On icy surfaces, which gait pattern reduces slip risk?

• A. Longer, faster steps
• B. Wider steps with more acceleration only
• C. Short and slow steps
• D. Maximal push-off

Answer: (C)

On icy surfaces, friction is limited, so the safest gait is one that minimizes the horizontal forces you need to generate and keeps your balance stable. Short and slow steps achieve this by reducing the forward and backward impulses required to move and stop, and by keeping the center of mass closer to the stance foot for longer so you stay more over your base of support. The slower pace also lowers momentum, so the body doesn’t have to produce large bursts of force to propel or brake. In contrast, longer or faster steps demand larger braking and propulsive forces, which can exceed the available friction and cause a slip. Wide steps with acceleration or maximal push-off similarly increase the forces and instability, making slipping more likely. So, taking short, cautious steps minimizes slip risk on ice.
