This study was conducted to investigate the effectiveness of a nutrition and exercise education program on weight control of adult women. The subjects of this study were 28 adult women aged 20-59 years residing in the Daegu area. The nutrition-exercise educational period was 12 weeks. The collected data consisted of items on general characteristics, anthropometric data, blood biochemical values, physical strength data, dietary behavior and nutrition knowledge scores of the subjects. During the 12 weeks of weight control, body mass index(BMI), % of body fat, body fat mass and waist-hip ratio significantly decreased. The level of plasma triglyceride decreased, but not significantly. The level of total cholesterol did not change compared to baseline before the program. After the weight control program, back muscle strength, sit-ups, push-ups, and sit-and-reach tests of the subjects significantly improved. The nutrition knowledge scores of the subjects significantly increased. Therefore, these results suggest that the nutrition-exercise education program may contribute effectively to weight reduction with improvement of physical strength in adult women.

The purpose of this study was to compare the anthropometry, the serum lipid levels and the nutrient intakes of two groups according to their alcohol intake, smoking habits, regular exercise patterns, menopause status and obesity levels. The subjects consisted of 180 clinically normal adults (males 89, females 91) in the Youngdong area. There were significant differences in the triglyceride (TG) concentrations between the alcohol consumers (169.3 \pm 130.0 mg/dl) and the non-alcohol consumers (111.4 \pm 64.5 mg/dl), and the smokers (165.0 \pm 103.6 mg/dl) and the non-smokers (110.8 \pm 39.0 mg/dl). Although regular exercise did not affect the serum lipid levels, the dietary intakes of cholesterol, niacin and phosphate were significantly higher (p<0.05) in the male exercising group than in the male non-exercising group, and female exercising group consumed more polyunsaturated fatty acids (p<0.05) than the female non-exercising group. The waist/hip ratio. serum total cholesterol (198.4 \pm 36.3 mg/dl) and serum LDL-cholesterol (119.5 \pm 34.9 mg/dl) levels of the postmenopausal females were significantly higher than those of the premenopausal females (p<0.01). The obese males showed higher serum cholesterol, LDL-cholesterol, LDL/HDL, and relative cholesterol levels than those of the normal-weight males : and the obese females showed higher serum TG levels than that of the normal-weight females (p<0.01). These results suggested that drinking, smoking, menopause and obesity are risk factors for hyperlipidemia. Thus, moderation in alcohol consumption, non-smoking, regular exercise and the maintenance of normal weight are necessary to Prevent hyperlipidemia in middle-aged People.

This study was an attempt to compare the energy, nutrient intake, blood lipids, and body fat distribution of diabetics with those of normal control subjects. Daily energy and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participants : weight, height, and waist and hip circumference. We matched 31 pairs with diabetics and nondiabetic control subjects by sex, age, body weight and height, and made comparisons between two groups to observe the effect of diabetes in lipid profiles. Aslo the effect of exercise in diabetes was investigated. The results obtained were as follows : 1.The average of daily energy intake of diabetics was 1, 927 kcal and that of nondiabetics was 2, 159 kcal. Percentage of energy in diabetics is that carbohydrate : protein : fat = 69:13:18 2. When diabetics were divided into obese and nonobese group according to RBW, 33% of diabetics were obese and energy intake was not significantly different between the two groups, but VLDL - cholesterol concentration was significantly higher in the obese group. 3. Energy intake, BMI, RBW and total cholesterol level of upper obesity group were significantly higher than those of lower body obesity group in male diabetic subjects. 4. When matching 31 pairs of diabetics and nondiabetics according to sex, age, body weight and height triglyceride concentration and WHR of diabetics were measured to be significantly higher than those of nondiabetics. 5. Although energy intake was not significantly different between exercise and nonexercise groups, triglyceride, blood glucose, RBW, BMI were significantly lower in the exercise and nonexercise groups, triglyceride, blood glucose, RBW, BMI were significantly lower in the exercise group than the nonexercis group in diabetics. 6. BMI and RBW were not correlated with cholesterol or triglyceride, but WHR correlated significantly with both cholesterol and triglyceride. In conclusion, diabetics had higher triglyceride concentration and WHR than nondiabetics. WHR may be better than BMI or RBW for predicting alteration in lipid profile and exercise seems beneficial for controlling blood glucose and lipids in diabetics.

