This study investigated the effects of an eight weeks exercise regimen with either Nordic hamstring exercises or dynamic hamstring stretching (DHS) on balance, range of motion, agility, and muscle performance in male soccer players with hamstring shortness.
Sixty participants were divided into three groups: NHE ( = 20), DHS ( = 20), and control (CO; = 20). The NHE group performed Nordic hamstring exercises, the DHS group engaged in dynamic stretching, and the CO group did not receive any intervention. Assessments were conducted before and after the interventions using active knee extension test (AKET), sit-and-reach test (SR), Y-balance test (YBT), Illinois agility run test (IAT), and countermovement jump test (CMJ).
The results showed significant improvements in measured parameters for both the NHE (AKET: 16.16%; SR: 11.33%; YBT: 16.25%; IAT: 12.84%; CMJ: 7.28%) and DHS (AKET: 2.17%; SR: 5.51%; IAT: 4.54%; CMJ: 1.26%) groups, while no significant changes were observed in the CO group ( ≤ 0.001). The NHE group demonstrated superior effects compared to the DHS and CO groups, except for the countermovement jump test.
The findings suggest that including NHE in training regimens is recommended, particularly for soccer players with hamstring shortness. Therefore, both NHS and DHS positively influenced performance, range of motion, balance, and agility. However, NHE proved to be more effective, yielding more improvements that are significant across the performance, range of motion, balance, and agility parameters.

本研究调查了为期八周的运动方案，即北欧绳肌练习或动态绳肌拉伸（DHS）对绳肌缩短的男性足球运动员的平衡、活动范围、敏捷性和肌肉性能的影响。
60名参与者被分为三组：北欧绳肌练习组（NHE，n = 20）、动态拉伸组（DHS，n = 20）和对照组（CO，n = 20）。NHE组进行北欧绳肌练习，DHS组进行动态拉伸，CO组不接受任何干预。在干预前后使用主动膝关节伸展试验（AKET）、坐位体前屈试验（SR）、Y平衡试验（YBT）、伊利诺伊敏捷跑试验（IAT）和反向纵跳试验（CMJ）进行评估。
结果显示，NHE组（AKET：16.16%；SR：11.33%；YBT：16.25%；IAT：12.84%；CMJ：7.28%）和DHS组（AKET：2.17%；SR：5.51%；IAT：4.54%；CMJ：1.26%）的测量参数均有显著改善，而CO组未观察到显著变化（P≤0.001）。除反向纵跳试验外，NHE组的效果优于DHS组和CO组。
研究结果表明，建议在训练方案中纳入NHE，特别是对于绳肌缩短的足球运动员。因此，北欧绳肌练习和动态绳肌拉伸均对性能、活动范围、平衡和敏捷性产生了积极影响。然而，北欧绳肌练习被证明更有效，在性能、活动范围、平衡和敏捷性参数方面产生了更显著的改善。
