PBC
All data are presented as mean ± standard deviation. Assumptions of statistical tests such as normal distribution (Shapiro-Wilk test with visual inspection) and sphericity of data (Mauchly’s test) were checked as appropriate. Greenhouse-Geisser correction to the degrees of freedom was applied when violation to sphericity was present. Two-way repeated measured ANOVA was used to determine the treatment factor (2 levels, PBC and Control), time factor (3 levels, at 1000 m, 2000 m, 3000 m splits), and interaction on RPE during the 3000-m tests. Significant main effects and interactions were interpreted through pairwise comparisons with Bonferroni correction. Paired sample t tests were used to compare the other variables between the PBC and control conditions. Significance was set at 0.05 (two-tailed) for all analyses. Effect sizes for repeated measure ANOVA are reported as partial eta squared (η
