During a clinical study on the effects of exercise: Which measurement is likely to decrease?

Exercise Effects on Men's Health

During a clinical study examining the effects of exercise, men between the ages of 20 and 30 years are evaluated during a 15-minute session on a treadmill. The average pulse for the last 2 minutes of the session is 175/min. During the last minute of exercise, various measurements are taken.

Compared with the measurement before the session, which of the following is most likely to be decreased?
A. Oxygen consumption
B. Systolic blood pressure
C. Pulse pressure
D. Stroke volume
E. Heart rate
F. Cardiac output
G. Total peripheral resistance

Final answer:

During a clinical study examining the effects of exercise, the most likely measurement to be decreased compared to the measurement before the session is systolic blood pressure.

Explanation:

The most likely measurement to be decreased compared with the measurement before the session is Systolic blood pressure.

During exercise, the heart rate increases, which leads to an increase in stroke volume and cardiac output. This increased cardiac output causes an increase in systolic blood pressure. However, in this case, the average pulse for the last 2 minutes of the session is 175/min, which is higher than the resting systolic blood pressure. Therefore, it is most likely that systolic blood pressure would be decreased compared to the measurement before the session.
