PLEASE BE AWARE OF SUBJECT 1, SUBJECT 2, ABSOLUTE TERMS AND RELATIVE TERMS. THANK YOU!
The charts shown above depict VO2 vs. time for both subjects during the 20-minute period that includes the 10-minute bout of cycling at 600 kgm/min.
The chart depicting Subject 1's VO2 vs. time at 600 kgm/min is divided into 5 areas; A,B,C,D and E.
Which area represents steady-state exercise VO2?
Which area represents the period of EPOC?
Which area represents the period of oxygen deficit?
Which area represents pre-exercise VO2?
Which area represents return to resting VO2 after exercise?
2. What is the approximate steady-state VO2 of Subject 1 while cycling at 600 kgm/min expressed in absolute terms?
3. What is the approximate steady-state VO2 of Subject 2 while cycling at 600 kgm/min expressed in absolute terms?
4. What is the approximate steady-state VO2 of Subject 1 while cycling at 600 kgm/min expressed in relative terms?
5. What is the approximate steady-state VO2 of Subject 2 while cycling at 600 kgm/min expressed in relative terms?
6. Approximately how long did the period of EPOC last for Subject 1?
7. Approximately how long did it take for Subject 1 to reach steady-state VO2 after the onset of exercise?
8. Was the relative work rate during this bout greater for Subject 1 or Subject 2?

Which area represents steady-state exercise VO2?
At steady-state during excercise, the VO2 doesnot change.
ANSWER: C
Which area represents the period of EPOC?
Excess Post-excercise O2 consumption denotes the VO2 that occurs between steady-state and the resting VO2 after excercise.
ANSWER: D
Which area represents the period of oxygen deficit?
O2 deficit denotes the VO2 that occurs between resting VO2 before excercise and steady-state.
ANSWER: B
Which area represents pre-exercise VO2?
VO2 before O2 deficit is known as Pre-excercise VO2.
Which area represents return to resting VO2 after exercise?
VO2 after EPOC is known as resting VO2 after excercise.
