This study represents the first time that muscle damage, endocrine, and immune markers have been measured, together with activity profile, during a competitive soccer match. Seven semiprofessional soccer players participated in a competitive league match. Blood and saliva samples were obtained 1 hour before kick off and immediately postmatch. Global positioning system equipment was used to measure heart rate and activity profile data throughout the match. Percentage increase in creatine kinase (CK) and myoglobin (MYO) concentrations was correlated with the number of sprints performed during the match (r = 0.88, p = 0.019; r = 0.75, p = 0.047, respectively). Creatine kinase increased by 84% (p = 0.17) from prematch to postmatch, whereas MYO increased by 238% (p = 0.05). Players performed 39 ± 18 sprints during the course of the match. Cortisol increased by 78% (p = 0.103), whereas testosterone increased significantly by 44% (p = 0.004). No differences were seen from prematch to postmatch in the testosterone to cortisol ratio, immunoglobulin (Ig) A, IgM, or IgG. Sprinting is correlated with changes in CK and MYO and may therefore be associated with muscle damage in semiprofessional soccer players.
这项研究首次测量了竞技足球比赛中肌肉损伤、内分泌和免疫标志物，以及活动情况。7 名半职业足球运动员参加了一场职业联赛。在开球前 1 小时和比赛结束后立即采集血液和唾液样本。使用全球定位系统设备在整个比赛中测量心率和活动情况数据。肌酸激酶（CK）和肌红蛋白（MYO）浓度的百分比增加与比赛中冲刺的次数相关（r = 0.88，p = 0.019；r = 0.75，p = 0.047）。CK 在比赛前后增加了 84%（p = 0.17），而 MYO 增加了 238%（p = 0.05）。运动员在比赛中完成了 39 ± 18 次冲刺。皮质醇增加了 78%（p = 0.103），而睾酮显著增加了 44%（p = 0.004）。比赛前后，睾酮与皮质醇的比值、免疫球蛋白（Ig）A、IgM 或 IgG 没有差异。冲刺与 CK 和 MYO 的变化相关，因此可能与半职业足球运动员的肌肉损伤有关。
