Reliability of Scores Computed by a Commercial Virtual Reality System and Association with Indices of Cognitive Performance in Male Elite Rugby Players

Abstract

Purpose: To examine the reliability of scores calculated from virtual reality (VR) games and their association with inhibitory control and cognitive flexibility in young elite rugby players. Methods: Following a familiarization session, seventeen rugby union players completed a session of a modified Stroop test and two sessions of three VR games consisting of (1) memorizing moving targets (Tracker Master); (2) selecting moving targets while avoiding pitfalls (Beat Master—Never Stop); and (3) selecting moving targets with an increasing frequency of appearance (Beat Master—Turbo). Results: The reliability of Beat Master—Never Stop was poor to moderate (0.41 Beat Master—Turbo (0.77 Tracker Master, reliability was considered as low to moderate (0.22 Tracker Master and Stroop flexibility scores (−0.55 Beat Master—Never Stop scores and the Stroop inhibition score (0.52 Beat Master—Never Stop and Tracker Master games should be preferred for monitoring training load, provided at least two familiarization sessions precede them.
