Most published research about the injury-prevention effectiveness of including the Nordic Hamstring (curl or exercise) in strength training comes from professional or Olympic sports.
They have been investigated for their effectiveness in different populations. In young people, NHE reduces injury risk factors in as little as a few weeks.
Exactly what physiological or mechanical properties are altered by the systematic execution of NHE remains elusive.
We do know that the NHE leads to higher muscle activation than other hamstring exercises.
In several sports, neglecting hamstring and glute strength leads to imbalance-associated injuries. It's a great idea to include the NHE in any program.
