Traditional TKD practioners of the past had almost superhuman abilities due to their training. THEY could get away with high kicks, and jump spinning kicks, and reverse punches because they bloody trained 15 hours a day, EVERY day--and in their sleep, they dreampt taekwondo.
`Traditional TKD practitioners' were practicing Shotokan/Shudokan Karate in Korea. They learned their MA from Gichin Funakoshi or Toyama Kanken. Every—single—kwan founder studied Karate under expat Okinawan masters in Japan.
That was traditional TKD. Who are you thinking of in this passage? And that's still what `traditional' TKD is.
The kicks were never high originally. TKD kicks were low, like Shotokan and Goju-ryu kicks. Those high kicks didn't come in until TKD became a sport contest and demo activity. Jump spinning kicks... they didn't
do that stuff in the Kwan era!
Want some documentation for this? The first master textbook on TKD technique was Sihak Henry Cho's
Tae Kwon Do: Secrets of Korean Karate, published in 1968, the `state of the art' of TKD at the time. The title of the book presupposes the equivalence of TKD with the Korean variant of the art practiced in Okinawa and Japan as Kara Te. But there's more: Cho's book devotes 33 pages to the front snap kick and its variants; 53 pages to the side kick, 17 pages to the roundhouse, 4 pages to knee techs, and 15 pages to stamping and crescent kicks. Most of the kicks shown are depicted at low or middle height. The assumption was, you are going with the same bread-and-butter kicks as in Shotokan. By far the greatest emphasis is on the two basic kicks that the Kwan founders learned in Japan, the front snap kick and variants of the side kick. Go ahead,
try to find a spinning kick in Cho's encyclopaedic treatment of TKD kicks!

The spinning, jumping kicks didn't come in until the relatively late, sport-oriented phase of TKD, after Choi had been in effect banished in disgrace for his North Korean expeditions and the Korean government determined that TKD was more valuable to the Korean nationalist program as a competitive sport than as the CQ combat system of the military. I don't want to be disrespectful or anything, but why should North American and European practitioners of TKD, or anyone else, give a damn about what the Korean government decides is the correct profile of TKD?
And it still took them 20 years to earn a first dan! (Do keep in mind, they were pretty isolated from other arts).
From which other arts were they isolated? They were absolutely on the same page as the Shotokan teachers they learned the karate from which they taught in their Kwans. And they had practitioners of Jiu-Jutsu all around them; that had been taught in Korea in the early years of the Occupation, and there were still plenty of people around during the Kwan era who had been exposed to it. Hapkido was founded on an Aikido base...Do you really want to argue that the KMA masters were any more isolated than anyone else?
You, as a modern day person who does not have such time (or such teachers) can follow in their footsteps, but only as a dim shadow--like cartoonists tracing Michelangelo drawings. This isn't a criticism on modern TKD traditionalists, but a bow to the old guard, so unapproachable now--I just think the time for those drawn-out modes of training is over--and it should be! Different times, different enemies (and look at all the new choices form the other arts the traditionalist was simply ignorant of that you now have before you!)
The guy trying to defend himself in some suburb on the outskirts of Seoul in the early 1950s is very likely facing the same kinds of violent attacks that the guy getting hassled in some bar in Chicago, or North London, is. The techs that worked then work now. The current shiny new toys are no more complete SD systems than anything else is; if you acquire a good hard working knowledge of
any of them, you're going to do more than well, as long as you train it hard. Someone doesn't want to do that kind of training? Fine, it's not for everyone. But if someone is lucky enough to find an instructor who does train TKD—or any of the other variants of karate, or any of the CMAs, or whatever—for the purpose of damaging an attacker as badly as you think necessary, you're going to be able to do it and do it well.
Some TKD leader has to appear and make a real stand. "We're not going to do sports. No 'kids' classes either! This is dangerous stuff, adults only. We're going to prove it by fighting all the other arts--especially the most popular--and we're going to alter our techniques to become the best fighting system in the world. We'll have answers for everything, or TKD should die."
I see very low, snappy kicks; tricky, angled footwork; I see practical answers to the clinch and groundwork; I see more elbows and knee strikes; I see double knife hands becoming tight and fast;
All of those are part of the core technical repertoire of TKD, and of Shotokan, and of Tang Soo Do, and of all the other arts that spring from Okinawan karate. They were there in the system from the beginning and they're still there, whatever the WTF scoring system says. If some people, or a lot of people, don't train them that way, well,
tough. A .45 pistol will put a hole in your attacker the size of a half-dollar coming out his back, but only if you hit him. Target practice is
your lookout, not the gun's, eh?
I see no more forms practice (once and for all); I see knife and stick fighting.
The forms contain brilliant fighting techs, if you learn how to
read them as they were intended to be read. I agree with you to this extent: if you treat them as dances where a `block' motion is literally a block and a `punch' is only a punch, and you focus on the
performance of the patterns rather than on practicing the applications that follow from a shrew and realistic
analysis of the the patterns— well, that's
your failing. Karateka from Itosu on have told us repeatedly to learn how to interpret the forms as realistic guides to fighting tactics guided by effective principles. People can ignore their advice, and all the work that people have been doing during the past decade to decode those kata, but if you that, you can't blame the art for the fact that you ignore its technical content.
Will it be TKD? If you brought back one of those old-time TKD guys from 80 years ago, what would he think of TKD today? Go with the spirit, drop the form.
I suspect that if you brought Itosu or Motobu back and showed him the way most people interpret the immediate Korean offspring of their art, they'd say, `why are you so blind to the obvious?? Look at the bloody poomsae, don't you see that this is a wristlock leveraged into an armlock? This is an elbow to the face followed by a forearm strike to the exposed throat? Why are all you people so
illiterate that you can't read the simple instructions these forms are trying to give you?'
Sorry for the rant! That's just what I always wished TKD would do. It didn't, but I did find what I was looking for elsewhere. It COULD go in that direction; I doubt anyone sees the art moving in this direction, unfortunately.
I'm afraid this will fall on deaf ears, Flashlock, but I really wish you would take a look at Anslow's book on ITF tuls or—especially—Simon O'Neil's e-book on how to devise street-effective bunkai for TKD hyungs. O'Neil's book you have to subscribe to his newsletter to get, but in the interest of promoting the flow of ideas in the MA community, I'd be willing to make you a hard copy and send it to whatever address you gave me. Can't expect to get a better offer than that, now, can you?
