While climbing stairs in the football stadium, Gary injured his calcaneal tendon (Achilles tendon). Describe the muscles and action(s) that are affected. From what action and activities should he refrain while his tendon heals?
What will be an ideal response?
The calcaneal tendon (Achilles tendon) attaches the two heads of gastrocnemius and soleus muscles to the posterior surface of the calcaneus (heel bone). These muscles form the triceps surae muscle group and are responsible for plantarflexion. While his calcaneal tendon heals, Gary should refrain from activities that plantarflex the injured foot, such as walking stairs, standing on his toes or jumping.
