The Five-substitution Option Enhances Teams ’ Running Performance at High Speed in Football
Int J Sports Med DOI: 10.1055/a-1982-9808The 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 LaLiga. 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 performan...
