Objectives: The purpose of this study was to compare the effects of a 8-week compound exercise and a home-based walking exercise on body composition, perceived health status, and stress of nursing students. Methods: A non-equivalent control group design with pre-post test was employed. Participants, having BMI below 23 and Percent Body Fat above 26%, were assigned to three groups; 21 for the compound exercise(A), 26 for the walking exercise(B), and 23 for the control group. For data analysis, ANOVA in SPSS was used. Results: Body Fat Mass(kg), Visceral Fat Area(cm2), and Percent Body Fat(%) of both group A and B were significantly decreased. Lean Body Mass(kg) and Fitness Score of both group A and B were significantly increased in comparing with the control group. Especially the score of PBF(%) in group A was significantly decreased than the group B. The perceived physical health status in both group A and B was significantly increased. Conclusion: Both 8-week compound exercise and walking exercise were effective in enhancing BFM(kg), VFA($cm^2$), PBF(%), LBM(kg), Fitness Score and perceived physical health status. Especially the Compound exercise program was much more effective in decreasing PBF(%) than the walking exercise program.

Purpose: The purpose of this study was to examine the effect of a 8-week dynamic yoga program on body composition and blood lipids in middle-aged post-menopausal women. Method: Twenty participants were allocated to the yoga group (YG, n=10) or the control group (CG, n=10). They were assessed for lean body mass, percent body fat, waist to hip ratio, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and triglyceride both before and after intervention. The yoga group participated in the program lasting $50{\sim}60$ minutes, five times a week for 8 weeks. Results: Unlike the control group, the yoga group showed a significant decrease in total cholesterol, low density lipoprotein cholesterol, percent body fat, and waist hip ratio after the yoga training. However, changes in lean body mass, high density lipoprotein cholesterol, and triglyceride level during the intervention period were not different between the yoga group and the control group. Conclusion: The 8-week dynamic yoga program could be adopted to prevent cardiovascular diseases in middle-aged post-menopausal women by promoting body composition & blood lipids.

This study was conducted to investigate the relationship between maximum oxygen uptake and its related factors including body measurement and vascular compliance. The subjects of our study were 43 males and 53 females aged 40 to 59 who were visited in military health center. The main results were that 1.the degree of obesity had significantly negative correlation to vascular compliance in male, and waist-hip ratio in female. 2. The degree of obesity, body mass index, waist-hip ratio and body fat percent had significantly negative correlation to maximum oxygen uptake in male, and waist-hip ratio & body fat percent in female. 3. Maximum heart rate had significantly positive correlation to maximum oxygen uptake in male, and vascular compliance & maximum heart rate in female. 4. In multiple regression analysis which maximum oxygen uptake was as dependent variable, body fat percent, vascular compliance and maximum heart rate were significant variables for both male and female. In conclusion, Maximum oxygen uptake of some rural people age 40 to 59 were affected by various factors such as body fat percent, vascular compliance, and maximum heart rate.

The purpose of this study was to evaluate nutrient and food intake status and dietary, quality according to obesity based on nutrient and food group intake, in female university students. Surveys were conducted using questionnaires and 3 days, dietary record in 360 female university students residing in Seoul. The subjects were divided into two groups by percent of body fat: an overweight group(percent of body fat more than 23%, n=249) and normal group(percent of body fat below 23%, n=111). The overweight group had a larger proportion of subjects who binged compared to the normal group. There was no significant difference in energy intake between the two groups. The densities of plant calcium and dietary fiber in the overweight group were significantly lower than those of the normal group. However, animal fat density was significantly higher in overweight subjects. The Korean's dietary diversity score(KDDS) of the overweight group was 4.65, and that of the normal group was 4.67, indicating no significant difference. There was no significant difference of DQI-I between the overweight group(50.8) and normal group(51.1). However, the macronutrient ratio score was significantly lower in the overweight group. These results indicate that overweight female college students may have improper dietary habits, and have lower overall balance aspect macronutrient ratios.

BACKGROUND/OBJECTIVES: We aimed to investigate the association of waist circumference (WC) with body composition among individuals with a normal body mass index (BMI) to distinguish muscle and fat mass, as both affect health differently. SUBJECTS/METHODS: We analyzed dual-energy X-ray absorptiometry data (derived from the Korean National Health and Nutrition Survey, which includes information on fat and lean mass) of 7,493 adults with a normal BMI. Subjects were categorized into four groups of increasing WC. The fourth group was defined as being centrally obese. Each number of subjects are as follows: 1,870, 695, 231, and 39 among men and 3,054, 1,100, 406, and 98 among women. We conducted a sex-stratified linear regression analysis of body composition according to WC group after adjustments for covariates. RESULTS: We observed a positive association of body fat with increasing WC in both men and women (all P for trend: < 0.001). The adjusted mean values for percent body fat with 95% confidence intervals (CIs) according to the four WC groups in ascending order were 17.8 (17.5-18.3), 21.0 (20.6-21.5), 22.1 (21.5-22.8), and 25.1 (24.2-26.1) in men and 29.7 (29.4-30.0), 32.0 (31.6-32.3), 32.9 (32.4-33.4), and 34.7 (33.2-36.1) in women. However, there was an inverted J-shaped association between muscle mass and WC. The fourth group had a higher percent body fat and lower muscle mass than other groups. The adjusted mean values for appendicular skeletal muscle mass index (kg/m²) with 95% CIs according to the four WC groups in ascending order were 7.55 (7.51-7.59), 7.62 (7.56-7.68), 7.65 (7.56-7.74), and 7.22 (7.04-7.41) in men and 5.83 (5.80-5.85), 5.96 (5.92-6.00), 6.03 (5.96-6.10), and 5.88 (5.73-6.03). CONCLUSIONS: There was a positive association between body fat and WC among individuals with normal BMI; conversely there was an inverted J-shaped association between lean body mass and WC. Our findings support the WC measurement should be included in obesity evaluations for adults with a normal BMI.

