Abstract
The purpose of this study was to investigate the effects of a prolonged run on coordinative variability and how it relates to impact dynamics in forefoot runners during an exhaustive run. Thirteen individuals ran on an instrumented treadmill and were instructed to select a pace they can maintain for at least 15 minutes but no longer than 20 minutes. A post hoc analysis revealed two subgroups emerged. Eight individuals were able to maintain a forefoot striking pattern throughout the run (NCG: no change group), while the remaining five moved to a more rearfoot strike (CG: change group). The results demonstrated that the impact characteristics changed for the CG only. This was accompanied by changes in CV, suggesting that individuals reorganize their degrees of freedom as they fatigue. The reorganization of footfall patterns may represent an adaptation to meet energy requirements to complete the task.
