Rotation

Post by Lee » Friday 17 February 2006, 22:55

Hey Jacques,

You asked me in Grimentz why we in holland don't teach rotation and as far as i remember did not answer that question. well... here it is...

We do teach beginners rotation but we teach them to rotate along with the turn and not prior to it.

It is true that if you want to learn to cross-under it is difficult to change the rhythm and timing when you are used to cross-over. Most beginners stop learning after 10 lessons and think they can snowboard so they never reach the basic level you need to learn cross-under. And for those who always want to better themselve and learn new techiques it is difficult to find a teacher who teach them different techniques.

To bad that ECS was only a few days so there was not enough time to actually learn swiss style snowboarding. Two hours is just not enough to get into the rhythm. Maybe next time we could arrange a longer training session for those who want to learn it.

Yes, I would also like to take more lessons here in Austria, but I don't think they will teach me rotation and push-pull, so I feel I just have to persevere on my own.

The lessons Jacques gave really helped me a lot. I've been practising rotation and push-pull since discovering extremecarving.com 2 years ago, but there's nothing like having someone telling and showing you and then getting immediate feedback when you try. A longer training session at the next ECS would be great :) .

Lee, I remember you explaining the terms cross-under, cross-over, and cross-through during Jacques' lesson, but I still didn't really quite get it. I'm curious to properly understand these terms. Could you once again explain? Which one is rotation/push-pull?

There is a full article about these techiques on the bomber site

http://www.bomberonline.com//articles/cross_over.cfm

Cross-under is the push-pull technique. In german its called "Tiefentlastung"

Swiss style is tiefentlastung with rotation to initiate the turn

My avatar shows cross-over or in german "hochentlastung"

Hi Lee,

IMHO there are some differences between cross under (Tiefentlastung) and push pull. Even Jack Michaud recognized push pull technique to be more like cross through than like cross under.

Some time ago I tried to show the differences between these techniques:
Differentiation from low discharge (flexion) turns: On low discharge turns you start almost extended and lighten the edge by dynamic bending for eased edge change. In contrast on Push Pull turns which are started already low. Also the edge change takes place without clear edge discharge. In my eyes the Push Pull is a low discharge with changed timing, although it took it’s time, until I understood.

I’ll try to clearly point out the differences: In comparison to low discharge turn the lowering of your c.g. happens more gently and is still part of the steering phase. Rotation and edge change in push pulls take place later in the sequence than in cross under. This is after the bending, not before it. And again it is noticeable that the classical discharge is omitted. I think, straight contribute to Surf feeling.
Here is some more thoughts by skywalker ;) : viewtopic.php?t=1005&highlight=ectraining

Hi Skywalker,

Its very difficult for me to reference to text only. thats why i joined Jacques basic training. When i initiated the basic swiss style turn on basis of cross-under together with rotation it was marked as "good". After the training i had a conversation with Jacques about the technique.

In Holland there is a technique thats called "wedelen". Its when you go straight down the slope (not to steep), knees bend, and you just edge the board and "ride the radius". The legs are just following the board. These are "narrow" turns but you can apply this technique also to wider turns.

This technique is effortless, you dont put pressure anywhere. If you add rotation you get basic swiss style turning. Well thats what i understood :think:

Cross-through is a combination of cross-under and cross-over. With cross-over you build-up pressure in the second half of the turn to tighten it and propel yourselve into the next. With push-pull technique you absorb the rebound of the board in the second half of the turn by bending your knees.
