1Data analyzed by one-way ANOVA with repeated measurements; effect size expressed as partial eta-squared (). 2Data analyzed by Friedman’s ANOVA and subsequent two-group comparisons by Wilcoxon signed-rank test; effect size expressed as Kendall’s Concordance Coefficient W. Abbreviations: BASE – baseline (no supplementation), HRmax – maximal heart rate, PCT – power carry threshold at 97%PP, PLA – after placebo treatment, PP – peak power, SB – after sodium bicarbonate supplementation, WAnT_1 – the Wingate anaerobic test performed before hockey-specific performance test, WAnT_2 – the Wingate anaerobic test performed after hockey-specific performance test
