One of the reasons Why some WC schools don't want to train people for torunment fighting and competitions is because its alot of work. The Trainer has to work hard to get you ready. That may take away from his classes too. You need someone who only does personal training for fighting in cage with no other engagements like classes three to four times a week.
Also I have found some schools are not interested in combat,sparring or even tournment fighting. So this is another reason why they don't. Also some people feel the essence of pure wing chun would be loss by evolving in a such away for a tournament. I don't know why.
anyway what do you do to increase stamina and muscle endurance?
I can understand the time constraints with regular classes, but one could add another class time slot for such intensive training or do private lesson. Have the student do conditioning with a personal trainer at the gym, and that would leave more time for training for the ring with focus on sparring and application.
I don't feel that true WC/Wt would be lost or watered down in the ring as much as people say. When I sparred in a TKD continious sparring match I never watered down the WC or slipped into another style to win. Straight WC all the way. And it worked.
Now, granted there was no ground fighting, but I feel that is irrevelant. Unless one is a WC stylist that feels that anti-grappling technique isn't "true" WT. Which, I think it's true enough.
It follows all the principles of Wing Chun to the tee as far as I can see. For Mook Jong Man: the 5 principles of Wing Chun are all present in anti-grappling. This being so, why would the "purity" of Wing Chun be compromised in the ring?
Okay, so you can't chian punch the opponent in the back of the head or neck. I agree with this, that is nasty and it is JUST a competition, no need to kill or paralyse someone. You can still pivot and chian punch the side of the head, etc.
Okay, no groin shots. That's fair and besides, they wear cups.
Okay, no eye strikes. I don't want to see purse fighters going blind or worse just to make a buck. So leave eye strikes out. But you can still utilize bui gee!
You can heel kick the knee just as you would in the street. They do allow knee and leg kicking even in the inside of the thigh. Now, do you really want to break someone's leg in a sport competition?
Okay, don't kick them in the head or face when their on the ground and your standing. Again you could really kill or paralyse someone. I see that as acceptable rules. But if your on the ground with them too, you can still use your knees and legs as you would with antigrappling, sneak a knee to the head when their on top of you, etc.
You CAN elbow the head, chest, Palm striking is allowed, heel kick, chops, hammerfist, hook kick, good old fashioned forearm shiver, planting the hand right in the face, neck takedowns, all legal.
So,
1. no groin shots
2. no biting
3. no kicking to head/body when opponent is down (so just wait until they get up again or follow them chainpunching!
4. no eye gouge
5. no headbutts (although I see the fighter's sneak those in all the time.
Would this really take THAT much away from Wing Chun?
