This study investigates the actual domestic and overseas cyclewear wearing conditions for male high school cyclists. The study results provide factors and degree of dissatisfaction as basic data for cyclewear development. This study was conducted on 35 male high school cyclists (freshman to seniors) by a questionnaire and interview method. Study results were: Male high school cyclists considered functionality as most important when they bought cyclewear and the brand they most often bought was a cheap domestic brand. Dissatisfaction with the crotch, thigh circumference and minimum leg circumference was higher than other parts during wearing. A cyclist is more sensitive to wear because they require more lower body motion than other parts. Cyclewear should be: less transformed even by frequent laundering, made of breathable material and use a sewing technique that minimizes air resistance and increases fit the body. Functional pads ergonomically designed with high tactile materials should be developed to prevent 'saddle sore' and groin soreness region that happens because of a lower body bending posture when cycling. A follow-up study is recommended to further develop excellence in cyclewear functionality and dimension suitability for male high school cyclists through the size system.

This study examines the characteristics of fat body type males aged 35 to 55 with a BMI rate higher than 25 categorized as mid-degree obesity and high-degree obesity according to the $6^{th}$ Size Korea; in addition, the study provides a sizing system for obese males. The physical characteristics of the obese male appeared to be with a shorter lower body compared to an upper body for a higher degree of obesity. Obesity appeared evenly from chest to thigh circumference compared to a normal group. Especially, their waist measurement, depth, and width were significantly larger as well as the crotch length (natural indentation) and a larger waist measurement. As for the cloth sizing system, this study suggests the sizes with higher distribution among the designated size intervals of casual tops, men's suit tops and bottoms based on standard stature, chest size and waist circumference (Omphalion) by KS.

The purpose of this study was to investigate the differences in anthropometric, hematologic, and lipidologic data between normocholesterolemia and hypercholesterolemia and influencing factors in hypercholesterolemia in middle-aged men in Kwang-ju. 179 middle-aged men were involved. Anthropometric data(body weight, height, body circumferences and skinfold thickness) and hematologic data(blood pressure, fasting blood glucose, albumin and hemoglobin) were measured. Bleed lipid profile(total cholesterol, tr- iglyceride, phospholipid, HDI-cholesterol, LDL-cholesterol and VLDL-cholesterol) were analyzed. To determined using questionnaire. The subjects were classified as hypercholesterolemic based on The Guideline for Korean Hyperlipidemia. body mass index, systolic blood pressure, waist and hip circumference, and triceps, subcostal, abdomen, subscapular and suprailliac skinfold thicknesses of the hypercholesterolemic group were significantly higher than in the normocholesterolemic group. The concentrat- ion of cholesterol, triglyceride, phospholipod. HDL-cholesterol, LDL-cholesterol and VLDL -cholesterol of the hypercholesterolemic group were significantly higher than normocholesterolemic group. The concentration of cholesterol has a significantly positive correlation with body mass index, diastolic blood pressure, waist circumference, waist/thigh ratio and skinfold thickness(triceps, subcostal, abdomen, and supraillic skin- fold thickness). The general tendency of socioeconomec status, frequencyu of meat intake, smoking amounts and duration and duration and drinking frequencies and amount were higher in the hypercholesteolemic group but not significant. In conclusion, hypercholesterolemia in middle-aged men was closely correlated with upper body fat obesity and most of them had an accompanied high triglyceride level tendency.

The purpose of this study was to present a good pants pattern for boys aged 13-18 by comparing and analyzing the pants pattern according to lower body shape. And through it, this study was to provide basic data for pants production considering male student body shape. The pattern of this study used the industrial type Lee Hee-chun pattern and DC Suite Program for 3D virtual simulation. As a result of the appearance evaluation, there was a significant difference between the patterns in most items. Type 2 was rated highly, followed by Type 4, Type 3, and Type 1. Type 1 required correction of the length of the pants and the amount of crotch part, while type 3 required adjustment of the pants in the knee area. Type 4 required correction of pattern drawing method of crotch width, thigh circumference, and knee circumference. This pattern method was evaluated as suitable for slender body shape. This study suggests a pants pattern system suitable for adolescent boys by reflecting the body shape characteristics of adolescent boy with a change of body shape. It is expected that this will meet the increasing demand for fitting. In this study, we have examined 3D virtual simulation, not actual wear experiment, so it will be necessary to investigate the difference through actual clothing experiment for adolescent boys.

