The purpose of this study was to test the hypothesis that converting to a forefoot striking pattern or increasing cadence without focusing on changing foot strike type would reduce biomechanical parameters associated with tibial stress fracture in recreational runners.

Previous work comparing acute adaptations to forefoot striking or altering cadence attempted to independently assess the effects of foot strike and cadence by having subjects run using a forefoot striking pattern without adjusting cadence and changing cadence while maintaining a rearfoot striking pattern. In our study, we aimed to capture how runners naturally adjusted their running pattern while being asked to focus only on changing foot strike or increasing cadence. Our goal was to study how natural adaptations to changing foot strike or increasing cadence affects tibial stress fracture risk during overground running in a single population by analyzing the following set of injury risk parameters: peak absolute free moment, peak hip adduction angle, and average and peak loading rates.
