I skipped a bunch of pages, but have two points...
If you play golf, you want to play with the same fundamentals
as Tiger Woods. You won't play like him, but you want to use the same basic techniques. Right?
If you play tennis, you want to use the same fundamentals used by the Williams sisters or Roger Federer.
Basketball...Michael or Kobe.
I'm a certified rowing coach. I'm trained to teach beginning recreational sliding seat rowers to use the same fundamentals as Olympic rowers.
I've gotten recreational kayak stroke instruction from an Olympic gold medal winner in the fundamental stroke elements he uses.
As skiers and ski instructors, we do not use the fundamental movements the world's best skiers use. I'm not talking about tactical movements like dodging gates, I'm talking about the fundamentals.SlalomGS
The racers basically use different movements than we're trained to teach and use. Why? I haven't seen a WC racer flex their ankles/knees/hips to absorb forces at the lower half of a turn, then extend to release and steer into the next turn. There are some of the advanced "Stepping Stones" in the PSIA Alpine Technical manual that are somewhat like the racer movements, they could be taught to all skiers, but they aren't. Why are we trained to teach what we teach? Has this been evaluated? Show me the science. I've read some of the scientific articles about skiing for racing, and none contradicts using those movements for excellent recreational skiing at all levels. (The best scientific research into skiing I've found has been done by several European universities.)
Also, and this was probably said before, racers use any means they can to get their skis around the next gate. They want
to carve...that's fast. They must
make it around that gate, even if an imperfect movement is needed.
By the way, I haven't failed a cert exam. I ski as needed for the exam, then ski and teach otherwise when I feel the movement is better. I've been complemented by the ski school director on how well my students move.
