Effectiveness of Nordic Hamstring Exercise Vs Static stretching in Hamstring flexibility among football players

Background: Hamstring injuries are widespread in regular activities and sports. Hamstring muscle group flexibility is essential for hip and knee movements as well as numerous functional activities. Nordic hamstring exercise (NHE) is an eccentric hamstring training that can both reduce the risk of hamstring injury and increase muscular performance. Muscle flexibility, strength, and endurance serve as essential fitness factors for injury prevention. As a result, the purpose of this study was to look into the effects of Nordic eccentric exercise and static stretching in football players. Methods: A Experimental study was conducted on 40 football players in the football academies, Bangalore, The assessment is done through AKE test. 20 participants (Group A) were allocate to the Nordic hamstring exercise(n=20) and (Group B) 20 participants were allocated to the static stretching for 4 week. Results: Nordic hamstring exercise and static stretching do not differ significantly. Both exercises are useful for increasing hamstring flexibility. The analysis shows that the average decrement in right leg ROM of group A was 15.65 and group B was 12.05 with p>0.05, indicating that there is no significant difference between groups A and B. The analysis also shows that the average decrement in left leg ROM of group A was 14.9 and group B was 12.95 with p>0.05, indicating that there is no significant difference between groups A and B. Conclusion: This study concludes that there is no significance difference between Group A (NHE) and Group B (Static stretching). Both stretching maneuver are effective in hamstring flexibility.
