Question:

What is the function of the calf muscles?

Answer:

Function of the Gastrocnemius is to elevate the heel. Function is the Soleus is to raise the heel with the knee bent.

Gastrocnemius

The human body is the entire structure of a human organism and comprises a head, neck, torso, two arms and two legs. By the time the human reaches adulthood, the body consists of close to 100 trillion cells, the basic unit of life. These cells are organised biologically to eventually form the whole body.

Anatomy

In humans and some other mammals, the soleus is a powerful muscle in the back part of the lower leg (the calf). It runs from just below the knee to the heel, and is involved in standing and walking. It is closely connected to the gastrocnemius muscle and some anatomists consider them to be a single muscle, the triceps surae. Its name is derived from the Latin word, "solea," meaning "sandal."

The soleus is located in the superficial posterior compartment of the leg. Not all mammals have a soleus muscle; one familiar species that lacks the soleus is the dog. Soleus is vestigial in the horse.

In humans, the gastrocnemius muscle (/ˌɡæstrɒkˈnmiəs/ or /ˌɡæstrəkˈnmiəs/; Latin, from Greek γαστήρ "stomach" and κνήμη (knēmē) "leg"; meaning "stomach of leg", referring to the bulging shape of the calf) is a very powerful superficial bipennate muscle that is in the back part of the lower leg. It runs from its two heads just above the knee to the heel, and is involved in standing, walking, running and jumping. Along with the soleus muscle it forms the calf muscle. Its function is plantar flexing the foot at the ankle joint and flexing the leg at the knee joint. In a 1967 EMG study, Herman and Bragin concluded that its most important role was plantar flexing in large contractions and in rapid development of tension.

The gastrocnemius is located with the soleus in the posterior (back) compartment of the leg. The lateral head originates from the lateral condyle of the femur, while the medial head originates from the medial condyle of the femur. Its other end forms a common tendon with the soleus muscle; this tendon is known as the calcaneal tendon or Achilles Tendon and inserts onto the posterior surface of the calcaneus, or heel bone.


The triceps surae (/ˈtrsɛps ˈsjʊər/) (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 posterior leg, commonly known as the calf muscle.

Heel Calf Gastro-

Calf raises are a method of exercising the gastrocnemius, tibialis posterior and soleus muscles of the lower leg. The movement performed is plantar flexion, aka ankle extension.

Locomotor effects of shoes describes how physical characteristics or components of shoes influence the locomotion neuromechanics of a person. Depending on the characteristics of the shoes, the effects are various, ranging from alteration in balance and posture, muscle activity of different muscles as measured by electromyography (EMG), and the impact force. There are many different types of shoes that exist, such as running, walking, loafers, high heels, sandals, slippers, work boots, dress shoes, and many more. However, a typical shoe will be composed of an insole, midsole, outsole, and heels, if any. In an unshod condition, where one is without any shoes, the locomotor effects are primarily observed in the heel strike patterns and resulting impact forces generated on the ground.
