Very true, Bud. And I can prop myself solidly in the back seat, with no chance of ever pronating onto the front of my foot,,, and procede to make perfectly exectuted arc to arc turns. Or I can lift my outside ski and make a perfectly clean carved turn on my inverted foot, while weighting the heel or ball, which ever I choose. And people CAN learn to ski without ever going to a bootfitter to rectify their mis-alignment issues.
Sure we can ski in inefficient states, and do so quite well. The point is, what ARE the most efficient
bio-mechanical approaches, and how can we help students learn to use them?
A fore/aft centered stance allows the foot to employ its full balancing capabilities. It also allows the muscles of the rest of the body to most relax. A pronated foot directs pressure to the turning edge of the outside ski. Exactly what serves us best. Counter allows a skier angulate and balance with the greatest effectiveness at big edge angles. It also aids in helping the outside foot pronate. If skiers change pressure to the old inside foot early in the transition cycle, while the old inside leg is still flexed, the CM generally trails that lead foot and needs to be moved forward prior to the start of the new turn to assume an efficient fore/aft centered stance.
Gait mechanics promote the attainment of all those things, and all those skiing efficiencies. No, it is not an exact match. We don't swing our arms, we don't actually stride forward with the new swing foot to the degree we do when walking. But the base movements ARE quite similar, and feeL so when you do it,,, and the results provide exactly what we want in achieving all the ideals I suggested above.
Bottom line: yes, we can ski in inefficient states. I do it, I teach it. It's important to know how. But it's equally important to know what efficient states are, and have numerous ways of achieving them. Gait mechanics is one. It's a tool. That's all.
|This is not one of Newton's laws!
That too is very true. Though if Newton came personally on Epicski to expain one of his laws, I'm sure there would be some who would jump in the mix to challenge him.
"I knew Jack Kennedy..... You're no Jack Kennedy, Rick." Yeah, yeah, I know,,,, it's just a joke.
Gotta tell you guys; it's tough as a race coach writing about gait mechanics. I keep auto typing it GATE.
