pH value, sodium bicarbonate concentration (SBi) and base excess (BE) were conducted at rest (post ing) and two minutes post exercise (post ex). Data are presented as means ± SD: Significance was tested using one-factorial repeated measures analysis of variance (factor: condition; post-hoc: Scheffé test).
