Maximal Oxygen Consumption; also known as VO2max, is defined as the highest rate at which oxygen can be taken in and used by the body every minute during intense exercise (2). It is measured in mL/kg/min, defined as the milliliters of oxygen per kilogram of body mass per minute. VO2max is generally measured by using a maximal exercise test to physical voluntary exhaustion where speed or power are increased consistently, requiring more oxygen uptake each phase. (1) Exercise intensities are characterized into four domains based on the oxygen uptake (VO2) response: moderate, heavy, severe, and extreme (3)(4). The moderate domain is comprised of all exercise intensities that can be performed without a change in blood lactate levels in relation
