The aim of this study was to examine the influence of extra-time periods on physical performance profiles in elite soccer. Match performance data were collected from players (n=99) during the 2014 FIFA World Cup Finals (FWC). Performance was analysed per minute for total distance covered and distance run in 3 categories: =11.0 km. h-1 (low), 11.1-14.0 km. h-1 (medium) and =14.1 km. h-1 (high-speed). Additional variables such as the time spent in low, medium and high activities, maximal running speed and the number of sprints per minute were also assessed. Analysis of players who completed the demands of the full 120 min of playing time revealed that total distance, high-intensity running, top speed and high intensity activities declines by 12%, 18%, 3% and 15% respectively, from the first to the second half of the match
