Which of the following muscle is used in normal walk during stance and swing?

Normal walking constitute of stance phase (when at least one leg is in contact with the ground) and swing phase (when the leg is in air). Together, the soleus, gastrocnemius, and plantaris act as powerful plantar flexors of the ankle joint. They provide the main forward propulsive force in walking and running by using the foot as a lever and raising the heel off the ground. Ref: Clinical Anatomy By Regions By Richard S.
