Lactate measurement is used by sport scientists and coaches to accurately determine Heart Rate training zones compared to performance levels and recovery. Lactate is a metabolic byproduct that can be measured by taking a drop of blood from an ear lobe. The blood lactate level increases with exercise intensity. A lactate "Step - Test" (The Lactate Profile Test) determines the transition from aerobic to anaerobic activity. The development of lactate during exercising is completely individual. The measurement of your lactate profile is a precise method for testing and monitoring training intensity and recovery. Lactate Testing is far more precise than the method of using percentages of maximum heart rate to set training zones. Because heart rate is an individual response, heart rate training zones need to be determined by individual measurements of physiological data. Additionally, the relationship between exercise intensity and heart rate is different for different sport activities. For example the heart rates for running will not be the same as heart rates for cycling, swimming, rowing, or other exercises for any intensity level. Training programs should not be based on general heart rate guidelines rather they should be based on individual parameters. Read More
