Question

which of the following is not a benefit of cardiorespiratory fitness?
a. more blood is pumped through the body.
b. the risk of cardiovascular disease is decreased.
c. longer durations of large muscle exercises are possible.
d. the efficiency of the respiratory system increases.

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

To determine the answer, we analyze each option:

• Option A: Cardiorespiratory fitness improves heart function, but "more blood pumped" isn't a direct benefit (efficient pumping, not just more volume, is key).
• Option B: Improved cardiorespiratory fitness does decrease cardiovascular disease risk.
• Option C: Better fitness allows longer large - muscle exercise durations.
• Option D: The respiratory system's efficiency increases with cardiorespiratory fitness.

So, A is not a benefit.

Answer:

A. More blood is pumped through the body.
