This study was conducted to investigate weight control status and associated factors among health-related major female college students. The subjects consisted of 41 nutrition and 78 physical exercise major female college students. Nutrient intakes, biochemical index, nutrition knowledge (recognition and accuracy), interest of weight control, body satisfaction, self-recognition of health condition, self-evaluated body weight were studied. About 73% of nutrition and 79% of physical exercise major female students were in the normal range of BMI ($18.5{\sim}23$) and 2% of nutrition and 1% of physical exercise major female students were underweight, 10% of nutrition and 6% of physical exercise major female students were obese. There were no significant differences in height and weight by major but %body fat and WHR in physical exercise majors were significantly lower than nutrition major students (respectively p<0.01, p<0.05). Overall, nutrition intakes of subjects were not shown to be appropriate, especially Ca/P of subjects was shown $0.54{\sim}0.64$, fat% out of energy of subjects was shown $24.7{\sim}29.0$ and Na intake was shown above 2000mg. Recognition and accuracy of nutrition were higher than those of physical exercise majors (p<0.001). There were no significant differences in self-recognition of health condition, self-evaluated body weight, satisfaction of body shape by major and weight control attempt. But interest of weight control of attempter was higher than that of no-attempter in nutrition (p<0.05) and physical exercise major students (p<0.01). Significantly negative correlation was found in satisfaction of body and BMI, body fat mass, %bodyfat, WHR. And significantly positive correlation was found in interest of weight control and BMI, %bodyfat, WHR. It was noticeable to see that interest of weight control was positively correlated to accuracy and accuracy was negatively correlated to blood cholesterol level. Therefore, proper nutrition education for female college students is needed in order to improve their weight control-related health.

본 연구에서는 근적외선대역의 광원을 이용하여 생체측정 시 에러로 작용하는 피하지방층의 두께를 추정하는 방법의 가능성에 대해 검토한다. 현재까지 피하지방층의 두께측정을 위해서는 초음파장비나 CT, Dexa 장비 등 고가의 장비로 측정을 하는방법 이외는 특별한 수단이 없는 것이 현실이다. 정확한 측정을 위해 피하지방층의 두께를 제거하는 것이 일반적인 연구의 목적이나 본 연구에서는 이들 피하지방 두께 측정을 최근 주목받고 있는 건강에 적용하고자 한다. 본 연구의 피하지방층의 두께추정방법의 가능성이 보여진다면 체지방측정에 있어 몸 전체의 체지방을 추측하는 방식인 BIA방식의 체지방측정방법과 비교하여 특정부위에 대한 피하지방층 측정도 가능할 것이라는 기대도 할 수 있다.

The purpose of this study was to investigate the effect of mechanical massage on abdominal region on the reduction of abdominal fat in obese middle aged women. 10 middle aged obese women were participated in as subjects and executed 20~30min's mechanical abdominal massage for 4 weeks. At the beginning and end of 4 week's treatment, measured body composition, waist circumference and abdominal fat area and analyzed using SPSS. As a result, there were significant decrease in body weight(p= .003), % bodyfat(p= .018), waist circumference(p= .029), VFA(p= .007), SFA(p= .045) and TFA(p= .007) according to 4 weeks' treatment. Considering these results, it can be suggested that mechanical massage treatment on abdominal region in middle aged obese women be a effective method to reduce abdominal fat and furthermore to prevent and cure cardiovascular disease and metabolic syndrome caused by obesity.

The purpose of this study was to evaluate the effect of a nutrition education program on 42 obese young adolescent girls. Nutrition education was performed for six months including both group and individual programs, and was focused on improving their eating habits and food composition. The topics discussed once a week included : eating habits, lifestyle management, 5 basic food groups, snack and fast-food, how to eliminate empty calories, fat and hyperlipidemia, food diary, benefits and methods of exercise, vitamin and minerals, evaluation of fad diets, yo-yo effects and so on. The effects of the nutrition education program were evaluated for nutrition education and exercise regimen group (NE＋E), nutrition education only group(NE), and control group(C). NE＋E group had additional exercise programs 3times each week, while NE group was educated about exercise only by a nutrition education program. In both NE＋E and NE groups, there was a significant decrease in bodyfat compared to C group, but NE＋E group had a greater change than NE group(5.5% vs 3.1%). In addition, serum triglycerides decreased about 40mg/dl and total cholesterol 20mg/dl in both NE＋E and NE groups. But HDL-C level was increased only in NE＋E group. The greater changes in body fat and blood lipid levels occurred between the pre- and mid terms fo the education regimen. They kept their changed measurement throughout the 6 months follow-up studies. The results of this study show that this nutrition education program is helpful for obese adolescent girls in decreasing body fat and serum lipid levels. Also, the combination of an exercise regimen with the nutrition education proved to be more effective.

Pressurization walk training (PWT) with blood flow occlusion has been investigated with regard to muscle hypertrophy and physical fitness function in athletes and healthy people. However, the cardiorespiratory and cardiovascular responses of obese people to PWT are unknown. Thus, we investigated the effects of PWT on body composition (Weight, FM, LBM, %fat, BMI), cardiovascular responses (HR, SV, CO, TVC), and cardiorespiratory responses ($VO_2max$, VEmax, HRmax) in middle-aged obese women. They participated in walk training with (n=15) blood flow occlusion and cross-sectional areas of the quadriceps on both legs. Five sets of 3-min walking (5.5 km/h at 5% grade) and 1-min resting were performed twice a day, 5 days/week for 3 weeks. The results showed that the LBM was significantly increased, and decreased body weight of reducing FM, %bodyfat in PWT ($p$<0.05). For the cardiovascular response, SBP and TPR were significantly decreased ($p$<0.05), and CO increased ($p$<0.05). In addition, the $VO_2max$ and VEmax were improved through PWT. Therefore, this study suggests that the presence of obesity in middle-aged women may result in body composition, cardiorespiratory, and cardiovascular responses caused by PWT.
