Abstract

The aim of this study was to identify the contribution of the Soleus and Gastrocnemius (Gastroc) muscles' forces to anterior cruciate ligament (ACL) loading during single-leg landing. Although Quadriceps (Quads) and Hamstrings (Hams) muscles were recognized as the main contributors to the ACL loading, less is known regarding the role of ankle joint plantarflexors during landing. Eight healthy subjects performed single-landing tasks from 30 and 60. cm heights. Scaled generic musculoskeletal models were developed in OpenSim to calculate lower limb muscle forces. The model consisted of 10 segments with 23 degrees of freedom and 92 lower body muscle-tendon units. Knee joint reaction forces were ..
