Interesting perspective BigE.
Heh - as we know, WC video can be used to justify anything, I mean, why cherry-pick only the item(s) we want to promote? There's lots of other good stuff in there.
If we take it all as-is then that WC video suggests we should all:
- Use Random A-Frames and O-Frames,
- Use upper-body and whole-body rotary into turns while reaching across our body with the new outside arm,
- Lean heavily on the tail of one ski with the other ski pointing upward,
- Frequently lever onto the tails of both skis,
- Bend at the waist,
- Cross our ski tips (about :50 in and again at 1:01),
- Drag and lever on our ski poles for balance (about :12, :18, 1:25),
- Ski as fast as we can at all times while forcing hard turns as we careen down public slopes on the edge of control...
OK, maybe not.
The term "Efficiency" is one of those fuzzy terms that crop up frequently in an attempt to label something as 'good'.
Efficiency of what specifically? Edge-lock carving? But that's only efficient in the sense of least frictional resistance
in the forward direction along the edge and has nothing to do with efficiency of other things.
How about efficiency of muscular activity and energy usage?
Certainly doesn't seem like ski racers are trying to be efficient
in that area - but recreational skiers who ski all day certainly need it. Racers only need to ski for 30 - 120 seconds. They can expend great amounts of energy (and do) since they don't need to keep it up for very long. Not very efficient in that regard.
Then there is the efficiency of line choice
as combined with technique.
A purely carving technique would require rounder lines though a given course and that might not be fastest. A mixed-mode model of pivot-entry turns combined with carving might be a better choice in many cases. To attempt carving in some parts of the course might be terribly inefficient and pivot-entry turns makes no sense in long turns on a downhill course.
As to "The clock doesn't lie" - it most certainly does!
- It lies about everything except elapsed time
It tells us only how much time has elapsed and nothing whatsoever about how "good" the skier is nor whether their technique was particularly well implemented. A winning time only means the fewest seconds ticked by
- nothing else. A far better skier with ideal technique might have been about to win but lost a ski due to pre-release. When we use 'the Clock' to justify any particular technique as being 'good anywhere and all the time' we're simply employing a logical fallacy. The two are not related.
Heck, "Technique" used by WC Racers isn't really a technique at all, it's a whole gamut of athletic movements
on skis to control direction while maintaining the highest speed possible. Certainly there are a lot of techniques available to them and they've probably learned a great many of them for implementation in the moment - but each turn technique implemented is specialized and adapted to the needs of that moment only.
There is a misconception that "What they do on the World Cup is what everyone should be doing..." and I think that's just bunk. Look again at the video and you'll see what skiers must necessarily do in a WC Race.
Personally, I see athleticism forcing technique
and specifically see Athleticism-Based Outcomes rather than Technique-Based Outcomes.
But maybe that's just me.
