The aim of this study was to investigate influence of body build on body composition, energy metabolic state and insulin concentration of blood. 29 male athletes and 36 male non-athletic students were recruited for the study. Anthropometry including chest depth and breadth, fat mass, fat fee mass, tricep skinfold thickness were measured. fasting glucose, lactate, triglyceride, fee fatty acid, and insulin concentration in serum were measured . Body build was assessed using metric index, which calculated by regression equations of Mohr and Greil. The athletic and non-athletic students were allocated to 3 body build, that is leptomorph, mesomorph, and pyknomorph. Resting metabolic rate was calculated. Respiratory quotient was determined through ratio of measured VO$_2$, and V$CO_2$. Most non-athletes have a leptomorphic body build, in contrast to athletes mesomorphic type. The body build type influenced body composition differently between non-athletic group and athletic group. Weight, body mass index, body fat mass and fat mass proportion (%), and fat-free mass increased from leptomorph to pyknormorph in non-athletic group. Pyknormorphic athletes have a significant higher body mass index, fat mass, fat free mass than other body build type. Serum glucose, triglyceride, lactate, insulin showed significant differences only in non-athletic group between leptomorph and mesomorph. RMR increased significantly from leptomorph to mesomorph in non-athletes. There was no significant difference of RQ among 3 body build types in both athletes and non-athletes. This study gives a coherent data on body build and body composition for athletes and non-athletes students. The influence of body builds on energy metabolic status of serum was different between athletes and non-athletes.
Objectives : This study examined search on how the obesity indices, that are largely used in clinics such as waist circumference(WC), body mass index(BMI) and waist-hip ratio(WHR), are related to the visceral fat that was measured from abdominal computed tomography(CT) and the ratio of visceral fat/subcutaneous fat. Then, two groups ware compared in order to find out which characteristics of ordinary adults relationship with the abdominal obesity. Two groups are divided as follows; ones who are obese based on the measurement of WC and the others who are obese based on the level of BMI. Methods : A group of 63 test subjects that were gathered in the oriental medical hospital of Kyung-Won university is divided into two groups; ones (n=51, general obesity; group A) who have $BMI{\geq}25$ and $WC{\geq}85$, and the others (n=12, abdominal obesity; group B) who have BMI<25 and $WC{\geq}85$. Then, each group's obesity indices, abdominal CT, lipid level, glucose, adiponectin, leptin and C-reactive protein(CRP) are compared. In addition, subjects are again divided into two to examine the characteristics; ones (n=14, visceral obesity; group C) with visceral obesity based on the ratio between visceral fat and subcutaneous fat measured through abdominal CT, and the others (n=38, non-visceral obesity; group D) who are obese but not viscerally obese. Results & Conclusions : As a measurement that applies abdominal visceral fat and subcutaneous fat, BMI and WC can be considered as an appropriate obesity index while WHR cannot appropriately apply the abdominal fat amount. Moreover, the study indicates that abdominal obesity group based on the ratio of visceral fat/subcutaneous fat has more significant difference than the abdominal obesity group based on the WC in case of blood lipid index.
To study the correlation with increasing body fat mass for the Standard Guideline for Korean Dietary Life, a nationwide, cross-sectional survey was performed with 178 male college students in december 2005. Among the student subjects, 76 were analyzed for body protein mass, body mineral mass, body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Body protein mass was at a high level of 92.1%, body mineral mass was at a low level of 94.7%. Body fat mass was at a high level of 28.9%, percent body fat was at a high level of 37.3%, WHR was at a high level of 31.6%, and obesity degree was at a high level of 38.2%, BMI was at a high level of 24.3% and BMR was observed at a high level of 41.8%. WHR was correlated with '7. Prepare food proper amount sanitarily.' and obesity degree, while BMl was were correlated with '4. Increase movement and eat proper amount.' positively. BMR was correlated with '6. Enjoy 3 meal a day regularly.' ArmCircle was correlated with '4. Increase movement and eat proper amount.' and fitness score was corrected with '4. Increase movement and eat proper amount', and '8. Enjoy Korean rice food style.' positively. Body protein mass and body mineral mass were negatively correlated with fruit, ArmCircle was positively correlated with fish, obesity degree was positively correlated with soup and BMI and ArmCircle were positively correlated with sweet. '8. Enjoy Korean rice food style.' was negatively significantly correlated with overweight, over percentage body fat, obesity degree > 120 and BMI. Male students were not practicing the Standard Guideline for Korean Dietary Life well with an average score of 37.7%. However, male students who are within the normal range of body composition analysis value have to notice that over range of weight, protein, percentage body fat, WHI and obesity degree was observed above average score of 30%.
