It is the product of total blood flow or cardiac output (CO) and the oxygen content of arterial blood and is usually expressed in ml O 2 /min. VO 2 is sometimes expressed in liters of O 2 per minute (liters per minute). One verified way to increase your VO2 is by modifying your training routine by adding more high-intensity exercises.
