The aim of the research detailed here has been to assess the frequency with which football players engage in technical activity of various different types, in relation to seven phases of a game associated with changes in match status. To this end, 2016-2017 domestic-season matches in Germany's Bundesliga were analyzed, the relevant data being retrieved using an Opta Sportsdata Company system. Technical activity taken into consideration included shots, passes, ball possession, dribbles, and tackles. It was found that there was a large impact of frequency of shots on target (H = 466.999(6); = 0.001) in relation to the different match-status phases. Furthermore, moderate effect sizes were then obtained for frequency of shots (H = 187.073(6); = 0.001), frequency of passes (H = 133.547(6); = 0.001), and percentage of ball possession (H = 123.401(6); = 0.001). The implication would be that a team trying to change the match score of a game experienced at a given moment in a more favorable direction will need to raise the frequency and accuracy of passes, the percentage of ball possession, and the percentage of tackles ending in success. The maintenance of a winning match status requires a high frequency of occurrence of shots and shots on target as well as greater frequency and effectiveness of dribbling. The main finding from our work is that consideration of the consequences of a game presented in relation to seven potential phases to match status can point to a novel approach to analysis.
本研究旨在评估足球运动员在与比赛状态变化相关的七个比赛阶段中进行各种不同类型技术活动的频率。为此，分析了德国德甲联赛 2016-2017 赛季的比赛，相关数据使用 Opta Sportsdata 公司的系统检索。所考虑的技术活动包括射门、传球、控球、盘带和铲球。结果发现，射门频率对不同比赛阶段的进球频率（H = 466.999(6); = 0.001）有很大影响。此外，还获得了射门频率（H = 187.073(6); = 0.001）、传球频率（H = 133.547(6); = 0.001）和控球率（H = 123.401(6); = 0.001）的中等效应量。这意味着，一支试图在某个特定时刻改变比赛比分的球队需要提高传球的频率和准确性、控球率和成功铲球的比例。保持比赛的胜利状态需要高频率的射门和射正，以及更高频率和更有效的盘带。我们工作的主要发现是，考虑与七个潜在比赛阶段相关的比赛结果可以为分析提供一种新方法。
