Abstract

Venous acid-base balance and electrolyte concentration during step-graded and exhausting exercise with a two-minute steady-state has been studied in a group of non-trained young men.The results showed a significant decrease in pH, pCO2 and bicarbonate and a significant increase in lactate, potassium, inorganic phosphate and proteins during the exercise.The supervening acidosis had a large anion gap that was of proportion with the increase in lactate values.We suggest that the total sum of other anions such as proteins, phosphate, pyruvate, citrate, free fatty acids and aminoacids, as well as sodium-hydrogen exchange could account for this acidosis.
