Introduction
Hello everyone! Today, let’s talk about the psoas major and iliacus muscles, which are centrally located in the body and play crucial roles in posture and
movement. These muscles are collectively known as the iliopsoas and extend from the lumbar spine to the femur. Let’s dive into the details of these important
muscles that are essential for everyday activities and sports.
What is the Psoas Major?
The psoas major is a long muscle that originates from the lumbar spine and attaches to the lesser trochanter of the femur. This muscle primarily functions
to flex the hip joint, making it essential for actions like lifting the leg, walking, and running. Additionally, the psoas major stabilizes the lumbar
spine, which is crucial for maintaining proper posture.
Main Functions of the Psoas Major:
? ? Hip flexion
? ? Lumbar spine stabilization
? ? Assisting in anterior pelvic tilt
What is the Iliacus?
The iliacus muscle originates from the iliac fossa (the inner surface of the pelvis) and merges with the psoas major to attach to the lesser trochanter
of the femur. Like the psoas major, the iliacus is involved in hip flexion, contributing to movements like lifting the leg and walking. The iliacus also
plays a role in stabilizing the pelvis.
Main Functions of the Iliacus:
? ? Hip flexion
? ? Pelvis stabilization
Importance of the Iliopsoas
The iliopsoas is extremely important in daily activities and sports. For instance, actions like climbing stairs, running, and jumping all rely on the iliopsoas.
In modern society, where many people spend long hours sitting at desks, the flexibility of the iliopsoas can decrease, leading to back pain and poor posture.
Stretching and Strengthening the Iliopsoas
To maintain the health of the iliopsoas, regular stretching and strengthening exercises are essential. Here are some simple stretches and exercises:
Stretching Method:
- 1. Sit on the floor with one knee bent and the other leg extended backward.
- 2. Bend the knee of the forward leg at a 90-degree angle and stretch the hip joint of the backward leg.
- 3. Lean forward to thoroughly stretch the iliopsoas. Perform this alternately on both sides.
Strengthening Exercise:
- 1. Lie on your back and draw one knee towards your chest.
- 2. Extend the opposite leg straight and lift it slightly off the floor.
- 3. Alternate the legs while focusing on engaging the iliopsoas during the movement.
Conclusion
The psoas major and iliacus muscles play vital roles in our movements and posture. Understanding and properly caring for these muscles can help maintain
a healthy body and correct posture. Incorporate iliopsoas stretches and exercises into your daily routine and training to strengthen the central part of
your body.
