What we actually do by performing this sine wave in Taekwon-do techniques is moving the center of our body mass by means of a motion, which would look like a sinus wave if we would draw it.
There are some key benefits to using sine wave that are linked to the training secrets of Taekwon-Do. Moving our center of mass in the motion of a sine wave requires us to keep our arms and legs bent while the body is in motion. To keep the arms and legs bent during motion we need to be relaxed. Relaxing the body adds speed to a technique because we are not all tensed up with one part of the body working against another. Small increases in speed produces large increases the power of a technique.
Secondly, when employing a sine wave we have to use the knee spring properly. That is to say bending the knee is what moves our body up and down as we move forward. Using the knee spring while our body is in motion allows our center of mass to travel along a curve, which by definition is another form of acceleration, which then helps us accelerate into a target. Explanation of sinewave by the founder of Taekwon-Do – General Choi Hong Hi – during a seminar in Poland (1999).
Finally, when using sine wave we are dropping our body downwards at the end of the technique with helps us use gravity to our advantage and keep our acceleration building until the point of impact. As you read the two, the concepts are similar, but yet, not exactly the same, although the end result is. These two terms, tend to be the most striking, however, both gentleman, also defined or redefined the terms used. Both sought to standardized the terms used in order to make teaching their arts not really more “simple” but more of an ability to teach as many as possible to promote their arts to the masses.
