All I know is the drill I mentioned works and the motive forces neded to pressure a tip while the ski is tipped on edge originate in our legs and are active in nature not passive. As Rick mentioned overdone it releases the tail, so to prevent that some plantar flexing of the foot is used. I know it sounds left of center but again playing with it first and then building the appropriate model is how Barnes led us to explore back ehen he was our ATM.
How this relates to core strength and turn shaoe is that a good stance allows us to use these movements effectively and a poor one doesn't.
very soft snow and brand new boots made for some sketchy skiing today, with a lot more "steering" than I would have wanted. Even so, the skis turn mostly by edging and pressure - and in this snow I played quite a bit with slow turns and the same occured, every time. Yes, sure I could pivot in the sense of twisting the skis, but the effect is so feeble that even then, just shifting the weight aft on the heel moves the tails so strongly that it's really pointless to say "I pivoted". It would be a lot more accurate and instructional to say that I skidded and/or pushed the tails around
Not to say that my overall movements were not of a rotational nature - for sure. But the turning did not come from any pivoting movement of any kind, just get the skis going, tip them a bit and shift weight. If you just compare logically the what, 20-50lb/ft I could apply to the ski via a twisting motion versus my entire 145lbs pushing on the tails without any effort... I managed the turn shape by the amount of edging and fore/aft and the way you pressure the ski and lever the boot.
The same think applies to "steering" itself - sure, perhaps I do guide the skis in some way, but that would certainly pale in comparison to the forces that the ski in movement on an arc can create... so focusing on managing these forces via edging and fore/aft makes a lot more sense...
So, I still have difficulty with this concept as applied anywhere other than walking pace on flats, where twisting the skis may make turning quicker. If you refer to the other meaning I saw Meta use, I find it weird to say that the earth pivots around the sun...
If it's used to describe an outcome rather than a movement, describe carving or skidding a turn as "having pivoted the skis around a pivot point 15m away..." sounds just weird... besides, what useful information would that provide? Simply saying I skidded or carved a turn at about the sidecut radius gives anyone a ton of info about what just hapened and pretty much what movements they need to do to replicate it...
Anyways, just my 2c - perhaps I just don't get it but that is the point of establishing a good solid dictionary, isnt' it? If the words don't convey precise info to any newbie... what's the point?
However - on the boots. THe new ones were tighter and allowed less movement at the ankle. Also, the upper cuff was somehow tighter and did not allow my calf to rotate easily in the boot. As soon as I switched back to my older boots, which allow quite some twisting movement of the ankle and the upper cuff somehow do not block my tibia/calf from rotating, I felt much more in control and in balance.
So I would have a question on this rotation of the tibia that puts the ACLs at risk - didn't find much searching on here - what is that? I think I do a fair bit of rotating the tibia outwards I would say...
