Response of various blood measures to high-intensity interval training (HIIT) with ingestion of sodium bicarbonate (BICARB) or a placebo (PLAC). Blood pH (A) bicarbonate (B) concentrations at five time points: before ingestion (PRE ING), after ingestion, after HIIT, 2 h after recovery, and 3 h after recovery. Blood pH (A), bicarbonate concentration (B), and lactate concentration (C) at five time points. *Main effect for time compared with PRE ING (P < 0.01). †Significant difference between BICARB and PLAC at the time point designated (P < 0.01). Main effect for treatment was observed in blood pH, bicarbonate concentration, and lactate (P < 0.01).
