Statistical analysis The variables were expressed as mean and standard deviation. Data were checked for normality (Kolmogorov-Smirnov), homogeneity (Levene), and sphericity (Mauchly) assumptions. The variables were analyzed using a two-factor mixed ANOVA considering the effects between categories (sub-13 and 17) and within the experimental protocols (TS, TDM, TDC1, and 2). Bonferroni post hoc tests were performed when significant differences were found between and/or within categories and experimental protocols. Standardized effect sizes were presented as partial eta squared (ηp²) and were classified as small (0.04), moderate (0.25), or large (0.64) (Ferguson, 2009). For all analyses, the significance level adopted was p < 0.05. The Statistical Package for Social Science (SPSS) software for Windows®, version 20, was used for all analyses.
