Exploring Cardiac Output: The Impact of Heart Rate and Stroke Volume

What is the basic formula for calculating cardiac output?

• Cardiac output = Heart rate + Stroke volume

• Cardiac output = Heart rate / Stroke volume

• Cardiac output = Heart rate * Stroke volume

• Cardiac output = Heart rate - Stroke volume

What typical resting heart rate is expected for a sedentary individual?

• 110 beats per minute

• 90 beats per minute

• 70 beats per minute

• 50 beats per minute

What is the expected stroke volume at rest for an endurance athlete?

• 120 milliliters per beat

• 80 milliliters per beat

• 100 milliliters per beat

• 70 milliliters per beat

During exercise, what peak stroke volume might a trained athlete achieve?

• 130 milliliters

• 150 milliliters

• 100 milliliters

• 80 milliliters

What factor does not adapt, whether an athlete is trained or untrained?

• Max heart rate

• Stroke volume

• Cardiac output

• Heart rate

What is the maximum cardiac output a sedentary individual can achieve during exercise?

• 25 liters per minute

• 20 liters per minute

• 15 liters per minute

• 10 liters per minute

How much blood per minute can an endurance trained athlete deliver during maximum exercise?

• 15 liters

• 20 liters

• 30 liters

• 25.5 liters

By how much can an endurance trained athlete increase their blood delivery during work compared to rest?

• Two to three times

• Three to four times

• Five to six times

• Four to five times

Approximately how much lower is the cardiac output in females compared to males?

• 30 percent lower

• 25 percent lower

• 15 percent lower

• 10 percent lower

What is a significant factor contributing to the difference in cardiac output between genders?

• Blood volume

• Left ventricle chamber size

• Stroke volume variability

• Heart rate variability
