The triceps surae (from Latin caput and sura. "three-headed calf [muscle]") is a pair of muscles located at the calf - the gastrocnemius and the soleus. These muscles both insert into the calcaneus, the bone of the heel of the human foot, and form the major part of the muscle of the back part of the lower leg, commonly known as the calf muscle.
The triceps surae is innervated by the tibial nerve, specifically, nerve roots L5–S2.
This injury happens during acceleration or changes in direction. The torn calf muscle may spasm, and contract forcefully. The toes may also point down (Foot drop). Bruises can show up in the leg, foot and ankle due to pooling of blood from internal bleeding. It may take some time for the bruises to occur, from hours to days depending upon where the tear occurred. The circumference of the leg will most certainly increase.
This injury may take several months to heal. It is important not to continue the exercise if muscle is torn, as internal bleeding is taking place. See a doctor immediately after the muscle is torn to begin rehabilitation.
