Question

select the correct answer.
what does cardiorespiratory fitness measure?
a. a persons ability to transport oxygen through the body
b. a persons ability to transport blood through the body
c. a persons ability to recover from physical activities
d. a persons ability to complete physical activities

Explanation:

Cardiorespiratory fitness is related to the heart (cardio) and lungs (respiratory). The main function of the cardio - respiratory system is to transport oxygen (from the lungs, via the heart and blood) to the body's tissues. While blood transport (B) is part of it, the key is oxygen transport. Recovery (C) and completing physical activities (D) are outcomes influenced by cardiorespiratory fitness but do not directly measure what it is. So, it measures the ability to transport oxygen (A).

Answer:

A. a person's ability to transport oxygen through the body
