배드민턴 技術動作 分析

Abstract

In The badminton game which begins with a service, the drive, smash, and push motion could be regarded as making a score. I analyzed the transfer track, distrance, velocity, angularity, and angular velocity of the racket and upper limbs. In older to carry out this analysis, three man players who belong to the Korea Badminton Association were selected, and their motions were photographed by 16㎜ high speed cameral (48 Frame/sec). The result of analyzing these films were as follows. A. The transfer track of segments in upper limbs. 1. In drive motion, the greater tack swing, longer resistance arm, and more enough follow throw can make the efficiency of force stronger. So B player was found to make a greater back swing than other players. And he was found to transfer back and forward swing longer to have high speed. Also A player was found to transfer moment arm longer in impacts to have an efficient technique. 2. In smash motion, all of then were found to make a follow throw with raised racket and upper limbs, and were found to show longer moment arms in impacts. In particular, A player and C player were found to make their tracks near circle. So they could show efficient smash motions. 3. In push motions, their wrists in back swing were found to be hyperextended, and their wrist joints were found to be flexed. And their strong snaps with straight upper limbs were found in impacts. So the velocity of shuttle cock became very speedy. B. The transfer distance of segments in upper limbs. 1. In drive motion, all of three players were found to be trans ferred racket head and elbow averagely longer (195.6cm, 78.3cm) in follow throw, md wrist and shoulder longer (68.7cm, 53.7cm) in back swing. 2. In smash motion, racket head was found to be transfered longer (3.46cm) in follow throw, and wrist, elbow, and shoulder longer (193.6cm, 211.0cm, 161.6cm) in back swing. 3. In push motion, racket head, wrist, and shoulder were found to be transfered longer (127cm, 83.7cm, 87cm) in follow throw, and elbow longer (58.3cm) in forward swing. C. The transfer velocity of segments in upper limbs. 1. In drive motion, all of them were found to transfer racket head, wrist, and shoulder averagely faster (16.01m/sec, 2.87m/sec, 1.20m/sec) in forward swing, and elbow faster (3.83m/sec) in follow throw. 2. In smash motion, racket head md wrist, were found to be transfered faster (14.15m/sec, 3.17m/sec) in forward swing, and elbow and shoulder faster (3.68m/sec, 1.19m/sec) in follow throw. 3. In push motion, racket head, wrist, and elbow were found to be transfered faster (13.06m/sec, 1.80m/sec, 2.79m/sec) in forward swing , and shoulder faster (1.64m/sec) in follow throw. D. The angularity change of segments in upper limbs. 