In a workout your muscle cells produce lactate, yet you maintain a constant blood ph because the body contains chemicals called buffers that resist changes in pH.
Exercise causes the body to breathe more quickly, which helps to offset the pH-lowering effects of exercise by expelling CO2, which is a part of the main pH buffer in the blood.
Respiratory acidosis is an acidosis that happens when the lungs are unable to expel CO2 as quickly as it is created.
Exercise has a variety of immediate and long-term consequences that must be tolerated by the body for it to be effective.
Exercise in particular causes chemical changes in the blood that, if not reversed by other physiological processes, cause the pH of the blood to decrease.
