INTRODUCTION Longitudinal validity (or external responsiveness) indicates the ability of a test to reflect changes in the reference criterion. The Yo-Yo Intermittent Recovery Test Level 1 (YO1) is the most valid soccer endurance test; its validity has been showed by its correlations with high-intensity running (HIR) during the match, also it discriminates between competitive levels and playing positions(1). To our knowledge the longitudinal validity of YO1 has been assessed only in referees. A sub-maximal version of YO1 (YO1sub), ending at the 6thmin., has been proposed for some “special” population such as injured players during rehabilitation. The aim of this study was to examine the longitudinal validity of YO1 and YO1sub in soccer playe...
