The aim of this study was to quantify the effect of kinesiotaping(KT) on subacromial space parameters in elite badminton players and compare them between athletes with subacromial impingement syndrome(SAIS) and asymptomatic controls. Eight badminton players with a clinical diagnosis of SAIS and 10 healthy players were examined using diagnostic ultrasound to measure the thickness of supraspinatus tendon(STT) and acromiohumeral distance(AHD) at 0°, 45°, and 60°of shoulder abduction. In 30 minutes after applying KT on lower trapezius and serratus anterior muscles and in 30 minutes after playing badminton, STT and AHD were reexamined, respectively. The ratio of STT to AHD was a lso calculated and compared. The pre - STT and post - STT in two groups were not different between groups. At 0° abduction, the SAIS group showed wider post - AHD and smaller post - STT/AHD ratio than preAHD, 30″ - AHD and pre - STT/ AHD, 30″STT/AHD, respectively. The control group showed wider post - AHD than 30″- AHD. At 45° abduction, the control group showed wider post - AHD than pre - AHD and 30″- AHD and showed smaller post - STT/AHD than 30″ - STT/AHD. It appears that KT on scapula has a temporary effects on increasing AHD and decreasing STT/AHD ratio regardless of impingement syndrome, especially with small shoulder abduction. It is not likely that functional improvement are related to applying KT in badminton players with SAIS.

This study investigated the relationship between A goal orientation and motivation type according to sex, school vs. industry, and the ability level. One hundred eighty Badminton players of high-schools, universities, and industries participated in this study. Findings are as follows: 1) Men players' internal motivation had a significant effect on external regulation. 2) Men and women players' ego orientation had a positive effect on internal motivation. 3) High school players' task orientation had a positive effect on internal motivation, whereas their task factor had a negative effect on non -motivation. 4) University student players' task factor had a positive effect on internal motivation. 5) Both high school and university student players' ego orientation had a positive effect on internal motivation. 6) Low level ability players' task factor had a negative effect on identified regulation and high level ability players' task factor had a negative effect on external regulation and positive effect on internal motivation. Finally, high level ability players' ego factor had a positive effect on identified regulation and internal motivation.

국가대표 배드민턴 선수의 타구 예측능력 향상을 위한 지각기술훈련 프로그램 개발과 적용

본 연구는 국가대표 배드민턴 단식 선수의 타구 예측능력 향상을 위한 지각기술훈련 프로그램을 개발하고 적용하여 그 효과를 알아보는것을 목적으로 하고 있다. 이를 위하여 경력 10년 이상의 국가대표 선수 8명(남자 4명, 여자 4명)이 실험에 참여하였다. 먼저, 지각기술훈련 프로그램 개발을 위해 선수들의 시선행동을 분석한 선행연구(구해모, 2005; 김선진 등, 2007)를 바탕으로 지각기술훈련 구성을 위한 필수변인을 선정하였다. 선정한 변인을 기반으로 선수 개인별 지각기술훈련 프로그램을 개발하였으며, 안구 움직임 추적 장치, 영상동조시스템, 시각차단 시스템을 활용하여 8주간 훈련을 실시하였다. 실험과제는 개발된 지각기술훈련 프로그램을 적용한 후 안구 움직임 추적 장치를 착용하고 실제 코트에서 서비스 후 상대선수가 무작위로 공격하는 타구(스매시, 드롭, 클리어)에 대해 수비하는 상황에서 시선행동, 반응 시간, 그리고 개인 면담을 통해 그 효과를 살펴보았다. 그 결과, 피험자들은 상대선수의 타구동작을 더 오랫동안 보고 타점으로 이동하는 시선행동 패턴을 보였으며, 상대선수의 타구 임팩트 후 더 빠르게 자신의 라켓과 무릎을 타구방향으로 이동시키는 것으로 나타났다. 시선고정 위치에서 공격 구간에서 셔틀과 몸통 영역의 시선고정시간이 감소하고, 팔 영역의 시선고정시간이 증가하였다. 지각기술훈련 효과에 대한 선수들과의 면담에서도 긍정적인 변화가 있는 것으로 나타났다. 이러한 결과를 통해서 적절한 사전시각단서의 활용과 시선행동 전략에 대한 지각기술훈련이 선수들의 타구 예측능력에 긍정적인 영향을 준다고 할 수 있다. This research was to determine whether the anticipatory skill of national level badminton players can be better improved by perceptual skill training. For this study, eight (4 males and 4 females) Korea national badminton players participated voluntarily in this experiment. Previous study combined the temporal and spatial occlusion paradigms to ascertain which key stimuli badminton players use for anticipating the direction of forehand smash. The main study then evaluated a program for perceptual skill training; 200 video clips of forehand badminton smash played by national players were shown from the view of the returning player. This was followed by 8 weeks of training (two times a week, 30 minute unit).The result of the perceptual training showed that there has been a significant improvements in response time of racket and knee, and tracking speed of eye movement to shuttle after impact. There was a significant differences in visual fixation time on shuttle, upper-body, and arm area between before and after training. Tracking speed of eye movement to shuttle after impact was also faster after training. These results mean that perceptual skill training effectively improved anticipatory skill. This study confirms that perceptual skill training have effects on national level badminton players. Well-designed visual perception skill training is needed to enhance effectively attention control ability during the game and anticipation ability of players to search "information-rich areas" in proper time.

60稅 以上 老人의 日常生活關聯 運動機能의 評價 : 운동을 장기간 동안 습관화하는 노인을 중심으로 하여

The purpose of present study was to investigate characteristics of functional fitness reflecting daily living in Korean active elderly. Eighty nine older people in habitually playing Badminton (age range 60 to 82 years) and physically active volunteered for this study. The functional fitness items represent body composition (ponderal index), cardiovascular endurance (800 m walk), flexibility (sit and reach), muscular strength/endurance (arm curl), coordination (soda pop), and dynamic balance/agility (agility course). To ensure measurement consistency, the same tester conducted the same measurements. The testing apparatuses were calibrated prior to all testing sessions. The results of physical characteristics and functional fitness test are expressed as mean values standard deviations. Each 6 functional fitness tasks representing activity of daily living had to demonstrate a significant correlation with age in our preliminary analyses. In order to reduce the 6 items to a single score, the correlation matrix for the 6 items was subjected to principal component analysis. The main idea of this analysis is to reduce the dimensionality of a data set, which consists of a large number of interrelated variables, while retaining as much as possible the variation present in the data set. The first principal component was used as the best single descriptor of total daily living-related physical fitness tasks. The first principal component scores were computed for each subject. In summary, data for this was considered useful in assessing functional fitness of daily living in the elderly people.

The purpose of this study was to analyze men's single game using stroke direction of Korean national badminton men's player. Six games with 5 foreign top badminton single game players and six games with 4 Korean badminton single game players were analyzed using video tape. The results were as follows: Korean players showed the tendencies that they tried to stroke more under clear than hairpin against short service. They tried to stroke more smash than clear against long service during the single game. Korean players showed the tendencies that they tried to stroke more back area than hairpin in the front area against hairpin of foreign player. But Korean and foreign players showed the tendencies that they tried to stroke more hairpin than under clear against drop shot. Both Korean and foreign players showed the tendencies that they tried to stroke more cutting than long receive against smash. In conclusion, Korean single game players must try more accurate and diverse net playings. The Korean players showed we weak points in the stroke directions in comparison with the top players in the world and these weak points can be eliminated through science-based training.
