Oxygen consumption, or VO2, typically increases with exercise intensity but doesn't follow a simple linear relationship. For many individuals, VO2 can increase by approximately 10 to 20 times from rest to maximal exercise depending on fitness level and exercise type.
In trained athletes, this increase can be closer to 4 to 6 times resting levels during high-intensity exercise, while untrained individuals might see greater relative increases. However, as exercise intensity continues to rise, oxygen consumption will eventually plateau at a level known as VO2 max, which is the maximum amount of oxygen the body can utilize during intense exercise.
So, in short, oxygen consumption can increase significantly—often up to 10 times or more, but it typically plateaus at VO2 max rather than continuing to rise indefinitely.
