Hamstring Strain Injuries (HSI) are one of the most common injuries sustained in team sports. HSI are the most common muscles injury in professional soccer, accounting for 37% (Ekstrand et al., 2011) and is the most common injury in AFL football (Orchard et al., 2011). It was predicted that in 2012 each individual HSI cost the AFL $40,021 (Hickey et al., 2014). Many protocols have been used to help prevent the risk of HSI, but none have been studied more than the humble Nordic Hamstring Curl (NHC). Let’s have a look at what it actually is and what the research says about it.
