概要	This retrospective cohort study examined whether preseason running workloads protect against in-season hamstring strain injuries (HSI) in elite soccer players. Using GPS-derived external load metrics (e.g., sprint distance and sprint count) from the preseason and injury surveillance during the subsequent season, the authors tested associations between preseason exposure and later HSI risk. Higher sprint distance and sprint count during preseason were consistently linked to lower odds of in-season HSI, even after adjusting for key covariates. The study also reported acceptable discrimination for predicting HSI risk using sprint metrics and proposed practical cutoffs for identifying higher-risk players. Overall, the findings support sprint-focused preseason conditioning and systematic workload monitoring as actionable strategies for hamstring injury prevention in elite soccer.
