摘　　要：利用结合运动追踪技术和肌肉骨骼模型的OpenSim生物力学仿真方法,建立下肢肌肉-骨骼模型,并采用基于动态优化的方法计算下肢肌肉的即时受力,对跟腱负荷和肌肉-跟腱单位的拉伸进行生物力学分析。结果显示:比目鱼肌和腓肠肌的肌肉-跟腱单位在跨栏和短跑运动时产生拉伸形变,比目鱼肌形变差异分别为0.031 mm和0.016 mm;腓肠肌形变差异分别为0.031 mm和0.021 mm;跨栏和短跑运动中,跟腱负荷分别为(4066.91±322.56)N和(3 361.76±194.01)N。该研究可以为跨栏运动跟腱伤病的预防提供科学依据,为进一步的跟腱损伤研究奠定基础。Using the biomechanical simulation method based on OpenSim software which combines motion capture and muscle-bone model techniques, this study built a lower extremity model. The dynamic optimization method was adopted to calculate the muscle force and biomechanical analysis was also used on Achilles tendon （AT） loading and muscle-tendon unit （MTU） strain. The results indicated that soleus MTU and Gastrocnemius MTU were tensile and had deformation during hurdling and running. Soleus MTU deformation difference were 0.031 mm and 0.016 ram; Gastrocnemius MTU deformation difference were 0.031 mm and 0.031 ram; Achilles tendon loading in hurdling and running were （ 4 066.91＋322.56） N and （3 361.76＋194.01 ）N. This study can provide a scientific basis for the prevention of Achilles tendon injury in hurdling and further the study on Achilles tendon injury mechanism.
