Evidence Based Eccentric Strength Development: Hamstrings

Written By Aalijah David

The Nordic Hamstring curl is considered one of the top evidence-based exercises for developing eccentric hamstring strength. This can be a critical component for ensuring risk of injury declines, as well as increases in performance beginning to arise.


Multiple high-quality studies and systematic reviews support its effectiveness in increasing eccentric hamstring strength and reducing hamstring injury risk by up to 50–70%, especially in athletes.


The NHC heavily loads the hamstrings eccentrically, which is crucial because most hamstring injuries occur during the eccentric phase of sprinting (e.g., terminal swing).


What is needed? Simply an anchor for your feet, or someone to help you throughout the movement. You can add resistance bands to aid you throughout the movement as well.


The Nordic curl is considered one of the few exercises that allows for a maximal eccentric load without the additional need of external weight. But, do not get it twisted, there are multiple different ways to add load/resistance to a Nordic Curl. As you slowly lower yourself, your hamstrings resist gravity while lengthening—this directly trains eccentric control, a vital but often overlooked quality.

 

Why might a simple gym goer or weight lifter benefit from adding the Nordic Curl into their training regimen?
