Oxygen consumption is essential to sustain life. The ability to take in and utilize oxygen is necessary for optimal health. At rest everyone consumes 3.5 ml/kg/min. which is one metabolic equivalent to oxygen consumption or MET. METs are used to gauge the intensity of activities based on oxygen consumption. In the American College of Sports Medicine Guideline for Exercise Testing and Prescription, there is a table of activities from A to Z and a range or MET values associated with each activity. The MET level is multiplied by 3.5 to yield a volume of oxygen consumption (VO2) value expressed in milliliters of oxygen per kilogram of bodyweight per unit of time which is one minute. The product of the bodyweight in kilograms and the time engaged in the activity or exercise yields milliliters of oxygen consumed and utilized. The milliliters are divided by one thousand to give liters of oxygen consumed. The liters of oxygen are them multiplied by five to calculate the calories burned for ...

Basal metabolic rate (BMR) is the rate of energy expenditure per a unit time at rest. It can be expressed in units ranging from watts, milliliters of oxygen consumption per minute, or joule per hour per kilogram of body mass. The amount of oxygen an individual takes in and utilizes at rest is equal to 3.5 milliliters of oxygen per kilogram of body weight per minute or one Metabolic equivalent to oxygen consumption referred to as one MET. METs estimate the intensity of aerobic activities based on oxygen consumption during and compared to a resting state. Proper measurement of BMR may be met by assigning specific criteria. BMR may also be expressed as calories needed to maintain normal basic physiological function . This  is the minimal number of calories necessary for normal function not including any activity. BMR can be calculated by using several equations. The Harris-Benedict is one of the most popular equations for calculating BMR. BMR may also be referred to as resting metab...
