Steady-state GRF impulse over mass ratio: vertical (left), anterior-posterior (middle), and absolute mediolateral (right). Impulses are calculated by integrating the GRF vector (over the entire step period for vertical, after midstance for AP and ML) and normalizing by Mtotalgℓ/g to be dimensionless.
