introduction

The gluteus maximus takes its 16 cm long and 4 cm wide origin from the back surface of the ilium and acts in alternation with the iliopsoas muscle when walking upright. While the iliopsoas contracts when the hip joint is flexed, the gluteus maximus muscle is stressed during the stretching movement.

Approach, origin, innervation

Approach:

Roughness of the lateral lip of the femur (Tuberoitas glutaea femoris)

Origin:

• Iliac blade posterior surface (Thoracolumbar fascia)
• Dorsal surface of the sacrum and ischial tuberosity (Sacrotuberous ligament)

Innervation: N. gluteus inf.

How is the muscle trained / contracted?

Due to its multitude of functions, the gluteus maximus can be contracted through numerous forms of exercise. The most common exercises include:

• Leg press
• Squats
• Abductor machine
• Hip trainer

How is the gluteus maximus muscle stretched?

In order to specifically stretch the gluteus maximus muscle, the athlete stands on one leg and tries to pull the thigh to the stomach. The knees are covered by the hands.

function

The function of the gluteus muscle is to forcefully stretch the hip joint. This takes place when straightening up from a crouch, when walking, etc. By attaching to the thigh bandage, he is also able to stretch the lower leg in the knee joint. When the upper body is bent forward, the large gluteal muscle prevents falling through strong contraction. In addition, it partially takes on the function of adduction and external rotation in the hip joint.
