In a quick movement drill, which principle best promotes balance when initiating direction changes?

• A. Center of mass within base of support
• B. Tensing the jaw
• C. Looking at the feet
• D. Breathing rapidly

Answer: (A)

Maintaining balance in a quick-change movement hinges on where your body's weight sits relative to your feet. The center of mass should stay over the base of support—the area covered by your feet. When you initiate a change of direction, keeping the center of mass within that base lets you apply forces smoothly into the new direction and maintain control, reducing the risk of tipping or losing balance.

Tensing the jaw doesn’t influence how weight is distributed over your feet. Looking at the feet tends to focus attention downward and can misalign the body for the next move. Breathing rapidly can create tension and disrupt rhythm, which also makes maintaining stable, coordinated movement harder.
