I don't have any reference ranges for you, but in my experience, based
on a student project in the lab, you can easily reduce the blood pH
in a healthy individual to 7.05 by exercise. However, it returns to
7.40 as the person recovers - and that is what distinguishes them
from someone with an acid-base disturbance.
