Page 1 of 6 Arm attacks use some part of the arm to attack an
opponent: Power comes from: - Wrist snap. Snap-twisting the hand
at moment of impact. - Hip snap. Snapping hips toward target a
moment of impact. - Knees. The International Taekwondo
Federation (ITF) also uses a controversial up and down knee
movement called the sine wave that supposedly adds power. -
Legs. Using leg muscles to drive off the ball of the trailing
foot. - Twisting. Twisting the upper torso into the attack to
add body mass to it. - Spinning. Spinning the entire body add
centrifugal force to the attack. Spinning increase the velocity
of the strike and thus increases its power. When spinning
footwork, coordination, and balance are critical. The spin may
continue after the initial strike and lead into additional
spinning strikes, or the spin may reverse directions after the
initial strike and lead to additional spinning strikes from the
other direction. - Next >>
