Muscles used during running

Ever though how many muscles are used when you are running????


Well including the leg muscles, which take the main pressure, the back muscle and the stomach muscles also get effected. These come in play to support your spinal cord while you are running. At times, people complain that they have pain at the lower back when they run fast or for a longer distance. This is due to the fact that your upper abdominal work hard to support the spinal cord while you were running.


The stomach muscles hold the whole of the upper abdominal area ensure that the spinal chord is not slipped.


Coming back to the main muscles, that is leg muscles; there are many leg muscles which are supporting us when we are running. These can be classified as Primary muscles.



The quadriceps femoris (quadriceps) --> is actually a muscle group that comprises several ones on the front of a thigh
The hamstring --> comprises four on the back of the left or right thigh and they move the knee joint
The gluteus maximus --> is one of the three gluteal muscles, is the most superficial and largest among them, and is the primary contributor to the shape of the buttocks. The primary purpose of the gluteus maximus is to maintain the trunk of the body in the erect posture — that is, to extend the hip. This explains why other primates, which ambulate on all fours, tend to have much flatter buttocks than the buttocks of humans
The iliopsoas --> with the psoas major doing the majority of the work — supports hip flexion
The calf muscle --> is to plantar flex the ankle and to flex the knee

The biceps brachii --> is a muscle on the upper arm whose purpose is to rotate the forearm and to flex the elbow. Because running is more efficient when the elbow is bent, the biceps brachii supports running
The upper abdominals --> comprises the muscles in the upper half of the abdomen
The lower abdominals --> comprises those in the lower half of the abdomen.

Together, the upper and lower abdominals support the core strength that runners need for maintaining good posture, which is crucial for maximizing performance and avoiding injury. Because running can cause a lot of rotation of the spine, it is important to have strong upper and lower abdominals to stabilize the spine and to minimize the dissipation of energy during the transfer of power to the extremities

Running on a regular basis has many benefits, including weight loss, stress relief and maintaining a strong and healthy body.
