The Association Between the Acute:Chronic Workload Ratio and Running-Related Injuries in Dutch Runners:A Prospective Cohort Study

OBJECTIVE: To investigate the association between the acute:chronic workload ratio (ACWR) and running-related injuries (RRI). METHODS: This is a secondary analysis using a database composed of data from three studies conducted with the same RRI surveillance system.
