Key result
During the Nordic hamstring exercise, semitendinosus and biceps femoris activity were greatest, and the gluteus maximus to erector spinae activity ratio decreased with increasing knee extension angle.

The Nordic hamstring exercise significantly activates synergistic trunk and hip muscles, particularly the erector spinae and internal obliques, highlighting their importance in eccentric and concentric hamstring contractions.
Narouei et al. (2018) conducted a cross-sectional in Healthy (n=10). Nordic hamstring exercise was evaluated on Hip and trunk muscles electromyography (EMG) activity levels (p=<0.05). During the Nordic hamstring exercise, semitendinosus and biceps femoris activity were greatest, and the gluteus maximus to erector spinae activity ratio decreased with increasing knee extension angle.
