Gi,
Let's take a hypothetical situation, and look at two arts which I respect, but which are at opposite ends of the Martial Art spectrum.
You have Mr Smith who has decided that he wants to learn Martial Arts for Self-Defence and joins a Shokokai Karate class.
You have Mr Jones who has decided that he would like to train to fight under a full-contact sporting system such as MMA.
Now let's say that Mr Jones and Mr Smith are the same age, and, provisionaly the same fitness level. They both put the same hours into their training.
If both Mr Smith and Mr Jones were attacked, I would bet 12 to the dozen that Mr Jones would be more likely to survive a violent confrontation than Mr Smith, despite the fact that Mr Jones was only training for a sport, due to the fact that whilst Mr Smith may have had some excellent teachings, and tried out various drills such as Kata Oyo, etc, Mr Jones has probably (having seen a lot of Karate Dojo and MMA gyms over the years) had more experience of actual full-contact training.
Now that's not meant to disrespect Shukokai, as my own background is in Shukokai, but it is an observation that most average Martial Art classes, despite protestations to the contrary, do not train in realistic and practical self-defence, and whilst I would never advocate the training of a sporting system to substitute proper self defence/protection training, it is MY opinion that your average Martial Arts athlete is going to be better prepared in a violent situation than your average Karate-ka or TKD stylist. And I say that as a Karate-ka of 33 years experience and a Yondan to boot.
Also, I have met very few Martial arts teachers over the years who have been involved in a live violent scenario, and I'm sorry to say that many of them who have claimed X ammount of fights are, I'm sorry to say, 9 time out of 10, BS'ing.
If pressed on recollection, they seem to have a very clear memory of the event, when in actual fact, after a violent confontration memories are fragmented.
I once met (another anecdote), who claimed to have fought off four attacker outside a nightclub once.
First of all, the noghtclub he named was the one I was Security Manager of, and I had no memory of the altercation, and second, he could describe technique for technique every moment of that confrontation, and how he would plan his next 5 or 6 techniques as in chess.
I don't know if you've ever seen Top Gun but...cough 'Bull sh*t' cough.
Ex SAS soldier and writer, Chris Ryan write that in a FUBAR situation where reation takes over from planning, he could only think three steps ahead, and he was trained to operate in one of the most elite Special Forces units in the World.
Your average Sesei/Sifu X has never had anywhere near that type of training.
