The influence of time winning and time losing on position-specific match physical demands in the top one spanish soccer league

Abstract

The aim of the present study was to analyze the influence of time winning and time losing on position-specific match physical demands with and without ball possession in the top Spanish professional soccer league. All matches played in the First Spanish soccer league over four consec-utive seasons (from 2015/16 to 2018/19) were recorded using an optical tracking system (i.e., Chyro-nHego), and the data were analyzed via Mediacoach®. Total distance (TD), and TD > 21 km∙h−1 covered with and without ball possession were analyzed using a Linear Mixed Model, taking into ac-count the contextual variables time winning and losing. Results showed that TD and TD > 21 km∙h−1 covered by central midfielders (0.01 and 0.005 m/min, respectively), wide midfielders (0.02 and 0.01 m/min, respectively), and forwards (0.03 and 0.02 m/min, respectively) significantly increased while winning (p < 0.05). By contrast, TD and TD > 21 km∙h−1 covered by central defenders (0.01 and 0.008 m/min, respectively) and wide defenders (0.06 and 0.008 m/min, respectively) significantly increased while losing (p < 0.05). In addition, for each minute that teams were winning, total distance with ball possession (TDWP) decreased, while, for each minute that teams were losing, TDWP in-creased. Instead, TDWP > 21 km∙h−1 obtained opposite results. Total distance without ball possession increased when teams were winning, and decreased when teams were losing. Therefore, the evolution of scoreline significantly influences tactical–technical and physical demands on soccer matches.
