Resumo(s)
This study examined the physical and technical demands of the 2010, 2014 and 2018 men’s FIFA World
Cups with special reference on extra time. Data were collected from 69 FIFA’s open-access match reports
(n= 3,238 individual players’ observations) and scaled by individual playing exposure. Players covered less
total distance (TD) from the 1st half to the extra time period (r=0.17–0.27; P<0.05). Moreover, the number
of sprints decreased from the 1st half to the extra time (r=0.13–0.25; P<0.01). However, substitutes who
started on or came in on the match throughout the 2nd half covered higher TD in the extra time
compared to the 2nd half (r=0.11–0.43; P<0.01), and compared to starters during the 2nd half and
extra time (r=0.11–0.36; P<0.05). Additionally, substitutes who started on, or came in throughout the
extra time covered higher TD and performed more sprints compared to starters during the extra time
r=0.12–0.23; P<0.05). Generally, no meaningful differences were observed in successful shots and dribbles
between periods of the match and between starting status (P>0.05). The occurrence of extra time
appeared to be detrimental to the work rate during the match, which can be counteracted by substitute
players.
