초록

이 연구의 목적은 올림픽 라운드기록에 영향을 미치는 운동학적인 요인을 구명하는 것이다. 대상자는 K 대학교의 숙련된 양궁선수 8명(나이: 20±1세 무게: 77±13kg, 신장: 178±5cm)이 참여하였으며, 올림픽 라운드 상황과 동일조건에 준하여 개인별 12회 총 72회의 슈팅을 7대의 고속 적외선 디지털 카메라(MCU-240)로 촬영하였다. 그 결과 첫째, 기록별 견관절의 평균 각속도가 기록에 미치는 영향은 통계적으로 유의한(p=.65<.10) 것으로 나타났으며 회귀식은 y=-0.0637x +17.074이고 결정계수는 R2=0.874이었다. 둘째, 견관절의 평균 각속도가 약 120°/sec.에서 고득점이 분포하였다. 셋째, 견관절의 평균 각속도가 느려질수록 기록이 크게 나타났다. 결론적으로 회귀식은 정의역, 110°/sec.< x <160°/sec.에서 견관절 평균 각속도가 낮을수록 기록이 증가하였고 약 87%의 설명력을 가졌다.

C. K. HAH, and J. H. YI, Evaluation on Kinematic Factors Affecting Scores of Olympic Round Game during the Follow Through in Archery. Korean Journal of Sport Biomechanics, Vol. 18, No. 1, pp. 227-234, 2008. The purpose of this study was to investigate kinematic factors affecting scores of Olympic Round Game during follow through which was basic and important in archery. For this study, 8 male archers(20±1 yrs ,77±13 kg, 178±5 cm) of K university participated in the experiment. The seven infrared cameras (Qualisys MCU-240) were used to acquire raw data, and analyzed with Matlab6.5 for variables. The results were as follows: First, angular average velocity of shoulder joint affecting scores was a statistical significance (p=.65, p<.10), and the regression equation was y = - 0.0637 x + 17.074, and determinant coefficient R2 = 0.874 respectively. Second, good records was acquired about 120°/sec. of angular average velocity of shoulder joint. Third, as records was lower and lower, a peak-pulse on angular average velocity of shoulder joint was great during follow through. In conclusion, the record was greater as angular average velocity of shoulder joint was smaller and smaller from 110°/sec. to160°/sec. It is suggested that a lower angular average velocity of shoulder joint and no peak-pulse may obtain good scores during follow through.
