Abstract

The purpose of this study is to analysis the horizontal distance of COM and COP and the movement patterns of COM and COP during the badminton high-clear of woman middle school student. The select variables used in the statistical analyses(independent sample T-test) were the horizontal distance of COM and COP at (E4), and the maximum COM displacement of the back-, forward-, whole-swing phases between expert and novice groups. Based on the results in this study, it was concluded that: First, expert group showed the shorter horizontal distance between COM and COP in anteroposterior axis (X-axis) at Event 4 compared to the novice group. Second, expert group dominantly used COM vertical movement while novice group actively used COM horizontal movement during the badminton high-clear stroke.

본 연구의 목적은 배드민턴 여자 중학생 전문선수(10명)와 방과 후 배드민턴 수업에 참여하는 일반학생(10명)의 하이클리어 동작 시 COM과 COP의 수평거리, 그리고 COM과 COP의 이동패턴의 차이를 비교 분석하는데 있다. 두 그룹 간 하이클리어 스트로크 이후 착지 시점(E4)에서 COM과 COP의 X축과 Y축에서의 수평거리와 백스윙, 포워드스윙, 스윙전체의 X축, Y축, 그리고 Z축에서 COM의 최대이동범위의 차이를 비교하기 위해 독립표본 T-test를 실시한 결과, 첫째, 하이클리어 스트로크 임팩트 이후 착지 시점(E4)에서 여자 중학생 전문선수는 전후방향(X축)에서 COM와 COP지점이 일반학생에 비해 매우 가깝게 위치하였다. 둘째, 전문선수는 COM의 수직움직임, 일반선수는 COM의 수평움직임을 적극적으로 활용하였다.