1. In drive motion, all of three players were found to extend their wrists averagely wider (166˚) in impacts, and elbow and shoulder wider (105˚, 46˚) in back swing. 2. In smash notion, wrist and elbow were found to be extended wider (162˚, 151˚) in back swing, and shoulder wider (143˚) in follow throw. 3. In push motion, every part of upper limbs was found to be extended wider (72˚, 70˚, 53˚) in back swing. E. The angular velocity change of segments in upper limbs. 1. In drive motion, all of three players were found to show every segment averagely faster (28.06Radian/sec, 15.36Radian/sec, 2.84Radian/sec) in impacts. 2. In smash motion, every part of upper limbs was found to be faster (22.69Radian/sec, 15.09Radian/sec, 2.84Radian/sec) in impacts. 3. In push motion, wrist was found to be faster (7.23Radian/sec) in impacts, and, elbow and shoulder faster (4.5Radian/sec, 2.57Radian/sec) in follow throw.;배드민턴競技는 서어브로 始作하여 最終打로 득점과 연결되는 것은 드라이브(Drive), 스매시(Smash), 푸시(Push) 등이라고 볼 수 있다. 本 硏究는 이리한 技術動作을 할 때 라켓 및 상지관절의 移動軌跡, 距離, 速度, 角度, 角速度등을 分析하기 위하여 협회에 등록되어 있는 일반 및 대학부 선수중 남자 3명을 대상으로 16mm 촬영기 (48 Frame/sec)로 고속도 촬영하여 映像分析法에 의해 分析한 結果, 다음과 같은 結論을 얻었다. A. 上脂 各 分節의 移動軌跡 1. 드라이브 技術을 試圖할 때는 백스윙 동작을 크게 하며 圓周(Circular)를 그리고 저항팔(Resistance Arm)을 크게하여 임팩트 한후 충분한 할로우드로우를 해야 힘의 능률을 크게 할 수 있는데 분석 결과 B선수는 타 선수 보다 백 스윙 동작이 커 임팩트시 힘을 加하는 거리를 길게하여 큰 속도를 내기 위한 동작이었고, A선수는 임팩트시 저항팔을 길게하고 있어 효율적인 기술시도를 하고 있었다. 2. 스매시 試圖시에는 각 선수 모두 활로우드로우에서 라켓 및 상지 분절이 위로 올라가며 작용팔을 길게 하여 임팩트되고, 특히 A선수와 C선수의 전체 軌跡이 원에 가까와 효율적인 스매시를 하고 있었다. 3. 푸시 技術試圖시에는 백스윙동작에서 순간적으로 주관절을 과신전시키고 엘보관절(Elbow)을 굴곡한 후 임팩트시에 상지관절을 펴고 손목의 스냅만을 이용했기 때문에 샤틀의 비행속도를 빠르게 해 주고 있었다. B. 上脂 各 分節의 移動距離 1 .드라이브 試圖시 피험자들의 평균치 비교는 라켓해드와 팔굽에서는 활로우드로우가 195.6㎝, 78.3㎝로 가장 길었으며 손목과 어깨에서는 백스윙에서 68.7㎝, 53.7㎝로 가장 길게 나라났다. 2. 스매시 試圖시 라켓해드는 활로우 드로우에서 3.46㎝, 손목, 팔굽, 어깨는 백스윙에서 각각 193.6㎝, 211.0㎝, 161.6㎝로 가장 길게 나타났다. 3. 푸시 試圖시 가장 길게 이동한 구간은 라켓해드, 손목, 어깨에서 활로우 드로우가 127㎝, 83.7㎝, 87㎝이고 팔굽에서는 훠워드 스윙이 58.3㎝로 가장 길게 나타났다. C. 上肢 各 分節의 移動速度 1. 드라이브 試圖시 제일 빠르게 나타난 구간은 라켓해드, 손목, 어깨에서는 훠워드스윙에서 16.01 m/sec, 2.87m/sec, 1.20m/sec이었고, 팔굽은 활로우 드로우에서 3.83m/sec로 가장 빠르게 나타났다. 2. 스매시 試圖시 제일 빠르게 나타난 구간은 라켓해드, 손목이 훠워드스윙에서 14.15m/sec, 3.17m/sec였고, 팔굽과 어깨는 활로우드로우에서 3.68 m/see, 1.19m/sec로 가장 빠르게 나타났다. 3. 푸시 試圖에서는 라켓해드, 손목, 팔굽이 훠워드스윙에서 13.06m/sec, 1.80m/sec, 2.79m/sec였고, 어깨는 활로우드로우에서 1.64 m/sec로 가장 빠르게 나타났다. D. 上肢 各 分節의 角度變化 1. 드라이브 試圖시 손목에서는 임팩트에서 165°, 팔굽과 어깨는 백스윙에서 105°, 46°로 가장 넓게 나타났다. 2. 스매시는 손목, 팔굽이 백스윙에서 162°, 151°이고, 어깨는 활로우드로우에서 143°로 가장 넓게 나타났다. 3. 푸시는 各各 백스윙에서 72°, 70°, 53°로 제일 넓게 나타났다. E. 上肢 各 分節의 角速度變化 1. 드라이브 試圖시는 손목, 팔굽, 어깨에서 임팩트시에 28.06 Radian/sec, 15.36 Radian/sec, 2.84 Radian/sec로 가장 빠르게 나타났다. 2. 스매시는 손목, 팔굽, 어깨에서 임팩트시에 22.69 Radian/sec, 15.09 Radian/sec, 13.40 Radian/sec로 가장 빠르게 나타났다. 3. 푸시는 손목에서 임팩트시에 7.23 Radian/sec이고 팔굽, 어깨는 활로우 드로우에서 4..51 Radian/sec, 2.57 Radian/sec로 제일 빠르게 나타났다.
