The Psoas is a muscle with many anatomical and functional peculiarities that are often unknown and not considered when assessing why athletes get injured or how they should be treated. The Psoas muscle consists of two distinct muscle bellies, which is why in the classic anatomical nomenclature it is called the Psoas Iliacus. It has one belly that is inserted into the deep face of the lumbar spine and another belly that is inserted into the inside of the iliac blade of the pelvis; these two bellies form the Psoas Iliacus muscle, both have two tendons that progressively join together to finally insert into a point on the femur called the lesser trochanter. Once we know its anatomy, we must understand its function. The Psoas is a muscle that jumps over the hip joint and flexes it. Simply by walking we are already using this muscle, since it is the muscle that launches the thigh when taking a step. In athletes, this muscle is stressed when they kick hard and can be injured when we leave it behind in a stride. A little-considered function of this muscle is that it is in charge of keeping the body in an upright position and prevents our body from falling backwards. It is easy to understand the function of its antagonist, the gluteus, which is in charge of keeping our trunk from falling forward and erect. The Psoas, for its part, keeps the body in a vertical position, preventing us from falling backwards. A movement such as the hyperextension that athletes such as tennis players do backwards with the movement of the serve can cause an injury. The Psoas is one of the organs that has been most damaged when humans went from being on all fours to standing upright and bipedal. In this process, the Psoas stopped working in a linear way like all muscles do. When humans stood up, the Psoas was forced to make an angle, leaning on a bone that is a branch of the pubis. This makes the muscle always work supported, with pressure and even with friction or rubbing on the pubic bone. At iQtra we find many Psoas injuries that can be both in the muscle belly and in the tendon. The transition of fibers between muscle and tendon occurs just when it rests on the pubic branch, at that point of stress and friction is when almost all injuries occur. The symptoms can be, groin pain when you move your leg forward while walking, or when you have to raise your leg to put it in the car, there the Psoas is pulled to lift the thigh and it causes pain to the patient, we also find it in gestures such as leaving the leg behind In the following video we can see how to exercise the Psoas muscle and not injure it #Psoas #Injuries #iqtra #angelvillamor #psoasmuscle
