The gluteus maximus (also known collectively with the gluteus medius and minimus, as the gluteal muscles, and sometimes referred to informally as the 'glutes') is the largest and most superficial of the three gluteal muscles. It makes up a large portion of the shape and appearance of the hips.

It is a narrow and thick fleshy mass of a quadrilateral shape, and forms the prominence of the nates.

Its large size is one of the most characteristic features of the muscular system in humans,^[1] connected as it is with the power of maintaining the trunk in the erect posture. Other primates have much flatter hips.

The muscle is remarkably coarse in structure, being made up of fascicles lying parallel with one another, and collected together into large bundles separated by fibrous septa.

Structure

Muscles of the gluteal and posterior femoral regions, showing origin and insertion of gluteus maximus muscle.

It arises from the posterior gluteal line of the inner upper ilium, and the rough portion of bone including the crest, immediately above and behind it; from the posterior surface of the lower part of the sacrum and the side of the coccyx; from the aponeurosis of the erector spinae (lumbodorsal fascia), the sacrotuberous ligament, and the fascia covering the gluteus medius (gluteal aponeurosis). The fibers are directed obliquely downward and lateralward; The gluteus maximus has two insertions:

those forming the upper and larger portion of the muscle, together with the superficial fibers of the lower portion, end in a thick tendinous lamina, which passes across the greater trochanter, and inserts into the iliotibial band of the fascia lata;

the deeper fibers of the lower portion of the muscle are inserted into the gluteal tuberosity between the vastus lateralis and adductor magnus.

Bursae

Three bursae are usually found in relation with the deep surface of this muscle:

One of these, of large size, separates it from the greater trochanter;
a second, (often missing), is situated on the tuberosity of the ischium;
a third is found between the tendon of the muscle and that of the vastus lateralis.

It is also inserted on the lateral condyle of the femur.

Function

When the gluteus maximus takes its fixed point from the pelvis, it extends the acetabulofemoral joint and brings the bent thigh into a line with the body.

Taking its fixed point from below, it acts upon the pelvis, supporting it and the trunk upon the head of the femur; this is especially obvious in standing on one leg.

Its most powerful action is to cause the body to regain the erect position after stooping, by drawing the pelvis backward, being assisted in this action by the biceps femoris (long head), semitendinosus, semimembranosus, and adductor magnus.

The gluteus maximus is a tensor of the fascia lata, and by its connection with the iliotibial band steadies the femur on the articular surfaces of the tibia during standing, when the extensor muscles are relaxed.

The lower part of the muscle also acts as an adductor and external rotator of the limb. The upper fibers act as abductors of the hip joints.

Society and culture

Training

The gluteus maximus is involved in a number of sports, from running to weight-lifting. A number of exercises focus on the gluteus maximus as well as other muscles of the upper leg.

Hip thrusts
Quadruped hip extensions
Kettlebell swings
Squats (if taken below parallel) and variations like split squats, pistol squats and wide-stance lunges
Deadlift (and variations)
Reverse hyperextension
Four-way hip extensions
Glute-ham raise

Injury analysis

Functional assessment can be useful in assessing injuries to the gluteus maximus and surrounding muscles. These tests include:

30 Second Chair to Stand test

This test measures a participants ability to stand up from a seated position as many times as possible in a thirty-second period of time.^[2] Testing the number of times a person can stand up in a thirty-second period helps assess strength, flexibility, pain, and endurance,^[2] which can help determine how far along a person is in rehabilitation, or how much work is still to be done.

Passive piriformis stretch.

The piriformis test measures flexibility of the gluteus maximus. This requires a trained professional and is based on the angle of external and internal rotation in relation to normal range of motion without injury or impingement.^[3]

Contraction-evoked vasodilation and functional hyperemia are compromised in branching skeletal muscle arterioles of young pre-diabetic mice.

We hypothesized that pre-diabetes compromises contraction-evoked vasodilation of branching second-order(2A), third-order(3A), and fourth-order(4A) arterioles, where distal arterioles would be affected the greatest.

Effect of trunk motor control training on hip muscles in elite football players.

Mendis D1, Stanton W, Hides J.Author information 1Australian Catholic University, Brisbane, Australia.AbstractBACKGROUND: Decreased size and altered function of lumbo-pelvic muscles has been found in elite athletes with low back pain (LBP). Previous research has shown that training trunk neuromotor control in elite football players with and without LBP improved the size and function of muscles important in stability of the lumbo-pelvic region. Hip muscles also contribute to lumbo-pelvic stability and imbalances in these muscles have been associated with LBP in collegiate athletes.
