ACE Cardiorespiratory Program Design 4

Question 1

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

Accepted Answer

Increased cardiac output

Answer

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

Question 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?

Accepted Answer

208 − (0.7 × age)

Answer

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

Question 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?

Accepted Answer

VT2

Answer

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

Question 4

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

Accepted Answer

Moderate-intensity continuous training (45–60 minutes)

Answer

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

Question 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?

Accepted Answer

Between VT1 and VT2 (Zone 2)

Answer

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