Cardiovascular System Adaptations Quiz

What is the primary focus of the cardiovascular system lesson?

• Acute exercise adaptations

• Dietary impacts on the heart

• Genetic factors in heart health

• Chronic adaptations to exercise

What happens to the left ventricle of the heart during cardiac hypertrophy?

• It shrinks

• It thickens

• It remains the same

• It becomes thinner

How does training affect stroke volume compared to untrained individuals?

• It has no effect

• It decreases stroke volume

• It only affects stroke volume during rest

• It increases stroke volume

What is capillarization and where does it occur?

• Increase in blood pressure, occurring in the arteries

• Increase in muscle size, occurring in the heart

• Decrease in blood vessels, occurring in the lungs

• Increase in capillary density, occurring in muscles and alveoli

What is the benefit of increased capillary density in muscles?

• Decreased muscle strength

• Reduced blood flow

• Improved oxygen supply and metabolism

• Increased muscle fatigue

How does aerobic training affect resting blood pressure?

• Has no effect

• Only affects it during exercise

• Increases it significantly

• Reduces it

What is heart rate recovery time?

• Time taken for heart rate to increase during exercise

• Time taken for heart rate to return to resting rate after exercise

• Time taken for heart rate to stabilize during rest

• Time taken for heart rate to decrease during sleep

What happens to blood volume as a result of long-term exercise?

• It fluctuates randomly

• It increases

• It remains unchanged

• It decreases

What role does the hormone EPO play in blood volume changes?

• It decreases red blood cell production

• It increases red blood cell production

• It has no effect on blood cells

• It reduces blood plasma

What is the effect of resistance training on blood pressure compared to aerobic training?

• No effect on blood pressure

• Equally effective

• Less effective in reducing blood pressure

• More effective in reducing blood pressure
