If you exercise with enough intensity that the blood pH is changed, you have exceeded the ________.

A) aerobic threshold
B) acidity point
C) base point
D) pH threshold
E) anaerobic threshold

Anaerobic Threshold

The point during intense exercise at which the body starts to produce energy through anaerobic metabolism, leading to the rapid accumulation of lactic acid in the muscles.

Aerobic Threshold

The intensity of exercise at which the body switches from anaerobic to aerobic metabolism, indicating improved endurance.

Blood Ph

The measure of the acidity or alkalinity of the blood, with a normal range typically between 7.35 and 7.45.
