Sudden down push at apex - valid technique or not - Page 7

If a skier is in a turn, and moves his COM towards the center of the turn, his/her speed will increase. This is caused by the fact that the Kinetic Energy of Rotation does not change, but the radius that the COM is describing decreases. (I think someone else also suggested reading this).

So it is not necessary for the ski to bend more to pick up speed - thought it may also help. All that is required is that the skier move his/her COM toward to center of the turn, and speed will increase!!!. Conversely, if the COM moves out, the speed will go down.
Just finished catching up the thread. I think this is a good proof. Thanks for digging out the theory.

Ok, I was just wondering since Beni has been on Atomic for quite some time. I know that one boot designer from Nordica whent to Head. Originally Bode, same as Kalle, was on Nordica so I would not be surpriced if Bode had something to do with it in some twisted way. Maybe you have some more to tell?

I read a little story today that is appropriate for most of these technical discussions....

Two monks were crossing a bridge. One asked the other, "What is Zen?". The second monk picked up the first and threw him in the river, telling him to swim in it, become one with it, but not ask about it because words don't mean shit.

Great stuff

Oh I will pass that on to our team.

He has been testing various cuffs (Salomon upper on Atomic lower, even a laminated leather cuff) and boot sole rotations and grinds to minimize this issue.

And to clarify, I'm not arguing for an extremely extended leg, I'm just arguing against the concept proposed in the first post of this thread.

In general I think we are talking about a similar thing, but the OP is not .

You cant win the WC and the Olympics if you are canted the wrong way.

He has the same problems as everybody else. He is onesided . And he does what everybody else does. He doctors his boots.

Thanks for the beating jdistefa....

I said I would look at this video frame by frame to look for the pumping, and I never got around to it. I will try to later.
