Abstract

In this study, we analyzed the balance of the both legs and the kinematic analysis of the upper limb segments and joints during archery shooting and compared the differences according to the scores. 9 K-university elite archery athletes participated. Each archer was asked to shoot 3-shots and 5-ends on a 122 cm target at a distance of 70 m. Seven infrared cameras (Qualisys, sweden) and two force plates (Kistler, Switerland) were used to calculate the upper limb segments and joint movements and the center of pressure (COP). When the archers shot 8 points, range of motion of elbow joint angle on drawing-arm and mediolateral COP range of motion on the left foot were larger than when 9-10 points were shot (p<.05). In order to maintain a high score in the archery game, constant balance is required, and the balance of the left foot supporting the bow during the shooting is an important factor. In addition, minimizing elbow joint movement of the drawing-arm supporting the bow will help stabilized shooting.

본 연구에서는 양궁 슈팅 시 양발의 균형성과 상지 분절 및 관절의 운동학적 분석을 실시하여 점수에 따른 차이를 비교분석 하였다. K대학교 엘리트 양궁선수 9명을 피험자로 선정하였으며, 70 m 거리에서 122 cm 표적지에 각각 3발씩 5엔드를 반복 측정하였다. 7대의 적외선 카메라(Qualisys, sweden)와 2대의 지면반력기(Kistler, Switerland)를 사용하여 상지 분절 및 관절의 움직임과 힘의 작용점(center of pressure [COP])를 산출하였다. 연구결과 양궁 선수가 8점을 쐈을 때, 9-10점을 쐈을 때보다 드로잉 암(drawing-arm)의 팔굽관절 운동범위와 왼발의 좌우 COP 범위가 크게 나타났다(p<.05). 양궁 경기에서 고득점을 유지하기 위해서는 지속적인 균형성이 요구되며, 특히 슈팅하는 순간 활을 지지하는 왼발의 균형성이 중요한 요인으로 작용한다. 또한 활을 지지하는 드로잉 암의 팔굽관절 움직임을 최소화하는 것이 안정적인 슈팅에 도움이 될 것이다.
