What happens when, during exercise, the oxygen needs of the peripheral tissues increase greatly?
After light exercise, the oxygen consumed in recovery is approximately equal to the oxygen deficit, which is the amount of additional oxygen that would have been consumed had oxygen consumption reached steady state immediately. How is the oxygen consumed in recovery used?
The oxygen consumed after strenuous exercise stops is significantly greater than the oxygen deficit and is termed excess postexercise oxygen consumption (EPOC). Why is so much more oxygen required after intense exercise?
