Abstract

We aimed to illustrate the change in the foot external eversion moment of habitual rearfoot strike runners when they immediately change their foot strike pattern to an anterior foot strike pattern. Eighteen healthy males participated and were instructed to run with their habitual foot strike pattern and a modified (anterior) foot strike pattern. From the three-dimensional coordinates of running (250 Hz) and the ground reaction force (1000 Hz), the foot external eversion/inversion moments were calculated. During the stance phase of running, the modified foot strike running exhibited a significantly larger peak external eversion moment than the rearfoot strike running. Our results suggest that changing the foot strike pattern from a rearfoot to a forefoot may increase foot eversion moments and susceptibility to overuse running injuries.
