The oxygen debt is generally higher following heavy exercise when compared with light exercise because heavy exercise
A) produces more lactic acid.
B) results in greater body heat gained, greater CP depleted, higher blood levels of epinephrine and norepinephrine, and greater depletion of blood and muscle oxygen stores.
C) results in a greater level of liver glycogen depletion.
D) is of shorter duration than light exercise.

Heavy exercise results in greater body heat gained, greater CP depleted, higher blood levels of epinephrine and norepinephrine, and greater depletion of blood and muscle oxygen stores, leading to a higher oxygen debt compared to light exercise. While heavy exercise does produce more lactic acid, this is not the main reason for the higher oxygen debt. The level of liver glycogen depletion is not significantly different between heavy and light exercise. The duration of the exercise is also not a determining factor in the oxygen debt.
