Exercise 10

Explain how endurance training improves acid-base balance during exercise.

Step 1 of 3

The pH of the blood is maintained near 7.4. Though the body can tolerate slight fluctuations in the pH, large variations can become fatal. The body has buffer systems of both pulmonary and renal origin that resist changes in pH. Along with those, the muscles have their intrinsic buffering capacity though the ability to buffer is very less. Endurance training program increases muscle buffering capacity.
