You're midway through a turn, in perfect balance, you balance point is located right under the big toe side of your outside foot. Someone casts a hogwarts spell, and your 12 meter radius skis magically turn into 27 meter GS skis. What will this do to your state of balance? How will it effect your point of balance? If you do nothing to adjust for the changes, what will the outcome be? What will you do to adjust?
Rick, to suggest that people on this thread does not understand this kindergarten level physics is a bit insulting.
Regarding OLR vs ILE I don't really see the point. In the beginner corral you can certainly make a pure ILE or OLR, but in a performance turn with great forces it is simply not possible.
In their pure forms both methods would transfer the turn force to the inside foot and it is simply not possible if they are in the order of 3-4 G's, or even 2 Gs for a "normal" skiier.
Most transition in this case involve some level of vaulting primarily over the outside leg. In a retraction you need to have done some vaulting before you rip you knees up, otherwise you will simply land on your butt. The CoM must already be on its way up.
In racing a fast transition is often important and you can make it faster by pushing on the inside leg but I don't see why you would call that inside leg extension. You are not strong enough to extend the inside leg. The reason it is extending is because you are vaulting over the outside leg, thus making the distance between the inside ski and hip joint longer. When you have gotten the vaulting started there is no reason to keep pushing on the inside leg, unless you want a really high position in transition. Its a bit funny, in the very turn that Ligety describes this the outside ski is still firmly engaged in the snow when the inside ski is in the air. The major extension comes after edge neutral.
This is a picture showing muscle activity in a tall transition, made by a former world champion. If you know your anatomy the muscle acronyms should be clear.
The left part is for the outside leg and the right part the inside.
Rectus femoris in the inside leg is not activated to a higher level before vastus lateralis and vastus medialis is relaxed in the outside leg as far as I can see.
