Obviously, it happens quicker in the shorter radius', as a relaxation/flexion of the legs allows the CM to remain unfettered as it crosses over the skis. In a longer radius, with greater time and distance covered, it occurs more visibly, with more extension usually involved.
The 1% which are cross unders are purely reactionary corrections, and have a distinct displacement of the skis from one side of the CM to the other.
I may be misunderstanding either the context ("elite" skiing) or be using the term (crossover) differently, but I disagree with the 99/1 statistic as applied to World Cup skiers: (1) On flatter sections of GS courses it is all crossunder. Watch the fluid crossunder of a Bode Miller and the quiet upper body at the flat section at the end of the course, while in a tuck; (2) in speed events, there's a lot of crossunder--there's a nice photomontage in LeMaster's book, with (Seitsinger? One of the German women, anyway, shown from behind in Super G or downhill); and (3) there's crossunder in slalom. Not sure what else you could call skiing a flush (other than, I suppose, knee angulation.)
One of the most interesting description/taxonomy breakdowns I've seen, of the variations in racing turns (applicable, by implication, to other skiing as well) is the following (long but eloquent), which was posted by an excellent skier and Masters' coach (I believe) in Utah going by the nom de post of Skiodor Doesgjdski on a different forum (at www.Nastar.com
). As I understand his post, there are three families of turn entries, Passive Crossover, Active Crossover, and Cross-under, and that the last two (active absorbtion turn and down unweighting) are just sub-variants of cross-under:
"There are three families of turn entries. All of this refers to GS turns.
Simply moving the CM of your body downhill, inside of your turn. Once you learn how to "Tip", this is the natural and easy way to entry the new turn. This is used in flatter sections of the course in both the "high tuck" and hands down. I'll leave it simple for now,.
This is the one you are asking about. Finishing the turn one pushes quickly, aggressive off the uphill inside edge and makes a very active crossover (arced turn) or to a Pivot Entry Turn (PET). Typically this is done to terminate any turn that is hanging on a bit and most always on steeper terrain. I haven't studied what percent of PET'S are started with an active uphill "release" but I'd bet it is the vast majority of PETS.
This is where the CM moves diagonally across and through, not UP and Over (Most Crossovers) and the skis "Swim" under and out away from you (though done is GS on flats at speed this is very common in Slalom Turns). This move is usually accompanied with some level of "Absorption" of the pressures in the turn to keep ski snow contact.
Active Absorption Turn (AAT)
This is where you must actively suck your legs up to you to absord the forces of the turn, Cross Under and extend to not get launched. Though this is used in GS, this is much more commonly seen in Slalom on steeper sections and in the ruts.
Quickly lower the CM to reduce pressure to allow the Cross-Under, I don't see this mover too often to be honest in WC events. I will watch closer. I don't imagine this is a move that is used in Nastar racing, so I was hesitant in mentioning it here. It was in Bob's link so I thought I'd address it.
These brief and inadequate descriptions provided I'd like to address the beauty of GS as compared to the other disciplines. As GS turns ARE what we do in Nastar (whether modified or full blown) the art of the GS turn in the context of the Nastar race course should not be ignored.
There is no one stance or position to execute a series of GS turns in any course. The racer that has the greatest repertoire of movements in their bag and can execute them where and when ever needed to negotiate the course and find the fastest line wins, period. Bode has a greater repertoire of movements executing GS turns on any WC GS course, this is why he can "See" where to find speed (he has the best Pivot, knows when to use Hip to de-angulate his skis, knows when press his feet forward to get his skis "hunting the fall line", etc.). He does this without too much thought, its instinctive at his level; it is instantaneous, it is outrageous talent. He is like Charlie "Bird" Parker, the great Jazz Sax player. Why was Bird so GREAT? Because he had more at his disposal, and endless talent where he could "hear" lines before he would play them in the complex matrix of a Jazz ensemble. It was based on more scales, more keys, more melodies, more technical facility all combining to make him fluent, flowing, without limits as he played extemporaneously and in stream of consciousness. Unreal! This is Bode in the GS course."
