跟腱（AT）由比目鱼肌（SOL）、腓肠肌外侧头（LG）和内侧头（MG）产生的3个亚腱组成。虽然最近的人体研究表明AT内的差异位移，这些位移并不归因于特定的子肌腱。我们测试的假设，SOL和LG子筋显示不同的位移和应变在SOL，LG和MG激励的各种组合。运动的结，缝合到SOL和LG亚肌腱的12只Wistar大鼠，录像，而肌肉内刺激和踝关节扭矩进行了评估。在不同条件下，仅刺激SOL时，跖屈力矩最小（P
Achilles tendon (AT) comprises of 3 subtendons arising from the soleus (SOL) and the lateral (LG) and medial (MG) heads of the gastrocnemius muscle. While recent human studies show differential displacement within AT, these displacements have not been attributed to specific subtendons. We tested the hypothesis that the SOL and LG subtendons show differential displacement and strain during various combinations of SOL, LG, and MG excitations. Movement of knots, sutured onto SOL and LG subtendons of 12 Wistar rats, was videotaped, while the muscles were stimulated intramuscularly and ankle torque was assessed. When SOL only was stimulated, the plantar flexion torque was the smallest among the different conditions (P
