Recent versus old previous injury and its association with running-related injuries during competition by SeRUN® running profiles: a cross-sectional study
Background: Previous injury in the last 12 months is the main risk factor for future running-related injuries (RRI) during training and competition environments. However, the relationship between a recent versus old previous injury and a new RRI has not been established yet, nor a separate analysis by different types of runners. Methods: An online questionnaire was sent to 6000 participants of a running event (10 km, 21 km and 42 km), 10 days following the event. The questionnaire included the following information: the presence and topography of new RRIs during the race, old previous injury (from 12–4 months before the race), recent previous injury (from 3–0 months before the race), running experience, training factors and socio-demographic characteristics. Univariate binomial regression analysis was applied to assess different associated factors, and multivariable binomial backward regression (p
