It has been shown that both caloric restriction and exercise, enhances glucose uptake through translocation of GLUT-4 protein. It remains unclear how exercise and caloric restriction affect the changes in VAMP (vesicle-associated membrane protein) in skeletal muscle and GLUT-2 in liver. This study investigated the effects of exercise training and caloric restriction on the expressions of glucose transport relating proteins in muscle and liver tissues in diabetic rats. Forty male Sprague-Dawley rats (250±10 g; 8 week in age) were assigned equally to four different groups; control (C), exercise only (E), dietary restriction only (D) and dietary restriction and exercise (DE). Daily food consumption was monitored to establish baseline intake. Both C and E groups consumed baseline food intake while D and DE groups were provided with only 60% of baseline total food intake. Forty-eight hours after intraperitoneal injection of STZ (50 mg/kg), diabetes was confirmed (8-hr fasting blood glucose levels ≥300 mg/dl). Rats in the E and DE groups exercised on a motorized treadmill for 30 min/d, 5 days/week for 4 weeks (5 min running at 3 m/min, 0% grade; 8 m/min for the next 5min, and then 15 m/min for 20 min). Rats were sacrificed 48 hrs after the last bout of exercise. Soleus muscle and liver were extracted to analyze for GLUT-4, VAMP-2, and GLUT-2, respectively. All variables were analyzed using the Western Blotting technique. All values were expressed as optical volume measured by optical density. A Two-way ANOVA was used to examine the difference between groups and applied Duncan's test for post-hoc. No significant differences in GLUT-2 expression were found among groups. However, E (280133±13228 arbitrary units{AU}) and DE (268833±14424 AU) groups showed significantly higher (p<.001) levels of GLUT-4 as compared with C (34461±2099 AU) and D groups (27847±703 AU). VAMP-2 protein expression increased (p<.001) in E (184137±7803 AU) and DE (189800±10856 AU) groups as compared to C (74201±8296AU) and D (72967±863 AU) groups. These results suggest that either exercise with or without caloric restriction increases the up-regulation of GLUT-4 and VAMP-2 in skeletal muscle of diabetic rats. However, GLUT-2 protein in liver was not affected by either exercise or exercise with caloric restriction.
The purpose of this study was to investigate to the effect of regular exercise on nutrients intakes and energy balance related to food habit and nutrient knowledge of college women. This study was conducted from May to June in 2000. One hundred and forty female students made their three day dietary records by 24-hr recall method and one day activity record. The questionaires were designed to fine out food habit and nutrition knowledge status. The height. weight and blood pressure were measured and also body fat mass and lean body mass measurements were performed. The results obtained are summerized as follows. Average height and weight of E(exercise) group were found to be increased than those of NE(non-exercise) group. The percent of body fat and body fat mass(kg) in E group were slightly lower than those of NE group. Calorie intake of NE group was 1,664kca1 per day. This was composed of carbohydrate 60%kcal. protein 14%local and fat 24%local. Calorie, calcium, iron, vitamin A, vitamin B$_2$ and niacin intakes of NE group were lower than those of RDA and calorie intake of E group was 2.313kca1 per day. This was composed of carbohydrate 54%, protein 13% and fat 31%. Other nutrients such as iron, vitamin A, niacin and vitamin C were lower than those of RDA. Daily energy expenditure and physical activity of E group were 2,397.6$\pm$49.2kca1; 1,035.7 $\pm$36.5kcal, respectively and it was higher than those of NE group.
[Purpose] The purpose of this study was to examine the effects of elastic band exercises and nutritional education, as well as to identify the factors influencing frailty, strength, and nutritional intake of elderly women. [Methods] The subjects in this study were 30 elderly women who were divided into four groups. All groups agreed to participate in four programs: health education only (HE), elastic band exercises only (EX), nutritional education only (NU), and elastic band exercises plus nutritional education (EX+NU). Frailty was evaluated by measuring the frailty factors according to Fried et al. Leg strength was measured using a leg-extension machine. Nutritional intake was assessed by the 24-hour recall method and food records. Nutritional intake was analyzed by CAN Pro 5.0 program. [Results] After three months, the prevalence of frailty significantly decreased in the EX+NU group (P=0.013) compared with that of the HE group (P=0.088). There was significant improvement in leg strength in both the EX (P=0.012) and EX+NU groups (P=0.003) compared with that of the HE group (EX, P=0.005; EX+NU, P=0.002). The nutritional intake significantly decreased in the EX group compared with that of the HE group (P<0.05, P<0.05). [Conclusion] The combination of elastic exercises and nutrition education had positive effects on frailty and leg strength, while having negative effects on total calories, carbohydrate, sodium, and iron intake in elderly women. Elastic exercises only had positive effects on leg strength while having negative effects on nutritional intake in elderly women.
