Question

A dramatic increase in what cardiovascular measurement is a risk factor during aerobic training?

A. Resting heart rate
B. Stroke volume
C. Blood pressure
D. Cardiac output

Answer 1

During aerobic training, there is a dramatic increase in cardiac output, which is the measurement of blood flow from the heart through the ventricles. This increase in cardiac output can be a risk factor due to the associated elevated blood pressure.

Step-by-step explanation:

During aerobic training, there is a dramatic increase in cardiac output. Cardiac output is the measurement of blood flow from the heart through the ventricles and is calculated by multiplying heart rate and stroke volume. As heart rate and stroke volume increase during aerobic training, so does cardiac output. This increase in cardiac output can pose a risk factor due to the elevation in blood pressure that occurs.
