Well, you’re completely wrong about that.
ANY martial art will help you defend yourself to some degree, for the following reasons:
- You become stronger and faster.
- You learn to keep your balance.
- You become familiar with physical contact, which reduces the ‘shock’ factor should you be in such a situation in real life.
Aside from these three factors, individual martial arts have varying degrees of applicability to modern defense. Even Kata has value, because it helps build muscle memory that will come into play when you react ‘instinctually’. For example, after you reach a black-belt level in Goju-Ryu, you will have practiced certain grappling moves hundreds of thousands of times. It becomes a natural move that you don’t have to think about should someone take a swing at you. If you are startled, instead of your hands just flying up in front of your face randomly they will tend to move in ways that you have trained them to, without your thinking about it.
A somewhat funny example: When I went back to university in 1985 (after training 30 hours a week in the martial arts for a few years before that), I was sitting in a lounge reading a novel when a girl decided to play a joke and grab my book. So I’m sitting there reading, and this hand comes out of nowhere towards my face. My instinctive reaction was to grab her hand, twist her arm around in a joint lock, and pin her to the floor. The room went silent, and I was mortified for what had happened. She wasn’t injured, but I spent the next hour apologizing, and we wound up dating for a while.
The question is not whether martial arts will help you defend yourself, but how MUCH they will help you. I’ve said a million times that a black belt in a traditional martial art (Judo, Karate, Tae Kwon Do) is still no match for a very good, mean streetfighter. Unless the karate practitioner ALSO happens to be a skilled, mean streetfighter. Then the Karate will add to his skill set. But all things being equal, who wins on the street is mostly about attitude, viciousness, size, and surprise. Try using your fancy spinning back kicks when you are charged by a 250 lb maniac with spittle flying and perhaps a beer bottle coming at your head. And even if you land your kick, you aren’t going to drop someone cold with it unless you are very, very lucky. In which case you’ll have a 250lb screaming maniac pummeling you and biting your nose. If you’re not the mean type, chances are you’ll just turn into a blubbering idiot at this point.
The ultimate fighting championships favor guys who use lots of grappling techniques, but on the street you’d be wise not to try that unless you’re positive that the guy’s buddies aren’t around, or else once your arms are tied up in applying a joint lock you’re going to start taking some boots to the head.
Bottom line: You shouldn’t be involved in brawls with streetfighters ANYWAY. Use your superior judgement to stay out of situations that require the use of your superior skills. If you DO get into a self-defense situation, it’ll more likely be against a mugger, or an enraged driver, or perhaps a drunk somewhere. In which case, good martial arts training will let you handle the person.
