橄榄球联盟的球员可能需要几天时间才能从比赛中完全恢复。在比赛中引起的肌肉损伤在球员恢复中起着重要作用;然而，预测赛后肌肉损伤的比赛的具体特征仍然不清楚。我们研究了职业橄榄球运动员肌肉损伤标志物与身体接触和高速运动相关的性能特征之间的关系。28名职业橄榄球联盟球员（15名前锋，13名后卫）参加了这项研究。从4场欧洲杯比赛中获得数据，在比赛前2小时、比赛后16小时和40小时采集血样，随后分析肌酸激酶（CK）。CK浓度的变化和物理接触和高速运行的标记，来自性能分析和全球定位系统（GPS）数据的数量之间的关系进行了评估。在来自性能分析的接触统计与前、后16和40 h CK变化之间分别确定了中度和中-大型效应量相关性（例如，后;总影响与ΔCK（r = 0.638，p < 0.01）和Δ% CK（r = 0.454，p < 0.05），40 h后）。此外，在高速跑和短跑的测量值与比赛后16和40 h背部CK的变化之间发现了中等效应量相关性（例如，高速跑距离与比赛后40 h的ΔCK（r = 0.434，p = 0.056）和Δ% CK（r = 0.437，p = 0.054））。我们的数据表明，肌肉损伤引起的专业橄榄球联盟比赛发挥在一定程度上预测的物理接触过程中引起的性能。此外，我们第一次表明，在背球员的肌肉损伤是由来自GPS的高速运行措施预测。这些数据增加了对橄榄球联盟中肌肉损伤原因的理解;性能标记可能用于定制橄榄球联盟比赛后的个人恢复策略和后续训练。
Rugby union players can take several days to fully recover from competition. Muscle damage induced during the match has a major role in player recovery; however the specific characteristics of match play that predict post-match muscle damage remains unclear. We examined the relationships between a marker of muscle damage and performance characteristics associated with physical contacts and high-speed movement in professional rugby union players. Twenty-eight professional rugby union players (15 forwards, 13 backs) participated in this study. Data were obtained from 4 European Cup games, with blood samples collected 2 h pre, and 16 and 40 h post-match, and were subsequently analysed for creatine kinase (CK). Relationships between changes in CK concentrations and number of physical contacts and high-speed running markers, derived from performance analysis and global positioning system (GPS) data, were assessed. Moderate and moderate-large effect-size correlations were identified between contact statistics from performance analysis and changes in CK at 16 and 40 h post-match in forwards and backs, respectively (e.g. backs; total impacts vs. ΔCK (r = 0.638, p < 0.01) and Δ% CK (r = 0.454, p < 0.05) 40 h post-match). Furthermore, moderate effect-size correlations were found between measures of high-speed running and sprinting, and changes in CK at 16 and 40 h post-match within the backs (e.g. high-speed running distance vs. ΔCK (r = 0.434, p = 0.056) and Δ% CK (r = 0.437, p = 0.054) 40 hrs post-match). Our data demonstrate that muscle damage induced by professional rugby union match play is to some extent predicted by the number of physical contacts induced during performance. Furthermore, we show for the first time that muscle damage in backs players is predicted by high-speed running measures derived from GPS. These data increase the understanding of the causes of muscle damage in rugby union; performance markers could potentially be used to tailor individual recovery strategies and subsequent training following rugby union competition.
