This study aimed to determine whether changes in hamstrings passive and active shear modulus after a warmup protocol are correlated. Twenty males without a history of hamstring strain injury participated. Muscle shear modulus was assessed using ultrasound-based shear wave elastography at rest and during isometric contractions at 20% of maximal voluntary isometric effort before and immediately after a warmup protocol. Changes in passive shear modulus did not seem to be associated with changes in active shear modulus. The results of this study suggest that changes in passive and active hamstring shear modulus are not associated after a standardized warmup intervention.
本研究旨在确定热身方案后腘绳肌被动和主动切变模量的变化是否相关。 20 名无腘绳肌拉伤史的男性参与了本研究。在热身方案前后，使用基于超声的剪切波弹性成像技术，在休息时和在最大自主等长收缩的 20%时，对肌肉切变模量进行评估。被动切变模量的变化似乎与主动切变模量的变化无关。本研究结果表明，在标准化热身干预后，被动和主动腘绳肌切变模量的变化没有关联。
