The purpose of this study was to investigate the change of physical fitness, MDA, SOD after short-term weight reduction through exercise, food restriction and exhalation of sweat among Taekwondo players. The subjects ten male collage Taekwondo players with excellent practical skills, and more than seven years of experiences. They were asked to reduce about 5% of their body weight in seven days. Physical fitness levels were analyzed through grip strength, muscle endurance, flexibility, power, agility, balance, reaction time and MDA and SOD through blood test. The results of this study were as follows; First, there was no significant change in physical fitness due to short-term weight reduction in muscle strength, muscle endurance, flexibility, power, agility, balance and reaction time. Second, The change of MDA and SOD, resulting from short-term weight reduction did not show significant difference statistically. Therefore, the results of this study indicate that the Taekwondo players' short-term weight reduction of 5% of their body weight did not influence on their athletic performance and physiological capacity. Therefore athletes and coaches should endeavor to take exercise, dietary, and dehydration into consideration when conducting 5% of their body weight reduction in a week.

Among current health-related problems, the issue of over-weight is considered one of the most important, fostering a national interest in body weight loss. In this study, an awareness of one's current body weight and previous experiences of body weight loss were analyzed according to age and gender. The subjects of the study were 720 people (male: 360 and female: 360) aged $10{\sim}60$ years with previous experiences of attempting to lose weight 1 year prior to this study. Anthropometrics, general characteristics, awareness of one’s current body weight, and the body weight loss practice were analyzed through a questionnaire. Approximately 73.2% of the subjects recognized themselves as obese, and 83.5% wished to lose weight. The older the subjects were, the frequency of attempting to lose weight was lower, and those who succeeded in losing weight maintained their reduced body weight for a longer period. Compared to male subjects, more female reported attempts of losing weight, but the period of maintaining their reduced weight was shorter. The older subjects reported a higher satisfaction rate of the weight loss methods they used, and few of them gained back the weight they lost. This phenomenon was especially more stronger among male than female subjects. From our studies, it may be concluded that attitudes concerning a person’s current body weight and body weight loss practice vary according to age and gender.

Among current health-related issues, obesity is considered one of the foremost, and the importance of this subject has fostered a national interest in body weight loss. In this study, the differences in recognition of body weight loss according to age and gender are investigated. The subjects of the study were 720 (male: 360 and female: 360) aged between 10-60 years, who had experienced to try body weight loss during 6 months prior to this study. Anthropometrics, general characteristics, personal reasons for body weight loss, comprehension of body weight loss, and a knowledge of diet-related issues were assessed through a questionnaire. The anthropometric measurements showed significant differences in height, body weight (present and desired) and BMI (p < 0.05) by age and gender. The difference between desired body weight and actual body weight was greater for younger subjects or female, regardless of whether they had under- or normal body weight (p < 0.05). Reasons for body weight loss varied; younger subjects and female tended to lose body weight "to enhance their appearances", whereas the older subjects and male desired "to improve their health" (p < 0.05). Subjects had different concepts concerning body weight loss; younger subjects and female considered body weight loss as "maintenance of a slender figure, or becoming more lean". On the other hand, older subjects and male thought body weight loss to be "effects approaching normal body weight" (p < 0.05). From our studies, it can be concluded that attitude on concerning body weight loss varied according to a age and gender. Thus, consideration of this individual differences would be vital in developing contents of a particular nutritional education program for body weight loss.

The purpose of this study is to investigate isokinetic strength changes of knee joint in accordance with short-term weight loss of wrestlers. For this purpose, 14 male wrestlers of a K technical high school in B city participated in our research. The wrestlers were divided into two groups; one group of the wrestlers didn't lose any weight, and the other lost over 5% of their weights. The isokinetic strength was also observed before and after weight loss. The isokinetic strenght test were processed at test speed of the$60^{\circ}C$/sec, $90^{\circ}C$/sec, and $250^{\circ}C$/sec with the CYBEX NORM system(Cybex 770＋TMS, USA). Peak torque, peak torque %BW, total work, total work %BW, and endurance ratio were measured. Results showed that the isokinetic strength after the short-term weight loss of wrestlers decreased meaningfully Although endurance ratio didn't show any meaningful difference in our research, but more accurate research may find out the relationship between short-term weight loss and the endurance ratio of isokinetic strength.

