The Effect Of Soleus Fatigue During Sidestep Cutting Maneuvers: Implications For The Acl, Michael William Ciesa

Browse all Theses and Dissertations

The soleus muscle is a monoarticular plantarflexor composed slow-twitch fatigue-resistant muscle fibers. Through its attachment to the proximal tibia, contraction of the soleus muscle in a closed kinetic chain (when the foot is planted) produces a posterior pulling force on the posterior proximal tibia. The anterior cruciate ligament (ACL) is responsible for preventing anterior displacement of the tibia relative to the femur. Through the production of a posterior pulling force on the tibia, soleus muscle contraction in a closed kinetic chain could help reduce strain on the ACL. Fatigue is a neuromuscular phenomenon that can alter biomechanical strategies during athletics …
