Question 1

The phosphocreatine (ATP-PC) energy system is the primary fuel source for activities lasting approximately how long?

Accepted Answer

0–10 seconds

Answer

The ATP-PC system provides immediate, high-intensity energy but is depleted within approximately 10 seconds of maximal effort.

Question 2

VO2 max is defined as which of the following?

Accepted Answer

The maximum rate of oxygen consumption during maximal incremental exercise

Answer

VO2 max is the highest rate at which the body can consume oxygen during maximal aerobic exercise, reflecting overall cardiorespiratory fitness.

Question 3

The glycolytic (anaerobic) energy system is the primary energy source for activities lasting approximately:

Accepted Answer

10 seconds to 2 minutes

Answer

The glycolytic system predominates during activities lasting approximately 10 seconds to 2 minutes, bridging the phosphagen and oxidative systems.

Question 4

During intense exercise approaching VO2 max, which fuel substrate provides the greatest contribution to muscle energy?

Accepted Answer

Muscle glycogen via anaerobic glycolysis

Answer

At exercise intensities near VO2 max, muscle glycogen is the predominant fuel because it can be rapidly broken down anaerobically via glycolysis.

Question 5

The Fick equation expresses VO2 as:

Accepted Answer

Cardiac output multiplied by the arteriovenous oxygen difference

Answer

The Fick equation states VO2 = Cardiac Output × a-vO2 difference, linking oxygen delivery via cardiac output to oxygen extraction by peripheral tissues.
