Testing and improving soccer shoe models is important because of the physical demands of the sport. However, sprint-specific activities can also influence sprint performance. The purpose of this study was to identify the effect of different soccer shoe models and the trial number on sprinting and agility performance. Twenty-five soccer players completed four straight-line 30m sprints followed by four change-of-direction (COD) sprints and after each sprint the shoe model was quasi-randomized changed. For straight-line sprinting, horizontal force-velocity-profiling parameters and sprint times were computed and, in the COD,-test, sprint time was measured. The results indicate that the trial number affects the ability to generate horizontal force more at higher sprinting velocities than at low sprinting velocities, resulting in nonsystematic variance in the shoe model analysis.
