ACSM-EP Cardiovascular Physiology

Question 1

A client has a resting blood pressure of 120/80 mmHg. What is the approximate mean arterial pressure (MAP)?

Accepted Answer

93 mmHg

Answer

MAP = DBP + 1/3(SBP - DBP) = 80 + 13 = about 93 mmHg.

Question 2

During peak exercise, cardiac output is 20 L/min and the arteriovenous oxygen difference is 15 mL O2 per 100 mL blood. According to the Fick equation, what is VO2?

Accepted Answer

3,000 mL/min

Answer

VO2 = Q x a-vO2 difference = 20 L/min x 150 mL O2/L = 3,000 mL/min.

Question 3

Which blood pressure response is normal during a graded treadmill exercise test in a healthy adult?

Accepted Answer

Systolic rises progressively while diastolic stays the same or changes slightly

Answer

Systolic BP rises progressively (about 10 mmHg per MET) while diastolic stays about the same or changes by 10 mmHg or less.

Question 4

During a cycling session, a client has a heart rate of 140 bpm and a systolic blood pressure of 160 mmHg. What is the rate-pressure product, and what does it estimate?

Accepted Answer

22,400; myocardial oxygen demand

Answer

RPP = HR x SBP = 140 x 160 = 22,400, an index of myocardial oxygen demand.

Question 5

After 12 weeks of endurance training, a client performs the same absolute submaximal workload as before. Which change is expected?

Accepted Answer

Lower heart rate and higher stroke volume

Answer

At the same submaximal workload, trained individuals have a lower heart rate and a higher stroke volume, with cardiac output about unchanged.
