Asymmetry in movement is topical but poorly understood in terms of knowing how it relates to musculoskeletal health, and how it typically varies during an activity in otherwise healthy individuals. The aim of this study was to investigate how asymmetry of running kinematics changed over the course of a 30 minute, high intensity run in a group of healthy young adult males. Using 3D motion analysis, average, variability and asymmetry data related to ground contact time, stride time, duty factor, and relative phasing of heel strike to the opposing stride cycle were acquired. No effect of time on average or variability of calculated variables was observed and between-limb differences were small, but responses were highly individualised and metric-dependent. Caution is hence advised in use and interpretation of group analyses when asymmetry is a metric of interest.
