The Purpose of this study was to examine the kinematic analysis of the upper-limb motion of wheelchair basketball free throw shooting. Three-dimensional kinematic data were obtained from 8 male wheelchair basketball players performing a successful free throw. Players were divided into three groups, according to their IWBF classification(Group 1: 1 point players, Group 2: 2-2.5point players and Group 3:3.5-4 point players) Wheelchair basketball free throw motions were taken by video camera. The three-dimensional coordinates was processed by DLT. Players from Group 1 and 2 tended to release the ball from a lower height, with greater velocity and release angle. Players from Group 1 showed greater shoulder horizontal adduction and horizontal abduction angle, wrist ulnar flexion and radial flexion angle, and trunk angle. but players from Group 2 appeared lower shoulder abduction. Upper limb angular velocity showed most greatly in hands from Group 1, upperarm from Group 2, and forearm from Group 3.

This study aims to provide the basic biomechanical data on the average, maximum and distribution of plantar pressure during hockey penalty stroke by comparing five skilled and five unskilled players. Following are the conclusions. First in the case of average and maximum planter pressure during penalty stroke, the skilled players showed higher pressures at the moment of left foot landing in rear plantar of left foot and fore, rear plantar of right foot compared to the unskilled players. Also at the moment of impact, the skilled players showed higher pressures in fore, rear plantar of left foot and fore plantar of right foot compared to the unskilled. The analysis drew the conclusion that the skilled players move their center of body from fore, rear plantar of right foot to fore, rear plantar of left foot at the moment of left foot landing and impact in order to perform a quick and strong shooting. Second in the case of plantar distribution, as the skilled players put over 70% of their weights on left foot, they showed overall higher plantar pressure distributed on the outer fore, mid and rear parts of left foot plantar, in contrast with the unskilled players who showed about 50/50 distribution of weights on their right and left foot. The analysis concluded that such distribution was shown because the skilled players transferred their weights from the right to left foot effectively while the unskilled players could not do so.

The objective of this study is to provide basic information on coupled motions in thoracic spine during lateral bending from a neutral position for football and baseball players as well as for general university students. In the experiment, a total of 30 subjects participated(football players: 10, baseball players: 10, general students: 10). All subjects were in their 20's. The subjects sat on a chair with lumbar support in a neutral position and bent to the right. As a result, for baseball players, coupled motions were observed in the opposite direction of the lateral bending in all parts of thoracic spine. For both football players and general students, coupled motions were observed in the same direction. These results confirmed that unilateral movements like baseball could affect coupled motions.

Ssireum, the traditional Korean sport, is very popular at both amateur and professional levels. Ssireum players are prone to be obese which related to the chronic disease in their later life. The purpose of the study was to compare the anthropometric measurements, quality of diet, and blood parameters of Ssireum players with those of subjects who were matched body mass index, gender and age. Participants in the 3 groups, Ssireum players (SP, n=15), regular moderate exerciser (RME, n=15, >3 times /wk, >20 min/time) and intermittent light exerciser (ILE, n=14) groups. Anthropometric measurements included height, weight, fat mass (by Dual energy X-ray absorptiometry), lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), dietary variety score (DVS). Blood levels of lipids, leptin and insulin were analyzed. As a results lean body mass and mid-arm circumference were significantly higher in Ssireum players than those of other groups (p<0.01). Total body fat, trunk fat, abdominal skin fold thickness and waist-hip ratio were significantly lower in SP group than those of other groups (p<0.01). DVS were higher however, dietary quality was low in Ssireum players than in other groups. There were no differences among the 3 groups in regard to blood total cholesterol, LDL-cholesterol and glucose levels however, leptin level was low in Ssireum players. These results indicate that Ssireum players had significantly higher lean body mess and lower body fat when these were compared with regular moderate exerciser and intermittent light exerciser. Blood leptin levels of Ssireum players were low but blood lipid profiles were not significantly different.

