The gluteus maximus is the largest and strongest muscle in the body
The gluteus maximus is the largest and strongest muscle in the human body. It is located in the buttocks and is one of three gluteal muscles, alongside the gluteus medius and gluteus minimus. The gluteus maximus is the outermost muscle of the buttocks and is enveloped in a thin fascia that separates it from the adjacent subcutaneous tissue.
The gluteus maximus is responsible for several functions, including the movement of the hip and thigh. It is the chief anti-gravity muscle during sitting, counteracting and controlling the flexion of the hip. It also assists in rising from a seated position, climbing stairs, and staying in an erect position. The muscle supports the pelvis, which is the seat of the axial skeleton, and helps to stabilise the hip joints.
The gluteus maximus is involved in various sports, such as running and weightlifting. It is particularly active during forceful movements such as standing up, running, and climbing. Exercises such as squats, lunges, and split squats can be used to target and strengthen the gluteus maximus.
The muscle is vascularised by the muscular branches of the inferior and superior gluteal arteries and receives innervation from the inferior gluteal nerve. During reconstructive surgery, the gluteus maximus may be exposed and retracted to gain access to the hip and sacroiliac joints.

It is located in the buttocks and is the outermost muscle
The gluteus maximus is located in the buttocks and is the outermost muscle. It is the biggest and strongest muscle in the human body. It is enveloped in a thin fascia that separates it from the adjacent subcutaneous tissue. The gluteus maximus is the most superficial gluteal muscle that forms the prominence of the gluteal region. It is the chief antigravity muscle during sitting, counteracting and controlling the flexion of the hip. It is responsible for the movement of the hip and thigh.
The gluteus maximus is connected to the coccyx, or tailbone, as well as other surrounding bones. It starts from several points on the pelvis and wraps around the backside, attaching to the femur (thigh bone). The muscle covers the gluteus medius, pelvic bones, and the proximal attachments of the hamstring muscles. It also covers the deep lateral hip rotators and the start of the hamstrings. The gluteus maximus is involved in several sports, from running to weightlifting.
The muscle's main functions are the extension and external rotation of the thigh at the hip joint. When the leg is flexed at the hip, the gluteus maximus extends it to bring the leg into a straight line with the body. The muscle also acts as an adductor and external rotator of the limb. Its upper fibres act as abductors of the hip joints. The gluteus maximus is passive except during certain forceful movements, such as standing up, running, and climbing.
The gluteus maximus is vascularized by the muscular branches of the inferior gluteal and superior gluteal arteries, the branches of the internal iliac artery. The inferior gluteal nerve innervates the muscle. The gluteus maximus is important for relieving the pressure of the weight of the trunk on the ischial tuberosities when sitting down. It also supports the pelvis and trunk upon the head of the femur, particularly when standing on one leg.

The muscle is involved in several sports, from running to weightlifting
The gluteus maximus is the largest and most powerful muscle in the human body. It is the outermost muscle of the buttocks, and it plays a key role in movement and posture. Its primary function is hip extension, but it also plays a role in external rotation and abduction of the hip. These movements are essential for lateral stability and balance, allowing for smooth changes in direction and agility.
The gluteus maximus is involved in several sports, from running to weightlifting. It is crucial for athletes to prevent injury and enhance performance. For example, during activities that require side-stepping or pivoting, the muscle helps stabilize the pelvis and maintain alignment. This function is essential for athletes in dynamic sports that demand quick directional shifts, such as sprint running and jumping.
The gluteus maximus also serves as a powerhouse in human locomotion. It contains a blend of Type I and Type II muscle fibres, allowing it to adapt to a wide range of physical demands. Type I fibres are slow-twitch fibres that are crucial for sustained, low-intensity activities as they are resistant to fatigue. Type II fibres, or fast-twitch fibres, are more common in athletes and are tailored to their specific sports requirements.
Specific exercises that target the gluteus maximus include squats, lunges, single-leg squats, deadlifts, and various non-weight bearing exercises. These exercises can help strengthen the muscle and improve athletic performance. Additionally, understanding the anatomy and function of the gluteus maximus is essential for those interested in fitness, rehabilitation, or simply learning about human body movement.

The gluteus maximus supports the pelvis and the trunk
The gluteus maximus is the outermost muscle of the buttocks, arising from connections to nearby structures. It is the biggest and strongest muscle in the human body. It is enveloped with a thin fascia that separates it from the adjacent subcutaneous tissue. It is connected to the coccyx, or tailbone, as well as other surrounding bones. The gluteus maximus muscle is responsible for the movement of the hip and thigh.
The gluteus maximus is passive except during certain forceful movements, like standing up, running, and climbing. If you sit on it a lot and don't activate it much, it becomes weaker and slower to activate. The gluteus maximus is involved in several sports, from running to weightlifting. A number of exercises focus on the gluteus maximus and other muscles of the upper leg, such as squats and lunges.
The gluteus maximus is also important during reconstructive surgery. It is often retracted during hip surgery, and its exposure is the first step in certain approaches to the sacroiliac joint and the acetabulum.

It is vascularized by the muscular branches of the inferior and superior gluteal arteries
The gluteus maximus is the outermost muscle of the buttocks. It is the largest and most superficial of the three gluteal muscles. It extends from the pelvis to the gluteal tuberosity of the femur. The muscle's main functions are the extension and external rotation of the thigh at the hip joint. It also supports the pelvis and trunk upon the head of the femur, which is particularly important when standing on one leg.
The gluteus maximus is vascularized by the muscular branches of the inferior and superior gluteal arteries. The inferior gluteal artery is a terminal branch of the internal iliac artery, supplying the gluteal and thigh regions. It gives off several muscular branches that supply the muscles of the pelvic diaphragm. In the gluteal region, the artery gives off muscular branches that supply the gluteus maximus, obturator internus, superior gemellus, inferior gemellus, and quadratus femoris muscles. The inferior gluteal artery proceeds to descend along the greater trochanter of the femur, supplying the skin and dividing into its terminal branches.
The superior gluteal artery is the largest and final branch of the internal iliac artery. It passes between the lumbosacral trunk and the first sacral nerve and exits the pelvis through the greater sciatic foramen. The superior gluteal artery supplies the gluteus maximus and overlying skin, gluteus medius, gluteus minimus, and tensor fasciae latae. It gives off two terminal branches: the superficial and deep branches. The superficial branch gives off several branches that contribute to the blood supply of the gluteus maximus by forming anastomoses with the branches of the inferior gluteal artery. These anastomoses provide about one-third of the blood supply to the gluteus maximus.
The gluteus maximus is at risk of injury during surgery due to its vascular supply. An incision near the posterior aspect of the greater trochanter is required to expose the muscle. The muscle is then completely incised to access the posterior aspect of the joint capsule. This procedure will inevitably cause bleeding of the vessels, so it is expected. Incising the vessels can be advantageous as the surgeon can cut and coagulate them before avulsion during retraction.
