Resumen
(ES)El objetivo del estudio fue comprobar el efecto que tiene la fatiga inducida por RSA en el rendimiento
de los jugadores, en la toma de decisiones y en el tiempo de ejecución en acciones técnico-tácticas y
comprobar si existen diferencias entre categoría juvenil y cadete. En total participaron 31 jugadores de
fútbol formativo, 15 juveniles (16,87 ±0,64 años) y 16 cadetes (15,25 ±0,45 años). Se evaluó sin fatiga y
con fatiga el rendimiento de acciones técnico-tácticas con el Stroop Task Football Test (STFT). Para
inducir fatiga se realizó un protocolo de RSA entre las dos mediciones. El rendimiento de los cadetes
disminuyó significativamente en el tiempo de ejecución (57,67 ±3,79 vs. 60,76 ±4,59; p=0,006), la toma
de decisiones (61,25 ±1,39 vs. 60,13 ±2,02; p=0,030) y el índice total (63,97 ±4,22 vs. 59,74 ±5,53;
p=0,001). Los juveniles no mostraron una reducción del rendimiento de manera significativa. Entre ambos
grupos, en la evaluación con fatiga encontramos diferencias significativas en el tiempo de ej
(EN)The aim of the study was to verify the effect that fatigue induced by RSA has on performance of players, on decision making and on execution time of technical-tactical actions and to verify if there are differences between sub-18 and sub-16 categories. In total, 31 youth soccer players participated, 15 sub-18 players (16.87 ±0.64 years) and 16 sub-16 players (15.25 ±0.45 years). The performance of technical- tactical actions was evaluated without fatigue and with fatigue with the Stroop Task Football Test (STFT). To induce fatigue, an RSA protocol was performed between the two measurements. The sub-16's performance decreased significantly in execution time (57.67 ±3.79 vs. 60.76 ±4.59; p=0.006), decision making (61.25 ±1.39 vs. 60 .13 ±2.02; p=0.030) and the total index (63.97 ±4.22 vs. 59.74 ±5.53; p=0.001). Sub-18 players did not show a significant reduction in performance. Between both groups, in the evaluation with fatigue we found significant differences in the execution time (57.06 ±3.15 vs. 60.76 ±4.59; p=0.015) and in the total index (64.40 ±5 .54 vs. 59.74 ±5.53; In conclusion, sub-16 present a reduction in performance in technical-tactical actions when they are fatigued, while sub-18 do not present significant differences. However, the reduction in performance cannot be associated only with physical fatigue parameters.
