Bretty101 Posted February 18, 2002 Share Posted February 18, 2002 Hi all, Just out of interest which of you do your patterns sine wave style and which of you do them the more solid Karate Fashion? (if you know what i mean?) I do mine the more solid way because i don't think anyone has ever explained the idea of sine wave to me before. What are you thoughts?

KickChick Posted February 18, 2002 Share Posted February 18, 2002 What a good question!! This seems to be the primary difference in the pracrice of forms/hyungs between the ITF and WTF. The ITF uses a stepping movement for all hand techniques. This `stepping motion' is referred to by ITF practioners as knee spring or up/down motion. It causes the body to move in a "sine wave" (Hwaldung Pahdo) resulting in the whole body being involved at the moment of impact, blocking or attacking. This techniques is not just used for hand-techniques. It is used in ITF kicking techniques as well. Sine waving allows for greater power by utilising our body mass effectively and permits greater control over our movements. The Sine wave is (partly) created by effective use of the leg muscles which is also known as "Knee Spring". At the beginning of a technique you should "drop" your body weight, and then increase your height before dropping again towards the end of the technique. To understand this you really need to be able to see it performed. _________________ ITF/TKD Black Belt (1st dan)/Fitness Kickboxing Instructor (KarateForums Sensei) [ This Message was edited by: KickChick on 2002-02-18 10:07 ] Link to comment Share on other sites More sharing options...
SBN Doug Posted February 18, 2002 Share Posted February 18, 2002 Sorry, I only know sine waves from college calculus and physics. Then again, I'm in a Korean art too. Does it refer to a softer version of the pattern? Kuk Sool Won - 4th danEvil triumphs when good men do nothing. Link to comment Share on other sites More sharing options...
Cory Reynolds Posted February 19, 2002 Share Posted February 19, 2002 Ha ha! I was thinking the same thing as KSN when I read the name of the thread! I've never performed forms in the sine fashion, but from all the different times that I've seen it done I've thought that it looked rather inefficient. Even when done properly, I thought the practicioners looked un balanced (not to be confused with off balance) and like they were wasting energy. I'm curious if people have taken the sine motion and ever tried punching a body shield or some other target in this way. With the constant rising up and down and indirect placement of power, I'd think that it would cause anyone to stop practicing in this way if they were trying to get more power. Anyone please let me know if they have discovered otherwise. Wise man once said "he who has big mouth has much room for foot." Link to comment Share on other sites More sharing options...
Bretty101 Posted February 19, 2002 Author Share Posted February 19, 2002 I kinda agree with all of you, tho i don't really understand the sine wave thing. I think along the lines of how we power test all our techniques by breaking a brick with them. Now i wouldn't use the sine wave to break a brick just straight line power and speed, but then isn't that just showing my ignorance. I'd hoped there would be some people who understand it so they could (try and) make me understand it. I'm very open minded but coming from a strong physics back ground i don't really understand it. Also having seen the power and solidness that Karate practitioners generate in their katas i try and imitate this. Bretty Link to comment Share on other sites More sharing options...

Bretty101 Posted February 20, 2002 Author Share Posted February 20, 2002 Yeah i understand your centre of gravity moves up and down like a sine-wave. We all do that a bit right?! Well if i'm honest, i think the bouncing thing is pants. I'd hoped someone would prove me other wize. I take it that no one here does sine wave?