The purpose of this study was to investigate the pre- and post-exercise performance, edema, and pain of plyometrics in water and land environments. Twelve males in their 20s were selected as subjects and performed 10 sets of squat jumps 10 times in 2 environmental conditions (water and ground). There was no significant difference in iEMG of vastus medilais according to exercise conditions and time. In MPV of CMJ, there was no significant difference according to exercise conditions and time. The thigh circumference showed a significant difference according to the exercise condition and time, and was higher in the ground condition after exercise. There was a significant difference in pain according to the exercise condition and time, and it was found to be high after exercise, 48 hours, and 72 hours in the ground condition. We believe that plyometric training in an aquatic environment will have less swelling and pain compared to plyometric training conducted in a land environment, and the pain will improve quickly, so we think that training can be conducted in a relatively shorter period than in the land environment.

Objectives : This study was performed to identify the efficacy and safety of ephedra and green tea mesotherapy on localized fat. Methods : Twenty-five healthy $20{\sim}35$ year overweight women (body mass $index{\geq}23kg/m^2$) were recruited and randomly assigned to two groups : experimental(mahuang and green tea) group (n=13), placebo(Normal saline) group (n=12). Total 8 times of herbarl mesotherapy treatment were performed once per week, 4 times were performed on right thigh (1st period), after wash-out for 1 week, the other 4 times were performed on left thigh (2nd period) without any modification of diet or exercise. Body composition, thigh circumferences were measured at each period before and after the intervention. Subcutaneous fat was measured by CT scan at before and after the 1st period of intervention and free fatty acid(FFA) was measured immediately before 1st intervention, 1 hour later, 24 hours later, and 7 days later. Satisfaction score and adverse events were evaluated. Results : In the subcutaneous fat, there were no significances, but in the circumferences. Experimental group had significant change when compared with placebo group (p<0.05). In FFA, experimental group has significant elevation at after 1 hour (p<0.05) evaluation. There were no serious adverse events in both groups. Conclusions : Experimental group had some significant findings in circumference, FFA, and had no serious adverse events comparing with placebo group, and no serious adverse events have been reported in both group. Mesotherapy with herb have a possibility of treating localized fat

This study collected the basic data required to develop a slim-fit jeans pattern for upper grade elementary school girls. First, a fit evaluation was made by selecting five slim-fit jeans of ready-to-wear brands. Subjects were four girls aged 11-12 with an average body size that evaluated the appearance and motion functionality of five brands of jeans. Five experts also evaluated their appearance. Second, pattern sizes were analyzed and compared with the average size of upper grade elementary school girls by measuring the pattern sizes of five brands jeans. As a result, Brand A received a high score in appearance and motion functionality. Brand E scored high with Brand A in appearance, while Brand E had the lowest score in motion functionality. For most of the five brand jeans, (+) ease was added to include a wide range of body sizes for upper grade elementary school girls, but the hip circumference, thigh circumference, and knee circumference of Brand E jeans were smaller than the average size of girls. The (-) ease was applied to make the figure look slim, which resulted in a high appearance score. However, since Brand E received a low score in the motion functionality, it could be seen that the (-) ease was not suitable for subjects although the material was stretchable. The result of this study will be used to develop a slim-fit jeans pattern suitable for upper grade elementary school girls.

