CVV, a good response. I'll try to address the points. I sincerely hope that I don't cause any offence to competition guys, as that's my intention!
In Geoff Thompsons book, "The 3 Second Fighter"...He recounts a story of a competition Karateka who got into an situation on the street, automatically threw a punch out of instinct and it landed. However due to the fact that his body was conditioned to "pull" the punch due to the rules imposed on him because of his sport, landed an ineffective punch. His opponent took it on the chin, and returned fire and gave him a pasting. Geoff was asked by the guy what went wrong, and he explained it was due to what he was training for.
Obviously I can not put this over anywhere near as eloquently as Mr Thompson but I'll try. When training we condition our bodies through repitition to make our techniques a reflective action. Competition sparring rules dicttates that excessive contact will result in a disqualification, therefore Compettion stylists have to train there bodies to automatically reduce the contact. They have to train their bodies to automatically reduce the contact of their strikes, because in the heat of competition they simply don't get the time to do it mentally.
I'd like to add the point that I am generlizing majorly, I'm just trying to convey the point of we get what we train for. I have never personally taken part in a competition, but I have sparred plenty of points fighters over the years. One thing I have constantly found is that once they land ippon (correct term?) they pull away, which generally ends in chasing them all the way into the wall, when we take them straight to the floor, and stamp on them. Under their rules, I get trounced. They're bloody quick.
With regards to the Kata, which I really don't want to get into a kata debate, these actually allow you perform the movements to their full motion. When you come to practice the bunkai obviously you can't twist someones arm out of its socket, but practicing the kata solo allows you to perform the full movement.
I have seen and personally dealt with alot of people with alot of intent, and although a huge part of the puzzle, intent is nothing without the ability to use it.
As I said previously, I hope I haven't offended anyone...just offering a point of view for the discussion.
