The gluteus maximus muscle originates from several sites; the posterolateral aspect of the sacrum and coccyx, the sacrotuberous ligament, gluteal surface of ilium (behind the posterior gluteal line), thoracolumbar fascia and gluteal aponeurosis. The muscle fibers take an inferolateral course, converging towards the femur.
Why is the gluteus maximus not active?
Unlike the other gluteal muscles, the gluteus maximus is not active while standing; instead, it intermittently activates while walking or climbing. While sitting down, the static contraction of gluteus maximus is important for relieving the pressure of the weight of the trunk on the ischial tuberosities.
What muscles help with pelvic stability?
On the contrary, when its distal attachment is fixed, gluteus maximus pulls the pelvis posteriorly. As it usually happens in synergy with the same action of the hamstring muscles, this action of gluteus maximus helps to bring the trunk from a flexed to an upright position. Furthermore, these muscles help in maintaining the upright posture by balancing the pelvis on femoral heads.
