V02 and Metabolic Testing
PTS Sports uses the latest technology in exercise science. The VO2 and Metabolic testing performed at our facility is done with the CardioCoach by Korr Medical Technologies Inc. Using a breathing apparatus the CardioCoach measures the oxygen level of the athlete at various intensities. The Resting Metabolic Rate (RMR) test is done while sitting and measures calories consumed by the athlete at rest.
The VO2 Max test can either be performed on a treadmill or on your bike. The athlete starts out at rest and then progressively increases intensity until max values are measured. This test measures VO2 Max, Aerobic Threshold (AeT), and Anaerobic Threshold (AT).
What is VO2 Anyway?
VO2 simply stands for Volume of Oxygen. The VO2 test measures the volume of oxygen your body consumes at the various intensity levels during your test. The higher the workload you perform, the more oxygen your body requires to metabolize the energy needed. Since there is a direct relationship between oxygen consumption (VO2) and Calories burned, the test can also determine how many calories your body is burning at each intensity level.
The maximum rate of oxygen uptake (VO2) is called “VO2 Max”. VO2 Max is the Gold Standard method to measure fitness. Bottom line: a higher max = a higher ability to intensely exercise. For example, Lance Armstrong has a VO2 Max of 83.8 ml/min/kg. The average adult male has a VO2 Max of 35-45 ml/kg/min. To achieve a high VO2 Max, a person must have a fit heart and lungs and significant lean muscle mass that is well conditioned.
What is Aerobic Threshold (AeT)?
At low intensity activities your heart and lungs can easily supply all of the oxygen your body demands. The intensity level beyond which your body cannot provide all the oxygen needed is your Aerobic Threshold. Above this level anaerobic energy pathways start to operate. The greater your VO2 at your Aerobic Threshold, the greater your quality of life.
What is Anaerobic Threshold (AT)?
Your Anaerobic Threshold represents the maximum intensity level that you can maintain for an extended period of time. At high levels of intensity your body does not have sufficient oxygen to meet energy demands. Your body then uses anaerobic (without oxygen) energy sources which produce lactic acid. When you exercise above your anaerobic threshold your breathing will increase rapidly. It will be difficult to maintain this intensity level for a long period of time. Exercising at your Anaerobic Threshold Heart Rate will increase your performance in endurance activities.
How will these values help fitness and training?
The VO2 test can determine an athletes Aerobic Threshold and Anaerobic Threshold. Once the athletes Aerobic Threshold and Anaerobic Threshold are determined, the athletes true target workout zones can be found. The target workout zones are based on the athletes heart rate. With this information the athlete will know at what intensity (heart rate) he/she can train to improve fitness and endurance.
What is Resting Metabolic Rate (RMR)?
This is the number of Calories your body would burn if you did nothing more than sit in a chair all day. This is similar to what is know as Basal Metabolic Rate (BMR). Your resting metabolic rate is related to your lean body mass or the fat-free part of your body. Your lean body mass is made up of muscle and internal organs.
When you move your body it burns energy. The more you move, the more energy you burn. Your activity during the day is the biggest part of your body’s energy output that you have control over.
