Relative total and high-speed (&gt;5.5 m s&#x2212;1) distances were averaged over fixed and rolling 60-s to 600-s epochs. Linear mixed models compared FIXED versus ROLL and assessed the influence of epoch length, playing position, starting status, match result, location, formation, and time-of-day.ResultsIrrespective of playing position or epoch duration, FIXED underestimated ROLL for total (&#x223C;7&#x2013;10%) and high-speed (&#x223C;12&#x2013;25%) distance. In ROLL, worst-case scenario relative total and high-speed distances reduced from 190.1 &#xB1; 20.4 m min&#x2212;1 and 59.5 &#xB1; 23.0 m min&#x2212;1 in the 60-s epoch, to 120.9 &#xB1; 13.1 m min&#x2212;1 and 14.2 &#xB1; 6.5 m min&#x2212;1 in the 600-s epoch, respectively. Worst-case scenario total distance was higher for midfielders (&#x223C;9&#x2212;16 m min&#x2212;1) and defenders (&#x223C;3&#x2013;10 m min&#x2212;1) compared with attackers. In general, starters experienced higher worst-case scenario total distance than substitutes (&#x223C;3.6&#x2013;8.5 m min&#x2212;1), but lower worst-case scenario high-speed running over 300-s (&#x223C;3 m min&#x2212;1). Greater worst-case scenario total and high-speed distances were elicited during wins (&#x223C;7.3&#x2013;11.2 m min&#x2212;1 and &#x223C;2.7&#x2013;7.9 m min&#x2212;1, respectively) and losses (&#x223C;2.7&#x2013;5.7 m min&#x2212;1 and &#x223C;1.4&#x2013;2.2 m min&#x2212;1, respectively) versus draws, whilst time-of-day and playing formation influenced worst-case scenario high-speed distances only.ConclusionsThese data indicate an underestimation of worst-case scenario running demands in FIXED versus ROLL over 60-s to 600-s epochs while highlighting situational influences.
