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.
