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

    Answer: Aerobic oxidative system

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

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

    Answer: 220 - age

    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.

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

    Answer: Exercise where oxygen supply meets the working muscles' oxygen demand

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

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

    Answer: Resting heart rate and maximum heart rate

    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.

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

    Answer: Interval training

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

  6. What does VO2max represent in cardiovascular fitness?

    Answer: The maximum rate at which the body can consume oxygen during exercise

    VO2max is the gold standard measure of cardiorespiratory fitness, reflecting the maximum volume of oxygen the body can utilize per minute during intense exercise.

  7. Which heart rate zone (as a percentage of MHR) is commonly referred to as the 'fat-burning zone'?

    Answer: 60–70% MHR

    The 60–70% MHR zone relies more heavily on fat as a fuel source due to lower intensity, though total caloric burn is higher at greater intensities.
