The study of metabolic processes that yield or consume energy is ____?

Bioenergetics

16

Factors that can affect a VO2max test include____?

All of the above

(Mode of test, economy of movement, genetics, sex)

17

In which situation would EPOC be the smallest?

Running at 60% VO2max for 30 minutes

(whatever the least % is for least amount of time)

(A. Potassium leaves the intracellular space
B. Cholinesterase may become hyperactive
C. pH drops below 6.9
D. Accumulation of H+ ions)

20

Aerobically trained athletes will have which type of response in their oxygen deficit?

Low O2 deficit, meaning a shorter time to steady state O2 consumption
