The aim of this investigation was to describe how the introduction of the five-substitution option affected football teams' running performance. A comparative analysis was performed in 17 professional football teams for the 2019-2020 (up to three substitutions) vs 2020-2021 (five substitutions option) seasons in . The five-substitution option increased the number of substitutions (from 2.9±0.1 to 4.2±1.0 substitutions/match, respectively; p<0.01, Effect Size (ES)=2.11) but it did not change the time selected for the first substitution (from 57.5±13.0 to 56.2±13.7 min; p=0.06, ES=0.1). Total running distance was similar between seasons but running distance at 21.0-23.9 km/h (from 3.0±0.4 to 3.2±0.4 km; p=0.01, ES=0.6) and at≥24.0 km/h (from 3.0±0.6 to 3.2±0.5 km; p=0.01, ES=0.3) were higher with the five-substitution option. These increases were associated with a higher distance covered by starting players (p<0.05) rather than an effect of substitute players.: With the five-substitution option, team coaches increased the number of substitutions per match which enhanced the possibilities of the team's staff to manage players' physical load. The five-substitution option allowed also increased running performance at≥21.0 km/h during the matches.
本研究旨在描述五名替补球员上场选项的引入如何影响足球队的跑动表现。对 17 支职业足球队在 2019-2020 赛季（最多可进行 3 次换人）和 2020-2021 赛季（可进行 5 次换人）进行了比较分析。五名替补球员上场选项增加了换人次数（从每场比赛 2.9±0.1 次增加到 4.2±1.0 次；p<0.01，效应量（ES）=2.11），但没有改变首次换人时间（从 57.5±13.0 分钟减少到 56.2±13.7 分钟；p=0.06，ES=0.1）。总跑动距离在两个赛季之间相似，但 21.0-23.9 公里/小时（从 3.0±0.4 公里增加到 3.2±0.4 公里；p=0.01，ES=0.6）和≥24.0 公里/小时（从 3.0±0.6 公里增加到 3.2±0.5 公里；p=0.01，ES=0.3）的跑动距离更高，因为五名替补球员上场选项。这些增加与首发球员的跑动距离增加有关（p<0.05），而不是替补球员的影响。：随着五名替补球员上场选项的实施，球队教练每场比赛增加了换人次数，这增加了球队工作人员管理球员身体负荷的可能性。五名替补球员上场选项还允许在比赛中增加≥21.0 公里/小时的跑动表现。