This study was designed to investigate the associations of the percent body fat dietary intake, plasma lipoprotein profile, lipoprotein(a), and plasminogen activator inhibitor-1(PAI-1) concentrations of 1982 Korean subjects(men : 1000 and women : 982) between the ages of 40 and 59 years. The dietary assessment consisted of twenty-four hour dietary records and food frequency questionnaires. The subjects were identified into one of the five rating groups of % body fat : lean, underweight, normal, overweight and obese groups. The biochemical assessment included measurements of plasma total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), triglyceride(TG), lipoprotein(a)(Lp(a)), and PAI-1. With respect to the ratio of percent energy intake of carbohydrate : protein : fat of the normal group of the women was 62% : 17% : 20%, respectively. Women apparently had a higher intake of carbohydrates than men(52% : 17 : 20%) did. There was a linear relationship between energy intake and % body fat in both mean and women(with the exception of the underweight group of women). The relationship of % body fat of men to the protein and fat intake was higher than that of the carbohydrate intake. Of the men in the study, intakes of energy, protein and alcohol were positively correlated to % body fat. In women, energy, carbohydrate and protein intake were positively correlated to % body fat, however, the fat, cholesterol and alcohol intake did not show any correlation to the % body fat in women. This study showed that % body fat was positively correlated with plasma TC, LDL-C, PAI-1 levels, and TG, but the % body fat was negatively correlated with plasma HDL-C level in both men and women. These results indicated that the high energy intake of obese or overweight subjects might contribute to several of the biochemical indices fo coronary heart disease(CHD) risk. In conclusion, increased energy intake is associated with overweight or obesity in middle aged Korean people. There was no relationship between % energy intake of fat and % body fat in the study, in middle-aged Korean men and women. The plasma lipid profile and PAI-1 level thought to be the risk factors of CHD were positively associated with percent body fat in middle aged Korean people.
This study is to investigate consequent nutrient intake status, influence of body mass index(BMI), and fat distribution on the silk amino peptide(SAP) and dietary fiber supplementation. During 2 months of this research (January to March, 2002), 45 women aged 20yr – 30yr (average age 24.6yr) were selected as subjects. Nutrient intake was investigated by questionnaire, 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method(Segmental bioimpedance assay, In body 3.0). The results are as follows: mean body weight 57.7kg, mean body height 161.9cm mean BMI 22.0, and mean food habit score was 8.47. Defecation frequency was increased by dietary fiber supplementation. Frequency of pain during defecation was significantly decreased by dietary fiber supplementation (p<0.01). Feeling of residual feces was significantly improved by dietary fiber supplementation(p<0.001). Status of energy and carbohydrate intakes significantly decreased after dietary fiber supplementation(P<0.05). Body fat and WHR(waist hip ratio) significantly decreased after dietary fiber supplementation(P<0.001), and percent body fat was decreased by dietary fiber supplementation, significantly(P<0.05). Above results of this study show that dietary fiber-added routine diet improves defecation condition, and lessens body fat, percent body fat without losing body muscle. Especially, declination of abdominal fat and WHR were notable. That meant decreased risk factor.
Objectives: Considering that homeothermy is a major component of metabolic rate, body temperature might play a role in the pathophysiology of obesity. This study aimed to determine the relationship between abdominal fat distribution and abdominal temperature in Korean, premenopausal, obese women. Methods: Weight and height were measured in 26 premenopausal, obese women to calculate body mass index (BMI). Obesity was defined as a $BMI{\geq}25kg/m^2$. Waist circumference (WC) was also measured as well as abdominal fat by computed tomography (CT) and abdominal temperature by digital infrared thermographic imaging (DITI). Results: Visceral abdominal fat area was found to have a significant negative correlation with the temperature of Guanyuan (CV4, lower abdomen acupoint). We also found the visceral-subcutaneous fat ratio had a significant negative correlation with the temperature of CV4 and Right Tianshu (RST25, lateral navel acupoint). Only visceral fat and its ratio to subcutaneous fat had a significant correlation with abdominal temperature. Subcutaneous fat area and total fat area were not correlated with abdominal temperature. Conclusions: This study suggests that abdominal visceral fat has a significant negative correlation with abdominal temperature. Further study is needed to uncover the relationship between abdominal fat distribution and temperature regulation in obese individuals and to define the role of body temperature in the pathogenesis of obesity.
