celtic bhoy Posted July 19, 2003 Share Posted July 19, 2003 Does anyone know when sine wave was introduced to ITF tkd. Link to comment Share on other sites More sharing options...
taichi4eva Posted July 19, 2003 Share Posted July 19, 2003 The sine wave was introduced into TKD by Choi Hong Hi. I think the movement was present in karate before, but I'm not sure of this. The sine wave movement is the only thing that separates WTF and ITF if forms are concerned. Hope this helps... Link to comment Share on other sites More sharing options...
John G Posted July 21, 2003 Share Posted July 21, 2003 I believe sine wave motion was introduced in the 1980s and borrowed/swiped/stolen from (of all places) Tai Chi (sp?) BTW ITF and WTF use totally different forms/tuls ... John G Jarrett III Dan, ITF Taekwon-Do Link to comment Share on other sites More sharing options...
Bretty101 Posted July 24, 2003 Share Posted July 24, 2003 (edited) A large amount of emphasis has been placed on sinewave over the last 10-15years. This has been done by the 'official' International Taekwondo Federation to distance itself from the rest of the ITF community. It's just more politics to drive taekwondo apart. Taekwondo is a fairly knew martial art (1955) but has it's roots in many other styles. In striving to be recognised as a martial art in it's own right TKD is evolving to be different. I think it's a shame the way TKD is becoming so distanced from arts such as shotokan which i think is so much more powerful without using sinewave. I agree with dropping into techniques but don't think a sinewave correctly discribes the motion. I'd like to watch someone break a brick with the sinewave technique! I do think if done well or 'correctly' it looks good in forms. But 90% of people who do it just look sloppy.

sethgraham Posted July 24, 2003 Share Posted July 24, 2003 maybe im just stupid but i have no clue what the sinewave is so if anyone would send me a link to a site or even xplain it themselves that would be great thanks 14,purple belt,TKDtalk to me i'm fun Link to comment Share on other sites More sharing options...
Bretty101 Posted July 24, 2003 Share Posted July 24, 2003 Well to give you some idea... It's a way of doing forms. basically you raise up and drop down into every technique using a combination of knee spring and long stances. your centre of gravity (hips) therefore move up and down in an osscilitary motion hence sinewave. The 'theory' is harnessing the power of the hips into the technique which i agree with in a way but i'm not sure bouncing up and down really does that. There is also a theory that each technique should start off slow and accelerate using the theory that force is a result of acceleration (F=ma). However this is nonsense because acceleration is actually the result of a force not the other way round. It's an interesting display of coordination which is required for power, but i can't say i agree with the way you go about it. Hows that? I believe you can see people doing the sinewave patterns (rather well i must say) on the official ITF website. Bretty Link to comment Share on other sites More sharing options...
AnonymousCoward Posted July 25, 2003 Share Posted July 25, 2003 If you have a look at this thread, there's a discussion on how to bounce: http://www.karateforums.com/viewtopic.php?t=8052 I wrote this reply about sine wave: If you look at the hyung as performed by the Taekwondo stylists on the Legacy CDROM set (they were chosen by Gen. Choi to perform the hyung) you will see that the sine wave motion is very slight indeed and I would probably consider that the students he chose were performing the patterns as he intended. Compared side by side to the sine wave motion performed by the ITU (http://www.taekwondo.to/patterns.htm) you will see that they do giant sine waves! I personally use a small sine wave in order to drop my (considerable) body weight at the point of impact, once the foot hits the ground. Along with the hip twist and small striking area, you can get a fair amount of power... Link to comment Share on other sites More sharing options...
MichiganTKD Posted February 9, 2004 Share Posted February 9, 2004 One of my students who is formerly ITF asked me why we don't do the sinewave. I told him because moving from point A to point B in a straight line is the most efficient way. To me, moving your body up and down is a waste of energy and puts your balance at risk. We always did basics and forms moving straight horizontally, relaxing during the step and focusing your whole body during the actual technique. My opinion-Welcome to it.

tufrthanu Posted February 9, 2004 Share Posted February 9, 2004 Well we do the chang hon forms the old way at my school no bounce, however, I think what they are thinking of is like in the case of a Low Block. If you start high and sink your whole body weight into it it will be more effective than simply using your arm. Its kind of like doing an uppercut by just twisting your hips, the wrong way, or by bending your legs and putting some body weight behind it, the right way. You create an upward wave which increases the amount of impact. Bretty is right also about the equation. In physics that works however when you are talking about hitting someone the equation should read F/m=a. Or the amount of force you use to move your arm(m) equals how fast it travels(a). Which in turn increases the impact. Long Live the Fighters! Link to comment Share on other sites More sharing options...
Spookey Posted February 9, 2004 Share Posted February 9, 2004 Dear All, Mass x Acceleration = Force! Realistically, in order to increase you striking power you must either increase your speed or mass! However, mass is like brain power you generally only utilize a percentage of a whole. By utilizing sinewave (lowering your mass at impact) you can utilize your mass more efficiently! TAEKWON! Do not defend against an attacker, but rather become the attacker...Destroy the enemy!TAEKWON! Link to comment Share on other sites More sharing options...
