What is the ideal AP GRF pattern during running?

Equal braking and propulsive impulses indicate efficient running. Dominant braking impulse (>50% of total horizontal) suggests overstriding and inefficient foot placement.

How does step rate affect AP forces?

Increasing step rate by 5-10% reduces overstriding, shifting foot contact closer to the body's center of mass, decreasing braking impulse by 15-30%.

Anterior-Posterior Braking Force Ground Reaction Force Calculator

Quantify anterior-posterior (braking and propulsive) GRF impulses during gait. Braking impulse reflects overstriding; propulsive impulse drives forward acceleration.
