Abstract

The purpose of this study was to investigate propulsive time and kinematic variables on the three different kinds of the basketball wheelchairs in each play position for eight abled basketball wheelchair players. Kinematic data were collected by a video camera for two-dimensional analysis. The wheelchairs for the guard position showed the fastest in total propulsive time. The wheelchairs for the center position revealed the slowest in the phase of the change of the direction. The wheelchair for the guard position which shows fast movement velocity demonstrated closer hand contact with TDC(Top Dead Center). The wheelchair for the center position revealed the largest extension of the elbow and flexion of the trunk at handrim contact. The wheelchair for the guard position which has the lowest seat height presented larger elbow angle and trunk angle. The wheelchair for the guard position produced more fast trunk angular velocity than the wheelchair for other positions.

본 연구의 목적은 정상인 휠체어 농구 선수 8명을 대상으로 추진 및 방향전환 동작의 소요시간 측정 및 운동학적 분석을 통하여 포지션별 농구용 휠체어가 추진동작에 미치는 효과를 규명하는데 있다. 포지션별(포드, 센타, 가드) 휠체어의 한 주기(핸드림 접촉에서 다음 핸드림 접촉까지)를 2차원 DLT 방식을 이용하여 구하고자 하는 변인을 산출하였다. 가드용 휠체어는 직선 구간 및 방향전환 구간 모두에서 가장 빠르게 나타났으며, 센타용 휠체어는 방향전환 구간에서 제일 느린 것으로 나타났다. 이동 속도가 가장 빠른 가드용 휠체어는 손이 TDC(Top Dead Center)에 더 가깝게 접촉하며, 더 오랫동안 핸드림에 힘을 가해서 추진하며, 분당 추진빈도는 가장 적은 것으로 나타났다. 반면에 센타용 휠체어는 손이 TDC에서 가장 멀리 접촉하며, 가장 짧은 범위에서 핸드림에 힘을 가해서 추진하는 것으로 나타났다. 가드용 휠체어는 핸드림 접촉시 팔꿈치를 가장 많이 굽히고 몸통을 가장 많이 세우며, 센타용 휠체어는 핸드림 접촉시 팔꿈치를 가장 많이 펴고 몸통을 많이 굽히며 핸드림 이지시 가드용 휠체어에 비해 팔꿈치를 많이 펴는 것으로 나타났다. 휠체어 추진시 좌석의 높이가 가장 낮은 가드용 휠체어는 포드용 및 센타용 휠체어보다 팔꿈치 및 몸통각의 범위가 가장 큰 것으로 나타났다. 몸통 최대 각속도에서 가드용 휠체어는 다른 휠체어와 비교해서 가장 큰 값을 나타냈다.
