Lactate concentrations were lower for the high-EST, high-CO2 treatment compared with the low-EST, low-CO2 treatment (Δ = 0.49 mmol/L), whereas lactate concentrations for other treatments were comparable. Potassium was lower for the low-EST, low-CO2 treatment compared with the normal-EST, high-CO2 treatment (Δ = 0.6 mmol/L) and high-EST, low-CO2
treatment (Δ = 0.5 mmol/L)