최근 소득수준의 향상 및 식생활 습관의 서구화로 비만 유병율이 증가하면서 체중조절에 대한 관심이 급증하였다. 그러나 신체적 매력 중에서 날씬함을 너무 강조하는 사회적 분위기 등의 영향으로 자신의 체형을 왜곡되게 인식함으로써 이에 따른 신체에 대한 불만족은 무분별한 체중조절을 시도하도록 자극하는 요인이 되고 있으며 이러한 무리한 체중조절은 신체적·심리적 장애를 초래하는 것으로 알려지고 있다. 그러나 체형인식 및 체중조절에 대한 연구는 주로 젊은 여성들을 대상으로 한 것이 대부분으로 중년여성을 대상으로 한 연구는 거의 없는 실정이다. 따라서 본 연구에서는 자기체형에 대한 관심이 점차 높아지고 있는 중년여성들을 대상으로 비만도에 따른 체형인식 경향을 파악하고 체중조절에 영향을 미치는 요인들을 알아보고자 하였다. 조사대상은 도시지역에 거주하는 40세 이상 중년여성 249명으로 일반사항, 체형인식 및 체중조절태도, 이상식행동 등에 대하여 설문조사를 실시하였다. 모든 자료는 SAS program을 이용하여 분석하였다. 조사대상자의 평균 연령은 48.5세였으며 평균 비만도(BMI)는 22.7로서 정상범위에 속하였다. 비만도에 따른 체중군별 분포는 정상체중군이 72.9%로 가장 많았으며, 저체중군이 6.7%, 과체중군이 20.4%이었다. 자기 체형에 대한 인식도를 체중군별로 비교해본 결과, 정상체중군의 40.1%만이 자신의 체형을 ‘표준체형’으로 올바르게 인식하고 있을 뿐, 8.1%는 ‘마른 체형’으로, 51.7%는 ‘살찐 체형’으로 잘못 인식하고 있는 것으로 나타났다. 특히, 저체중군의 37.5%는 자신의 체형이 ‘표준체형’이라고 인식하고 있었다. 이상적으로 생각하는 체형에 대하여 조사대상자의 80.9%가 ‘표준체형’이라고 응답하였으며, 8.7%는 ‘마른 체형’을, 10.4%는 ‘살찐 체형’을 선호하는 것으로 나타났다. 자기 체형에 대해 조사대상자의 55.8%가 ‘불만족하다’ 고 응답한 반면 ‘만족하다’ 고 응답한 경우는 11.1%에 불과하였다. 그러나 체중조절에 대한 관심도는 체중군별로 비교해 보았을 때, 과체중군이 저체중이나 정상체중군에 비해 유의하게 높았다. 지난 1년 동안의 체중 감량 경험 여부를 조사해본 결과, 과체중군의 77.1%, 정상체중군의 65.3%, 저체중군의 62.5%가 체중감량 경험이 있는 것으로 나타났다. 체중감량 이유를 묻는 문항에 과체중군과 정상체중군의 경우 ‘건강을 위해서’라고 응답한 경우가 가장 많은 반면 저체중군의 경우 ‘체중이 증가되었기 때문에’라고 응답한 경우가 가장 많아 체중군별로 유의적인 차이를 나타냈다. 조사대상자의 53.8%가 체중감량을 하는 중 부작용을 경험한 적이 있는 것으로 나타났으며, 유의적인 차이는 없었으나 저체중군이 과체중이나 정상체중군에 비해 체중감량에 따른 부작용 경험자의 비율이 높았다. 이상식행동을 측정한 결과, 과체중이나 저체중군이 정상체중군에 비해 이상식행동 점수가 유의적으로 높았다. 세부요인별로 비교해 보았을 때, 체중조절에 대한 집착과 식이조절점수는 과체중군이 가장 높았으나, 섭식통제 관련 식행동 점수는 저체중군이 가장 높았다. 이상의 결과를 종합해 볼 때, 중년여성들의 경우 대부분이 자신의 실제 체형에 대하여 그릇된 인식을 갖고 있었으며, 체중을 감량하기 위해 지속적으로 노력하는 것으로 나타났다. 특히 저체중군의 경우 건강보다는 외모 때문에 무리한 체중감량을 시도하고 있었으며 이상식습관과 관련된 식행동 점수가 높은 경향을 보여 영양 및 건강 상태에 문제가 발생될 수 있을 것으로 생각된다. 따라서 중년여성들에게 자신의 체형과 이상체형에 대한 올바른 인식을 갖고 표준 체중을 유지할 수 있도록 지속적인 영양교육이 이루어져야 할 것으로 생각된다.

