Which gait configuration is described as the most energy-efficient?

• A. Fast pattern and maximal speed
• B. Slow pattern and short steps
• C. Normal pattern and normal speed
• D. Wide base pattern and slow speed

Answer: (C)

Energy efficiency in gait is maximized when your step pattern and cadence match your natural, comfortable walking pace. This normal pattern at normal speed allows the body to exploit a pendulum-like exchange between potential and kinetic energy, minimizing muscular work per distance. Going faster than this increases energy cost due to greater propulsion, braking forces, and air resistance. Going much slower changes mechanics toward longer stance times with more frequent transitions, which also raises energy expenditure. A wide base or very short steps introduce extra lateral or rapid acceleration/deceleration work, further wasting energy. So, the configuration with a normal pattern and normal speed best minimizes metabolic cost per distance.
