Sažetak
The aim of this study was to determine the amount of correlation (common variance) between the MRSPTL (the raising of the torso from a lying position) test performed in 30 seconds and the same test performed in 60 seconds in 167 early school age pupils from the first to third grade, as well as exploring age and gender based differences. By analyzing the correlation between these tests, which were conducted in order to assess the relative repetitive strength of the torso in first- grade, second-grade and third-grade elementary school pupils, a statistically significant and extremely high correlation was established, both on the entire sample (Pearson r = 0.906), in first-grade pupils (Pearson r = 0.895), second-grade pupils (Pearson r = 0.948) and third-grade pupils (Pearson r = 0.887). This correlation does not depend on gender, and is high in both genders, being r = 0.905 among boys and r = 0.887 among girls. Since these two tests comprise more than 82 % (0.9062) of the common variability, it can be concluded that they share the intended object of measurement, i.e. that both tests estimate the relative repetitive strength of the torso in early school-age children. Using a post – hoc test based on the statistically significant differences, the results indicate that the 30- second test better differentiates the first- grade and second-grade elementary school pupils, while the 60-second test better differentiates the second-grade and third-grade elementary school pupils, which indicates they can be used in practice, for various purposes.
