Systematic review found that injury prevention programs that include Nordic hamstring exercises decrease the risk of hamstring injuries among soccer players

In this new systematic review, the authors included 5 studies (4 cluster randomised controlled trials and 1 cohort study) that investigated injury prevention programs that included the Nordic Hamstring exercise on the hamstring injury rate in soccer players. Pooled data of 4,455 individuals included in the 5 studies were analysed. A total of 315,992 exposure hours and 166 hamstring injuries were collected from the included studies. The pooled results showed 51% overall injury reduction per 1,000 hours of exposure for to injury prevention programs that included the Nordic hamstring exercise compared to controls (injury risk ratio = 0.49; 95% confidence interval = 0.291 to 0.827; p = 0.008). A limitation of this review is that it was not possible to evaluate the isolated effect of Nordic Hamstring exercise because the injury prevention programs included a variety of other exercises. Another limitation is that cost effectiveness was not considered as an outcome in the review, even though economic data have been published.
