Nutrient supplements are often used by athletes as ergogenic aids. This study was done to investigate the use of nutrient supplements, nutritional knowledge and nutrient intakes of athletes. Subjects of this survey consisted of 195 national team athletes. The prevalence of nutrient supplement use among all subjects was 30.3%, and the frequency of use, by decreasing order, was weight lifting, taekwondo and badminton athletes. Sport drinks were the type of nutrition supplement used most frequently and vitamin C was the second one. Major reasons for nutrient supplement use were to improve training performance and to recover from fatigue, to supplement fluid and to control weight. The average score of nutritional knowledge was $19.9\pm{2.5}$ for nutrient supplement users, and $19.8\pm{3.6}$ for nutrient supplement nonusers. Intakes of protein, calcium and niacin of the user were higher than those of the nonuser. This information provided by this study can help sport nutritionists identify nutrient supplement most often consumed by national elite athletes and can aid counselors as they guide athletes towards more healthful nutrition practices.

Objectives : The $2^{nd}$ to $4^{th}$ digit length ratio(2D : 4D) is a sexually dimorphic trait regardless of ethnicity and shows sex differences. According to previous research, men usually have a relatively shorter $2^{nd}$ digit than $4^{th}$ digit. There is tendency that men with lower 2D : 4D are perceived as being more masculine and tend to perform better in some physical sports. Furthermore, 2D : 4D is negatively associated with trait aggression. In this study, we examine gender difference of 2D : 4D and compare 2D:4D of female Korean national team members to 2D : 4D of control subjects. Besides that, we also compare 2D : 4D of female Korean national team members according to their sports entries. Methods : The sample of this study is 396 people, 67 female Korean national team member, 216 control women and 113 control men. We measured $2^{nd}$ to $4^{th}$ digit length of their right hand. In addition, we collected demographic information of female Korean national team members using a self-report questionnaire. Results : The mean 2D : 4D of female Korean national team members is 0.96(SD=0.04), smaller than control women's 2D : 4D(0.97, SD=0.03) and significantly higher than control men's 2D : 4D(0.95, SD=0.03). We also found differences between control men and women. Non-martial arts related sports athletes have significant difference with control men in 2D : 4D. However, martial arts related sports athletes' 2D : 4D is not significantly different from other groups, including control men. Conclusion : These results are consistent with the findings of previous research that there is a significant difference between men and women in their 2D : 4D. Furthermore, 2D : 4D of martial arts related sports athletes have not shown any difference from the 2D : 4D of control men that 2D : 4D of non-martial arts related athletes have shown. This fact is important in consideration of masculine characteristics. For further research, it is necessary to examine 2D : 4D difference according to sport ability and gender differences.

The purpose of this study was to analyze, in real time, the glide motion and release motion of domestic athletes and gold and bronze medalists employing the glide technique for the men's shot put at the Daegu World Athletic Championship in 2011. In the glide motion, the Korean athletes had a relatively high body center and shot put heights and lager stretching angles for their hips and knees. In the delivery phase, which shifts to the release phase, the Korean athletes showed slower vertical body center and shot put speeds, and they changed the phase, to the release phase by using a small body angle. In the release phase, the Korean athletes showed differences in their projection speeds and vertical body center speeds. The world-famous players showed high angle speeds, which refer to the composition of the rotation force at the moment of release (body, hip, and shoulder line). In the release phase, the Korean athletes did not have fully stretched hip and knee angles, which might have negatively influenced the vertical speed. Because the Korean athletes showed relatively low projection heights and projection angles. it was found that they need to enhance the muscular power of their, throwing arms and lower limbs.

The purpose of the present study is to observe in-depth what kind of changes the establishment of a female basketball team in a college of education and the experiences the female basketball players have within that situation bring to their lives and their paths in life and social implications. To achieve this purpose, the female basketball team at the Department of Physical Education in P University was selected as a research environment and its members as research participants and qualitative research was conducted. Research results showed first, that female basketball athletes were already on a set path before they entered college. They had not thought about their path in life independently and had a passive attitude towards their life paths and were experiencing a culture in which studies were not permitted. Second, female basketball athletes discovered a new path upon college entrance. While meeting various friends, they gained friends and not just colleagues and after becoming aware that the main character in their lives is 'themselves', they showed autonomy. Based on this, factors for their change, which are the implications of this study, were first, the environment of P University's college of education which has strict regulations and a strong emphasis on academics when compared to other universities, second, the identity of being the first enrollments into the female basketball team of P University's college of education and the distinct characteristics of being a female athlete, third, the group's leader who contributed to their positively directed change. Ultimately, these factors served an important role in leading their change in the large frame of a university environment.

