NETA Cardiovascular Training 2 — Questions and Answers
Question 1: What does VO2 max represent in the context of cardiovascular fitness?
- Maximum heart rate during exercise
- Maximum volume of oxygen consumed during intense aerobic exercise (Correct answer)
- Blood lactate concentration at peak effort
- Resting metabolic rate
Correct answer: Maximum volume of oxygen consumed during intense aerobic exercise
VO2 max represents the maximum volume of oxygen the body can consume and utilize during intense aerobic exercise and is considered the gold standard of cardiovascular fitness.
Question 2: In trained individuals, the anaerobic (lactate) threshold typically occurs at approximately what percentage of VO2 max?
- 40–50%
- 55–65%
- 70–80% (Correct answer)
- 90–95%
Correct answer: 70–80%
Trained individuals can sustain higher intensities before significant lactate accumulation, with the anaerobic threshold typically occurring at 70–80% of VO2 max.
Question 3: In the FITT principle for cardiovascular programming, what does the letter 'T' (the second T) represent?
- Tempo
- Training load
- Type of exercise (Correct answer)
- Threshold
Correct answer: Type of exercise
In the FITT principle, the second 'T' stands for Type of exercise, referring to the mode of cardiovascular activity selected (e.g., running, cycling, swimming).
Question 4: Steady-state cardio is best described as exercise performed at:
- Varying intensities throughout the session
- Maximum effort for a short duration
- A consistent, moderate intensity for an extended period (Correct answer)
- Alternating high and low intensities
Correct answer: A consistent, moderate intensity for an extended period
Steady-state cardio maintains a consistent, moderate intensity throughout the entire exercise session, keeping the heart rate relatively stable.
Question 5: Which physiological adaptation is most associated with long-term aerobic training?
- Decreased stroke volume
- Increased resting heart rate
- Increased cardiac output (Correct answer)
- Decreased mitochondrial density in muscle cells
Correct answer: Increased cardiac output
Long-term aerobic training increases cardiac output by improving stroke volume — the heart pumps more blood per beat, becoming a more efficient pump at rest and during exercise.
Question 6: Fartlek training is best described as:
- Fixed-interval high-intensity work with precise rest periods
- Unstructured continuous training with spontaneous intensity changes (Correct answer)
- Pyramid interval sets with progressively longer durations
- Long slow distance runs only
Correct answer: Unstructured continuous training with spontaneous intensity changes
Fartlek, a Swedish term meaning 'speed play,' is an unstructured form of cardiorespiratory training that involves spontaneous changes in intensity during a continuous workout.
Question 7: The 'talk test' is a practical field method for estimating which training intensity?
- Maximum effort approaching VO2 max
- Anaerobic threshold intensity
- Moderate aerobic intensity (Correct answer)
- Very light warm-up intensity only
Correct answer: Moderate aerobic intensity
The talk test estimates moderate aerobic intensity — if a client can speak comfortably in short sentences but cannot sing, they are likely at a moderate intensity level.
