Improvements in hamstring injury risk management strategies are necessary, especially in sports requiring ‘sprinting’ (ie, maximal acceleration and/or velocity). Sprinting represents about two-thirds of hamstring injury mechanisms.1 Several sprinting-related parameters are associated with hamstring injuries.2–5 Thus, this editorial aims to (1) emphasise the importance of sprinting and (2) provide general principles for practical implementation of sprinting interventions as a component of hamstring injury risk management in primary and secondary prevention.

Why should we consider sprinting as a piece of the hamstring injury risk management puzzle?

First, as an injury mechanism,1 sprinting represents one parameter on which we can act to reduce hamstring injury risk. Sprinting kinematics such as greater anterior pelvic tilt and thoracic side bending during swing phase4 and kinetics such as lower horizontal force production capacity during sprint acceleration5 are associated with higher hamstring injury risk.

Second, optimal exposure to maximal or near-maximal running velocity is suggested as a protective factor.3 Since an acute and rapid increase in sprinting volume is associated with markedly increased hamstring injury risk,2 a lack of regular preparatory sprint training may induce a higher risk of sprint-related injuries.6 Simply put, the hamstring muscles need to be prepared to safely provide the ‘function’ it is to perform, and …
