The soleus muscle runs along the gastrocnemius muscle and together they insert onto the posterior surface of the calcaneus via the calcaneal tendon. The calcaneal tendon, commonly called the Achilles tendon
Achilles tendon
The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon of the back of the leg, and the thickest in the human body. It serves to attach the plantaris, gastrocnemius and soleus muscles to the calcaneus bone. These muscles, acting via the tendon, cause plantar flexion of the foot at the ankle, and flexion at the knee.
Where is the soleus muscle located?
Table of Contents. The soleus is a large muscle on the back of your lower leg. This powerful muscle arises from the back of your shin bone and attaches to your heel bone as part of the Achilles tendon. The soleus muscle is active during activities like walking, running, and jumping.

The soleus muscle and surrounding structures, from Gray's Anatomy. This is a view of the back of the right leg; most of the gastrocnemius muscle has been removed. In humans and some other mammals, the soleus is a powerful muscle in the back part of the lower leg (the calf ).
Where is the tendinous arch of the soleus located?
Part of the fibers arises from the tendinous arch of the soleus, which spans between the tibia and fibula and arches over the popliteal vessels and tibial nerve. The soleus muscle runs along the gastrocnemius muscle and together they insert onto the posterior surface of the calcaneus via the calcaneal tendon.
What is the function of the soleus?
The soleus’ function is closely related to that of the gastrocnemius muscle. Together, they constitute a chief plantar flexor - their contraction results in the plantar flexion of the upper ankle joint, enabling the lifting of the heel against gravity when walking or jumping.
Where is soleus inserted?
calcaneusThe soleus muscle, located deep/anterior to the medial and lateral gastrocnemius muscle heads, originates on the posterior aspect of the tibia (middle third of the medial border) and fibula (head and body) and inserts on the calcaneus through the Achilles tendon (see Figure 31.1).
Where does soleus attach at ankle?
The soleus is a powerful muscle that courses down the back of your lower leg and attaches to your heel bone as a part of the Achilles tendon. Injury to the soleus may result in pain and limited walking and running ability.
Does the soleus attach to the fibula?

Why does my soleus hurt after running?
So why does your calf always feel so tight? If the soleus muscle fiber is not strong enough for the job, which gets increasingly harder the more running you do, the muscle is going to fatigue and strains of the gastrocnemius muscle, causing the protective tone that you feel as a lot of stiffness and soreness.
What does it mean when your soleus hurts?
Soleus injuries are relatively common in runners. This type of injury is known as an overuse injury, which is why endurance and long-distance runners are at higher risk. Injuries commonly occur as a result of fatigue or overtraining.
What does a soleus tear feel like?
Soleus strains also tend to be less dramatic in clinical presentation and more subacute when compared to injuries of the gastrocnemius. The classic presentation is of calf tightness, stiffness, and pain that worsen over days to weeks. Walking or jogging tends to provoke symptoms [3].

How to improve soleus flexiblity?
Exercises to improve soleus flexiblity may include: The towel calf stretch (with your knee bent) The runners stretch with your knees bent. The bent knee stair hang. Keeping your knees bent during these stretching exercises ensures that the calf is kept on slack and the focus of the stretch is on your soleus.

The soleus is the plantar flexor muscle of the ankle. It is capable of exerting powerful forces onto the ankle joint.
Why is the soleus important?
The soleus is vital to everyday activities such as dancing, running, and walking. The soleus muscle helps to maintain posture by preventing the body from falling forward. The soleus is also part of the skeletal-muscle pump, which is a collection of muscles that help the heart circulate blood.

Which muscle is most effective for plantarflexion in a bent knee position?
The soleus is the most effective muscle for plantarflexion in a bent knee position (Hence called the first gear muscle). This is because the gastrocnemius originates on the femur, so bending the leg limits its effective tension.

How to palpate the soleus?
When palpating the Soleus, plantarflex the ankle with the knee flexed to 90 degrees to ensure that gastrocnemius remains relaxed. The lateral and medial aspects of the muscle can then be palpated from the lateral and medial sides of the Achilles tendon. The muscle is palpable for most of the distance from distal to proximal though the proximal attachments will become more difficult to palpate if the heads of gastrocnemius are large.
