腿筋限制前十字韧带 (ACL) 的负荷，这些肌肉的神经肌肉控制对于膝关节的动态稳定性至关重要。之前曾报道过机电延迟（EMD）和发力率（RFP）方面的性别差异，并将其归因于肌腱刚度（MTS）的差异。这些特征定义了对关节扰动的神经力学反应，这些特征的性别差异可能导致女性 ACL 损伤风险更大。然而，尚不清楚腘绳肌中是否存在这些差异，并且 MTS 和神经力学功能之间的关系尚未得到直接评估。对无 ACL 损伤史的 20 名男性和 20 名女性进行了腿筋 MTS、EMD、产生 50% 峰值力所需的时间 (Time50%) 和 RFP 评估。 EMD 在不同性别之间没有显着差异 (p=0.788)。然而，MTS（p
The hamstrings limit anterior cruciate ligament (ACL) loading, and neuromuscular control of these muscles is crucial for dynamic knee joint stability. Sex differences in electromechanical delay (EMD) and rate of force production (RFP) have been reported previously, and attributed to differences in musculotendinous stiffness (MTS). These characteristics define the neuromechanical response to joint perturbation, and sex differences in these characteristics may contribute to the greater female ACL injury risk. However, it is unclear if these differences exist in the hamstrings, and the relationship between MTS and neuromechanical function has not been assessed directly. Hamstring MTS, EMD, the time required to produce 50% peak force (Time50%), and RFP were assessed in 20 males and 20 females with no history of ACL injury. EMD did not differ significantly across sex (p=0.788). However, MTS (p
