  1. Which acute cardiorespiratory response would you MOST expect during the transition from rest to moderate-intensity exercise?

    Answer: Increased cardiac output

    Cardiac output rises during exercise primarily through increases in both heart rate and stroke volume to meet elevated oxygen demands.

  2. An older adult client (age 68) wants to use the age-predicted HRmax formula. Which equation provides the MOST accurate estimate for older adults?

    Answer: 208 − (0.7 × age)

    The Tanaka formula (208 − 0.7 × age) is more accurate than 220 − age, especially for older adults, as it avoids overestimating maximal HR.

  3. During steady-state cardio, a client's breathing becomes labored and she can no longer hold a conversation. Which threshold has MOST likely been crossed?

    Answer: VT2

    VT2 (second ventilatory threshold) marks the point where ventilation increases sharply and sustained conversation becomes impossible.

  4. Which type of cardiorespiratory program is MOST effective for burning the greatest total calories in a single session?

    Answer: Moderate-intensity continuous training (45–60 minutes)

    Longer duration moderate-intensity continuous sessions accumulate the greatest total caloric expenditure despite lower intensity per minute.

  5. A client performs cardio on a stationary bike. Their breathing rate increases significantly but they can still speak with some effort. This BEST reflects exercise intensity at which zone?

    Answer: Between VT1 and VT2 (Zone 2)

    Zone 2 training (between VT1 and VT2) produces elevated but manageable breathing; the client can speak but finds it effortful.

  6. Which principle of exercise programming states that gains made from cardiorespiratory training are lost when training stops?

    Answer: Reversibility

    The principle of reversibility (detraining) states that physiological adaptations regress when the training stimulus is removed.

  7. A client's resting heart rate is 65 bpm and estimated HRmax is 185 bpm. Using the Karvonen method, what is the target heart rate at 70% intensity?

    Answer: 149 bpm

    HRR = 185−65 = 120; 70% of 120 = 84; 84 + 65 = 149 bpm using the Karvonen formula.
