Demandas de carga externa y diferencias posicionales en partidos de fútbol formativo de elite mediante GPS

Abstract

This research studies the physical load demands on Argentinean youth soccer players during official matches, categorized by position and division. Data was collected from youth players of Club Atlético Vélez Sarsfield, member of the Argentinean elite soccer league. Players who completed entire matches (186 players across 114 games) were included, excluding goalkeepers. GPS Catapult was employed to analyze running demands (total distance, sprint distance, distance at speeds exceeding 19 km/h, maximum velocity) and acceleration variables (player load per minute, maximum acceleration, maximum deceleration). The non-parametric Wilcoxon Test was used with a significance level set at p < 0.05. Significant differences were found between youth ages across most variables, excluding 8th and 9th divisions due to difference in playing times. Central defenders showed the lowest values in distance covered and maximum acceleration, while center forwards and wingers displayed the highest values in maximum velocity. Argentinian players performed better compared to international data. This study provides insights to optimize performance and injury prevention in Argentinean youth soccer.
