Al Attar WSA, Soomro N, Sinclair PJ, et al. Effect of injury prevention program that include the Nordic exercise on hamstring injury rates in football players: a systematic review and meta-analysis. Sports Med 2017; 47:907–916.


Hamstring injuries are the most common non-contact injuries in sport1 and account for 40% of muscle injuries in football,2 where up to one-third recur the following season.3–5 The rehabilitation of players with hamstring injuries usually lasts more than a month, restricting the athlete’s performance and causing a financial impact on clubs.3 4 6 The Nordic hamstring (NH) exercise is a promising option to decrease the risk of hamstring injuries in athletes. However, results of randomised controlled trials have been conflicting.6–8


The aim of this review was to assess the effectiveness of injury prevention programmes that included NH exercise on reducing the incidence of hamstring injuries among football players.
