I would suggest that the ability to "topple and recover with precision" is in fact part of being in dynamic balance that allows the expert to make effective use of the skis. It is intentional, and it is effective.

 

I might also suggest that it is an example of the balance process as described by Larsson and Major.

 

If the concept of balance is expanded to include effectiveness, function and intent, such moves are not out of balance at all from a skiing perspective.

 

From a pure physics perspective, any body for which all the forces acting on it are not in equilibrium is not in balance. Any other condition causes acceleration, a term that includes increasing speed, decreasing speed, changing direction, etc. A body that is accelerating in any sense of the word is not in balance. I don't find this to be a particularly useful definition for skiing, since skiing involves continuous acceleration. This may be why JASP doesn't like the term "balance." As far as physics is concerned, it's a pretty specific and limited concept.

 

and the justifications for skiing out of balance continues.... 

 

I give up...

So now I've managed to PO both BTS and JASP. I'm really doing well here.

 

I'm not trying to justify skiing out of balance. I'm saying that being able to use the tools effectively is a Biggus Dealus.

Don't worry I'm not PO jhcooley...heheh.  But I still give up....  :rolleyes

"If the force on a body passes outside its base of support, the body will be out of balance and topple, as we see in figure 1.16. That might sound like a bad thing for a skier, but as we'll see in chapter 9, the ability to deliberately topple and recover with precision is an essential skill that sets expert skiers apart from the rest."

It is also worth noting that in chapter 9, Ron talks about centrifugal force, not just centripetal reaction forces coming up from a rail, and introduces the term balance axis.

This topic is hardly new fellas but perhaps it's time to face the fact that you are in error, not the rest of the ski coaching and teaching world. Argue otherwise if you must but you are arguing with these authors who are well known and very well respected experts in the field.

DD,

One of your very well respected experts skied himself into a pair of knee braces!

In a nut shell skiing is about getting down the hill in one piece and being able to go up and do it again, so the humorous short version is:


1. Start with some sort of push off.
2. Avoid obstacles and control speed with turns.
3. Absorb bumps with some sort of dynamic motion.
4. Stop to able to go up again.

Taken for granted it must look good otherwise you get ridiculed by your mates. This portion leads to a bunch of techinical discussion on technique and such.

Cheers, time to go skiing.

Actually, if you do the hard yards, do the research, publish your findings along with conclusions, subject that project to peer review, maybe you will join the ranks of some of the truly great coaches. Of course here at Epic you will also join the ranks of people heckled by so many here who lack the professional credentials and resources to fund and conduct a study of that magnitude.
Every top program in the world bases their methods on just such research and development. That doesn't mean they all agree but they all do the hard yards. My feeling is reading these papers instead of dismissing them is the key to becoming a top coach and instructor. I respect those men and women who have gone before and shared so much with the rest of the ski world. I cannot imagine how much poorer we all would be without their contributions. My task is to pass on what was passed on to me, encourage others to read their works because their voice lives on even though they do not.

Very true JASP. I'm glad when those that know understand and share even though I may not understand at that moment as it does make one think and learn if one is open.

Cheers
