本研究的主要目的是确定髋关节运动范围和硬度的个体差异是否以及在多大程度上可以解释腘绳肌肌肉弹性的差异。对 21 名年轻男性在膝关节伸展位置从解剖位置到最大髋部屈曲角度的单侧被动髋部屈曲过程中，评估了股二头肌、半腱肌和半膜肌的髋部伸展扭矩和剪切模量（弹性测量）。通过使用超声剪切波弹性成像来量化肌肉剪切模量。最大髋关节屈曲角度与每块肌肉的剪切模量负相关（-0.750
The main purpose of the present study was to identify whether and to what extent the individual differences in range of motion and stiffness of the hip joint can account for that in muscle elasticity of the hamstring. Hip extension torque and shear moduli (a measure of elasticity) of the biceps femoris, semitendinosus, and semimembranosus were assessed in 21 young males during unilateral passive hip flexion in the knee-extended position from the anatomical position to the individual's maximal hip flexion angle. Muscle shear modulus was quantified by using ultrasound shear wave elastography. The maximal hip flexion angle correlated negatively with the shear modulus of each muscle (-0.750
