The aim of this study was to identify relationships between the variation of match variables and football team’s match performance. Data from all 768 matches played at the group stage of UEFA Champions League from 2009-2010 to 2016-2017 seasons were analyzed. The correlations between the coefficient of variation of twenty match variables and the points of group stage were calculated. Autocorrelation function was used to identify the relationships between coefficients of variation of variables. Moreover, a generalized linear model was employed to identify the linear relationships between coefficients of variation and the probability of qualifying to the knockout stage. Inferences were made using the non-clinical magnitude-based inferences and evaluated by the smallest worthwhile change. Results showed that qualified teams showed more stable match performance on variables related to goal scoring, attacking and passing, while non-qualified teams displayed more stable match performance on variables related to defending. The coefficients of variation of variables related to goal scoring, attacking and passing had negative relationships with match performance, while variables related to defending displayed positive relationships. Findings of this study can provide useful information about the stability of match variables, contributing to the development of specific training interventions to enhance team’s performance in key indicators.

2010年至2017年欧洲冠军联赛小组赛阶段比赛统计数据和橄榄球队比赛表现的变化

这项研究的目的是确定比赛变量的变化与足球队比赛表现之间的关系。分析了2009-2010至2016-2017赛季欧洲冠军联赛小组赛中所有768场比赛的数据。计算了二十个匹配变量的变异系数与小组阶段得分之间的相关性。自相关函数用于识别变量的变化系数之间的关系。此外，采用广义线性模型来识别变异系数与淘汰赛阶段合格概率之间的线性关系。使用基于非临床量级的推论进行推论，并通过最小的有意义的变化进行评估。结果表明，合格的球队在进球，进攻和传球相关变量上表现出更稳定的比赛表现，而不合格的球队在防守方面则表现出更稳定的比赛表现。与进球，进攻和传球相关的变量的变异系数与比赛成绩呈负相关，而与防守相关的变量则呈正相关。这项研究的结果可以提供有关比赛变量稳定性的有用信息，有助于开发特定的培训干预措施，以提高团队在关键指标上的表现。与进球，进攻和传球相关的变量的变异系数与比赛成绩呈负相关，而与防守相关的变量则呈正相关。这项研究的结果可以提供有关比赛变量稳定性的有用信息，有助于开发特定的培训干预措施，以提高团队在关键指标上的表现。与进球，进攻和传球相关的变量的变异系数与比赛成绩呈负相关，而与防守相关的变量则呈正相关。这项研究的结果可以提供有关比赛变量稳定性的有用信息，有助于开发特定的培训干预措施，以提高团队在关键指标上的表现。
