Sensitivity and Reliability of a Specific Test of Stroke Performance in Table Tennis

Abstract

Purpose:To develop a simple, reliable, and sensitive test to measure stroke performance (ball speed and accuracy) in table tennis.Methods:Fifty-two players were divided into 3 groups in accordance with their level: expert (EG), advanced (AG), and inexperienced (IG). The test consisted of 45 forehand shots where players were asked to reach 3 targets. The test was performed 2 times (separated by 8 min) during the first session (n = 52) to assess intrasession reliability. A second session (n = 28), at least 3 d later, was performed to test intersession reliability. Both speed and accuracy of the ball were measured to evaluate the absolute sensitivity and reliability of the specific test.Results:This study showed good reliability of the specific test for both ball speed and accuracy of EG and AG (ICC range .42–.96, CV range 2.0–9.0%). However, the reliability is low for IG. Ball speed and accuracy were greater in EG than in the other groups, and both variables were correlated with the level of the players.Conclusion:Results suggest that the specific test appears to be a simple and sensitive procedure to assess stroke performance in table tennis and that this test could be a relevant tool for coaches in table tennis.
