[QB]DavidM, I was only talking about physical distance that his body moves relating to the assumptions fox made that we only move very little in relation to our feet.
Your court case is a good question. I think Bode is allowing his feet to go way outside and using the force that pulls his body down the hill. So I don't think he "jumped". I see no platform from where he could have "jumped" from plus I see a lot of momentum to his skis shooting out to his left and the outside of the new turn.
Fastman: Tog, I empathize with your confusion on Fox's statement that the CM doesn't move much in relation to the skis. In the Bode shot sequence his hip is clearly well inside the vertical plane of the feet when he's at the apex of the turn. As I am sure, Fox, that you see that, I can only assume that you are refering to something else. Rather than the feet in relation to the vertical plane, are you refering to the feet in relation to the line of centrifugal force directed through the hip? That would put them more in line. As far as striving for a quiet upper body, I'm right with ya kid, just don't post to many pictures of Bode because he's doing his damndest to prove that goal as unimportant!
Tog, there is a platform to jump. In the completion phase of a turn the skier is, hopefully, in a state of dynamic balance on his uphill edges resisting the combined forces of centrifugal force and gravity. Those engaged edges can also be used a stable base of resistance to pull against. In other words you can use your leg muscles to pull your body up and over the skis. Just as the edge resists your pushing on it during the turn, it can resist your pulling on it during the turn transition phase. David's question (I think) is do we do that, or do we just relax our resistance and allow gravity to do the work for us. Good question. I would suggest that we utilize a variety of a combinations of the two. In relaxed free skiing just a very subtle pull to initiate the gravitational fall is needed. In situations where the glide phase between turns must be eliminated and a new turn must be started quickly, a strong pull to expediate the transition can be used. I would think race turns such as the one in the Bode shot sequence would often require a quick strong pull transition. Comments appreciated.
