In respect of Chen..

Can some one explain to me how the use of the sine wave motion in TKD evolves greater force than that of the cetrifugal force employed by Karate-Ka?

Budo.

Judderman, If you could explain the "sine wave" motion to me then Im sure i could give you some sort of answer. If you are talking about centifugal force in striking then I would say that since a straight line is faster it has the potential to have more power. But I have to wait for your response to give an accurate answer.

Because you use them both together?

Oh no, not that new age stuff.

I love fighting those guys, timing the bounce, hitting them on the co-sine wave, tangentially, and up side the head right up the z-axis!

And my wife thinks my math degree was totally wasted!

WhaT I'm saying is that the sine wave pulse from the mingmen is from having the back curved to straighting of Kung Fu in sequence after/during the waist turning so the power adds on kind of like any technique that uses more than one joint ect like shoulder, elbow, wrist doing a punch. Maybe add to that something like that kinda stamping weight shift to front foot where you really feel the power going into the ground and back up your body. Maybe add to that other stuff too. Can't a guy learn from others instead of learning the hard way. Also, when I check stuff out, I actually try it or hit something because the feel is what we can understand better than just words. I want to share... like the feeling when I've gone to schools , of the friendships and liking the examples my teachers set for me. My goal is to combine, the best I can, all the energies

I am having a little trouble comprehending what you said. But as taught to me it involves bringing yur center of gravity above your lateral center (hara) so that your weight can be added to a strike.*

But as some of us have pointed out many times, in calculating pounds per square inch, mass takes a very big back seat to speed.

It's a marginal enhancement to power at best and at worst, well, you don't have a low center of gravity. I'll let the Akido and Judo players take over at this point because they can best explain what they do when someone puts their weight that high up...

* as an afterthought let me add that one of the mantras is we kick because it's so much more powerful and the Koreans won't allow punching to count in competition, so it becomes somewhat of an ancillary theory...

Using Tae Kwan Do from what I studied and practiced the most in college, the kicks paid off in real life. I know that the hand techniques were not my strong point. I've been looking into "shocking" power more than "penetrating"

Where you lost me was the, "the mingmen is from having the back curved to straighting of Kung Fu," since I have no frame of reference. Can you expand and clarify, please?

The back curved to straightening is seen " The Fundamentals of Pa Kua Chang Vol. 1 / The Method of Lu Shui-T'ien as Taught by Park Bok Nam Pages 159 and 160. Referance that the back is coiled like a cat ready to pounce#3 and also #4 about the ripple or wave.Please also referance Hsing-I Chinese Mind-Body Boxing by Robert W Smith Page 25 #3 the Primary Requirements including; A3 "Bear shoulders" and B8 the three straightenings.
