If that's the idea you got from this board, then I apologize, that's a really stupid notion and whoever put that out there on this board needs to be noobified fast. I have sparred/observed many TKD fighters and to say that TKD as a whole emphasizes one leg or another is not accurate. Korean kicking is accompanied by footwork, jumps, and spins, so much to the point that there is no predominant leg. And furthermore, the only way to make such a strong black and white statement would be to statistically measure the amount of kicks a TKD fighter uses with either leg, by a reasonable sampling of the population.
Not rampart generalizing. Opinionated observation. I've been to several TKD schools, as well as several karate schools, and the primary kick for TKD is the back leg. This is not saying that this is the only kick that is at the disposal of a TKD fighter, it just seems to me (and from what I've read on the board) and most of the people of these forums: The back leg TKD kick is the most powerful and overall "best" (?)
That's what I was getting at - to say that a certain technique or a certain execution is more powerful over another is not accurate either because you can modify techniques to encompass different muscle groups and footwork to gain additional momentum. If you just want to compare the physics behind each movement, well I don't know that and if you can post whatever scientific basis you used to surmise this, well I'm sure it would at the very least make you sound more credible.
Also, you confuse me when you say that "Whether a kick is stronger thrown by the back leg or front leg is dependent upon footwork, hip torque, and individual's strength, NOT by whether you practice karate or TKD"
When you say that a kicker's strength depdnds on footwork, individual strength, hip pivot etc., isn't that the same as saying "How a school teaches it's students to kick" ? I'm not saying that ALL Karate sidekicks are more power than ALL TKD back leg kicks. Of course a 200 pound man will kick harder than a 80 pound child. I'm saying that (This is an opinionated observation!) if two, 200 pound men, one in TKD and one in Karate, both having perfect form, foot position, with the exact same physical strength threw a bacl leg kick and aslide up side kick: The one who used the sidekick would have a stronger kick.
Well the problem is, we won't entertain just any rant. Whatever case you are making against a TKD fighter, just want to make your viewpoints and facts are legit before making serious comparisons. If the arguments that you are posing are inherently incorrect, there is no point to indulge in your style war.
I'm still under the impression that this was a "Your style sucks forum". I was simply playing the devil's advocate. I appreciate your advice, but this seems like the place where I WANT to piss off an irritated TKD fighter.
