* Indicates that the one-way repeated measures ANOVA showed significant differences between groups before and after the intervention, p < 0.05; # indicates that there is a statistical difference between the HRW and PW groups at the same time, p < 0.05; HRW: hydrogen-rich water; PW: placebo water; HRPC: heart rate percent change.
