I have always had problems with internal rotation of the hips. Very common I know, but in my case is most likely pointing towards retroverted hips (left more than right), given the big difference between my external and internal rotation range and a positive Craig's test that measures retroversion (and anteversion) of the hip. My hips simply seek a more externally rotated (foot turn out) position to keep the hip joint centred.
Many gymnastic positions call for feet, ankles and knees together (pikes, narrow hurdle, kneeling, squats etc) and even vertical shin/lunge positions are ideally done in neutral hip positions with respect to IR/ER. Yet vertical shin feel better when the back leg is allowed to externally rotate to keep the retroverted joint aligned. In fact not allowing some ER of the back leg makes the pelvis internally rotate (in the transverse plane) to keep the joint congruent.
So my question is, what is the gymnastic bodies' advice on whether in this case one should adjust the ideal position and allow some ER of the hips in pikes/lunges/kneeling/squats etc?
Also is it advisable not to chase the ideal mobility on say swivel hips, as the joint will never allow full range of motion in internal rotation?
