โฃโฃโฃโฃโฃโฃโฃThe Nordic Hamstring Exercise (NHE) is a popular exercise for reducing hamstring injuries, and has warranted its inclusion in the โFifa 11+โ and โGAA 15โ injury prevention programmes. โฝ๏ธ๐๐ฅ

Hamstring injury mainly occurs during sprinting and stretching actions, that is combined hip flexion and knee extension (Woods et al., 2004).โฃโฃ

The way the NHE works is by placing a large load from the individuals body-weight on the hamstrings as they lengthen from a flexed to extended knee position. This eccentric load requires high force, thus increasing the muscle activity of the hamstring muscles in isolation to stop you falling forward - this decreases injury likelihood by having a positive influence on the length-tension relationship of the hamstrings.๐๐ โฃโฃ

The addition of the NHE in a S&C program has been shown to create large increases in eccentric torque (Mjolsnes, et al., 2004), and a more recent study on active young adults demonstrated that just 4-weeks with a NHE program (twice a week, 3 sets of 6โ10 repetitions) reduces muscle injury factors (Ribeiro-Alvares, et al., 2018).โฃโฃ

All-in-all, the NHE is an effective exercise that can reduce hamstring injuries in field based sports by over 50% per 1000 hours of exposure, demonstrated in a meta-analysis by Al Attar er al. (2017). So - if you do not like doing Nordics - GET TO LIKE THEM! โฃโฃ
