Factor restricting hip extension

Fairly basic question i know. But are there any factors, other than the ones listed below, that will prevent full hip extension?

  • Lack of strength
  • Lack of hip mobility- internal rotation, any others?
  • Pelvic position (anterior tilt) cutting off glute involvement

Any others?


Tightness in adductor longus

Tightness in any muscles that perform hip flexion will limit hip extension.

Lacking a complete/full arm-swing.

The number one suspect- struggling/fighting for speed instead of relaxing

Also look at the general position of the pelvis. if everything looks okay in terms of the hip flexors, take a look bilaterally at the postion of the ilium. if stuck posteriorly, may also inhibit hip extension
