Gluteus Maximus - Functional Anatomy & Physiology





  • Posterior gluteal line

  • Posterior sacrum & coccyx

  • Fascia of the lumbar area

  • Sacrotuberous ligament


  • Gluteal tuberosity of the femur

  • Iliotibial tract

Major Arteries:

  • Superior gluteal artery

  • Inferior gluteal artery


Neural Innervation:

  • Inferior Gluteal Nerve (L5, S1, S2 nerve roots)


Trigger Points:




Concentric Functions:

  • Hip extension

  • Hip external rotation

  • Hip Adduction (lower portion)


Eccentric Functions:

  • Decelerates hip flexion, adduction & internal rotation during stance phase

  • Decelerates tibial internal rotation via the IlioTibial (IT) band


Isometric Function:

  • Assists in stabilizing the sacro iliac joint via the sacrotuberus ligament & the
    lateral knee via the IT band
