An investigation into two modes of eccentric hamstring training on parameters of strength and fatigue
resistance
David Roche
University of Salford, UK
Purpose:
Despite the high incidence of hamstring strain injuries in several popular sports, definitive research on their causation
and prevention is limited. Studies show fatigue and also hamstring eccentric weakness as causes for hamstring injuries. It begs
the question “which way may be the best to train hamstrings to prevent injury”.
Methods:
Eccentric hamstring peak torque and angle of peak torque toque were measured using the Kin Com dynamometer at
60˚s-1/s (type, 125 AP, Chattanooga, TN, USA) before and after a modified L.I.S.T fatigue protocol. Participants were divided
into two groups and underwent four weeks of eccentric hamstring training, then retested. The strength group used Nordic
Hamstring Curls and the endurance group used Assisted Nordic Hamstring Curls.
Results:
The results showed a significant difference in peak torque in both groups (strength: 0.00, Endurance: 0.01). Both
groups did not show a significant difference in angle of peak torque; however the results showed an increase to longer muscle
lengths of 18.28% and 26.95% for endurance and strength groups respectively.
Conclusions:
The strength training intervention shows the greatest improvement on both peak torque and angle of peak
torque.
