1. What is cardiovascular exercise primarily designed to improve?

A. Flexibility only

B. Muscle size only

C. The ability of the heart, lungs, circulation and muscles to work together efficiently

D. Bone density only

E. Balance only

2. Why is cardiorespiratory fitness considered such an important measure of health?

A. It only determines how fast someone can run

B. It is mainly important for competitive athletes

C. It tells us how flexible someone is

D. Higher cardiorespiratory fitness is strongly associated with lower risks of cardiovascular disease and premature death

E. It guarantees that someone will never develop heart disease

3. Which of the following is a major benefit of regular cardiovascular exercise?

A. It only burns calories while you are exercising

B. It removes the need to monitor blood pressure

C. It can improve blood pressure, vascular function, blood sugar control and cardiovascular fitness

D. It prevents every type of chronic illness

E. It completely replaces the need for resistance training

4. How can cardiovascular exercise help with blood sugar control?

A. It prevents muscles from using glucose

B. It stops the body from producing insulin

C. It only improves blood sugar if substantial weight loss occurs

D. Working muscles use glucose, and regular exercise can improve insulin sensitivity

E. Cardiovascular exercise has no meaningful effect on metabolic health

5. What does having greater "physiological reserve" mean?

A. You can stop exercising once you become fit

B. Your maximum physical capacity becomes unlimited

C. You should avoid activities that increase your heart rate

D. Everyday activities require a smaller percentage of your maximum physical capacity

E. Your body stores additional oxygen for future exercise sessions

6. What does newer research into short bursts of vigorous activity suggest?

A. Cardiovascular exercise only works when performed continuously for at least one hour

B. A single short burst of exercise each week is enough for optimal health

C. Structured cardiovascular exercise is no longer necessary

D. Short bursts of harder activity during everyday life may also contribute meaningful health benefits

E. Only low-intensity exercise is beneficial for cardiovascular health

7. How much cardiovascular exercise is generally recommended for adults each week?

A. Exactly 30 minutes of exercise per week

B. At least 10 hours of vigorous exercise per week

C. Cardiovascular exercise is unnecessary if you perform strength training

D. Approximately 150–300 minutes of moderate-intensity activity, or 75–150 minutes of vigorous activity, or an equivalent combination

E. Everyone must perform exactly 300 minutes regardless of their health or fitness level

8. Why shouldn't cardiovascular exercise replace resistance training?

A. Cardiovascular exercise provides no health benefits

B. Resistance training improves cardiovascular fitness better in every situation

C. Cardiovascular exercise should only be used as a warm-up

D. Cardiovascular and resistance training produce different but complementary adaptations, so a complete program generally benefits from both

E. Resistance training is only required by athletes

9. What is the best approach for someone beginning cardiovascular exercise after a long period of inactivity?

A. Immediately begin maximal-intensity interval training

B. Avoid cardiovascular exercise until their fitness improves naturally

C. Perform exactly the same exercise intensity permanently

D. Start at an appropriate level and progressively increase duration and intensity as the body adapts

E. Only perform cardiovascular exercise if weight loss is the primary goal

10. What is the main message of this module?

A. Cardiovascular exercise is primarily useful for losing weight

B. Cardiovascular exercise is only necessary for people with heart disease

C. Strength training makes cardiovascular exercise unnecessary

D. Cardiovascular fitness only matters when we are young

E. Regular, progressively appropriate cardiovascular exercise is an essential part of protecting health, maintaining physical capacity and supporting a longer, healthier and more independent life
