: The extra-time (ET) period of soccer is competed during fixture congested schedules with often limited recovery time between matches. The aim of this study was to assess muscle damage recovery following 90- and 120-min (i.e., incorporation of ET) of simulated soccer match-play. : Twelve semiprofessional soccer players completed 90 and 120-min treadmill-based soccer-specific exercise in a counterbalanced order. Creatine kinase (CK), creatinine, urea, aspartate aminotransferase, perceived muscle soreness, pain pressure threshold, reactive strength index, countermovement jump height, and isokinetic strength assessments of eccentric knee flexors at 60, 180 and 270 deg‧s were taken at baseline and immediately-, 24, 48 and 72-hr post-exercise to assess recovery. : No significant between-trial interactions except for CK were found. Pairwise comparisons detected a 53% increase in CK at 24-hr (455 ± 29 μ∙L) following 120-min of simulated match-play vs. the corresponding post 90-min time-point (299 ± 29 μ∙L; < .01). The 120-min trial caused a 58% higher CK response at 72-hr (244 ± 25 μ∙L) vs. post 90-min comparisons (154 ± 29 μ∙L; = .02). No interaction effects were detected for any other recovery variables. Creatine kinase and perceived muscle soreness remained elevated up to 72-hr in both trials ( < .01). : These data indicate that 120 min of simulated soccer match-play delays the time-course of CK recovery up to 72-hr post-match. However, 120 min of simulated soccer has no additional impact on functional recovery and perceived muscle soreness vs. 90 min. Recovery should be investigated following 90- and 120-min of actual match-play. The study was pre-registered on the Open Science Framework (DOI: 10.17605/OSF.IO/VGU6T Date: 10/06/2019).
足球加时赛（ET）在赛程密集的情况下进行，比赛之间的恢复时间通常有限。本研究的目的是评估在模拟90分钟和120分钟（即包含加时赛）足球比赛后肌肉损伤的恢复情况。12名半职业足球运动员以平衡顺序完成了基于跑步机的90分钟和120分钟特定足球运动。在基线以及运动后即刻、24小时、48小时和72小时，测定肌酸激酶（CK）、肌酐、尿素、天冬氨酸转氨酶、肌肉酸痛感、疼痛压力阈值、反应力量指数、反向纵跳高度以及60、180和270度/秒时偏心屈膝肌的等速力量评估，以评估恢复情况。除CK外，未发现试验间有显著交互作用。两两比较发现，在120分钟模拟比赛后24小时（455±29μ∙L）时CK较90分钟相应时间点（299±29μ∙L）增加了53%（P<0.01）。120分钟试验在72小时时引起的CK反应比90分钟后比较时高58%（244±25μ∙L对154±29μ∙L；P = 0.02）。对于任何其他恢复变量，均未检测到交互作用。在两项试验中，肌酸激酶和肌肉酸痛感在72小时内均持续升高（P<0.01）。这些数据表明，120分钟模拟足球比赛会使CK恢复的时间进程延迟至比赛后72小时。然而，与90分钟相比，120分钟模拟足球对功能恢复和肌肉酸痛感没有额外影响。应在实际进行90分钟和120分钟比赛后对恢复情况进行研究。该研究已在开放科学框架上预先注册（DOI：10.17605/OSF.IO/VGU6T 日期：2019年10月6日）。
