The soleus muscle is a powerful muscle in the back of the lower leg (the calf). It is a broad, large, and flat muscle located underneath the gastrocnemius, and it gets its name from the Latin word solea, meaning sandal. The soleus muscle is involved in various functions, including flexing the ankle to point the toes, walking, running, and jumping. Additionally, it plays a vital role in pumping blood from the lower leg back to the heart, acting as a skeletal muscle pump. The soleus is also important for maintaining standing posture and preventing forward falls. Injuries to the soleus muscle are common, especially among athletes, and can result in pain and limited mobility.

What You'll Learn
The soleus muscle is a powerful muscle in the calf
The soleus muscle is involved in plantar flexion, which is the action of pointing the toes downward. This movement is particularly important in walking, running, and jumping. The soleus is the most effective muscle for plantar flexion in a bent knee position, as the gastrocnemius originates on the femur, so bending the leg limits its effective tension. The soleus is also responsible for stabilising the leg during stance when running, making it key for injury prevention in runners.
The soleus muscle also has an important role in maintaining standing posture. Its constant pull stops the body from falling forward. Additionally, the soleus acts as a muscular pump, helping to pump venous blood back to the heart from the periphery. This is often referred to as the skeletal muscle pump.
The soleus is a complex, multi-pennate muscle in humans, with a separate (posterior) aponeurosis from the gastrocnemius muscle. It is composed of two muscle bellies, medial and lateral, which are separated by a midline septum. The soleus is prone to injury, particularly in athletes who run and jump, as this involves constant stretching and contraction of the muscle. Treatment for a soleus tear involves rest, ice, compression, and elevation, along with physical therapy.

It is involved in walking, running, and jumping
The soleus muscle is a powerful muscle in the calf that is involved in walking, running, and jumping. It is a large, broad, and flat muscle located in the back part of the lower leg, just underneath the gastrocnemius muscle. Together, these two muscles form the Achilles tendon, which attaches at the heel.
The soleus muscle is responsible for flexing the ankle to point the toes and is essential for maintaining balance during walking and running. When the soleus contracts, it lifts the heel towards the back of the knee, resulting in plantar flexion, which points the toes downward. This action increases the angle between the foot and the shin, helping to propel the body forward during walking and running.
The soleus muscle is also important for injury prevention in runners. Including this muscle in strength training helps to stabilize the stance and improve running performance. Additionally, the soleus muscle functions as a muscular pump, assisting in returning venous blood from the lower leg back to the heart. This secondary function is often referred to as the skeletal muscle pump.
Injuries to the soleus muscle can result in pain and limited walking and running ability. Tears in the soleus muscle can occur due to sudden, forceful movements or overuse and are common in athletes who run, jump, or perform quick pivoting movements, such as runners, gymnasts, and field athletes. Treatment for a soleus tear typically involves rest, ice, compression, elevation, and physical therapy, with severe cases requiring surgery.

It is also responsible for pumping blood from the lower leg back to the heart
The soleus muscle is a powerful muscle in the calf, running from just below the knee to the heel. It is one of the main muscles that make up the calf complex, along with the gastrocnemius muscle. These muscles are stacked on top of one another and work together to perform plantar flexion, or pointing the toes downward. The soleus is also responsible for pumping blood from the lower leg back to the heart.
The soleus muscle is a large, broad, and flat muscle located in the posterior leg, underneath the gastrocnemius. It is a skeletal-muscle pump that assists in returning venous blood back to the heart for recirculation. When the soleus muscle contracts, it acts like a sponge, pushing blood through the veins in the leg. These veins contain small "one-way" valves that prevent blood from pooling back down into the lower leg. This action of the soleus muscle as a spongy pump is often referred to as the skeletal muscle pump.
The soleus muscle is particularly important for athletes, especially runners and jumpers, as it is responsible for a powerful push-off and stabilizing the leg during stance when running. It is also involved in standing and walking, and helps to maintain standing posture by providing a constant pull that prevents the body from falling forward.
Injuries to the soleus muscle can result in pain and limited walking and running ability. Common signs of a tear include sharp pain in the calf, swelling, bruising, weakness, and trouble walking or standing on tiptoe. Treatment for a soleus tear typically involves rest, ice, compression, and elevation, along with physical therapy. In some cases, surgery may be required.
The soleus muscle is a vital part of the lower leg anatomy, providing stability and contributing to overall balance and posture. Its function as a muscular pump also plays a crucial role in maintaining healthy blood circulation.

The soleus is harder to damage than the gastrocnemius muscle
The soleus muscle is a powerful muscle in the calf that is involved in standing, walking, running, and jumping. It is closely connected to the gastrocnemius muscle, with some anatomists considering them a single muscle, the triceps surae. The gastrocnemius is the most commonly injured and strained muscle of the calf due to its proximity to the skin's surface and its connection to two joints: the knee and the ankle. This makes it more susceptible to overextension and tears.
In contrast, the soleus is harder to damage than the gastrocnemius due to its deeper location and different anatomy. It crosses over fewer joints, which lowers the risk of overextension and tears. The soleus is a broad, large muscle located in the posterior leg, inferior and deep to the gastrocnemius. It is narrower than the gastrocnemius and has a less robust vascular supply.
The soleus muscle is responsible for flexing the ankle to point the toes and is utilized in walking, running, and jumping. It is also involved in pumping blood from the lower leg back to the heart. This function is often referred to as the skeletal muscle pump or soleal pump. The soleus muscle contracts and acts like a sponge, pushing blood through the veins back to the heart.
Injuries to the soleus muscle can occur due to sudden, forceful movements or overuse and are more common in runners, triathletes, gymnasts, and track and field athletes. Signs of a tear include sharp pain in the calf, swelling, bruising, weakness, and trouble walking or standing on tiptoes. Treatment for a soleus tear involves rest, ice, compression, elevation, and physical therapy. In some cases, surgery may be required, and recovery can take several weeks to months.

It is one of the main muscles that make up the calf complex
The soleus muscle is indeed one of the primary muscles that make up the calf complex. The calf complex is composed of several different muscles, with the two main ones being the gastrocnemius and the soleus. These muscles are stacked on top of one another, with the gastrocnemius being the most superficial and the large, broad, and flat soleus muscle located just underneath. The gastrocnemius crosses the back of the knee joint, while the soleus does not.
The soleus muscle is a powerful muscle in the back part of the lower leg (the calf) that runs from just below the knee to the heel. It is involved in standing and walking and is responsible for flexing the ankle to point the toes. This muscle is closely connected to the gastrocnemius muscle, and some anatomists consider this combination to be a single muscle, the triceps surae. The soleus is also involved in running and jumping, and its name is derived from the Latin word "solea," meaning "sandal."
The soleus muscle is a large muscle, though it remains relatively thin and flat along its length. It has a wide attachment surface at the back of the knee, spanning across two bones. The soleus consists of two muscle bellies, medial and lateral, which are separated by a midline septum distally. The medial belly originates from the middle third of the medial border of the tibia, while the lateral belly originates from the posterior surface of the head and body of the fibula. Both bellies insert into the calcaneus (heel bone) through the Achilles tendon, distal to the insertion of the gastrocnemius.
The soleus muscle plays a crucial role in plantar flexion, which is the action of pointing the toes downward. This movement increases the angle between the foot and the leg, and it is essential for maintaining balance and posture while standing and walking. The soleus is particularly effective in plantar flexion when the knee is bent, as the gastrocnemius muscle's origin in the femur limits its effective tension when the leg is bent. The soleus muscle's slow-twitch fibres also help resist fatigue during regular movement, making it the primary muscle for plantar flexion when walking.
