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 (p < 0.01, ωp2 = 0.02), HSRD (p < 0.01, ωp2 = 0.01), and SPD (p < 0.01, ωp2 = 0.02). There was a significant interaction when comparing WCS by match half in TD (F = 6.1, p < 0.01, ωp2 = 0.07) but no significant differences in HSRD (p = 0.403, ωp2 = 0) or SPD (p = 0.376, ωp2 = 0). A significant interaction was identified when comparing WCS by match location in TD (F = 51.5, p < 0.01, ωp2 = 0.14), HSRD (F = 19.15, p < 0.01, ωp2 = 0.05), and SPD (F = 8.95, p < 0.01, ωp2 = 0.01), as well as WCS by match outcome in TD (F = 36.4, p < 0.01, ωp2 = 0.08), HSRD (F = 13.6, p < 0.01, ωp2 = 0.04), and SPD (F = 7.4, p < 0.01, ωp2 = 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.