The purpose of this study was to conduct a questionnaire survey for total 503 high school female students in Wonju area, Kangwon province, and thereby determine any potential effectiveness of their trials to reduce weight in their satisfaction with their own figure, daily living practices related to weight control, nutrition knowledge and dietary behaviors. Out of all respondents, it was found that 284 girl students(58.4%) ever tried to reduce weight, and both trial group(trying to reduce weight) and no-trial group were much interested in weight control(94.7% vs. 60.7%). But 85.2% of trial group and 50.3% of no-trial group were dissatisfied at their figure. It was found that the percentage of trial group practicing regular exercise was higher than that of no-trial group doing so(21.8% vs. 5.5%). Subjects scored 14.3 out of 20 on a nutrition knowledge scale, but trial group scored significantly higher points(14.5) than no-trial group(13.9)(p<0.01). In particular, it was notable that trial group showed higher rate of correct answer in certain items such as balanced diet and knowledge about weight control. It was found that our all respondents showed moderate dietary behaviors, which is demonstrated by their mean score of 31.3 in dietary behaviors(possible score: $15{\sim}45$). Notably, it was found that there were problems exposed in their dietary velocity, intake of various diets and intake frequency for each food group(dairy products, marine plants and vegetative oil and fat). And it was found that the percentage of trial group taking diet with vegetative oil was higher than that of no-trial group.

This study was attempted to evaluate the effectiveness of extract of fermented red pepper The extract of fermented red pepper was prepared from fermented red pepper puree and polydextrose. Sixteen female college students were participated in this 8 weeks weight control program. All subjects were randomly assigned to the Internet Diet (ID) group or Internet I, fermented red pepper (IR) group. Mean energy intake of ID group was 1,279.9$\pm$112.0 kcal (carbohydrate: 66.9%, protein: 17.4%, fat: 15.6%) and IR group consumed 1,223.8$\pm$57.1 kcal (carbohydrate: 66.3%, protein: 19.3%, fat: 14.4%) during program. The ID group lost 2.5$\pm$1.0 kg of body weight, 0,9$\pm$0,7 kg of fat mass and 1.6$\pm$0.7 kg of lean body mass, and the IR group lost 2.7$\pm$0.3 kg of body weight, 1.8$\pm$0.6 kg of fat mass and 0.9$\pm$0.7 kg of lean body mass. There was no significant differences in the loss of total body weight & lean body mass between two groups, however, the fat mass and the abdominal fat were significantly decreased in the IR group compared to the IC group (p<0.05) The ID group experienced a significantly reduced Resting Metabolic Rate (RMR), however, IC group slightly increased. The change of RMR between groups were significantly different (p<0.05) . There were no differences in the change of blood glucose, total-cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride between groups. Therefore, the intake of fermented red pepper doting the weight control program might decreased the body fat especially abdominal fat and prevent the decline of RMR during weight reduction period.
