ANÁLISIS DE CARGA INTERNA Y EXTERNA DE FUTBOLISTAS JÓVENES EN JUEGOS REDUCIDOS // ANALYSIS OF INTERNAL AND EXTERNAL LOAD IN SMALL GAMES IN YOUNG FOOTBALL PLAYERS

Abstract

Today, small-sided games (JER) are utilized as training football methods. Objective: Analyze and compare internal and external workload in young footballers in JER. Method: Descriptive, transectional. Sample: 36 players (Age: 16,0 ±0,9 years; body mass: 64,4 ±8,7 kg; height: 170,7 ±6,7 cm) belonging to the football CDUC of Chile. Procedure: Measure the workload in possession (4vs4-5vs5) and polarized games (4vs4-5vs5 + goalkeepers). Materials: GPS Sport®, thoracic band receptor heart rate Polar® T31, laptop computer, software AMS Team® R1 2014.10, SPSS®. Conclusions: The type of small-sided game and the age group affect the results shown by players. Possession games with under 16 players showed higher mean values of external and internal workload with significant differences (p=<0,05) in different study variables. In the search for optimizing game performance it is crucial to take into account the particular features of scheduled training tasks and also the characteristics of players at different formative ages. © 2018, Universidad Autonoma de Madrid y CV Ciencias del Deporte.
