The aim of this study was to investigate the effect of competitive football match play on hamstring strength and lower limb flexibility. Fifteen male international youth football players were included. Hamstring strength and associated pain ratings, ankle dorsiflexion, hip extension, knee extension and flexion range of motion were evaluated immediately post-match and at intervals of 24, 48, and 72 h post-match. Strength significantly reduced post-match (P < 0.01), mean difference -0.43 (CI : -0.56, -0.30) and 24 h post (P < 0.05) mean difference -0.12 Nm/kg (CI : -0.20, -0.04). The associated pain scores significantly increased at the post-match (P < 0.01, ES = 0.61) and 24 h (P < 0.01, ES = 0.55) time intervals. At the 48 and 72 h post-match tests no significant difference was found for strength or pain ratings. No significant differences were detected for any of the range of motion measures. Competitive football match play has a significant acute and transient effect on isometric hamstring strength and associated pain levels during resisted knee flexion in male international youth players. Range of motion measures appear to remain relatively unaffected by match play. Isometric hamstring strength testing and associated pain levels might be considered for inclusion in-season to monitor player's post-match hamstring recovery characteristics.
本研究旨在调查足球比赛对腘绳肌力量和下肢柔韧性的影响。研究纳入了15名男性国际青年足球运动员。在比赛结束后立即以及比赛结束后24、48和72小时对腘绳肌力量、相关疼痛评分、踝关节背屈、髋关节伸展、膝关节伸展和屈曲活动范围进行评估。比赛后力量显著降低（P < 0.01），平均差异为-0.43（可信区间：-0.56，-0.30），比赛后24小时（P < 0.05）平均差异为-0.12 Nm/kg（可信区间：-0.20，-0.04）。相关疼痛评分在比赛后（P < 0.01，效应量=0.61）和24小时（P < 0.01，效应量=0.55）时间间隔显著增加。在比赛后48和72小时的测试中，未发现力量或疼痛评分有显著差异。任何活动范围测量均未检测到显著差异。足球比赛对男性国际青年球员在抗阻膝关节屈曲时的等长腘绳肌力量和相关疼痛水平有显著的急性和短暂影响。活动范围测量似乎相对不受比赛的影响。可以考虑在赛季中纳入等长腘绳肌力量测试和相关疼痛水平，以监测球员比赛后腘绳肌的恢复特征。
