Answer 1

The amount of oxygen that is actually used by the body during rest or a hard workout is determined by the heart rate, the stroke volume, and the amount of oxygen removed from the vascular system.

The highest quantity of oxygen that a person can use when engaging in vigorous or vigorous exercise is known as VO2 max or maximal oxygen consumption. The best indicator of aerobic and cardiovascular fitness is usually thought to be this measurement.

Cardiovascular endurance is the capacity of the heart, lungs, and blood arteries to supply oxygen-rich blood to active muscles and tissues as well as the capacity of those muscles and tissues to use that oxygen for an extended length of time while exerting a moderate level of effort.

Your body needs more oxygen and creates more carbon dioxide while you exercise because your muscles are working harder. Your breathing must increase from approximately 15 times per minute (12 litres of air) when you are resting to up to about 40–60 times a minute (100 litres of air) during exercise.
