As exercise intensity increases ____.
A) relative fat oxidation increases
B) absolute fat oxidation decreases
C) relative fat oxidation increases to a point, then decreases
D) absolute fat oxidation increases to a point, then decreases

Question

Quizplus · Accepted Answer

As exercise intensity increases, absolute fat oxidation increases to a point, then decreases. This occurs because as exercise intensity increases, the body relies more on carbohydrate metabolism for energy production, leading to a decrease in the proportion of energy derived from fat oxidation. Eventually, the intensity becomes too high for the body to efficiently utilize fat as an energy source, resulting in a decrease in absolute fat oxidation.
