Abstract

The flexors and extensors of the knee joint are essential for maintaining body stability. The purpose of this study was to investigate the correlation between the isokinetic parameters of the knee flexor and extensor muscles and the function of the lower extremity muscles. Twenty-two healthy adults participated in this study. The time to peak torque (TTP), acceleration time (AT), and peak torque (PT) of the knee flexor and extensor muscles were measured. A 20m sprint, Sargent jump, one leg hop test, and side shuffle were measured to evaluate lower extremity function. The correlation between each variable was analyzed using Pearson correlation coefficient. PT of the knee flexor showed a significant correlation with single leg hops and 6M hops in a single leg. PT of knee extensors was found to be significantly correlated with Sargent jumps and triple hops. Based on the results of this study, we suggest that the strength of the knee flexor and extensor muscles has the potential to be used to predict lower extremity function.

무릎관절의 굽힘근과 폄근은 신체의 안정성을 유지하는 데 필수적이다. 본 연구는 무릎 굽힘근 및 폄근의 등속성 파라미터와 하지 근육 기능의 상관관계를 조사하고자 하였다. 22명의 건강한 성인이 본 연구에 참여하였습니다. 무릎 굽힘근 및 폄근의 time to peak torque (TTP), acceleration time (AT), peak torque (PT)가 측정되었습니다. 하지 기능 평가를 위해 20m sprint, Sargent jump, one leg hop test, and side shuffle이 측정되었습니다. 각 변수들 간의 상관관계가 Pearson correlation coefficient을 사용하여 분석되었습니다. knee flexor의 PT는 single leg hops and 6M hops in a single leg와 유의한 상관관계를 나타내었다. knee extensors의 PT는 Sargent jumps and triple hops와 유의한 상관관계가 갖는 것으로 발견되었다. 본 연구 결과를 기반으로 무릎 굽힘근 및 폄근의 근력이 하지 기능을 예측하는 데 사용될 수 있는 가능성이 있음을 시사한다.
