This study aimed to describe the worst-case scenarios (WCS) of professional soccer players by playing position in different durations and analyse WCS considering different contextual variables (match half, match location and match outcome). A longitudinal study was conducted in a professional soccer team. Data were collected from different WCS durations in the total distance (TD), high-speed running distance (HSRD), and sprinting distance (SPD). A mixed analysis of variance was performed to compare different WCS durations between playing positions and contextual variables, making pairwise comparisons by Bonferroni post hoc test. Positional differences were found for TD ( < 0.01, = 0.02), HSRD ( < 0.01, = 0.01) and SPD ( < 0.01, = 0.02). There was a significant interaction when comparing WCS by match half in TD ( = 6.1, < 0.01, = 0.07) but no significant differences in HSRD ( = 0.403, = 0) or SPD ( = 0.376, = 0). A significant interaction was identified when comparing WCS by match location in TD ( = 51.5, < 0.01, = 0.14), HSRD ( = 19.15, < 0.01, = 0.05) and SPD ( = 8.95, < 0.01, = 0.01) as well as WCS by match outcome in TD ( = 36.4, < 0.01, = 0.08), HSRD ( = 13.6, < 0.01, = 0.04) and SPD ( = 7.4, < 0.01, = 0.02). Positional differences exist in TD, HSRD, and SPD in match-play WCS, and contextual variables such as match half, match location and match outcome have a significant impact on the WCS of professional soccer players.
本研究旨在描述职业足球运动员在不同时长下按比赛位置划分的最坏情况场景（WCS），并考虑不同情境变量（比赛半场、比赛地点和比赛结果）分析最坏情况场景。在一支职业足球队中进行了一项纵向研究。收集了不同最坏情况场景时长下总距离（TD）、高速奔跑距离（HSRD）和冲刺距离（SPD）的数据。进行了混合方差分析，以比较比赛位置和情境变量之间不同的最坏情况场景时长，并通过Bonferroni事后检验进行两两比较。发现TD（<0.01，=0.02）、HSRD（<0.01，=0.01）和SPD（<0.01，=0.02）存在位置差异。在按比赛半场比较TD的最坏情况场景时存在显著交互作用（=6.1，<0.01，=0.07），但HSRD（=0.403，=0）或SPD（=0.376，=0）无显著差异。在按比赛地点比较TD（=51.5，<0.01，=0.14）、HSRD（=19.15，<0.01，=0.05）和SPD（=8.95，<0.01，=0.01）的最坏情况场景时，以及按比赛结果比较TD（=36.4，<0.01，=0.08）、HSRD（=13.6，<0.01，=0.04）和SPD（=7.4，<0.01，=0.02）的最坏情况场景时，均识别出显著交互作用。在比赛中的最坏情况场景下，TD、HSRD和SPD存在位置差异，比赛半场、比赛地点和比赛结果等情境变量对职业足球运动员的最坏情况场景有显著影响。
