Suggested by Rick in annother thread we should try a discussion of how to ski with focus on our core. Efficient CoM managing. Putting our hips in the right place. Let me quote Rick:
Here is what inspired Rick:
Excellent words Pierre thank you, but lets not look at Herman Maier this time. Lets take a look at Tanja Poutiainen and her CoM management and get a discussion going with ref to this excellent photo sequenze right here:
The feet and legs exploit the forces, that move the core, that tip the feet, that turn the skis that Jack built.
Here is what I see in the HM montage.
I see a superb athlete who's center of mass flow is right on the fastest line and masterfully controlled. I see his center of mass as the control center for what is going on. I see two active feet connect and coordinated through that sense of center of mass. I see no need to release anything as he is never inhibiting the predetermined center of mass flow. He is able to contract and pull his appendages around that core control center in any way he feels a need too in a 360 degree sphere.
His center of mass flow starts moving into the new turn right from the fall line. I see no need for weight shifts here or there or parallel shafts or inside ski first or any of that stuff. He is not coordinating the center of mass from from the feet he is coordinating the turn and feet from the center of mass itself.
All he needs is little nudges here and there from the feet, arms, core and every thing in between, from any position he has them in. on cue from that center of mass to keep things right on target in the fast lane. I am only just beginning to understand this kind of skiing.
I see a superb athlete who can blend movements in ways few bears could even imagine.
