Well I finally have a few moments to write something here. Let's start with purpose and deliberateness. While Vonn is not skiing gates, there is a certain purpose being expressed in her skiing. Haste. She also is demonstrating patience. So while these two may seem at opposite ends of the spectrum, she clearly shows otherwise. Looks like Strawpile, a run I know quite well.
So review her body movements again but this time break them down into quadrants. inside upper / lower, outside upper / lower. Include the hands and arms in this as well. For the moment leave out the head since like a falcon it is pretty steady. A subject I will return to in due time but for now let's concentrate on the four quadrants.
1. Outside lower: variable edge angles and weight bearing, adduction of the leg that results in the knee being driven medially. Flexing and extending as needed to allow the core to move along it's path while the feet move along theirs. During the strong pressure phase this slows down (relative to the rest of the body) because the core and the feet are traveling along nearly parallel paths. At least momentarily.
2. outside upper half: crosses over the skis during the first third of the turn, counter balances to keep pressure focused on the inside edge of the outside ski. Migrates towards the new turn beginning at the apex of the current turn. Along with the lower outside half acts like an anchor for the rest of the body. More on this later...
3. inside upper half: much the same as the outside upper half but the arm in particular does something different than the outside shoulder and arm. Proceeds the upper and lower half into the new turn.
4. inside lower half: hyper active since it's role is to define the turn. Flexing to drop the hips inside the turn, knee rotating externally to steer the entire system, hip staying forward to mitigate the natural aft stance caused by the leg and hip flexing. Foot and ankle flexing in both directions (Dorsi / plantar) to absorb the small irregularities.
