What is commonly measured during a lactate threshold test?

During a lactate threshold test, the primary focus is on assessing blood lactate concentration at various exercise intensities. This test helps to identify the intensity of exercise at which lactate begins to accumulate in the blood, indicating a shift from predominantly aerobic metabolism to anaerobic metabolism. By measuring blood lactate levels at different workload intensities—typically during incremental exercise—fitness professionals can determine the lactate threshold, which is a crucial marker for endurance performance.

The lactate threshold provides valuable information for training, allowing athletes to tailor their exercise intensities for optimal performance and endurance adaptation. Understanding where this threshold lies helps in developing training regimens that enhance aerobic capacity and delay the onset of fatigue during prolonged physical activity.
