FOOT STRIKE PATTERN trends in sub-elite half marathon runners

Abstract

The purpose of this study was to examine the changes in foot strike patterns throughout a sub elite half-marathon and examine the relationship between foot strike pattern and race performance. Race participants were filmed at mile 2, 5.5 and 12.5. Video was analysed to determine if participants used a forefoot, mid-foot strike or rear foot strike pattern at each camera. Furthermore participants were broken down in performance groups of 50 based off of time taken to reach each camera. At mile 5.5 and 12.5 significant difference in foot strike pattern (P<.01) was observed; as well as significant linear relationships between performance groups and strike pattern (P<.01). Based on the present findings we hypothesize that when fatigued sub-elite half marathoners default to the most efficient foot strike pattern.
