摘要：AbstractThe purpose of this study consists of analyzing the existing correlations between the simple reaction time (measures the speed of the nervous influx), the discrimination reaction time (measures the speed of the nervous influx combined with the identification time), the decision time (the necessary time needed for the mental operation of identification), vigilance and the sports performance of elite Romanian junior tennis players. The TR and VIGILANCE tests, included into the PSISELTEVA battery, developed by RQ Plus, evaluates the simple reaction time, the discrimination reaction time and vigilance. The subjects who took part in this study are 12 elite junior tennis players. Using the Spearman correlation there have been important relations highlighted between the decision time, vigilance and the sports performance, expressed through the ranking position (the official ranking system).
