What is the typical peak vGRF during running?

During steady-state running, peak vGRF is approximately 2.0-2.5x body weight. At sprinting speeds (>7 m/s), peak vGRF can reach 3.5-5.0x BW depending on the athlete.

Why does peak vGRF matter for injury risk?

Higher peak vGRF and loading rates are associated with tibial stress fractures, knee joint degeneration, and plantar fasciitis. Reducing vGRF is a key goal of gait retraining interventions.
