Revision of two test items of the dutch motor skills assessment measuring ball control in young table tennis players: a reproducibility and validity study

Can Perceptuo-Motor Skills Assessment Outcomes in Young Table Tennis Players (7–11 years) Predict Future Competition Participation and Performance? An Observational Prospective Study

“…Univariable logistic regression analyses to show whether the assessment’s results predicted competition participation within the measurement period of this study demonstrated no significant predictors; all regression coefficients show p >0.05 with the odds ratio 95% confidence intervals including 0 (n = 48; Table 2 ). Moreover, the differences between the means of the non-competition (n = 9) and competition players (n = 39) at the individual test items ( Table 2 ) were generally smaller than the standard error of the measurements of the items found in the previous studies focusing on reproducibility [ 35 , 36 ]. Only the covariate training experience presented to be a significant predictor for future competition participation ( p = 0.012).…”

“…The perceptuo-motor skills assessment of the Netherlands Table Tennis Association consists of eight test items [ 35 , 36 ]. The standardization of the test items is captured in protocols, which includes a detailed description of materials, set-up, assignment, demonstration, training phase, testing phase and registering test scores ( S1 File ) [ 27 , 34 – 36 ]. ‘Sprint’ included a pyramid-shape circuit in which players need to gather and return five table tennis balls one by one as fast as possible from five different baskets starting at the basis of the pyramid-shaped circuit.…”

“…As expected, there were moderate but significant relationships between the perceptuo-motor skills assessment’s total score and the national ranking for boys and girls (6–10 years) at the moment of testing [ 35 ]. A revision of the test items ‘aiming at target’ and ‘ball skills’ ensured reproducible test scores, which also discriminated between high and low performers in young table tennis players [ 36 ]. Consequently, both revised test items replaced the original test items in the perceptuo-motor skills assessment.…”

“…From this perspective, the Netherlands Table Tennis Association proposed a perceptuo-motor skills assessment [ 34 ]. This assessment intends to measure the potential of a young player (6–12 years) with regard to the perceptuo-motor domain, by assessing underlying perceptuo-motor skills for table tennis without using already trained authentic table tennis tasks [ 35 , 36 ]. Assessing these underlying perceptuo-motor skills is suggested to represent a player’s future potential better than specific sport skills themselves, which depend on exposure to the sport itself, table tennis in this case [ 5 – 7 , 27 , 35 , 37 ].…”

“…Assessing these underlying perceptuo-motor skills is suggested to represent a player’s future potential better than specific sport skills themselves, which depend on exposure to the sport itself, table tennis in this case [ 5 – 7 , 27 , 35 , 37 ]. At this moment, the reproducibility of all test items is confirmed and the internal consistency and validity have good prospects [ 35 , 36 ]. Still, an evaluation of the perceptuo-motor skills assessment concerning its predictive validity is essential for talent development purposes [ 5 , 6 ].…”
