Physical performance of youth football (soccer) players playing in European and National Leagues’ matches

ABSTRACT

The current study assessed the physical performance of youth Greek football (soccer) players between the Union of European Football Associations (UEFA) Youth and National Leagues’ matches. This effort was based on 271 measurements of nine physical/motor activities recruited from 25 players with a mean age of 18.4 (±1.2 years) during August 2017 and January 2018 from official-matches of UEFA Youth (n=6) and National Leagues (n=16). Measurements were recruited using Global-Positioning-System Technology-(GPS) and differences were assessed through analysis of covariance. 56.0% of the players were 18.0+ years old, 52.0% were midfielders, and 56.5% of players’ participations were recorded in full time (90.0+ minutes). Between the two competitions of UEFA Youth and National Leagues’ matches, it has been found that there is significant difference only in mean number of decelerations (71.4 vs. 61.7, respectively, p=0.010). High mean levels of total distance-(TD), very high-intensity-speed-running-distance-(VHS), maximal-sprinting-speed-distance-(MS), high-speed-running-(HSR), distance/time-(D/T), sprints, number of accelerations and maximum-velocity-(Vmax) were noticed as well as in UEFA Youth Leagues’ matches but did not differed significantly in relation to counterparts (p>0.05). The researchers observed that youth football players displayed similar efforts in all matches maintaining a high level of physical performance, without separating the matches according to the competition, due to the educational behavior adopted within the football academy of the club.
