ABSTRACT
Therefore, it is important that the players develop their ability to perform intense intermittent exercise and have this ability evaluated at different stages during the competitive season. Due to its specificity and practicality, the Yo-Yo intermittent recovery test 2 (YYIR2) has been extensively used in soccer to assess players’ abilities to perform repeated high-intensity exercise. Studies have shown its sensitivity in discriminating players’ performances at various competitive levels, between different playing positions, and after periods of different types of training.
