Biceps Femoris

  • Origin:
    • Long Head: Distal part of the sacrotuberous ligament and posterior part of the tuberosity of the ischium.
    • Short Head: Lateral lip of the linea aspera, proximal 2/3 of the supracondylar line, and lateral intermuscular septum.
  • Insertion: The long head and short head of the biceps femoris share a common tendon that inserts on the lateral side of the head of the fibula, lateral condyle of the tibia, and deep fascia on the lateral side of the lower leg.
  • Nerve:
    • Long Head: Tibial nerve; a branch of the sciatic nerve via the sacral plexus, originating from nerve roots S1, S2, and sometimes L5 or S3
    • Short Head: Fibular nerve (peroneal nerve); a branch of the sciatic nerve via the sacral plexus, originating from nerve roots L5 – S2
  • Action:
    • Long Head:
      • Hip: Extension and some lateral rotation
      • Knee: Flexor and tibial external rotator
      • Pelvis: Posterior tilt
      • Sacrum: Counter nutation (extension) via the sacrotuberous ligament in conjunction with a posterior tilt.
    • Short Head:
      • Knee: Flexion and tibial external rotation.
      • Hip: Although the short head of

  2. Any advice in activating the glutes and external rotators while keeping the hamstrings off? Not sure if prone hip extension with knee flexed would do the trick or not?
