Efecto de un programa de entrenamiento interválico intensivo corto en futbolistas juveniles

Abstract

Physical preparation in football is a fundamental pillar to optimize sports performance. The inherent logic of this discipline requires repeated sprint sequences with incomplete recoveries, generating fatigue in the players; for this reason it is essential to have an excellent ability to repeat short and maximum stimuli to achieve the desired results in official competitions. The purpose of this work is to analyze the effect of a short intensity interval training program on the performance of the repeat sprint ability (RSA) in 15 youth male soccer players (U-16). Two evaluations were carried out: an initial or pre-program and a final or post-intervention of the RSA, based on the test RCA Aziz et al. (2000), using the RACES TEST® device from Chronojump®. A training program with a duration of 12 weeks was developed, divided into three stages of four weeks each: Accumulation, transformation and realization. The results showed very significant changes statistically (p£0.05) in all test parameters with the T test of related samples, obtaining the following values: RSA Mean 6,28 s to 5,98 s; RSA Best 5,78 s to 5,69 s; RSA Worse 6,76 s to 6,31 s; RSA Ideal 46,29 s to 45,57 s; RSA Total 50,26 s to 47,83 s and the Fatigue Index 8,58 % to 5,11 %. These values corroborate that short intensive interval training improves the ability to repeat sprints, therefore performance. In addition, it is a simple and replicable program for all formative categories in soccer
