NFPT Cardiovascular Training and Conditioning 1

Question 1

Which energy system is primarily used during low-intensity, long-duration aerobic exercise?

Accepted Answer

Aerobic oxidative system

Answer

The aerobic oxidative system uses oxygen to produce ATP and is dominant during sustained, low-to-moderate intensity exercise lasting several minutes or longer.

Question 2

Which formula is most commonly used to estimate maximum heart rate (MHR)?

Accepted Answer

220 - age

Answer

The most widely used estimate for maximum heart rate is 220 minus the client's age, although newer formulas like 207 - (0.7 × age) may be more accurate.

Question 3

What does 'steady-state exercise' mean in the context of cardiovascular training?

Accepted Answer

Exercise where oxygen supply meets the working muscles' oxygen demand

Answer

Steady-state exercise is reached when oxygen delivery and consumption are balanced, allowing the client to sustain activity without accumulating significant lactic acid.

Question 4

The Karvonen formula for calculating target heart rate incorporates which two variables?

Accepted Answer

Resting heart rate and maximum heart rate

Answer

The Karvonen (heart rate reserve) formula uses the difference between maximum heart rate and resting heart rate, then adds resting heart rate back after applying the desired intensity percentage.

Question 5

Which type of cardiovascular training involves alternating between high-intensity efforts and recovery periods?

Accepted Answer

Interval training

Answer

Interval training systematically alternates between higher-intensity work bouts and lower-intensity recovery periods to improve cardiovascular capacity and metabolic conditioning.
