Abstract

The purpose of this study was to analyze the correlation between passive ankle movement range and knee joint kinetic variables during squat movement. In this study, a total of 27 subjects participated in this study, 19 men and 8 women, who had no history of the musculoskeletal system of the lower extremity. To verify the correlation between the ankle joint flexibility and the knee joint kinetic variables during deep squat, it was performed pearson's correlation coefficient and variables showing statistically significant correlation were performed by simple regression analysis at a significant level of α .05. Through this study, the relationship between the peak joint moment and joint reaction force factors that determine ankle joint flexibility and knee joint pressure was confirmed. Therefore, when applying an exercise that can generate a lot of load on the knee joint such as deep squats during strength training, checking the degree of flexibility of the ankle joint among physical characteristics to the individual may reduce the stability of the body and the risk of injury to the knee joint. It is expected to be helpful in setting the intensity of exercise that can be done.

본 연구의 목적은 딥 스쿼트 동작 시 발목 관절 유연성이 무릎 관절의 운동역학적 요인들간의 관련성을 분석하는데 있었다. 본 연구는 최근 1년간 하지 근골격계 병력이 없는 성인 남성 19명과 여성 8명이 연구대상자로 참여하였다. 딥 스쿼드 시 발목 관절 유연성과 하지 관절의 운동역학적 요인들과 상관관계를 검증하기 위해 pearson의 적률상관계수(pearson's correlation coefficient)를 이용하였고(SPSS 24.0, Armonk, NY, USA), 통계적으로 유의미한 상관성을 나타낸 변인들은 단순회기분석(simple regression analysis)을 실시하였으며, 유의 수준은 .05로 설정하였다. 본 연구를 통해 발목 관절 유연성과 무릎 관절의 압력을 결정하는 최대 관절모멘트와 관절반발력 요인들 간의 관련성을 확인할 수 있었다. 그러므로 근력 트레이닝 시 딥 스쿼트와 같은 무릎 관절에 많은 부하를 발생시킬 수 있는 운동을 적용할 때 개인에 신체적 특성 중 발목 관절의 유연성의 정도를 확인하는 것은 신체의 안정성과 무릎 관절의 상해 위험성을 감소시킬 수 있는 운동 강도를 설정하는데 도움이 될 수 있을 것으로 기대한다.
