No great offense intended, but this socalled expert should recheck her physics. Of course - no human motion can 100% be a simple mathematical model - but in this case it is simple to come pretty close. If an object moves with a steady motion in the horizontal direction and with a steady motion up and down (stopping at the same lowest and highest levels each time), this object is making a mathematically perfect sine wave. ITF techniques don't strive at moving up and down (vertically) in a steady motion, so this is a deviation from a mathematical sine wave, but the term is still relatively representative of the concept. It is not so hard to come close enough to this in my opinion. A note: the human body is not a single fixed shape object, so one need to fixate on a point that can move in a sine wave pattern. In the ITF encyclopedia, this is the knee when walking forward. A sidenote: in the ITF, the "sine wave"-term is now for simplicity used for much more than its initial use which was as I noted quite close to a sine wave.

The fact that it's called "sine-wave" doesn't mean one is supposed to actually do a true sine wave -- it's just a name for the technique. I agree that Physics is very used and abused in the martial arts -- but here they are just using the term to describe a motion that is up and down something somewhat resembling a sine-wave. There are other examples of abuse in physics in the martial ars much worse than this one. In this one they know that they aren't doing a sine wave -- it's just a name for the motion. And yes from a physics point of view motion up and down in and of itself is not going to add to horizontal power -- it's in the wrong component. But, since the human body is connected if I drop down and my dropping down causes me to propel my arm forward faster than staying level -- I've increased the power in the technique. Now, I am not part of the ITF and I don't use the sine-wave motion in my technique. I was taught to stay level so as to not "telegraph my technique". Which is the recognized fault of the technique, as Dave Steffen will atest to as well. But, I do think it is something that if done right can add to the power of a technique. But, to take a purely empirical point of view on this (which is what Physics is based on -- proving every theory with experimentation) -- you can just try it out. Now if we aren't taught to do this we probably aren't going to do it right, but I think you can at least get an idea for it. Go ahead and see if you can get more power in your technique with a up and down drop. Use David Steffens guideline on how to do it as much as possible and see what you come up with. Actually, if you want a true experiment you probably want a bunch of people doing this both inside and outside the ITF....

I admit that getting away for a week refreshes the mind and spirit. Your question is excellent. Billy Jack was a great inspiration based on the good versus evil. In my situation, growing up in a tough NYC neighborhood, being a skinny runt, and having one two many kicks in the rear by thugs got me to the study. Then we hit the hippy era and self-introspection. Meditation, religion, travel, changes, all lead to the study of the arts. Being a former athlete had a touch and attempting to curb my anger added. Throw in a little Shaft, Bruce Lee, and Vanishing Point= searching for a better tomorrow. In sum, a culmination of those variables melting together.

Darryl Hennigan, Jersey Long, Trevor Brown, Ashley Casteneda, Jean Claude Mourais (sp?) and Pietro Gigoletti, amongst others, were the champions from Chong Lee's JiDoKwan academy in Montreal that cleaned up at the Canadian Nationals - not the so called "North American" championships. BTW I've seen DoHee Lee play a few times; he was quite good for a front leg jab stylist. Quite good.
