남자 고등부 양궁선수의 슈팅동작 시 상지분절에 대한 운동역학적 분석

Abstract

The purpose of this study was to provide basic data to secure the consistency of shooting skills through thekinetic analysis about shooting motion targeting 6 male high school archery players. Study results about kineticvariables are as follows. First, First, times in follow-through phase from release to delivery were identified to be 0.12±0.06 seconds. Second, the angle of right shoulder joint was identified to be larger at release point compared with at deliverypoint and the angle of left shoulder joint didn``t show thbe ig difference both at release point and deliver ypoint. Second, the angle of right shoulder joint was identifie dto be larger at release point compared with a tdelivery point and the angle of left shoulder joint didn``t show the big difference both at release point and deliverypoint. Third, working ranges in follow-through section were 17.52±13.47° at right hand side and 0.13±6.41° atleft hand side, which showed big working ranges in right shoulder joint. Fourth, angles of right elbow joint showed 34.14±11.97° at release point and 22.14±5.22° at delivery point. And, working range of elbows showed 5.59±2.67°. Fifth, average integrated EMG (Electromyogram) showed differences in all right Trapezius, biceps brachii ,deltoids and latissimus dorsi muscle and showed higher the EMG valuses in the order of deltoids, biceps brachii,Trapezius and latissimus dorsi muscle.
