NFPT Cardiovascular Training and Conditioning 2 — Questions and Answers
Question 1: The 'talk test' is used by personal trainers to estimate which aspect of a client's workout?
- Muscular endurance capacity
- Exercise intensity (Correct answer)
- Flexibility level
- Body composition status
Correct answer: Exercise intensity
The talk test gauges exercise intensity by assessing whether a client can speak comfortably; difficulty speaking indicates anaerobic threshold has been approached.
Question 2: Which cardiovascular adaptation commonly occurs after several weeks of consistent aerobic training?
- Decreased stroke volume at rest
- Increased resting heart rate
- Decreased resting cardiac output
- Increased stroke volume (Correct answer)
Correct answer: Increased stroke volume
Regular aerobic training causes cardiac hypertrophy and improved contractility, resulting in a higher stroke volume, which allows the heart to pump more blood with each beat.
Question 3: In the FITT principle applied to cardiovascular exercise, which component refers to the duration of each session?
- Frequency
- Intensity
- Time (Correct answer)
- Type
Correct answer: Time
The 'T' for Time in the FITT principle refers to how long each exercise session lasts, typically measured in minutes for cardiovascular training.
Question 4: The original Borg Rating of Perceived Exertion (RPE) scale ranges from:
- 1 to 10
- 6 to 20 (Correct answer)
- 0 to 100
- 0 to 10
Correct answer: 6 to 20
The original Borg RPE scale runs from 6 to 20, with 6 representing rest and 20 representing maximal exertion; the numbers loosely correspond to heart rate when multiplied by 10.
Question 5: Cardiac output is calculated as:
- Heart rate × stroke volume (Correct answer)
- Heart rate × blood pressure
- Stroke volume × VO2max
- Heart rate × oxygen consumption
Correct answer: Heart rate × stroke volume
Cardiac output equals heart rate multiplied by stroke volume, representing the total volume of blood the heart pumps per minute.
Question 6: Which term best describes the ability of the heart, lungs, and circulatory system to deliver oxygen to working muscles over time?
- Muscular endurance
- Cardiorespiratory endurance (Correct answer)
- Anaerobic capacity
- Muscular power
Correct answer: Cardiorespiratory endurance
Cardiorespiratory endurance reflects the efficiency of the cardiovascular and respiratory systems working together to sustain aerobic activity over extended periods.
Question 7: HIIT (High-Intensity Interval Training) is primarily known for improving which physiological parameters?
- Resting blood pressure only
- Static flexibility
- VO2max and metabolic rate (Correct answer)
- Passive muscle strength
Correct answer: VO2max and metabolic rate
HIIT effectively raises VO2max and elevates post-exercise metabolic rate (EPOC), making it time-efficient for improving both aerobic capacity and caloric expenditure.
