Yes, the blood become more acidic during the heavy exercise because of the production of CO2 in the body.
Acidic Blood- Exercise that is vigorous will drop blood pH and increase blood acidity. This happens because during intense activity, muscle cells are compelled to engage in anaerobic respiration. Lactic acid is a byproduct of this kind of cellular respiration. The blood's pH level will decrease in the influence of this acid.
