  • Objective: The aim of this study was to investigate the correlation coefficients between anthropometric parameters of the foot and kinetic variables during running. Method: This study was conducted on 21 healthy young adults (age: $24.8{\pm}2.1yes$, height: $177.2{\pm}5.8cm$, body mass: $73.3{\pm}7.3kg$, foot length: $256.5{\pm}12.3mm$) with normal foot type and heel strike running. To measure the anthropometric parameters, radiographs were taken on the frontal and sagittal planes, and determined the length and width of each segment and the navicular height. Barefoot running was performed at a preferred velocity ($3.0{\pm}0.2m/s$) and a fixed velocity (4.0 m/s) on treadmill (Bertec, USA) in order to measure the kinetic variables. The vertical impact peak force, the vertical active peak force, the braking peak force, the propulsion peak force, the vertical force at mid-stance (vertical ground reaction when the foot is fully landed in mid-stance or at the point where the weight was uniformly distributed on the foot) and the impact loading rate were calculated. Pearson's correlation coefficient was used to investigate the relationship between anthropometric variables and kinetical variables. The significance level was set to ${\alpha}=.05$. Results: At the preferred velocity running, the runner with longer forefoot had lower active force (r=-.448, p=.041) than the runner with short forefoot. At the fixed velocity, as the navicular height increases, the vertical force at full landing moment increases (r= .671, p= .001) and as the rearfoot length increases, the impact loading rate decreases (r=- .469, p= .032). Conclusion: There was a statistically significant difference in the length of fore-foot and rearfoot, and navicular height. Therefore it was conclude that anthropometric properties need to be considered in the foot study. It was expected that the relationship between anthropometric parameters and kinetical variables of foot during running can be used as scientific criteria and data in various fields including performance, injury and equipment development.

  • We aimed to evaluate the effect of nutrition education program on nutrition knowledge, dietary behavior, dietary intakes and anthropometric parameters in primary school children. Eighty five 4th grade children (boys = 43, girls = 42) were enrolled in the intervention program for 5 months. The subjects were asked to fill out a questionnaire about nutrition knowledge and dietary behavior two times, at the baseline and after completion of the program. Dietary intake information was collected from participants using a 3-day food record and their anthropometric parameters were measured. Upon completion of the intervention program, both nutrition knowledge and dietary behavior scores were significantly improved in all subjects. Energy intake was increased from 1,571.9 kcal to 1,734.1 kcal with significant improvements in nutrient density for protein, Ca, P, K, vitamin A and niacin. While subjects' height, weight, lean body mass and soft lean mass were significantly increased during the program, significant decreases were observed in the rohrer index, percent body fat, waist-hip ratio and body fat mass. The changes in nutrition knowledge scores were positively correlated with the changes in dietary behavior scores, micronutrient intakes and anthropometric parameters. These results indicate that enhancement of nutrition knowledge through well-planned long-term nutrition education program is effective not only for the improvement of dietary behaviors and dietary intakes but also for the positive changes in anthropometric parameters among primary school children.

  • BACKGROUND/OBJECTIVES: The aim of this study was to evaluate the sensory properties of antioxidant-rich bread made by adding pomegranate peels and their effects on anthropometric measurements and metabolic and oxidative parameters of individuals with type 2 diabetes after consumption. SUBJECTS/METHODS: This randomized, double-blind, placebo-controlled study was conducted with 22 individuals aged between 19 and 64 years who had been diagnosed with type 2 diabetes for at least 5 years, used only metformin, did not lose more than 10% of their body weight in the last 6 months, and had a body mass index of ≥ 25.0 kg/m2. While the study group (n = 11) consumed bread containing 500 mg pomegranate peel daily for 8 wk, the control group (n = 11) consumed standard bread. Anthropometric measurements and metabolic and oxidative parameters of individuals were evaluated at the beginning and end of the study. RESULTS: Decreases were detected in the waist circumference, waist/hip and waist/height ratios, body fat percentages, blood pressure, and serum insulin, triglyceride, and total cholesterol levels in the individuals in the treatment group, compared with those in the control group (P < 0.05). CONCLUSIONS: Pomegranate peel consumption by individuals with type 2 diabetes may have positive effects on anthropometric measurements and glycemic and lipid parameters.

