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.
