I can see where this might make one-ski antics more challenging.
Do these limitations mean you attempt to keep your CM centered between your feet at all times to detect individual foot pressure-change as your gage of lateral balance alignment?
How you detect centrifugal force? Do you allowing relaxed arms to sway with the magnitude of pull to the side? Do you hold elbows/arms more out to the side than the rest of us to increase lateral force detection?
I bet you're already doing something like the balancing ideas above. Personally, I built a whacky device by cutting a 3.5" hole in the middle of a hunk of plywood and put a softball under it. Ends up standing about an inch off the floor. Also tends to settle into the carpet and so limits the range of tippage to topple.
HMmmm... would three ounces of weight at the ends of you ski poles increase detection of lateral and acceleration forces through your wrists?
Ummmm not sure about "detecting" centrifugal force.....
Yes - no input from proprioceptors ANYWHERE (the nerves to brain got mashed they think)....
I do not detect body position nor muscle tension..... sense of touch (light touch and pressure) work VERY well.....
My ears will tell me I am falling if I am not STRAIGHT.... I can learn to ignore ears if needed - but as I regularly fell over due to problem I tend to automatically want to react when they say I am falling. I do better if I DO NOT (my natural response is very often the wrong one as I do not know which way to move to correct)
As an example I would always scream when we skied up wind lips - my instructor got annoyed - I insisted I was falling - he watched. We discovered I stay at the same angle to my skis - so I am not doing the "natural" thing & moving forward to stay upright.... my ears notice & say I am falling... He had to stand at every windlip & tell me when to move forward until I learnt to react properly
I find skiing with 1 ski and 1 boot VERY hard - I just fall down....
We know from when I was learning to ski parallel that the lifting ski etc stuff worked BADLY for me.... I would spend so much energy & concentration on NOT FALLING that I rarely gained anything from the exercise.... WE developed a FIX... I would simply lighten the required ski... then work on tapping.... then extend the time between taps etc etc.....
Trouble with the 1 ski 1 boot scenario is tapping the boot works POORLY as an aid....
Generally speaking I ski BEST when I have NO POLES... then I can stretch my hands & so activate (prepare) my muscles a bit
HANDS/ARMS - No the instructors all LIKE my hand position... I may get the timing out in short turns a bit .... but they all commented this past season (all the non-regulars) on how much they liked the hands.... So it would seem I have a very standard type hand position for APSI type ski instructors
OH the other example - when I rollerblade they try to get me to extend time gliding on 1 skate. To do this we have cones & I lift at first cone & try to hold to second.... I can't really do this either.... UNTIL - instructor watched & noticed I do EXACTLY what I am told... ie they say "lift left foot" - I do - sounds easy yes? but NO.... normal thing is to weight transfer
then lift (implicit in the lift) but I JUST lift - no weight transfer first.... we are working on using my hands as a guide to teach me the transfer for this - work still in progress at a halt due to being in Ireland atm