This study was conducted to investigate the relationships among the levels of fasting serum insulin, free fatty acid, lipids and anthropometry in normal-weight female college students. Serum insulin and free fatty acid levels were negatively correlated. However, insulin, triglyceride, and cholesterol levels were not correlated with fat mass or BMI(body mass index). The ability of anthropometric and biochemical indicators to predict fatness could be important for epidemiologic and clinical research. In the subjects, waist cirumference was correlated with BMI, fat mass and percent body fat, and HDLC/CHOL (high density lipoprotein cholesterol/cholesterol)was correlated with body weight, BMI, and fat mass. Our data suggests than waist circumference and HDLC/CHOL are predictors of fatness, whereas WHR apears to be a less important contributor to fatness in female college students.

This study was designed to evaluate Saturday nutrition classes for obese elementary students in Chungnam Province. Obesity index, nutrient intake, nutrition knowledge, nutrition attitude, and self-satisfaction of 36 obese elementary students were compared before and after attending nutrition classes every other Saturday for 3 months. The average age, height, weight, body fat, % body fat, and obesity index were 11.9 years, 145.5 cm, 53.3 kg, 24.5 kg, 45.7%, and 32.4%, respectively. Most of the subjects(94.5%) viewed themselves as fat. Sixty-three percent of children were discontent with their body-image. All answered that they have experience with weight control. The major methods of weight control were exercise and reduction of snacks. The mean serum cholesterol, blood glucose, GOT/GPT, and hemoglobin were 177.4 mg/dL, 90.4 mg/dL, 25.8/25.5 IU/L, 14.5 g/dL, respectively. After attending nutrition classes, the daily intakes of energy, plant protein, plant fat, carbohydrate, crude fiber, and cholesterol increased significantly. The scores for nutrition knowledge, nutrition attitude, and self-satisfaction also increased after nutrition classes, but there were no significant differences. Percent body fat decreased significantly after nutrition classes. In conclusion, nutrition education for elementary students is effective for the prevention and control of obesity. Further research is needed to develop a systematic program of nutrition education for obese children.

The aim of this study was to investigate the combined effects of aerobic training and diacylglycerol ingestion on lipid profiles and resting metabolic rate changes in obese men. The subjects were divided into 3 groups: the Diacylglycerol group (D, n=6), aerobic training group (E, n=6), and diacylglycerol ingestion and aerobic training group (DE, n=6). Diacylglycerol was ingested and aerobic exercise training performed for 12 weeks. The information from the research was calculated through a Windows SPSS/PC+ Ver. 12.0K statistics package to standardize the means and deviations for each group. Then, two-way repeated measures ANOVA was used to evaluate the research hypothesis. Percent body fat, blood lipid profiles and resting metabolic rate changes were tested to evaluate the combined effect of aerobic exercise training and diacylglycerol ingestion. The results of this study were as follows; DG ingestion was shown to have a positive effect on body weight and body fat, while having a negative effect on resting metabolic rate changes. However, aerobic training was shown to have a positive effect on all factors including body weight, body fat, and resting metabolic rate. In conclusion, DG ingestion and exercise training were not shown to have synergistic effects on resting metabolic rate changes, percent body fat and lipid profiles, while aerobic exercise training was shown to have a positive effect on resting metabolic rate changes, percent body fat, and lipid profiles. To investigate the therapeutic effect of DG ingestion and aerobic exercise for obese men, analysis of catecholamine, cAMP, HSL, or insulin sensitivity should be considered.

Body fat proportion is a major issue in health. The prevalence of obesity in childhood has been increasing on thesedays. A series of indirect estimates of body fat have been developed. There are hydrodensitometry, BIA and anthropometry equation for body fat. Hydrodensitometry has been regarded as a common criterion method. BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. The purpose of this unvestigation were to compare body fat and other body composition between boys & girls and to know which anthropometry equation for body fat was most closely associated with BIA in boys & girls respectively. The subjects were 148 4th grade elementary school students(male:70, female:78). They underwent BIA(InBody 3.0, Biospace Korea)to determine body fat and other body composition. Anthropometric measurements were taken of height, weight, skinfolds and circumferences. The results obtained are summarized as follow: 1) Weight, BMI and Rohrer index were $39.9{\pm}7.2kg$, $20.5{\pm}8.0$, $138.2{\pm}17.0$ for boys and $35.9{\pm}6.7kg$, $18.2{\pm}2.6$, $96.6{\pm}13.6$ for girls. 2) Total body fat and percent body fat determined by BIA were $10.3{\pm}4.3kg$, $25.4{\pm}6.6%$ for the boys group and $9.3{\pm}3.8kg$, $25.1{\pm}6.0%$ for girls. 3) Mean triceps skinfold thickness was $20.5{\pm}6.1mm$ in boys, $17.0{\pm}5.1mm$ in girls and mean WHR was $0.88{\pm}0.4$ in bodys, $0.82{\pm}0.4$ in female and the values were significantly different by sex. 4) Correlational nanlyses showed that estimation of body fat by BIA measurement seemed to be closely associated with Rohere index(boys r=0.854, girls r=0.909). Kim's equation was highly correlated with the body fat in girls(r=0.910) but less correlated in boys(r=0.710). We need to develop specific anthropometric equations based on age and sex to determine body fat for children.
