Definition

Sine wave is the English name of a principle introduced to ITF taekwondo by Choi Hong Hi. In a step or technique, the practitioner first bends the knees, then raises the center of gravity and finally lowers it until impact. The head follows a path resembling a sine curve. The falling body weight is meant to add power to the strike. The principle is visible mainly in the teul patterns and is one of the main differences between ITF and WT taekwondo, which lacks it.
