What is the function of the gluteus maximus muscle?

Rick Olderman

Physical Therapy

The gluteus maximus is an important muscle because it is a prime mover of the leg bone into extension (moving the leg backwards) or propelling the body forward as when walking or running. It also helps externally rotate (rotating the leg outward) as previously mentioned. It has another function, though, that's just as important, which is to keep the head of the femur from sliding forward (anterior femoral glide) in the hip socket.

Functions of Muscles

Muscles keep your body moving by contracting and relaxing. In some cases, this movement is voluntary. You use your skeletal muscles to bend your arms or legs when you want. Smooth muscles, however, are part of the involuntary movement within your body. These muscles surround organs of the digestive tract as well as the arteries. You don't have to be aware of the process -- your brain controls the function! One of the most vital muscles is the cardiac muscle, or heart. Understanding the functions of muscles can help you keep them healthy or treat injury as needed.
