OBJECTIVES
This study aimed to compare the effects of myofascial release (MFR) and hot pack therapy (HPT) on fascial gliding and flexibility of the vastus lateralis muscle.
METHODS
Three treatments were applied to the left vastus lateralis muscles of each participant (12 healthy males): MFR for 4 min, superficial HPT for 10 min, and superficial HPT for 20 min. Deep fascial motion was measured by B-mode ultrasound, whereas muscle stiffness was measured by real-time elastography (RTE) and a durometer before and after the interventions.
RESULTS
Only MFR resulted in changes in both deep fascial motion and muscle stiffness measured by RTE. Durometer-measured muscle stiffness revealed changes following both MFR and 20-min HPT but not 10-min HPT.
CONCLUSIONS
HPT may produce only superficial effects. Because MFR improved all measured parameters, continuous stretching and pressure are probably important for improving fascial gliding and flexibility of the vastus lateralis muscle.
目的
本研究旨在比较肌筋膜放松（MFR）和热敷疗法（HPT）对股外侧肌筋膜滑动和柔韧性的影响。
方法
对每位参与者（12名健康男性）的左侧股外侧肌进行三种治疗：MFR 4分钟、浅表HPT 10分钟和浅表HPT 20分钟。干预前后通过B型超声测量深部筋膜运动，通过实时弹性成像（RTE）和硬度计测量肌肉僵硬度。
结果
只有MFR导致RTE测量的深部筋膜运动和肌肉僵硬度均发生变化。硬度计测量的肌肉僵硬度显示，MFR和20分钟HPT后均有变化，但10分钟HPT后无变化。
结论
HPT可能仅产生浅表效应。由于MFR改善了所有测量参数，持续拉伸和压力可能对改善股外侧肌的筋膜滑动和柔韧性很重要。
