Which concept refers to the technique of breaking balance by using shifts in body position and leverage?

• A. Balance displacement
• B. Leverage
• C. Fluid shock principle
• D. Reactionary gap

Answer: (A)

Displacing the opponent’s balance is about shifting their base of support by your body movement and the way you apply force, so their center of gravity moves outside their feet. This intentional shift creates instability and makes it easier to-control them or escape. By stepping, turning your hips, and using your body as a lever, you generate a moment that breaks their balance, which is exactly what balance displacement describes.

Leverage is a broader idea of using mechanical advantage, and reactionary gap refers to maintaining distance to react. Fluid shock principle isn’t about altering an opponent’s balance. The specific action described—shifting position to disrupt the other person’s balance—fits balance displacement best.
