The highest level of exercise that can be performed without causing a significant change in blood pH is called the ________.
A) Hering-Breuer reflex
B) aerobic threshold
C) anaerobic threshold
D) lactate tolerance level

Question

Quizplus · Accepted Answer

The anaerobic threshold refers to the point during exercise at which muscles start to produce lactic acid at a faster rate than it can be removed, leading to a significant change in blood pH if exceeded. This threshold marks the highest level of exercise intensity that can be sustained without causing a significant change in blood pH, as it indicates the transition from aerobic metabolism to anaerobic metabolism.
