El estudio comparo el comportamiento y el desempeno tactico de jovenes jugadores de futbol de diferentes posiciones, durante una temporada deportiva. Participaron en el estudio defensores (n=seis), centrocampistas (n=15) y atacantes (n=nueve), (media=14.1 anos; desviacion estandar=0.6). Se aplico la prueba de campo de FUT-SAT, que posibilita la evaluacion de la incidencia de los principios tacticos ofensivos y defensivos, asi como el porcentaje de acierto ofensivo y defensivo. Para realizar el analisis de los datos se utilizo un ANOVA de dos vias para la comparacion de los principios tacticos en las posiciones (defensores, centrocampistas y atacantes) durante la temporada. Los resultados mostraron que los atacantes realizaron mas acciones en el principio ofensivo de espacio que los defensores y centrocampistas, durante toda la temporada ( p = .04). Ademas, se verifico una mejora del rendimiento tactico ( p =.001) y cambios en los principios de unidad ofensiva y cobertura defensiva, en todas las posiciones ( p =.001).  Abstract. This study aimed at comparing tactical behavior and performance of soccer players from different playing positions throughout a season. The sample was composed of defenders (n=six), midfielders (n=15) and forwards (n=nine) (mean age 14.1, standard deviation=0.6). The players were evaluated using the FUT-SAT field test, which allows the evaluation of offensive and defensive incidence of tactical principles, as well as the percentage of positive tactical actions. Data were compared by a two-way ANOVA considering the factor “playing position” (defender, midfielder, and forward) throughout the season. Forwards carried out more actions on the offensive principle of space and width than defenders and midfielders throughout the season ( p = .04). In addition, an improvement in tactical performance was verified ( p = .001), as well as some variations regarding the incidence of offensive unity and defensive coverage actions throughout the season in all positions ( p = .001).
