Q

Which of the following is false concerning blood pressure response during moderately steady state exercise in a healthy individual?

a. compared to leg, arm cycle O2 at same O2 uptake is generally performed with lower systolic blood pressure
b. Magnitude of ones BP linked to cardiac output and total peripheral resistance (True?)
c. Systolic blood pressure increases rapidly, but then levels off between 140 and 160 mmHg
d. At the same percentage of peak oxygen consumption, blood pressure is higher during dynamic arm exercise compared to dynamic leg exercise.

A

Answer: a

d. pg. 151: At the same percentage of peak oxygen consumption, blood pressure is higher during dynamic arm exercise compared to dynamic leg exercise. Because there is greater resistance to blood flow with arm exercise because of smaller muscle size and vasculature.
