The gluteal muscles, often called glutes, are a group of three

hip joint.[1]

Structure

The gluteus maximus is the largest and most

. The gluteus minimus is the smallest of the three gluteal muscles and is situated immediately beneath the gluteus medius.

The bulk of the gluteal muscle mass contributes only partially to shape of the buttocks. The other major contributing factor is that of the panniculus adiposus (fatty layer) of the buttocks, which is very well developed in this area, and gives the buttock its characteristic rounded shape. Exercise in general (not only of the gluteal muscles but of the body in general) which can contribute to fat loss can lead to reduction of mass in subcutaneal fat storage locations on the body which includes the panniculus, so for leaner and more active individuals, the glutes will more predominantly contribute to the shape than someone less active with a fattier composition.[citation needed] The degree of body fat stored in various locations such as the panniculus is dictated by genetic and hormonal profiles.[citation needed]

Gluteus maximus

The gluteus maximus arises from the

, and the fascia covering the gluteus medius. The fibers are directed obliquely downward and lateralward; the muscle 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
adductor magnus. Its action is to extend and to laterally rotate the hip, and also to extend the trunk.[citation needed
]

Gluteus medius

The gluteus medius muscle originates on the outer surface of the ilium between the

anterior gluteal line below; the gluteus medius also originates from the gluteal aponeurosis that covers its outer surface. The fibers of the muscle converge into a strong flattened tendon that inserts on the lateral surface of the greater trochanter
. More specifically, the muscle's tendon inserts into an oblique ridge that runs downward and forward on the lateral surface of the greater trochanter.

Gluteus minimus

The gluteus minimus is fan-shaped, arising from the outer surface of the ilium, between the

inferior gluteal lines, and behind, from the margin of the greater sciatic notch. The fibers converge to the deep surface of a radiated aponeurosis, and this ends in a tendon which is inserted into an impression on the anterior border of the greater trochanter
, and gives an expansion to the capsule of the hip joint.

Function

The functions of muscles includes

abduction and internal as well as external rotation of the hip joint. The gluteus maximus also supports the extended knee
through the iliotibial tract.

Clinical significance

Sitting for long periods can lead to the gluteal muscles

lower back pain
, difficulty with some movements that naturally require the gluteal muscles such as rising from the seated position, and climbing stairs.

Exercise and stretching

Any exercise that works and/or stretches the buttocks is suitable, for example

Weight training exercises which are known to significantly strengthen the gluteal muscles include the squat, deadlift, leg press
, any other movements involving external hip rotation and hip extension.

Society and culture

Cultural significance

Well formed gluteal muscles have long been associated with health, strength and sexual attractiveness. In terms of health, they act as a sign of 'being in shape'. This usually means a person is also eating, sleeping and exercising properly, all of which are beneficial to health. In terms of strength, the glutes are among the largest and most powerful muscles in the body. If they are well developed then a person is more likely to be strong. They are also key contributors to movement ranges of fundamental importance, such as bending and straightening the legs, and bending, straightening and twisting at the waist. These movement ranges are key in a person's ability to move in a powerful, dynamic fashion and they are powered to a significant extent by the glutes. If they are well formed then a person is much more likely to be able to move efficiently. In terms of sexual attractiveness, the glute specialist Bret Contreras considers in physio-anthropological terms that this is based upon a sub-conscious assessment of the relationship between a physical capability to survive and prosper, and the ability to raise a family.[2]

'It stands to reason that both males and females were attracted to nice glutes, instinctively making the connection to big, strong glutes and survival, reproduction, hunting and protection.'[3]

Artistic representation

Prominent gluteal muscles are often used in art in order to imply an ability to move in a powerful, dynamic fashion; virility and fertility; and to meet aesthetic considerations in these regards.
