"There are many different paths up to the top of the Mountain; but once you're there -all of the views are the same."
-This was my Korean TKD Master speaking about the differences between stytles of Martial Arts. I love the quote; and it seemed appropriate to share here in this thread. Its all about generating "maximum power", right? Everyone is built, moves, thinks, reacts... differently and so it seems only natural that we'd all have different ways of generating, harnessing and focusing power.
For me, I stumbled upon a technique which helped crystalize things for me. I was trying to experiment with "distance" late one night, and ended up taking a Front Stance with my lead foot about 12" away from a wall -with just enough room to hold a lunge punch in place. I started thinking about the very moment of impact with regards to my body's "structure" and I became acutely aware of the relationship between: 1) The power of my punch 2) the "driving force" on my back leg and 3) the reduction of weight on my front leg. The harder my fist "pushed" against the wall, the stonger my back leg drove into the ground, and the less weight there was on my front leg (almost to the point of picking it up).
Try puching a bag as hard as you can standing in front of it balanced on one foot. There will never be any power! The SAME principle applies with a kick too; but it is immensely complicated by having to maintain total balance, support, and driving power with a single leg!!
Any spinning kick attempts to replace a portion of the "driving" support force behind the kick with momentum generated by body movement -which CAN be very powerful. Jump spinning kicks replace ALL of the "driving" support force with body momentum -and so technique and timing have to be 100% in order to generate real power.
But here's the trick: If you had to stop 1" before the target, and then continue -how much of the original momentum could you generate again? People who are good at turning their hips over and extending their legs with "snap" can generate a fair amount of it back. Combine that with a good "power train structure" (stance at the moment of impact) -and BAM! There's a great kick in real time, with a full range of motion and at full speed.
I just don't see many MMA guys able to do this well. I don't think its a problem of the styles that are coming in as much as the practitioner's themselves. The typical MMA fighter seems to study Martial Art techniques as if the different moves were different Owner Manuals for some electronic device; if they read it once and understand it, they should be able to do it. I tell my TKD students all the time that they can't just "know" a technique in their head. Could you read a book or two about back flips, and then go try one successfully? No way! You're body has to learn it by trying it out a couple 1,000 times.
But I've never bought into "this" style over "that" either. Even in our own TKD Association there is so much variation... All different paths up to the top of the Mountain!
