Despite the resources applied to the prevention of hamstring injuries in sport, between 2001 and 2014 the hamstring injury incidence and burden did not decline in male professional football.1 2 Consideration of alternative and complementary prevention strategies are needed.3 One-time only preseason screening for hamstring injury risk factors has limited value for preventing hamstring injuries.4 In-season monitoring of hamstring function has been advocated as a secondary prevention strategy.3 Since a player’s isometric knee flexion strength may decrease before suffering a hamstring strain (HS) injury,5 regular hamstring strength monitoring may be valuable. In-season monitoring can ensure players have restored hamstring muscle strength after the demands of a match and prior to undertaking high workloads in training or playing another match. Identifying a post-match impairment (‘subclinical stage of injury’),6 7 allows for early intervention and may be a practical way to lower susceptibility of hamstring injury (online supplementary material figure 1).
