Abstract

Gender differences in kinetics may be associated with the incidence of specific overuse injuries. However, inter-segment foot kinetics during running have not been investigated between genders. The purpose of this study was to compare multi-segment foot kinetics during running between males and females. Eleven males and nine females ran barefoot with rearfoot strike at 3.3 m/s ± 10% along a 10 m runway. Segmental moment and power at midfoot and ankle in sagittal plane were calculated, and peak moment, positive and negative power were compared by gender. Peak positive and negative midfoot power were significantly larger in females than in males. These results suggest the soft tissues across midfoot contract more concentrically or eccentrically in females. The contribution of midfoot to shock absorption and forward propulsion seems to be different according to gender.
