Compared to low-intensity exercise,the excess post-exercise oxygen consumption is greater in high-intensity exercise because
A)heat production and body temperature is higher.
B)phosphocreatine levels in the muscle is depleted and more oxygen is required to resynthesize phosphocreatine during recovery.
C)blood epinephrine and norepinephrine levels are much higher.
D)all of the above answers are correct

Question

Quizplus · Accepted Answer

All of the mentioned factors contribute to the increased excess post-exercise oxygen consumption (EPOC) following high-intensity exercise. Higher heat production and body temperature, depletion of phosphocreatine levels requiring oxygen for resynthesis, and elevated blood epinephrine and norepinephrine levels all demand more oxygen during the recovery period, thus increasing EPOC.
