  1. What is the primary fuel source during moderate-intensity aerobic exercise lasting 30–60 minutes?

    Answer: A mix of carbohydrates and fats

    During moderate-intensity sustained exercise the body utilizes a blend of carbohydrates and fats, with the ratio shifting based on intensity and duration.

  2. Which principle describes the body's adaptation to progressively increasing exercise demands?

    Answer: Progressive overload

    The principle of progressive overload states that the body must be exposed to gradually increasing stress to continue making fitness adaptations.

  3. What is the primary cardiovascular adaptation seen after weeks of consistent aerobic training?

    Answer: Decreased resting heart rate (bradycardia)

    Chronic aerobic training increases stroke volume, allowing the heart to pump more blood per beat, which results in a lower resting heart rate.

  4. Which term describes the point during increasing exercise intensity at which lactate begins to accumulate faster than it is cleared?

    Answer: Anaerobic threshold (lactate threshold)

    The anaerobic threshold (lactate threshold) is the exercise intensity above which lactate accumulates in the blood faster than it can be removed.

  5. How does heat stress affect exercise performance in a group fitness class?

    Answer: It increases cardiovascular strain and reduces endurance capacity

    Heat stress forces the cardiovascular system to divert blood to the skin for cooling, reducing blood flow to muscles and increasing heart rate at the same workload.

  6. What is the recommended method for estimating exercise intensity when heart rate monitors are unavailable?

    Answer: Rating of Perceived Exertion (RPE)

    The Rating of Perceived Exertion (RPE) scale allows participants to self-report exercise intensity, correlating well with physiological measures like heart rate and VO2.