  • In this paper, we propose a methodology of generating a parametric segment model for human body using the Korean anthropometric data. The model is defined as an articulated body model consisted with 19 ellipsoid primitives. The primitives are joined at locations representing the physical joints of human body. A lot of previous researches have suggested methodologies of generating body models using the European or American anthropometric data, so that these models were inappropriate for engineering analyses and simulations in case of the Koreans. We defined a set of 35 body dimensions representing our segment model based on the anthropometric data of Koreans. Also we defined four key parameters of age, height, weight and waist circumference, and then we applied regression equations to associate the parameters to the aforementioned dimensions. As the results, we obtained the parametric human body segment models according to the various body types and the subject-specific models for a specific individual. The models in the various industries can be used as the base models for static and dynamic analysis considering the Koreans.

  • Objectives To investigate correlation between anthropometric data (neck circumference (NC), waist circumference (WC), body mass index (BMI), and body shape indexes) and radiological parameters of lumbosacrum. Methods The data of college students living in Seoul (n=24) were analyzed retrospectively. Anthropometric data of NC, WC, and BMI were measured. Lumbar spine X-ray film was taken to measure lumbar lordotic angle, Ferguson's angle. To evaluate body shape of participants, three indexes of neck-to-waist ratio (NWR), neck-to-height ratio (NHR), and waist-to-height ratio (WHR) were used. Anthropometric data's correlations with radiological parameters of lumbosacrum were investigated. Results Anthropometric data of NC, WC, and BMI had no significant correlation with radiological parameters of lumbosacrum. NWR had significant positive correlation with lumbar lordotic angle and Ferguson's angle. NHR and WHR had no significant correlation with radiological parameters of lumbosacrum. Conclusions The results suggest that NWR-related fat distribution in neck has significant correlation with radiological parameters of lumbosacrum regardless of obesity.

  • Objective: This study investigated the relationship of anthropometric and metabolic risk factors with seminal and sex steroidal hormone parameters in a screened population of healthy males. Methods: The participants were healthy young men without chronic or congenital diseases. The body composition parameters that we investigated were measured weight, height, and waist circumference (WC), as well as bioelectrical impedance analysis. Semen samples were analyzed for semen volume, sperm concentration, sperm motility and morphology, seminal pH, and liquefaction time. Biochemistry analysis, including glucose and lipid metabolism parameters, was conducted on fasting blood samples. Testicular volume was calculated separately for each testis using ultrasonography. Results: Body mass index exhibited an inverse association with total sperm count. WC showed negative correlations with numerous seminal parameters, including sperm concentration, total sperm count, sperm morphology, and follicle-stimulating hormone levels. The basal metabolic rate was associated with seminal pH, liquefaction time, and sperm motility. WC, fat mass percentage, and triglyceride levels exhibited negative correlations with sex hormone binding globulin. The measures of glucose metabolism were associated with a greater number of seminal parameters than the measures of cholesterol metabolism. C-reactive protein levels were inversely associated with sperm concentration and total sperm count. Conclusion: Anthropometric and metabolic risk factors were found to predict semen quality and alterations in sex steroidal hormone levels.

  • The anthropometric characteristics of the intended user population are most important parameters in the equipment and workplace layout design, particularly in the airplane cockpit design. Because human body is composed of multi-dimensional body segments, single 'average' or 'extreme' manikin is not sufficient in computer-aided design(CAD) environments. To overcome this limitation, we constructed a manikin group representing Korean Male pilot population. First, we identified 16 anthropometric variables which are important parameters in the evaluation of reach, visibility, and clearance. And we found their correlations and conducted a factor analysis. Four common factors were extracted in the factor analysis. The first one was related with length dimensions, the second was with the arm reach, the third was with the sitting height, and the last was with breadth-depth dimensions. Finally, 17 manikins were constructed and presented in the CAD prototype.

  • This study analyzed the differences in aerobic and anaerobic exercise ability and growth-related indicators, depending on the polymorphism of the ACE and the ACTN3 genes, to understand the genetic influence of exercise ability in the growth process of children. The subjects of the study consisted of elementary school students (n=856, age $10.32{\pm}0.07yr$). The anthropometric parameters, physical fitness and growth factors were compared among groups of the ACE I/D or the ACTN3 R577X polymorphisms. There were no significant differences between the anthropometric parameters, physical fitness and growth factors for the ACE gene ID or the ACTN3 gene R577X polymorphism. However, the DD type of ACE gene was highest in the side step test (p<0.05), and the DD type was significantly higher than the II+ID type (p<0.05) in the early bone age. The combined group of the ACE gene II+ID and the ACTN3 gene XX type significantly showed lower early bone age (p< 0.05). This study did not find any individual or compounding effects of the polymorphism in the ACE I/D or the ACTN3 R577X polymorphisms on the anthropometric parameters, physical fitness and growth factors of Korean children. However, the exercise experience and the DD type of the ACE gene may affect the early maturity of the bones.
