A VO2 test will also show the anaerobic threshold. The anaerobic threshold is the level of exercise intensity beyond which the body can no longer provide adequate oxygen to the muscles. Exercise below the anaerobic threshold should be comfortable even though the exercise extends for long periods. Exercise above the anaerobic threshold will improve cardiovascular fitness, but will also cause discomfort, fatigue, and muscle soreness.

Knowing the unique anaerobic threshold can be used to design a workout plan that will improve fitness and maximize calories burned. Measurement of VO2max or PeakVO2 will provide a true assessment of fitness level. The CardioCoach test will provide all of this data that is vital to proper fitness training. In addition, a CardioCoach test will also measure 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.