Background : Cardiopulmonary exercise test is a useful test for the evaluation of the cardiovascular and respiratory systems. Obese subjects have an increased resting metabolic rate ($VO_2$) compared to non~obese subjects and the increase is more marked during dynamic exercise, which results in the limitation of maximal exercise in obese subjects. In this study, the influence of the obesity and fat distribution on the maximal exercise capacity were evaluated. Methods : Maximal exercise capacity was represented by maximam maximum oxygen uptake and $VO_2$ max in the cardiopulmonary test. Obesity, total fat content and abdomina1 obesity(waist to hip ratio, WHR) were measured by bioelectrical impedence method. Total of 42 volunteers (male 22, fema1e 20) were evaluated. Results : 1) Weight to height ratio (mean$\pm$SD) was 110$\pm$14.9% in men and 100$\pm$11.1% in women. 2) Fat ratio (mean$\pm$SD) was 23.3$\pm$5.2% in men and 27.55$\pm$3.9% in woman. 3) Waist to hip ratio (mean$\pm$SD) was 0.85$\pm$0.04 in men and 0.8$\pm$0.03 in woman. 4) In men, $VO_2$ max/min/Kg was negatively correlated with obesity, fat ratio, and abdominal fat distribution. 5) In woman, $VO_2$ max/Kg was negatively correlated with obesity and fat ratio, but did not show significant relationship with abdominal fat distribution. Conclusion : Obesity was a limiting factor for maximal exercise in both men and women. Abdominal obesity was a limiting factor for maximal exercise in men but its implication to women needs further evaluation.

The purpose of this study is to analyze the level of obesity and sarcopenia among chronic obstructive pulmonary disease(COPD) patients in Korea. The current study recruited 75 patients with COPD who visited the department of respiratory medicine at J University Hospital in J-do. Height, body weight, waist circumference, and hip circumference were measured, and body composition, muscle strength, and flexibility were assessed. The levels of obesity were classified with body mass index(BMI), waist-hip circumference ratio(WHR) and percent body fat, and sarcopenia was classified with the value of skeletal muscle mass and muscle strength by Asian Working Group for Sarcopenia. In results, it was found that the level of obesity was very high as 43% by BMI, 88% by WHR, and 64% by percent body fat. The lower level of muscle strength was 15.50% in males and 23.50% in females. The lower level of muscle mass was 24.10% in males and .00% in females. Males who had one sarcopenia factors were 22.40%, and females were 23.50%, respectively. Males with sarcopenia were 6.90%, and females were .00%. In conclusion, regular resistance exercise is essential not only for the development of motor skills, but also for the normalization of skeletal muscle function and prevention of muscle dystrophy among COPD patients.

The purpose of this study is searching for technical merits and demerits of each weight lifting player through qualitative motion analysis system. Moreover, It is also analysis the repeating the establishment of exercise purpose and studying for the effect of the field adaptation. The subject of this study was five male weight lifting players who have been engaged in Korean Delegation Team. The institution of exercise target was made through two times qualitative analysis and the result of studying for the effect of the field adaptation was produced before offering feedback. Moreover, two time analysis added after offering feedback. All analysis was based on 2-D visual analysis. The results of this study are as follows: 1. Maximal barbell moving speed in starting phase was decreased after offering feedback. This result implies advancement of technical skills after offering feedback. 2. From starting posture to 앉아받기, forward and backward moving distance of hip joint was decreased after offering feedback in all subjects. This result represents advancement of technical skills after offering feedback. 3. In terms of pull phase, forward and backward moving distance of hip and shoulder joint was decreased after offering feedback in all subjects. This result represents advancement of technical skills after offering feedback. 4. In terms of pull phase, the difference of horizontal value of coordinates was decreased after offering feedback in all subjects. This result represents advancement of technical skills after offering feedback. 5. In terms of pull phase, the motion range of hip joint was decreased after offering feedback in three of five subjects and this represents advancement of technical skills after offering feedback. However, the rest of them were not variable or narrow decreasing. This result represents that feedback system could not brought tremendous effects. 6. From apex point of barbell to 앉아받기, the difference of barbell height was decreased after offering feedback in three of five subjects and this represents advancement of technical skills after offering feedback. However, the rest of them weren't variable or narrow increasing. This result represents that feedback system could not brought tremendous effects. 7. In terms of last-pull phase, the angular velocity of knee joint was increased after offering feedback in four of five subjects and this represents advancement of technical skills after offering feedback. However, the rest of them, only one subject, decreased. This result represents that feedback system could not brought tremendous effects. 8. In terms of last-pull, the conversional tendency of maximal extension to flextion came out all but simultaneously without offering feedback in four of five subjects. This is well-performed technique. Only one subject, however, could not use power effectively because the fact that his maximal extension came out in serial, from ankle to knee and waist means dispersion of power. In addition to, after offering feedback, only one subject made increasing the maximal extension of knee in last-pull and this result represents advancement of skills after offering feedback. However, the rest of them could not make meaningful development after offering feedback. 9. It might be assumed that searching for technical merits and demerits of each weight lifting player through qualitative motion analysis system could improve player's skill.
