Boarders tell me that surfers have been rotating for years. The rotating certainly works in snowboarding. Here's a link that demonstrates it:http://www.extremecarving.com/tech/tech.html
. Plus the movies at this site are pretty neat to watch: http://www.extremecarving.com/movies/movies.html
. I learned alpine boarding after watching these movies all summer long in my office. How could you not after seeing these? Although I could never get to the point these guys are at.
Witherell and Evrard call the long, high speed GS, SG, DH ski turn the "Bicycle Lean Angle" (p. 79). Most World Cuppers today use a mini-GS turn in slalom, as well, as Olle Larson has explained in Ski Racing Magazine. I think Maier et a
l. do a contemporary version of the "Bicycle Lean Angle" by rotating some, but I wonder if he does it just using his waist. It would seem, IMHO, that you'd want to use the entire body. It's more efficient and keeps you centered where you want to be.
I mean, try it. (My dancer friend is big on this--if you read it's supposed to be one way or another, go out and try it.) Stand up and do a 1/4 jump turn. Can you do the turn by using just your waist? Even more basic: can you just stand still and rotate your body to one side just using your lateral obliques?
I'm not telling anyone to kill themselves, but go out on a steeper blue, crank it up straight for 60 or 70 yards and rotate. See what muscles you use. While you're having the ride of your life, try rotating the other direction and see what muscles you use for that. Probably good not to do this on a Saturday afternoon when it's crowded. Probably a good idea to ski the slope once at a slower pace to check it out, too.
Report back to all of us ASAP!
