ground reaction force


Also found in: Dictionary, Encyclopedia, Wikipedia.

force plate

a device for measuring the force between a body or object and the ground (the ground reaction force). Often constructed from strain gauges or piezo-electric transducers. Also known as a force platform.

ground reaction force

; GRF force offered by support surface, equalling and opposing force due to body mass passing through the foot to the ground surface; GRF is resolved into vertical (counteracting body weight) and horizontal (leading to forward movement) components
