VO2 Based Metabolic Fitness Testing allows you to eliminate any guesswork from your training program, maximize your training time, pinpoint your strengths, weaknesses and assist you with achieving your goals.


A VO2 max test finds the body’s maximum ability to consume oxygen, an indication of physical fitness. Alone, that number may not mean much to anybody other than athletes looking for bragging rights amongst their buddies. However, from that number we can estimate your lactate threshold—the point at which muscle fatigue sets in, forcing you to slow down—determine personalized heart rate training zones, and tell you how many and what type of calories, carbs or fat, you’re burning within those zones.


The resting metabolic rate test determines how many calories your body burns at rest, which will help you decide how many calories you need to eat every day to lose, maintain, or gain weight.


With an assessment, you get a training program that is based specifically on the data that is YOU. Your resting metabolic rate. Your required calories. Your calories burned. Your fuel composition. Your base heart rate. Your threshold heart rate. Your fat-burning efficiency.

How does metabolic testing work?

Indirect calorimetry (a measurement of metabolic rate) relies on the fact that burning 1 calorie (Kilocalorie) requires 208.06 milliliters of oxygen. Because of this very direct relationship between caloric burn and oxygen consumed, measurements of oxygen uptake (VO2) and caloric burn rate are virtually interchangeable.

Oxygen uptake requires a precise measurement of the volume of expired air and of the concentrations of oxygen in the inspired and expired air. The process requires that all of the air a person breathes out be collected and analyzed while they rest quietly. The KORR™ indirect calorimeters contain a precision air flow sensor that measures the volume of expired air, and an oxygen sensor that measures the concentration of oxygen. Once the factors of humidity, temperature and relative humidity are accounted for, the KORR™ instrument provides the most accurate results available in a compact metabolic analyzer.

What is Resting Metabolic Rate (RMR)?

Metabolism, quite simply, is the conversion of food to energy.

Metabolic rate is a measure of how much food, or fat, is converted to energy in a day. Resting metabolic rate (RMR) is the measurement of how much food, or energy, is required to maintain basic body functions such as heartbeat, breathing, and maintenance of body heat while you are in a state of rest. That energy is expressed in calories per day. So an RMR test shows how many calories you burn at rest, doing nothing more than sitting in a chair.

What is a VO2 Max test?

A VO2 Max Test is a measurement that reflects a person’s ability to perform sustained exercise. It is generally considered the best indicator of cardiovascular fitness and aerobic endurance. The actual measurement is “milliliters of oxygen used in one minute per kilogram of body weight.” It is suitable for a wide range of individuals, from the sedentary to elite athletes.

How is VO2 Max measured?

VO2 Max is the maximum rate of oxygen consumption that can be attained during the most intense exercise possible. The measurement requires that the subject breathe into an oxygen consumption analyzer during an all-out effort (usually on a treadmill or bicycle) as part of a graded exercise protocol. These protocols involve specific increases in the speed and intensity of the exercise. While exercising, the person wears a mask to collect all the air he breathes in and out for a measurement of the volume of exhaled gas and the concentration of oxygen in that exhaled gas. This determines how much oxygen is used during each minute of the exercise test.

A person’s oxygen consumption rises in a linear relationship with exercise intensity — up to a point. There are specific physiological markers (AeT, AT) that can be detected throughout the test as oxygen consumption is measured. Eventually, oxygen consumption plateaus even if the exercise intensity increases. When the person is no longer able to keep up with the oxygen demands of his muscles and complete fatigue forces him to stop exercising, then his oxygen consumption has reached a maximum, and VO2 Max can be calculated. The test usually takes between 10 and 15 minutes.

Why test VO2 Max?

A complete VO2 Fitness test can give trainers and clients the tools to set realistic goals and assess improvement. Studies show that previously sedentary people training at 75% of aerobic power for 30 minutes, 3 times a week over 6 months increase VO2 Max an average of 15-20%. Many people are inefficient exercisers, with no understanding of what specific heart rate, intensity or duration would best help them reach their specific goals such as fat burning, endurance training, or cardio conditioning. An initial VO2 Max test can clarify the specific target heart rates that will enable each individual to reach their fitness goals more effectively, with less fatigue and fewer injuries. Periodic retesting provides motivating feedback as the fitness program progresses.

