i was wondering, what are the peeps views on Sine wave? BS? i think its BS and some sort of psuedo fancy scientific name for hip snapping/ rhythym in the form.
im looking for more insights from other people though
All's I know is that Sine waves are math functions.
I remember back in the 80s and 90s never, ever hearing of a "sine wave" in TKD. My wife, her two brothers, and most of their friends were all TKD students, and it was never brought up.
Years later I hear about this "sine wave" thing, see it demonstrated, and couldn't help but think "wow, they've learned that gravity can help their strikes, how nice."
Yet they completely **** up the concept by bouncing up and down.
I remember when I first started training, our school went to a lot of open, point-sparring tournaments. We'd specifically train in our classes to "time" the bouncy-bouncy in order to catch the cat we were fighting against when he was in the air. Made for entertaining sparring matches (and a lot of faux-fouls when a guy was hit with a light contact technique he simply couldn't resist, making said technique look pretty comic-book-awesome) to say the least.

Without Sine wave, there would be just one less thing for people to argue about on youtube.
To me, it's a good example of how too much theory, when divorced from practicality, can be used to convince martial arts students to learn and practice movements that are ridiculous.
People who don't understand mathematical, physical, or other scientific ideas should not be teaching or explaining their martial arts using said ideas. That is what happened in this case. The results are not atypical.
I think it has less to do with the principles themselves being divorced of practicality and more to do with the people who created this application of principles not understanding the principles in question.

What do they have against the cosine wave by the way? It's probably closer to what they are trying to explain anyway.
