What is the significance of ankle push-off power?

Ankle plantarflexion at push-off contributes 40-60% of total positive work during walking. Reduced ankle power (e.g., from Achilles tendinopathy) is compensated by increased hip extensor work.

How does walking speed affect ankle power?

Ankle push-off power scales approximately with the cube of walking speed. At slow speeds, hip flexion is the primary contributor; at natural and fast speeds, ankle push-off dominates.

Ankle Plantarflexion Power Generation Calculator

Calculate ankle joint plantarflexion power during push-off phase of gait. Peak ankle power generation (A2) = joint moment x angular velocity; typically 3-5 W/kg at self-selected running pace.