The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.
This study was designed to investigate the dietary habits, life habits, physical symptoms, and body composition of male and female students attending college in incheon, based on which to encourage proper dietary habits among and enhance the physical and psychological health of college students. The effects of personal characteristics (such as gender, grade level, residence type, means of transportation), health relative life habits (exercise, smoking and alcohol consumption), dietary habits, physical symptoms and body composition measurement were analyzed by using the questionnaire and Inbody. The subject pool was composed of 96 male and 149 female students. Smoking, drinking, exercise, and fruit intake showed significant differences between the genders (p<0.05), whereas meat intake was not significantly different (p>0.05). Differences on dietary habits and the intake of fruit showed significant differences (p<0.05) between the genders. Especially, more female than male students showed a higher frequency of fruit intake. Physical symptoms such as headache, common cold, dizziness, easy fatigue, poor concentration, indigestion and constipation showed significant differences (p<0.05) between the genders, whereas stomatitis, anorexia and pale face were not significantly different (p>0.05). Differences between the genders on body composition, height, weight, BMI, muscle soft lean mass, body fat mass, skeletal muscle mass and waist-hip ratio were also significantly different (p<0.05). The correlation analysis of college students by gender was negative between intake of milk and physical symptoms (p<0.01), whereas intake of cooked food and physical symptoms showed a positive correlation (p<0.01, p<0.05).
This study examined the effect of various types of exercise on bone formation and resorption in rat. Five-week-old male Sprague-Daweley rats were randomly assigned to one of four groups with 10 animals in each; Control, Treadmill, Swimming, Resistance. The exercise regimen consisted of treadmill running at 25m/min, 1 hr per day, 5 days a week, and swimming for 1 hr per day, 5 days a week. Resistant exercise type with weight-bearing was designed to extend lower and upper extremities in order to feed the diet and water. Food intake showed no significant difference among groups but body weight gain and food efficiency were significantly increased in Control group as compared with exercise groups. Femur and tibia length and weight were higher in Control group and the density of therm tended to be higher in exercise groups than Control group, but this difference was not statistically significant. The breaking force of femur was the highest in Swimming group and tibia was the highest in Resistance group among groups, while there was no signigicant difference among the exercise groups. The calcium content of femur was significantly increased in Resistance group than the other groups. Calcium intake and urinary calcium showed no significant difference among groups, while calcium absorption and retention were significantly higher in exercise group than Control group. In conclusion, exercise training enhanced bone formation due to the positive effect on metabolism of calcium and bone which were different according to the types of exercise.

Food-dependent exercise-induced anaphylaxis (FDEIAn) is induced by different types and various intensities of physical activity, and is distinct from food allergies. It has been shown that consumption of allergenic food followed by exercise causes FDEIAn symptoms. Intake of allergenic food or medication before exercise is a major predisposing factor for FDEIAn. Urticaria and severe allergic reactions are general symptoms of FDEIAn. Dermatological tests and serum IgE assays are the typical prescreening methods, and have been used for several decades. However, these screening tests are not sufficient for detecting or preventing FDEIAn. It has been found that exercise may stimulate the release of mediators from IgE-dependent mast cells that can result in FDEIAn when a certain threshold level has been exceeded. Mast cell degradation might be a major factor to induce FDEIAn but this has not been determined. A number of foods have been reported to be involved in the onset of FDEIAn including wheat, eggs, chicken, shrimp, shellfish, nuts, fruits, and vegetables. It is also known that aspirin increases the occurrence of type I allergy symptoms when combined with specific foods. Moreover, high intensity and frequent exercise are more likely to provoke an attack than low intensity and less frequent exercise. In this paper, we present the current views of the pathophysiological mechanisms underlying FDEIAn within the context of exercise immunology. We also present a detailed FDEIAn definition along with etiologic factors and medical treatment for cholinergic urticaria (UC) and exercise-induced anaphylaxis (EIA).
