Despite decades of continued efforts in research and practice, sprint-related hamstring injuries (sHMI) are still an unresolved issue in football.
📌Although improving hamstring strength (force capacity) has been proposed as an effective solution in some studies, the most recent meta-analyses show that hamstring strength capacity, as assessed and developed with a practical exercise such as the “Nordic hamstring” curl is not a sufficient factor for sHMI risk estimation or prevention.
📌In this context, the multifactorial feature of sHMI requires to consider a multifactorial and individualized approach of the risk puzzle, and we suggest centering this approach around the main injury mechanism during high-to-maximal-speed running.
📌If sHMI are seen as an overall imbalance between hamstring muscles strain incurred during the sprint task and their capacity to withstand that mechanical strain, an optimal prevention strategy should focus on (I) developing the capacity, but also (II) reducing the strain.
