基于 OpenSim 技术的跨栏跟腱仿真分析

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 mm ;Gastrocnemius MTU deformation difference were 0.031 mm and 0.031 mm;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.
