: The Nordic hamstring exercise (NHE) effectively strengthens the hamstrings, reduces the risk of hamstring strain, and induces fatigue in the muscles; thus, post-NHE recovery strategies should be optimized. Foam rolling (FR) is a widely used method, with the belief that it can speed up recovery. Thus, this study investigated the acute and 48-h effects of FR following the NHE on muscle stiffness, pain pressure threshold (PPT), flexibility, countermovement jump (CmJ) height, and maximal voluntary isometric contraction (MVIC). : Thirty-two active males were randomly assigned to either an FR group ( = 16) or a passive recovery (PR, = 16) group. Measurements were taken at three time points: pre-test, post-test_0h, and post-test_48h. Participants performed the NHE (3 sets × 10 reps) before the recovery interventions. Variables assessed included muscle stiffness (MyotonPro), flexibility (sit and reach), PPT (algometer), jump performance (force platform), and MVIC peak torque (dynamometer). : FR significantly improved acute flexibility (12.7%, < 0.001) following the NHE and prevented flexibility loss at 48 h, compared to the PR group. However, FR showed no significant advantages over PR in terms of muscle stiffness, PPT, CmJ, or MVIC, both acutely and at 48 h ( > 0.05). : FR is an effective acute recovery strategy for improving flexibility after the NHE but offers limited effects for muscle stiffness, PPT, and other functional muscle parameters, both acutely and at 48 h. Further research should explore the long-term effects and efficacy of FR across diverse populations and recovery scenarios.
北欧腿弯举练习（NHE）能有效增强腘绳肌力量，降低腘绳肌拉伤风险，并使肌肉产生疲劳；因此，应优化NHE后的恢复策略。泡沫轴放松（FR）是一种广泛使用的方法，人们认为它可以加速恢复。因此，本研究调查了NHE后进行FR对肌肉僵硬度、疼痛压力阈值（PPT）、柔韧性、反向纵跳（CmJ）高度和最大自主等长收缩（MVIC）的急性和48小时影响。32名活跃男性被随机分为FR组（n = 16）或被动恢复（PR，n = 16）组。在三个时间点进行测量：预测试、测试后0小时和测试后48小时。参与者在恢复干预前进行NHE（3组×10次重复）。评估的变量包括肌肉僵硬度（MyotonPro）、柔韧性（坐立前屈）、PPT（痛觉计）、跳跃性能（测力平台）和MVIC峰值扭矩（测力计）。与PR组相比，FR在NHE后显著提高了急性柔韧性（12.7%，P < 0.001），并防止了48小时时柔韧性的下降。然而，在急性和48小时时，FR在肌肉僵硬度、PPT、CmJ或MVIC方面与PR相比均无显著优势（P > 0.05）。FR是NHE后改善柔韧性的有效急性恢复策略，但对肌肉僵硬度、PPT和其他功能性肌肉参数在急性和48小时时的影响有限。进一步的研究应探索FR在不同人群和恢复场景中的长期影响和功效。
