...One group says that anytime you engage in a sport, ie: competing, that in the long run it'll hurt you, as far as being able to defend yourself goes. The other group begs to differ and states that competing is good, that people who compete can easily seperate the 2, ie: SD and sport, that they're often better conditioned both physically and can often take a hit better than most. ...
My thoughts/opinions are:
(and this is something I've given a LOT of thought to since the first day I put on a martial art uniform 20 years ago ...)
it really depends on your goals and focus.
My goal has always been to prepare myself for self defense. Period.
For me, every type of competition I've tried has always been about:
testing in a pressure situation one aspect of physical confrontations.
So "winning" any competition is always secondary to preparing myself for hand-to-hand combat.
A few examples:
• Competing in form/poomsee, I am testing whether I can execute precise, effective technique and body movement while nervous and in a situation where there are no "stop and do-overs".
If I find out, for example, that the judges are looking for extraordinarily long stances? (Shrug) too bad. Stances that are TOO long are not effective for fighting. Guess I'll just take the hit in my scores.
If I find out that judges will dock my scores for using anything but short walking stances? (Shrug) too bad. Deep stances are sometimes needed for stability. Guess I'll just take the hit in my scores.
Judges can tell me if I get a trophy or not, but me "winning" or not is all in MY mind: Did I perform WELL (win!), or did I flub under pressure? (lose..)
• Competing in point-style sparring, I am testing whether I bridge the gap and get my full-speed, full-power strikes EXACTLY where I want them (i.e., with ONLY as much contact as is allowed) while simultaneously avoiding and/or blocking incoming strikes.
After all, sometimes getting hit in the first contact can END a self defense situation badly – what if it were a lucky knockout strike? A knife? A stun gun?
But I am going in with combinations and won't be stopping until there is a break called. No kamikaze quick-touch for the point win attempts. That may win point matches but loses in self defense.
• Competing in WTF/Olympic style: I am punching them — HARD since it is a full contact sport. I don't care if it gets me points or not. I don't rub my chest againt my competitor until the ref breaks us to kicking range. I don't CARE what is good tactics for getting the most points. What matters is, can I keep from getting knocked out? Can I hit them hard — and maybe even knock them out?
In a nutshell, I am conforming to the rules of any given competition but I WILL NOT "game the game" just to win because it isn't worth the bad habits training those strategies may reinforce. I will fight as close as I can to real combat while staying within the rules.
Sure, something like UFC or other mixed martial arts may allow me to DO more, to train more aspects in a single event, but I've got to keep the overall picture in mind:
No matter how good I am, there is a significant chance that I could (even if I "win"!) receive an injury that would render me vulnerable for a few days, a few weeks — maybe even an injury that would keep me from training for years or the rest of my life!
I train martial arts to keep from getting beat up. Climbing into a MMA cage is a good way to get beat on — hence, counter to my goals and objectives of training.
Not to mention, I don't want to HURT people for entertainment. I'm not saying my techniques are "too deadly for the cage." But I have a pretty good punch, some pretty good kicks. Chances are, somebody could get hurt badly.
If modern medicine could go ZAP and make us all better immediately after the fight? Heck ya, it would be interesting and maybe even fun (knowing my opponent will not sustain serious injuries that affect his life).
So to sum it up, yea: you fight as you train. If you are spending significant time training specifically to win under a specific rule set and ignoring the "what ifs" of similar instances outside that ruleset, you could be training into yourself some less than desireable habits.
But if you keep focused on "Am I doing this just to win under this ruleset, or is this going to be an effective strategy/technique/method OUTSIDE of this controlled environment?" then ya, there are some great things to be learned in competition.
