What are your glutes?
A group of 3 muscles that serve an important role in controlling hip movement and core and pelvic stability.
1. Gluteus Maximus: The largest of the three muscles and the largest muscle in the hip, accounting for 16% of the total cross sectional area. Glute Maximus is the primary hip extensor as well as assisting with proper upright posture.
How? Gluteus Maximus originates in the fascia of the erector spine, along the sacrum, coccyx and through these into the thoracolumbar fascia. Through this attachment, it couples with the ipsilateral multifidus and contralateral latissimus dorsi forming posterior oblique and deep longitudinal myofascial slings.
Gluteus maximus and the hamstrings also work together to extend the trunk from a flexed position by pulling the pelvis backwards, such as standing up from a bent forward position. Eccentric control is also provided when bending forward.
2. Gluteus Medius: Primary muscle that controls hip abduction and is essential to maintaining a level pelvis during walking, running and single leg activities. Such as: kicking a soccer ball.
3. Gluteus Minimus: The smaller of the three; similar to gluteus medius and assists in stabilization of the pelvis while walking.
The gluteus medius/gluteus minimus muscle group plays an important role in the core stability and pelvic stability. These muscles have 3 distinct sets of fibers: Anterior, Middle and Posterior. They serve in a role not only of hip abduction at the hip, but also aid in hip extension and external rotation. The anterior fibers contribute to hip internal rotation. In our gait, these muscles properly position and stabilize the pelvis as we move into stance phase, allowing us to have stability in single limb stance. In order to effectively produce this stability, these muscles must routinely produce a force of at least 2 times that of a person’s body weight.
