The importance of visuomotor reactions in sports is inevitable; however, its assessment using computer-based tests raises the question, if results are transferable to sport-specific situations. Since computer-based simple reaction tests are widely used by sport scientists and practioners, this study examined their relation to sport-specific visuomotor reaction speed and performance. Seventeen international young elite table tennis players performed a simple visuomotor reaction test in response to stimuli presented on a computer screen (laboratory experiment) as well as table tennis balls played by a ball robot (sport-specific experiment). A sport-specific cued choice reaction task served as a control condition. The visuomotor reaction time (VMRT) was determined for all tasks. In addition, neurophysiological correlates of visual perception/processing speed (N2/N2-r) were measured in the laboratory experiment. The VMRT and neurophysiological parameters measured in the laboratory experiment predicted the sport-specific reaction speed (VMRT: r = 0.62; N2: r = 0.51; N2-r: r = -0.47) as well as sport-specific visuomotor performance reflected by the number of successfully hit balls (VMRT: r = -0.68; N2: r = -0.65; N2-r: r = 0.50). This did not apply to the choice reaction task. This study suggests computer-based behavioural and neurophysiological indices of visuomotor reaction time are directly related to the sport-specific visuomotor speed and performance in a more ecologically valid setting.
