Purpose : The purpose of this study is to verify the effectiveness of combined marine healing programs by analyzing the physical composition of metabolic patients, blood lipids and the effects of the inflammatory factors, the C -reactive protein(CRP). Methods : the combined marine treatment program was conducted for 6 hours a day, 5 days a week on the 10 adult patients with metabolic diseases and the results of their body composition, blood lipids and CRP were analyzed before and after the subjects completed the program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20 and a paired t-test was conducted in order to test for the differences before and after the combined marine treatment program. All significant levels were set to 𝛼=.05. As a result of the experiment Results : First, regarding the changes in body composition and blood pressure after the 5-day combined marine treatment program was completed, there were statistically significant differences found in weight (p<.01) and systolic blood pressure (p<.05). Second, regarding the changes in blood lipids and CRP after the program was conducted, there were statistically significant differences found in total cholesterol (p<.05) while there was no statistically significant difference found in the variables of neutral fat, low-density lipoprotein cholesterol and CRP. Conclusion : the study results were integrated, the 5-day combined marine treatment program had a positive effect on weight, blood pressure and total cholesterol in the patients with metabolic diseases. Therefore, the short-term marine treatment program was thought to be effective for them. However, considering no significant differences were found in neutral fat, low-density lipoprotein cholesterol and CRP, further development and research on combined marine treatment programs should be conducted in the long term to create an effective program for patients with metabolic diseases.

The study was performed to investigate the effects of whey protein-rich meal substitute added with vitamins, minerals, and lactobacillus powder probiotics on weight loss, body fat, and body composition in 24 female volunteers for 4 weeks. Whey protein-rich meal substitute was consumed with low-fat, high calcium milk (1% fat, 260 mg/200 mL) twice a day. Subjects submitted 3-day diet records and a life-style questionnaire before the study. During the study, subjects were required to turn in a diet record every day and consume the meal substitute formula in the metabolic ward at C university for 4 weeks. Anthropometric measurements were carried out weekly by Inbody 7.0. The dietary intake and anthropometric data were analyzed to compare changes before and after the study by paired t-test with SPSS version 23.0. The subjects were mostly early 20's and either overweight or obese and highly motivated to lose weight. Most of the subjects consumed three meals per day regularly and spent mostly 10~15 minutes for a meal. Their caloric intake was relatively low and decreased from 1,360 kcal at week 0 to 1,100 kcal after 4 weeks. However, total protein intake increased while carbohydrate and fat intakes decreased (p<0.05) after the trial. Nine vitamin intakes after the study improved compared to those before the study (p<0.05). After the study, subjects showed lower body weight (-1.8 kg), body fat (-0.94 kg), percent body fat (-0.86%), as well as waist circumference (-4.52 cm), hip circumference (-0.44 cm), waist hip ratio (-0.05), and triceps skinfold thickness (-2.39 mm) compared to those at week 0 (p<0.05). Muscle mass tended to be less compared to week 0, although there was no significant differences between weeks 0 and 4. In conclusion, diet trial with whey protein-rich meal substitute induced weight loss and positively changed body fat parameters and body composition.

The purpose of this study was to determine changes in body composition and blood lipids and to analyze the effects of Danhak exercise for 3 months in older women. For this study, 35 female subjects 60 to 70 years of age were recruited and administered 90 min of Danhak exercise, five times per week for three months by a professional coach. The results of this study were as follows: At baseline, the mean BMI(body mass index) and body fat(%) were 23.9 kg/$(m)^2$ and 32.4$\pm$4.9(%), respectively. The mean WHR(waist-hip ratio) was 0.91$\pm$0.04 and all subjects were determined to be abdominally obese. A significantly lower body fat was observed after 3 months of Danhak exercise(p<0.05). However, there were no significant differences in BMI, WHR or body weight before and after exercise. Danhak exercise also resulted in a decrease in total cholesterol and an increase in HDL(high density lipoprotein, and these differences were significant. Taken together, the results of this study indicate that the effects of Danhak exercise were similar to those of aerobic exercise with respect to improve body fat(%) and blood lipid profiles, which suggests that Danhak is a profitable exercise for individuals aged 60 and over.

A 4-week energy balance study was conducted to estimate the energy expenditure (EE) of 16 college age men and women, 20 to 26 year of age, by measurement of energy intakes and changes in body energy(BE) content(intake/balance technique), keeping their normal living pattern and maintenance body weight. Energy intake was measured by bomb calorimetry and estimated by food table. Fecal energy loss was calculated from nitrogen excreted. Fat mass was determined from body density estimated from skinfold tickness. 1) Gross energy (GE) intakes calculated from food table was not only 13.4% lower than those of bomb calorimetry but also lower 4 and 5% than metabolizable energy(ME) intakes for the male and female subjects, respectively. 2) Fecal energy loss was 7.2% and 6.9% proportion of the gross energy intake for the male and female subjects, respectively. 3) Mean daily metabolizable energy intakes estimated by subtract fecal and urinary energy loss was 2467kcal for the male subjects and 1897kcal for the female subjects. 4) Total body energy change estimated from body composition change over 31 days was decreased 7672kcal for the male subjects and 2689kcal for the female subjects. 5) Mean daily energy expenditure was 2714kcal (45kcal/kg of body weight) for the male subjects and 1984kcal(40kcal/kg of body weight) for the female subjects. 6) The estimated energy expenditure of college-age subjects in this study provide evidence to support the Recommended Dietary Allowances for energy of Korean normal adult.
