The measurement of oxygen consumption during exercise can provide an estimate of metabolic rate.The rationale behind the use of oxygen consumption to estimate metabolic rate is:
A)that measurement of oxygen consumption provides a direct estimate of how much carbohydrate is used a fuel source.
B)that a direct relationship exists between oxygen consumed and the amount of heat produced in the body.
C)that measurement of oxygen consumption provides a direct estimate of how much fat is used a fuel source.
D)None of the above answers are correct

Question

Quizplus · Accepted Answer

Oxygen consumption and metabolic rate are directly related to the amount of heat produced in the body. This is due to the fact that oxygen is a critical component of the cellular respiration process that produces ATP (energy) in the body. As more ATP is produced, more heat is generated as a byproduct, and the body must use more oxygen to keep up with the metabolic demands of the exercise. Therefore, the measurement of oxygen consumption during exercise can provide an accurate estimate of metabolic rate. The other answer options are incorrect because oxygen consumption does not directly correlate with the use of specific fuel sources such as carbohydrates or fat.