The purpose of this study is to understand the effect of violence in sports on intention to sport continuance among female athletes and to analysis the mediating effect of depression and the difference groups according to help-seeking. In order to accomplish these purposes, this study surveyed from September to October in 2010. The final subjects in the analysis were 345 female athletes who are belong to school athletic team, professional team, business team, and national team. The data were analyzed with SPSS 18.0 and AMOS 10.0 for conducting multiple group analysis. The main results of this study are as follows; First, those who were suffered by emotional violence were 62.4%; those who are damaged by physical violence were 28.6% among the participants in this study. In case of intention to sport continuance, when measured by a rule of five, was average 3.15. 29.9% of the female athletes scored above the standard of depression. Second, depression turned out to have a partial mediating effect within the relationship where violence in sports has effect on intention to sport continuance. Third, between experimental and non-experimental group on help-seeking among female athletes, there was a statistically significant difference in the structural relationship. This means that help-seeking has moderating effect within the path of violence in sports affecting depression. Based on the results, this study suggested that there is a strong need for intervention for the both prevention and cure of the sports violence. It is necessary to develop preventive programs and coping strategies on female athletes' depression and intention to sport continuance.

This study is to present more effective starting skills through analysis of kinematic characteristics of starting motions in 300m Time Trials of Inline Skating. To achieve this goal, 6 athletes, 3 in the national team and 3 in business teams were chosen and their starting motions were examined with three-dimensional image analyses. The results of analyses in regard of positions and speed of the bodily center and angles, angular velocity, and linear velocity of articulations of lower limbs by sections of starting motions are as follows: In case of the central position, though it is effective to reduce the air resistance by lowering the upper part of the body maximumly, it is reasonable to accelerate by raising the upper part of the body to some degree for the running posture at the lower speed in the starting section. In the starting section, it is efficient to minimize the period of time in touching the ground. for this, it is necessary to train for taking motions without slippage while touching the ground. While 3 athletes in business teams kicked the ground as running right after the starting, the others in the national team slid on the ground. As the number of steps increased, the movable speed changed quickly. Thus the movable speed of athletes in the national team indicated big differences in two to three steps. If these factors are well supported, the push-away starting method might be better than the running starting method in terms of improvement of records.

PURPOSE: This study examined sports injuries among national sitting volleyball players and to provide baseline data for the development of programs to prevent injuries and enhance performance. METHODS: The study surveyed 21 national team athletes (12 males and nine females) participating in the 4^th Hangzhou Asian Para Games. The questionnaire consisted of 17 items, including general information, type of disability, sites and types of sports injuries and their causes, the current state of sports injuries and the treatment and management of injuries. RESULTS: The survey results suggested that the most common injury sites were the finger, shoulder, and waist. The most frequent types of injuries were sprain, muscle cramp, and LBP. The causes were insufficient warm-up, playing unhealed and carelessness. Injuries were most prevalent during morning training and in the winter. Most injuries occurred in practice, and the actions most likely to cause injuries were blocking, spike and sitting movements. Ice and spray were the most common treatments, usually administered by the athletes themselves. Physical therapy was the most common post-injury management, and the most common sequelae involved continuing to use despite pain. CONCLUSION: Based on these results, systematic and individualized training and therapeutic support tailored to the characteristics of sitting volleyball and the types of disabilities are necessary to prevent and manage sports injuries among national players. Continuous injury management by medical staff, particularly physical therapists, is essential to maintain the health of disabled athletes.

PURPOSE. A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS. Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, ${\chi}^2$ test was used and significant level (${\alpha}$) was set up as 0.05. RESULTS. Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION. Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.
