However, among all the skeletal muscles, the gastrocnemius was probably the most suitable muscle to examine immobilization-induced deconditioning and passive shortening.
This exercise focuses on the hamstrings but also involves the gastrocnemius muscles.
For example, during a static stretch of the gastrocnemius (calf muscle) the participants should continue to swing the arms, or alternate active movement and static stretching.
As the foot strikes the ground, the toes are pointed - the ankle is extended by contraction of the gastrocnemius - whilst the knee is also extended.
The gastrocnemius muscle and soleus muscle, via the Achilles tendon, function as the chief plantar flexors of the ankle joint.