The purpose of this study was to compare the energy expenditure of normal-weight and overweight Korean middle-aged women (40-60 yr). Middle-aged oveweight ($BMI\;{\geq}\;25$, n= 20) and normal-weight women were ($BMI\;{\leq}\;23$, n = 20) were recruited in Seoul. Anthropometric measurements, body composition, energy intake, daily activity time, and energy costs of some daily activities were measured. Energy expenditure at rest and while reading the newspaper, washing dishes, mopping the floor, and walking on a treadmill at 1.0, 2.0, 3.5mph were measured by indirect calorimeter and total daily energy expenditure was estimated by summation of energy costs of different activities. The overweight group had significantly higher values of body weight, triceps skinfold thickness, thigh circumference, waist circumference, hip circumference, BMI, WTR, WHR, body surface area, percentage body fat, fat mass, fat free mass (FFM), and muscle mass compared to normal-weight group. The energy intakes of both groups were close to RDA and other nutrient intake status was also satisfactory. There were no significant differences in intakes of energy and nutrients between the two groups. Overweight subjects showed lower energy expenditure per kg body weight for reading the newspaper, washing dishes and mopping the floor, and walking on a treadmill at 2.0 and 3.5 mph, however, energy expenditure per kg FFM did not differ between the two groups. Daily energy expenditure for all activities was significantly higher in the overweight compared to the normal-weight group due to higher body weight. Both overweight and normal-weight groups showed negative energy balance between energy intake and energy expenditure, and there was no significant difference in energy balance between the two roups. Total daily energy expenditure correlated highly with FFM and body surface area. The result of present study does not offer an explanation on the energy imbalance and weight gain of overweight women.

The purpose of this study was to analyze the physical characteristic of the wheelchair users by directly measuring the disabled men who use a wheelchair and to classify body types. The subjects were 178 male wheelchair users 20-69 years range of age. The results of this study were as follows. The cause of disability was classified into four groups; Poliomyelitis(P), Spinal Cord Injury(S), Cerebral Palsy(C), Amputee(A). There was a remarkable difference in the physical characteristic of the wheelchair users due to their cause of disability. A have greater values in all the dimensions. P have the largest drop values and smaller values in the lower body dimensions. S have greater values in the height of upper body trunk, back interscye length, and chest circumference, whereas smaller values in waist front length and thigh circumference. C have smaller values in most body dimensions except circumference of lower limb. By the factor analysis on the anthropometric data came out the result to be eight factors. The result of cluster analysis using factor scores shows the body types of wheelchair users can be divided into four body types; PY, RBB, TBP, RA. PY type is short and has the largest drop values, whereas RBB type tends to have the smallest drop values. TBP type is tall and the torso tends to be larger than those of the other types. RA type has smaller values in front body dimensions and moderate values in other dimensions. The diversity in body types should be considered among the wheelchair users.

The aim of this study is to provide fundamental data on the development of ready-to-wear clothing appropriate for the lower body types of male students who play sports in college. The study was conducted by means of targeting 151 male sports majors between $18{\sim}27$ years of age. Characteristics of the respondents were ascertained by means of questionnaires and an evaluation of a total of 36 lower body features. The results of the study are as follows. 1. A comparison of anthropometric measurements with the National Anthropometric Survey of Korea (1997) revealed that the main characteristics of the lower somatotypes of male sports college students are large circumferences and developed muscles of the lower body. 2. Sports were classified into the following five categories : soccer, bodybuilding, wrestling, judo, and taekwondo. In particular, bodybuilding students demonstrated a somatotype with an increased circumference, depth, and width of the thigh and lower body. 3. Somatotypes were classified into 3 types by means of a cluster analysis employing S factors. Type 1 somatotype exhibits a large circumference in the lower body. Type 2 is a lower somatotype of a middle size. Finally, Type 3 encompasses a smaller group in weight and circumference with a developed calf and ankle. 4. Each group was evaluated using a discriminatory analysis as a check to see if the groups had been discriminated with accuracy. The total accuracy rate was 96.0%.
