Análisis de la relación entre el Yo-Yo Test y el consumo máximo de oxígeno en jóvenes jugadores de fútbol. [Analysis of the relationship between Yo-Yo Test and maximum oxygen uptake in young football players].

Abstract

This work aimed to examine the validity of the Yo-Yo Endurance Test Level 1 to estimate the maximum oxygen uptake in football players. Participants were 15 male football players, ranging in age from 17 to 19 years old (M = 17,9; DT = 0,67), who developed a laboratory test until exhaustion and Yo-Yo Test Level 1. Results showed significant differences in the values directly and indirectly obtained, being the values lower in the oxygen uptake estimated with Yo-Yo Test. Furthermore, Yo-Yo Test performance was not related with maximum oxygen uptake relative to weight on laboratory, showing that Yo-Yo Endurance Test Level 1, through the equation described by Bangsbo, Iaia, and Krustrup (2008) is not a valid test to estimate maximum oxygen uptake in young football players.
