What does a vo2max measurement reveal?
a. the amount of oxygen delivered to body tissues
b. the amount of body fat burned during physical activity
c. the amount of blood that flows through the heart per minute
d. the amount of oxygen that the lungs can hold at full capacity

A is correct. The amount of oxygen delivered to body Tissue

Explanation:

Maximal Oxygen Uptake

Determining maximal oxygen uptake (VO2max):

It is the best measure of cardiorespiratory fitness;

It reveals how much oxygen is delivered to body tissues; and

It requires an exercise physiology laboratory with trained personnel to analyze a person’s oxygen intake.

Maximal tests can be substituted with field tests, which are a comparable way to score the VO2max. They are less expensive, require little to no equipment, and are, therefore, more practical.
