Lactate Threshold Pace, Heart Rate, and Power all refer to the maximum effort you're able to maintain with mostly aerobic energy systems. For most trained athletes, this is similar to the maximum effort they can maintain for an hour. Going above this threshold effort will result in a "burn" in the muscles and, after a few minutes, require This method is simple and easy to use, but it does require an accurate measurement of your maximum heart rate. Lactate Threshold Testing: Lactate threshold testing involves measuring the level of lactate in the blood during exercise. As the body begins to rely on anaerobic metabolism, lactate levels will increase. The Lactate Threshold is sometimes referred to as the first turning point (LT on the above graph), however, you need to know when a sustained rise occurs, which is the Lactate Turning Point (LTP on the graph — LTP is the same thing as LTHR). This an important metric for an athlete to be aware of. Lactate testing is a test done to determine your lactate threshold and establish training zones based on actual metabolic conditions within your body. Zones ascertained this way, therefore, have better physiological validity than zones based on FTP, FTPa or heart rate (e.g. max heart rate) anchor points. Lactate testing can be done in the field Lactate Threshold Heart Rate. As we discussed in the previous sections, the heart rate we assign to each threshold should be based on physiological data collected during the test. However, I often see athletes and coaches use fixed percentages of a maximal heart rate as a marker. For adults aged 18-39 years, a lactate level of 4.0 mmol/L or higher was associated with a mortality of 5% or greater; for adults aged 40-64 years, this threshold decreased to ≥ 3.0 mmol/L; for adults aged 65 years or older, a lactate level of ≥ 2.0 mmol/L was associated with a 5% or greater mortality rate (Figure 2, p <0.0001).
