A significant between-group difference was seen in favor of players having a previous hamstring injury over 6 sprints for maximal velocity (mean difference 0.457 m/s, 95% CI 0.059-0.849, p = 0.025) and mechanical effectiveness (mean difference 0.009, 95% CI 0.001-0.016, p = 0.02. Repeated-sprint performance was not impaired in football players with a previous hamstring strain injury; in fact, higher mean maximal sprinting velocity and better mechanical effectiveness were found in players with compared to without a previous hamstring