The test also determines the number of calories burned during every level of exercise, providing valuable information when designing a weight loss program. And if CO2 is measured during the test, a Respiratory Exchange Ratio (RER) can determine the proportion of energy coming from carbohydrates and fats at various levels of exercise intensity. Since physical conditioning and exercise intensity affect these proportions, this information can be very helpful when designing a workout intended to burn fat.

VO2 Max testing is a valuable tool for serious athletes to assess performance and evaluate training regimens. Even though extensive training can sometimes cause an athlete to reach a plateau in VO2 Max, he can still use his VO2 Max test results to make further improvements in performance. This is accomplished as he pushes to increase anaerobic threshold (AT) and maintain that threshold for longer periods of time. This enhances both endurance and cardiovascular performance.

What is Aerobic Threshold?

Aerobic threshold (AeT) is the first rise or breakpoint in the ventilatory response to increasing rate or grade of exercise. (Sharkey 2002) CardioCoach detects the rise in the ventilatory response and correlates it to your heart rate. The aerobic threshold defines the minimal level of effort that can produce improvement in cardiovascular fitness.

What is Anerobic Threshold?

The anaerobic threshold (AT) is defined as the level of exercise intensity at which lactic acid builds up in the body faster than it can be cleared away.  Lactic acid build up generally leads to muscle fatigue and soreness. Vigorous effort can be sustained for an extended duration at exercise intensity levels below the anaerobic threshold. AT can be detected by 2 different means: Ventilatory Threshold, or Respiratory Exchange Ratio threshold.

Respiratory Exchange Ratio (RER) is the ratio of expired carbon dioxide to oxygen uptake at the level of the lung. When Carbon dioxide production exceeds oxygen uptake, the RER crosses 1.00. This is anaerobic threshold.

Ventilatory Threshold (VT) is the point during progressive exercise in which ventilation increases disproportionately to oxygen uptake. Ventilation increases to rid the body of the excess Carbon dioxide from lactic acid build up. AT is detected by pinpointing the take off (rising) point in the Ve/VO2 ratio.  (Meyers, 1996)

What is the difference between Anerobic and Lactate Threshold?

Lactate Threshold is a reference to the accumulation of Lactate in the blood. There are some inconsistencies in the terminology, though. Some use the term to denote the initial rise in lactic acid production. More often, Lactate Threshold is used to describe the maximum steady state effort that can be maintained without lactate continually increasing.  This abrupt increase in blood lactate levels is also referred to as the lactate turn point (LT), lactate inflection point (LIP), or onset of blood lactate accumulation (OBLA). (Roberts & Robergs 1997)

The Anaerobic Threshold is defined as the level of exercise intensity at which lactic acid builds up in the body faster than it can be cleared away.  Because this is measured by Ventilatory responses (Ve/VO2 or VO2/VCO2), it is often more accurately termed Ventilatory Threshold (VT). (Meyers, 1996)

Do you need to measure CO2 to detect Anerobic Threshold?

The key to determining Anaerobic Threshold (AT) during a VO2 Max test is to detect the point when the body is forced to expel the surplus CO2 produced as a result of excess lactate. This can be determined one of 2 ways:

  1. Measuring VCO2/VO2 (volume CO2/volume O2) and detecting the point when that ratio (RER) equals 1.00. This is the Respiratory Exchange Ratio method.
  2. Measuring Ve/VO2 (Minute Ventilation/volume O2) and detecting the respiratory compensation point. This is the ventilatory equivalent method.
Does VO2 Max change with age?

For men and women, VO2 Max will decrease by 10% per decade regardless of age and exercise activity.

How should you prepare for your test?

Various activities may influence your metabolic rate and should be avoided before testing.  For at least 8-12 hours before your test you should not eat or drink anything.  You may drink water as needed. Exercise or physical labor should be avoided the day before the test.  You will be wearing an heart rate monitor during the test, so try not wear fabric which might be static. Take your medications as prescribed unless directed otherwise by your doctor.
