Measurement of ground reaction forces using unobtrusive, on-athlete instrumentation

The purpose of this research is to investigate the measurement and characterization of ground reaction force transmitted through the foot-shoe-ground interface during the course of athletic activity (e.g running) from unobtrusive, on-athlete instrumentation. Both contact (in-shoe load) and non-contact (centre of mass acceleration) forms of sensory means to evaluate ground reaction force, are under investigation. Instrumentation has been developed to simultaneously acquire in-shoe load and acceleration data and a signal processing method is proposed to determine ground reaction force data from the on-athlete instrumentation.
