초록
본 연구는 자가 근막 이완 기법과 PNF 스트레칭이 뒤넙다리근의 근 긴장도 및 유연성에 미치는 영향을 비교 분석하고자 하였다. 대상자는 허리와 엉덩관절, 무릎관절에 질환이나 신경학적 문제가 없는 30명으로, 자가 근막 이완 그룹, PNF 수축-이완 그룹, PNF 유지-이완 그룹으로 나누어 무작위 할당하였다. 연구는 사전-사후 검사 설계로 진행하였으며, 근 긴장도는 Myonometer 를 이용하여 측정하고, 유연성은 능동 무릎 폄(AKE) 및 수동 무릎 폄(PKE) 검사를 통해 평가하였다. 공분산 분석(ANCOVA) 결과, PNF-HR 기법이 근 긴장도에서 주파수(Frequency) 및 경직도(Stiffness)에서 유의미한 감소를 보였으며, 모든 그룹에서 유연성 개선이 확인되었다. 연구 결과, 자가 근막 이완 기법과 PNF 스트레칭은 뒤넙다리근의 근 긴장도 및 유연성을 개선하는 데 효과적이며, 특히 PNF-HR 기법이 가장 두드러진 효과를 나타내어 신경근 조절 및 근육 이완에 중요한기여를 할 수 있음을 시사한다. 본 연구는 스포츠 재활 및 일반인의 신체 기능 향상에 대한 기초 자료로 활용될 수 있을 것이다.
Abstract
This study aimed to compare and analyze the effects of self-myofascial release techniques and PNF stretching on hamstring muscle tone and flexibility. The subjects were 30 individuals without any disorders or neurological issues affecting the lumbar region, hip joints, or knee joints, randomly assigned to self-myofascial release, PNF contract-relax, and PNF hold-relax groups. The study was conducted using a pre-test and post-test design, with muscle tone measured using a Myonometer and flexibility evaluated through Active Knee Extension (AKE) and Passive Knee Extension (PKE) tests. The results of ANCOVA showed that the PNF-HR technique significantly reduced muscle tone in terms of frequency and stiffness, while improvements in flexibility were observed across all groups. The findings indicate that both self-myofascial release techniques and PNF stretching are effective in improving hamstring muscle tone and flexibility, with the PNF-HR technique demonstrating the most pronounced effects, suggesting its significant contribution to neuromuscular regulation and muscle relaxation. This study can serve as a foundational reference for enhancing physical function in sports rehabilitation and among the general population.
