여자 중․고등학교 양궁선수의 슈팅 기술에 대한 운동역학적 분석

Abstract

The purposes of this study were to investigate selected biomechanical variables of the shooting motion for female middle and high school players and to provide useful data to coaches for instructing the shooting skill in archery. Three middle school and four high school archers participated in this study. Biomechanical data was collected via three digital cameras, surface electromyography (EMG) and two AMTI force plates. Each participant shot 12 arrows consisting of two ends (six arrows per end). The results of this study were as follows: 1) in the drawing phase, both groups had a long average drawing time with a relatively large standard deviation; 2) generally, Z axis forces in middle school participants during the whole phase was shown to be greater than in high schoolers; 3) for both groups, X and Y axis forces were relatively consistent demonstrating controlled balance throughout the whole phase; 4) in the drawing phase, the range of center of pressures for X axis and Y axis forces in middle schoolers were more varied than those in high schoolers; 5) the trapezius muscle activity for middle school participants during the release phase was much greater than in the throwing phase.
