Purpose. The aim of the study was to evaluate the reliability of the 8-s Skipping with Hand clapping (8-s SHc) test performed by kindergarteners. Methods. The study involved 60 girls and 57 boys (mean age: 67.80 ± 9.00 and 71.76 ± 6.43 months, respectively). The reliability of the 8-s SHc test was determined on the basis of the calculated values of correlation coefficients between the numbers of claps in 10 successive test trials. The ‘training trend’ hypothesis was verified by the Friedman test as well as conover-Iman’s post-hoc test, which was additionally used to identify the trials of the 8-s SHc test that differed significantly in the number of claps. Results. The values of correlation coefficients between the numbers of claps in 10 successive trials of the 8-s SHc test were within the range from acceptable reliability (0.80–0.90) to perfect reliability (0.95–0.99) in both girls and boys. Statistically significant differences between the numbers of claps in successive trials point to the presence of a ‘training trend.’ Those differences were observed up to the 3 trial in boys and up to the 5 trial in girls. Conclusions. The 8-s SHc test can be reliably used to assess speed abilities among kindergarteners. The ‘training trend’ should be eliminated before the test is used to evaluate the speed abilities of preschool children. A minimum number of repetitions (19 in girls and 15 in boys) have to be performed in advance for the final test to deliver reliable results.
