VO2 is the rate of oxygen uptake, or consumption, measured during exercise. The maximum rate of oxygen uptake is called the VO2max. VO2max is the ultimate measure of endurance fitness and is reported in milliliters of oxygen per kilogram of body weight per minute or ml/kg/min. To achieve a high VO2max, a person must have a fit heart and lungs and significant lean muscle mass that is well conditioned.
Measurement of VO2max or PeakVO2 provides a true assessment of an individuals cardiovascular fitness level. The test provides all of the data that is vital for effective training prescription. In addition, the test also measures how many calories are burned during a workout at every exercise heart rate level. This information, along with a heart rate monitor, or a heart rate equipped bike or treadmill, can be used to calculate the precise amount of calories burned during a workout.
However, Vo2max is not the only component related to endurance performance. Most importantly, the performance test will identify the Anaerobic Threshold (AT) or Lactate Threshold (LT). The anaerobic threshold is the single best indicator of endurance performance. The AT is the maximal lactate steady state (MLSS) which is the level of exercise intensity beyond which the body can no longer provide adequate oxygen to the muscles. Exercise above the anaerobic threshold will improve cardiovascular fitness and improve endurance performance. Knowing your unique anaerobic threshold is used to design a workout plan that will improve fitness and maximize performance.
In addition, the performance test also identifies the Aerobic Threshold (AeT). Exercise at the AeT is comfortable even though the exercise extends for long periods, improving endurance abilities and burning many calories. Training at the AeT provides a precise training parameter for reducing wasted training time.
The CardioCoach Plus from KORR Medical Technologies that PR LLC utilizes delivers simple and accurate fitness testing. It measures key data including peak VO2, anaerobic threshold (AT), aerobic threshold (AeT) and the precise amount of calories burned at all exercise heart rate levels. This data can be used as the foundation for customized exercise programs that truly meet the needs of the individual. One session with the CardioCoach empowers clients with the ability to meet their fitness and performance goals efficiently and safely with no unnecessary fatigue or wasted time. The CardioCoach Plus also measures Resting Metabolic Rate (RMR) to aid in constructing personalized weight loss programs.
Since true VO2max measurements require exercising to the maximum level of exertion, they should only be done under medical supervision, or by persons who have been cleared to exercise extreme exertion by their physician. Peak VO2, or the maximum level of oxygen uptake achieved during a sub-maximal test can also be used to predict the VO2 max had the test been allowed to progress to the predicted maximum heart rate.
