¹Data analyzed by Wilcoxon signed-rank test; effect size expressed as rank correlation coefficient (r_c). ²Data analyzed by two-way ANOVA with repeated measurements; effect size expressed as partial eta-squared (${\eta }_p^2$). Abbreviations: HR_average – average heart rate, HR_max – maximal heart rate, PLA_-PRE – before placebo treatment, PLA_-POST – after placebo treatment, SB_-PRE – before sodium bicarbonate supplementation, SB_-POST – after sodium bicarbonate supplementation
