Effect of 8 weeks of injury prevention training of modified FIFA 11+ on kinetics indices of vertical jump on elite handball players Download PDF

Introduction: Warm-up programs are one of the most common preventive programs for injury in various sports. These warm-up exercises have had a positive outcomes in reducing lower limb injuries, but it is unclear what changes have occurred in these exercises and how and by what mechanism they reduce the injury. Methods: The participants were the available young players (n=24) and adults (n=24) of the national league, the 48 subjects divided in four groups participated in this study. They were randomly selected from each group to two groups of 12 subjects of exercises and control groups. By using force plate and the Bosco test, various kinematics indices were evaluated. Results: The results showed that the training modified +11 made and improved Bosco, pre-stretch, balance and endurance indices in handball players. There was a significant difference at the post-test of Bosco, balance and power indices with both the pre-test scores and control groups. Pre-stretch index with pre-test score and endurance index with control group had a significant difference. Conclusion: The implementation of 8 weeks of training modified +11 resulted in a significant improvement in these indices compared to the control group, which only had their normal exercises, could be the cause of injury reduction. Therefore, it is suggested that a modified +11 program for handball players at all skill levels and age should be implemented to prevent injuries.
