Which statement best describes stability during performance in relation to base of support and postural sway?

• A. A narrower base of support improves stability
• B. Minimal sway is always ideal; no adjustment
• C. A wider base of support and controlled sway enhance stability
• D. Balance depends only on footwear

Answer: (C)

Stability during performance comes from how the base of support supports the body and how the body manages small, ongoing adjustments. A wider base of support increases the area over which the center of mass can move without tipping, giving greater leverage to resist perturbations. At the same time, some sway is normal and useful because the body continuously makes small adjustments through ankle, knee, and hip strategies to keep the center of mass aligned with the base of support as movement unfolds. If sway is restricted too much, the system loses its ability to adapt to unexpected forces. So, combining a broader base of support with controlled, deliberate sway genuinely enhances stability during performance. The idea that stability comes from a narrower base or from footwear alone isn’t accurate because balance relies on dynamic postural control, not just one static factor.
