IMO, the movements of the feet initiate the movements of the upper body via the "Kinetic Chain". Ugh what a term. How about:Movements of the feet are transmitted to the upper body via functional tension.
That means a number of things. Key item is that there is a definate intent for the upper body to move when we tip at the ankles -- and there must be! One has to realize that even though "the ankle bone's connected to the shin bone, the shin bone's connected to the thigh bone and the thigh bones connected to the hip bone" the opening of the ankle is NOT going to cause the opening of the hip. You
need to do that to organize/align your
body above the platform that you
created when you
tipped the skis.
If there is one mantra I prefer over all it's "open the hip". It's totally irrelevant if you tip first with the feet if you don't open the hip. It does more than increase range of motion, it:
1) aligns the body in a strong position over the feet
2) moves the CM forwards to enhance turn initiation
3) increases extension ( improving pressure control --flexing )
4) provides maximum turn forces to develop
5) is more efficient in use of the musculature (stacking)
Don't get me wrong, tip all you like at the ankles. Just make sure that you don't forget one reason why you are initiating by tipping -- it's to provide a target for the movement of the upper body.
Functional tension is
the "secret sauce". It's what transmits the movement from ankle to CM. Imagine your body as a whip. If the whip is stiff, you get no crack. If the whip is too supple you get no crack. If the whip has just the right tension, then you'll get a huge effect just by flicking your wrist. Well if the body is the whip, then the ankle is the wrist, and it is up to you to provide the right amount of tension so that the whip is functional.
Many examples from lemaster. Look at the path of the CM and the level of extension in this short turn. The flex here is clearly to absorb the virtual bump, else he's way past the gate when he lands....http://www.ronlemaster.com/images/la...2004-sl-1.html
It's not restricted to short turns:http://www.ronlemaster.com/images/la...004-gs-2A.html
The hunch is purely gate avoidance. Again, look at the path of the upper body and the opening of the hip.
Check out the extension on the first blue gate from the top, and how open the hip is....http://www.ronlemaster.com/images/20...oden-gs-1.html
Countless examples on lemasters site.
