초록
본 연구는 숙련도에 따른 불가리안 스플릿 스쿼트 동작의 운동학적 변인 차이를 확인하기 위해 숙련자 10명과 비숙련자 10명을 대상으로 실험을 진행하였다. 3D 동작 분석을 통해 불가리안 스플릿 스쿼트 동작을 관찰하였으며 숙련자와 비숙련자 그룹의 체간, 고관절, 슬관절, 족관절의 가동범위를 비교하였다. 이를 통해 얻은 결과는 다음과 같다. 첫째, 슬관절 관상면 움직임에서 비숙련자는 숙련자보다 외반이 더 크게 나타났다. 둘째, 고관절 수평면 움직임에서 비숙련자는 숙련자보다 내회전이 더 크게 나타났다. 셋째, 체간, 족관절에서 숙련자와 비숙련자의 가동범위는 유의한 차이가 나타나지 않았다. 본 연구 결과는 향후 운동 초심자의 불가리안 스플릿 스쿼트 수행 시 슬관절의 과도한 외반 스트레스에 주의해야 할 필요가 있다는 것을 보여주고 있으며 고관절 근력 강화를 통해 이를 조절할 수 있음을 암시한다
Abstract
In this study, an experiment was conducted with 10 skilled and 10 unskilled persons to confirm the difference in kinematic variables of the Bulgarian Split Squat according to skill level. We observed Bulgarian Split Squat through 3D motion analysis and compared the range of motion of the trunk, hip, knee, ankle of skilled and unskilled groups. The results are as follows. First, in the frontal movement of the knee joint, the unskilled had a larger valgus than the skilled ones. Second, in the horizontal movement of the hip joint, the unskilled had a larger internal rotation than the skilled ones. Third, there was no significant difference in the range of motion of the skilled and unskilled in the trunk and ankle joints. This study shows that it is necessary to pay attention to excessive valgus stress of the knee joint when performing the Bulgarian Split Squat by a beginner in the future and implies that this can be controlled through strengthening the hip joint strength.
