Answer:
VO2 max
Explanation:
Maximum VO2, also known in the running world as VO2 max, is a sign of how well an athlete is doing. It is the maximum volume of oxygen the body consumes during exercise, and it also reflects the body's ability to absorb oxygen and transport it to various organs. The higher the maximum VO2, the more conditioned the athlete is.
Several factors affect the determination of VO2 max, such as age, gender, genetics, ethnicity, body composition, usual activity level and type of exercise.