The purpose of this study is to investigate whether there are differences in physique characteristics between the excellent domestic player groups in each sport player's, to prevent epidemiologic damage of musculoskeletal system and to provide fundamental data to improve performances for players. This study has performed for total 60 student players from Y University in Yongin, Gyeonggi-do, consists of 20 Kendo players, 20 Judo players and 20 Taekwondo players. We measured the length and circumference of arm, leg, body using Martin anthropometer to collect the data for 3 groups. There was significant difference in lower left arm length between player groups(p<.01), and Kendo players' right side femoral were longer than other 2 groups for leg length measurement(p<.01). Judo players' circumference for right/left stretched arm/bent upper arm were thicker than other 2 groups(p<.01). Taekwondo players' chest circumference were smaller than other 2 groups(p<.01), and Taekwondo players' right/left femoral circumference were thinner than other 2 groups(p<.05). From this study, it was found that there are physique characteristics differences between the Kendo, Judo and Taekwondo player groups. This indicates that repeated exercise for each sport player causes physique change, and it may cause epidemiologic damage of musculoskeletal system. It is recommended to perform balancing exercise prior to main exercise.

게임을 플레이하는 사람들의 범주가 더 넓고 다양해졌고, 새로운 속성들이 게임에 반영되고 있다. 이러한 변화에 따라 지금의 플레이어들이 게임을 어떻게 인식하고 분류하는지 이해하고 파악하는 것이 필요하다. 본 연구에서는 게임 플레이어 30명을 P표본으로 선정하여 디지털 게임 분류 요소에 대한 Q표본 29개를 기반으로 Q방법론을 수행하였다. QUANL 프로그램으로 분석한 결과, 총 3개의 유형이 구분되었다. 첫 번째 유형은 외부적인 관점에서 보이는 게임 구성요소를 중요한 분류 기준으로 인식하고 있어 '물리적 환경중심 플레이어'로 명명하였다. 두 번째 유형은 게임 내부에 존재하는 구성요소들이 게임을 분류하는 중요한 기준이라고 인식하기에 '콘텐츠 중심 플레이어'로 명명하였다. 세 번째 유형은 게임을 분류하는 데에 있어 게임 플레이어 자신의 주관적 느낌과 생각을 중요하게 인식하고 있어 '감성 경험 중심 플레이어'로 명명하였다. 본 연구는 지금의 게임 플레이어들이 실제 게임을 어떻게 인식하고 분류하는지, 그 유형과 특성을 프레임워크로 분류했다는 점에서 의의가 있다.

This study was done to investigate the 12 college volleyball player's food behavior, nutrient intakes, and their serum lipid levels during the periods of training and detraining and to provide basic data for an effective program for the volleyball players during the period of detraining after the game season. The results were summarized as follows : The total daily energy intake of the players was $3,363{\pm}339kcal and 3,692{\pm}499kcal$ during the periods of the training and detraining, respectively. During the training period, daily intakes of protein, calcium and vitamin A, and $B_2$ were lower than the recommended dietary allowance for the players. During the detraining period, the players' daily intakes of calcium, iron, and vitamin A were even lower. However, the consumption of alcohol was dramatically increased during the period of detraining. The levels of serum triglyceride and very low density lipoprotein were significantly increased during the detraining period. Basal metabolic rates were significantly increased after the training period and diastolic pressure was decreased during the detraining period. In conclusion, out results suggest that the detraining of volleyball players for 10 days after intensive training, negatively affects their food behavior and serum lipid concentrations. Therefore, for the improvement of performance for the next game season, a planned program for the players' detraining period should be developed.

Background: The objective of this research is to provide base line data on Korea Baseball rehabilitation treatment by presenting the distribution of upper extremity surgeries according the surgical sites of Korean professional baseball players. Methods: The targets of this research are 561 players from nine Korean baseball clubs. The number of players that have undergone surgery was investigated. In other words, the frequency of shoulder joint surgeries, elbow joint surgeries, and wrist and hand surgeries per each baseball club was investigated. Results: The number of the players who have had surgeries was 151, but among the players, there were some who have had repeated surgeries for which the total number of surgery experience was 162. The result showed that elbow joint surgeries were the most frequently enacted, followed by shoulder joint surgeries, and wrist and hand surgeries. From the nine clubs, Samsung was the club with the highest frequency of surgeries. Conclusions: This research shows that Korean professional baseball players need special training centers with systematic rehabilitation programs. Another conclusion suggests that urgent need for rehabilitation program of upper arm which particularly focused on elbow joint is existing. On the basis of this research, we expect more studies on the specific rehabilitation programs which is categorized by injury areas.
