Force

These methods of generating reaction force are based on the fact that energy is being directed into the floor that bounces most all of the force back into the body, rather than absorbing it. Another way to generate a reaction force is when one hand performs a technique while the other hand is withdrawn in the opposite direction. The speed and scale of the movements of both hands are matched. This makes use of reaction force in two different ways. First, the pull back hand helps rotation to occur, because the force of the hand and arm being pulled back forcefully creates a forward movement on the other side of the body. Second, the pull back serves as a counter-balance for the technique being extended, so that if it misses the target, stability may be maintained.

Reaction force is also applied when actually striking a target with a technique. When a technique is finely focused, the body is so firmly connected to the ground that little or no force is accepted back into the body. If a technique quickly recoils after impact, none of the reaction force from the target can transfer back into the striking arm or leg and the impact duration is shortened, both of which increase impact force.
