When you are performing aerobic exercise at an intensity near VO₂ max, the predominant oxidative substrate is carbohydrate.
The maximum rate at which our body can use oxygen during exercise is known as VO₂ max. When one exercise as hard as they can, their VO₂ max evaluates how much oxygen (often measured in milliliters) they breathe in. The body may use a greater amount of energy the more oxygen one breathe in. Better physical fitness typically translates into a higher value. Most people agree that the best measure of cardiorespiratory fitness is this value. It displays the maximum amount of oxygen the body can take in while exerting itself. The more oxygen the body can consume, the better is aerobic fitness, and the higher is the value of VO₂ max.
