more than ANYONE it is essential that I only practice GOOD movements. (Hence the ski instructor/skate instructor sent me bits of book - I can practice 'positions' in front of a mirror until I learn them) I get sent home from skiing when I get tired - so I don't practice 'bad movements'. I'm not even allowed to stand badly in lift lines.
I am relying on LEARNING a movement pattern with NO proprioceptive feedback. My ONLY feedback is sensory.
I have skated more this summer than ANY previous summer (finally became able to skate without an instructor next to me 2 summers ago - it does help get time up - my instructor lives 3.5 hours away)
Also learnt slalom turns this summer (parallel turns last summer).
The feedback from my 2 ski instructors on the summers skating??? YES - I had tip lead going strongly(& other skate action) - for 1 hour - then it went - because "IT FELT WRONG ON SKIS". Other than that - BOTH agree that this summers skating has improved my lower leg work A LOT.
I did gain a bit of benefit the previous summer & the two before that. However ALL the time I spent learning STRONG skate TECHNIQUE did NOT inhibit my skiing - it helped.
I will check with the double qualified one - but I fail to see how having BOTH legs close together(side to side) but SPLIT fore/aft will cause an A-frame. I get a LOT more A-frame when I STRESS & head for my 'safety' position - feet side by side & WIDE apart.
Then again - I instinctively ski in quite a wide stance too - (never had a problem with wanting to keep legs close together
) I narrow the stance when doing shorter turns - but start sinking low & wide when they make me do big fast turns - it seems that is now my trained FEAR reaction.
Anyway - after all that guff... I think you end up learning the feel for how the movements occur - not the ABSOLUTE positions so much. This takes me longer - because I have less feedback mechanisms operating - but it is still much the same LEARNING going on. So all the skating in strong positions has improved my feel for the edges & the dynamics of how a GOOD turn will feel. I don't ski like I skate - because it has a BAD feel. The good movements still 'feel' the same - but different(my skates don't rebound for instance).
