This study investigates coping strategies of overweight or underweight males in Korea. For this purpose, the authors identify types of stress related to weight management. A qualitative method was utilized to collect the data related to successful weight management experiences of males aged 20-37 years. Data were analyzed based on a motivation theory of coping, which suggests coping strategy elements. The results of this study identified the stress related to weight: dissatisfaction with appearance, others' disapproval of appearance, health problems, weaker athletic ability, negative self-perception, passiveness about appearance, lower romantic attractiveness, others' disapproval of lower romantic attractiveness, weakened task execution capability, and negative stereo-types about task execution capability. In addition, six coping strategies were suggested: improved appearance, improved physical function, improved positive self-perception, more choices to improve appearance, enhanced romantic relationship, and enhanced job performance. This study shows that weight problems in modern society are diverse and complex. Therefore a man who has abnormal weight needs to clarify his stress first and then proposes strategies that are appropriate for each type of stress.

심폐 지구력은 유전인자에 의해 부분적으로 결정되며, 현재까지 이루어진 연구 결과에 의하면 안지오텐신 전환효소 유전자에 존재하는 다형성과 이 형질 사이에 유의한 관련성이 보고되고 있다. 그러나, 이러한 연구는 주로 서양인을 대상으로 수행되었기 때문에 유전적 배경이 다른 아시아 집단에 대해서는 아직까지 이렇다 할 연구 성과가 없는 실정이다. 이에, 본 연구에서는 아시아 집단중에서도 민족적으로 순수한 한국인 집단을 대상으로 안지오텐신 전환효소 유전자에 존재하는 다향성이 한국인 집단에서도 심폐 지구력과 유의한 관련성이 있는 지를 조사하였다. 그러나, 한국인 운동선수군을 대상으로 한 연구에서는 안지오텐신 전환효소 유전자의 다향성이 심폐 지구력을 비롯한 신체 계측치 및 생화학적인 측정치 들과 어떠한 관련성도 나타내지 않았다(P＜0.05). 그러나, 본 연구 대상으로 다양한 종목에서 선발된 운동선수들을 표본으로 하였기 때문에, 단일 종목의 운동 선수군을 대상으로 한 추시가 요구된다.

This study was done to investigate the use of nutritional supplements (NS) in Korean elite soccer players using an anonymous questionnaire. NS were classified into health supplements, manufactured health food supplements, chinese medicines & tonic foods, and nutrient supplements. Information was sought on the type of NS and factors that might influence supplement use including selected demographic parameters and health related variables. The data were collected from 241 athletes (aged $24.6{\pm}3.8$ years) in 9 professional soccer club. The prevalence of NS use among the subjects was 81.3%. Health supplements were used most frequently and nutrient supplement drug was the second one. Among the health supplements, weight/muscle gainer and calorie replacement product were most frequently used. Vitamin supplements were most frequently used among all nutrient supplement drugs. Users of NS were higher age (p<0.05) duration of exercise (p<0.05), and income (p<0.05) than non-users. The married (p<0.05) and a member of K-league (p<0.01) tended to have higher prevalence of NS use. The main adviser of NS were family (55.3%) and oneself (39%) instead of coach or sports nutritionist. Although NS use, only 26.2% certainly check up nutritional information on their used NS. Among the subjects, 84.5% of them felt that NS use were improved athletic performance, and 86.5% of them will to keep on taking supplement. These data suggest that a large number of elite soccer players use NS and these players may require education about healthy nutritional supplement practice and on the proper use of nutritional supplements.

Dynamic visual acuity is used as an important factor to measure athletic performance in sports field. A study on visual acuity testing system using non-see head mounted display (NST-HMD) was conducted recently. However, the NST-HMD has a problem that the sense of space felt by the subject differs from the actual environment. This is because the view is blocked so that it is only implemented in a virtual space. This paper proposes a dynamic visual acuity testing system using optical see through head mounted display (OST-HMD). To do this, OST-HMD and NST-HMD comparative tests were conducted using existing K-D (King-Devick) charts. Experiments were performed on 30 subjects and their visual acuity was measured and analyzed by parametric statistics and one-sample T-test. The results of the study demonstrate the effectiveness of the proposed OST-HMD. This study is expected to use the visual inspection and training equipment of OST-HMD.

Background : Mahuang (Ephedra sinica) has been used widely to treat respiratory disease in traditional medicine for over thousands years. Mahuang preparations contain approximately $0.75{\sim}1%$ ephedrine alkaloids. Recently in North America, the Eephedra alkaloids has aroused a controversy due to its adverse effects in those using whole extracts as "dietary supplements" for weight loss or athletic performance enhancement. Objective : To discuss the need for clinical practice guidelines on the use of Mahuang. Results and Conclusion : It is widely assumed that Mahuang is one of the useful medicines and is safe for human body. Most of scientific literatures support that the safety of Mahuang prescription in common dosage. However, it has been claimed that there were some warnings and apprehensions about the harmfulness of Mahuang as dietary supplements. This article does not negate the fact that it is necessary to pay more attention for use of Mahuang in clinical situations. We assert that the establishment of clinical practice guideline on the use of Mahuang, which is based on scientific materials and consensus, is required in traditional medicine.

This study was conducted with 20 female gymnasts and 23 age-matched controls to examine pattern, weight control behavior and nutritional status. Most gymnasts(95.0%) reported that they used weight-control methods, while relatively few age-matched controls employed these methods. These methods included sauna(95.0%), food restriction(90.0%), excess exercise (70.0%), laxative abuse(10%) and use of diet pills(10%). Gymnasts had significantly (p<0.05) lower scores for statements related to 'sneaking food', 'vomiting after overeating', showing more negative eating behavior than age-matched controls. Energy intake of gymnasts was 968.9$\pm$421.4kcal while energy expenditure was 2,091$\pm$361kcal, showing negative evergy balance(-1,1225$\pm$534.6kcal). Female gymnasts consumed less than 70% of the RDA for protein, calcium, iron, vitamin A, thiamin, riboflavin and niacin, which reflects their low energy intake. The average intakes of calcium, iron, vitamin A, thiamin, riboflavin and niacin did not meet the recommended dietary allowances for their age groups. Adolescent athletes who train vigorously and consume a low-energy diet may be exposed to an increase in potential health risks. Therefore, individuals who advise athletic adolescents regarding training and dietary habits need to emphasize the importance of consuming an appropriate energy intake to support performance as well as growth and development. The sports nutritionist is in a position to convey such information to coaches, physicians, parents and to the athletes themselves.
