Abstract

Purpose: Novice runners are at high risk of running-related injuries. However, their injury mechanisms are less well understood. The purpose of this study was to evaluate the effect of running-induced fatigue on foot roll-over pattern in novice runners. Methods: Eighteen (12 male and 6 female) novice runners participated in this study. Before and after the fatigue, plantar load distribution was recorded by Footscan system. Peak plantar pressure, peak force underneath of each zone and Medio-lateral force distribution ratio were calculated during forefoot push-off phase. Furthermore, temporal data such as time to peak force for each region and duration percent for each phase were calculated. Results: After the fatigue, an increase in forefoot and midfoot loading was observed. Results showed statistically significant reduction in the Medio-lateral force distribution ratio in forefoot push off (p=0.029). Moreover, timing percent of initial contact phase and forefoot contact phase were decreased (p=0.001 and p=0.009 respectively) and percent of forefoot push off phase duration was increased significantly (p=0.036). Time to peak force in the 4th metatarsal reduced. Conclusion: The findings of the present study demonstrated that running-induced fatigue caused load and plantar pressure distribution consequently, roll-over deviations in novice runners. These results may provide useful information related to several running related injuries.