Purpose: Dysmenorrhea is a women's common disease. The aim of this study is to investigate the relation between body composition and VAS, VRS, MVRS of dysmenorrhea. Methods: The subject were 17 women who took body composition(body mass index, percent body fat, waist-hip ratio) analysis(Inbody 720) and answered the questionnaire have been calculated VAS, VRS and MVRS in Kangnam Korean Hospital, Kyunghee Univ. from Apr. 6, 2007 to Mar. 25, 2007. Results: There was statistically significant correlation between BMI and dysmenorrhea VRS, MVRS. There was statistically significant correlation between BMI and dysmenorrhea VRS, MVRS. There was statistically significant correlation between percent body fat and dysmenorrhea VRS, MVRS. There was statistically significant difference of dysmenorrhea VRS, MVRS between BMI underweight group and BMI normal or overweight group. There was statistically significant difference of dysmenorrhea VAS between waist-hip ratio normal group and waist-hip ratio abnormal group. Conclusion: Body composition analysis(body mass index, percent body fat, waist-hip ratio) is useful to predict pain grade of dysmenorrhea.
Objectives: This study was conducted to evaluate efficacy and safety of Punica granatum L. Actinidia chinensis Planch. mixed extract on body fat. Methods: Thirty women were recruited ($25kg/m^2{\leq}body$ mass index [BMI]${\leq}29.9kg/m^2$) ($19yr{\leq}age{\leq}38yr$) and randomized to receive Punica granatum L. Actinidia chinensis Planch. mixed extract or placebo for 8 weeks. During the test, they visited four times including screening. Body fat mass, body fat rate, anthropometric dimensions at waist and hip, waist-hip ratio, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C) were measured at screening and 8 weeks after screening. Adverse reaction were also checked each visit. Results: There were no significant differences in all index. But when divide experimental group by BMI index, age, and compliance, less than BMI $27kg/m^2$ group decreased body weight, body fat mass and more than BMI $27kg/m^2$ group also decreased body weight, body fat mass and waist circumference. Less than age 30 years group showed decline of waist circumference, fat free rate and T-cholesterol and more than age 30 years group showed decline of fat free mass. Group with compliance more than 95% was decreased BMI, fat free mass, and hip circumference. Conclusions: There was no significant efficacy as compared with placebo group, but as divide experimental group according to BMI index, age, compliance, mixed extract might be effective to reduce obesity index.
Formulas for the prediction of total body fat from skinfold thickness in middle aged men were presented. Hydrostatic weighing was made on 35 middle-aged men $(age:\;40{\sim}50\;years)$ sad corrected for residual volume in lung. Skinfold thickness at four sites, namely, arm, back, waist and abdomen were compared with total fat calculated from the formula given by Keys and Brozek and regression equations were derived. In middle-aged men the observed values were: Body density, 1.07478 ; total body fat, 10.51% body weight; lean body mass, 89.49% body weight; arm skinfold thickness, 4.85mm; back, 10.4 ; waist, 7.72; abdomen, 7.62 and mean skinfold thickness of the four sites, 7.59 mm. The correlations between skinfold thickness and body density were high. The correlations between skinfold thickness and total body fat were also high. The coefficient of correlation between total body fat and arm skinfold, mean skinfold thickness were r=0.839 and r=0.862, respectively. Arm and mean skinfold thicknesses (x, mm) could be used as the representative value for the prediction of total body fat (y, % body weight). The regression equations were: On arm y=2.00x+0.99, With mean skinfold y=1.20x+1.41 The coefficient of correlation between body weight (kg) and mean skinfold thickness was r=0.733. The ratio of mean skinfold thickness (mm) to body weight (kg) in middle-aged men was 0.132.

Anti-obesity effect of a new dietary supplement (3D-relax) in high-fat fed rats. The aim of this study was to assess the effects of 3D-relax; a proprietary formulation containing hydroxycitrate (233 mg/g), carnitine (150 mg/g) and red pepper (150 mg/g); on body weight, body fat, and serum lipids levels in rats fed a high-fat diet. Male SD 7-wk-old rats (n=8) were fed a high fat diet [52% total dietary energy (E%) from fat, 15.4 E% protein, 32.6E% carbohydrate] with or without 3D-relax administration (1 g/kg body weight/day) for 3 weeks. Administration of 3D-relax significantly reduced the increase in body weight compared to the group fed high fat without 3D-relax. Food efficiency ratio (FER) tended to be decreased with administration of 3D-relax, but was not significant. The perirenal and epididymal fat pad weights of vats administered 3D-relax were significantly lower than those of the high fat group that did not ingest 3D-relax during the 3 weeks. The oral administration of 3D-relax significantly increased HDL-cholesterol level and lowered total cholesterol level compared to those of high fat alone group. These results suggest that 3D-relax reduced body weight and fat gains, and those effects are presumably linked to its inhibitory effects on lipogenesis.
