pre- and post-test for each group and Repeated measures ANOVA to identify the effectiveness of the dependent variable with a significance level of ɑ=.05 or less. Results 1. Changes in blood sugar Blood sugar decreased in both groups from pre to post, showing a statistically significant change (p<.001***, p<.001***). 2. Differences in blood sugar reduction effect A significant main effect difference was found in time (p<.001***) and group (p<.05*), and a significant interaction effect was found in time*group (p<.001***). 3. Changes in body fat percentage Body fat percentage decreased from pre to post in both groups, showing a statistically significant change (p<.001***, p<.001***). 4. Differences in body fat percentage reduction effect A significant main effect difference was found in time (p<.001***) and group (p<.05*), and a significant interaction effect was found in time*group (p<.001***). 5. Changes in exogenous stress Exogenous stress decreased in both groups from pre to post, showing a statistically significant change (p<.001***, p<.001***). 6. Differences in the effect of reducing exogenous stress There was a significant main effect difference between time (p<.001***) and group (p<.001***), and a significant interaction effect between time*group (p<.001***). appeared. Therefore, it was found that for the obese diabetes risk group, the DASH diet combined with complex exercise therapy was more effective at a significantly higher level than the single exercise therapy.