This study was conducted to find the effect of in-class nutrition education and exercise program for obese adolescent boys in Taegu with the nutrition knowledge test before and after education program and anthropometric measurement. The subjects were consisted of a normal group (NG; n= 13) and an obese group (n=30). The obese group is divided into two groups; obese group A (OG-A; n=12), participated in a ten-week nutrition education only; and obese group B (OG-B; n=28), participated in a ten-week nutrition education and exercise program. The anthropometric data of the three groups were increased after the nutrition education program. However the obesity index(BMI, R hrer, WHR, Skinfold thickness) of OG-B were significantly decreased after the programs. The nutrition intake data were also changed after the nutrition education program. Especially the intake of carbohydrate was significantly decreased in OG-B from $421.5{\pm}155.9g$ to $349.0{\pm}41.0g$ (p<0.05) after the nutrition education program. It was noted that the intake of Ca was significantly decreased in all three groups after the nutrition education program. The mean score of the nutrition knowledge test also significantly increased from $13.7{\pm}3.1$ to $17.8{\pm}3.0$ after the nutrition education program. The result strongly suggested that nutrition education program should be successful if the obese adolescents and their parents especially mothers participated in the same class. In summary, nutrition education and exercise programs were effective on reducing obesity of obese adolescents. Nutrition knowledge of obese adolescent was significantly increased after nutrition education program.
This study was conducted to investigate the relationship among prevalence of obesity, nutritional status and factors related to obesity of women who exercise regularly. The subjects of this study were 100 women who have been exercising regularly for more than 6 months. They were mostly housewives ages 24 to 63 years and had graduated middle or high school. Their average income was form 700 to 1,500 thousand won per month and most of them had 2 r 3 children. They sleep usually 6~8 hours a day. Most of physical indices of obesity were increased progressively with age. Among them , weight (61.5$\pm$1.4kg), subscapular (16.3$\pm$1.4mm) and abdomen(31.4$\pm$1.2mm) skinfold thickness were higher in 50 years than in others. BMI after exericse was decreased compared with BMI before exericise. WHR was 0.82 in 40 years and 0.85$\pm$0.01 in 50- to 60- year-old group. The percentage of body fat increased with advancing years and the highest values were shown in 50 - to 60-year old group (skyndex value : 38.6$\pm$0.6, BIA value : 28.7$\pm$0.8<0.05). The prevalence of obesity was measured by bioelectrical impedance fatness analyzer (BIA), obdy mass index (BMI) and skinfold thickness were 17.0%, 24.0% and 78.0% respectively. Most subjects were in good nutritional status, but in the subjects aged 24~49, energy (89.3%), iron (93.3%) and vit. A (97.4%) intake were slighltyl lower than the RDA. Energy intake was slightly insufficient tot he 50-63year old subjects (88.6%) compared with RDA. It seemed that they restricted calorie intake for the weight control. The energy percentage of carbohydrate, fat and protein was 65 : 20 : 15, the result of which came closed to the recommended calorei composition. There were positive correlations between obesity and other variable such as age. number of childeren and physical indics.
This survey was carried out to obtain the information concerning nutritional status, including factors of food intake and health condition of elderly living in Ulsan area. Main results were as follows. 1) Average height of subjects was close to Korean reference, while weight was below Korean reference, average obesity rate and body mass index were +6.93% and 21.9. 2) In health related factors, 41% of subjects exercised regularly, 31.6% of subjects drank alcoholic beverage, and 41.4% of subjects smoked currently. 3) Mean food habits score was 32.1(ranging from 10 to 50) and milk and lipid food intake were decreased. 4) Dietary intake data showed the average daily intake of all nutrients except phosphorus, were lower than RDA, especially vitamin A, calcium and zinc were lower than other nutrients. According to the percentage of RDA, vitamin A was the nutrient found to be least sufficient. 5) Among the various influential factors resident type, pocket money, exercise and smoking influenced on nutrient intake considerably
