lactate threshold
The point during exercise of increasing intensity at which blood lactate accumulate faster than clearance rate. Recruitment of type II x fibers a critical factor. happens around 50-60% VO2 max in untrained subjectsThe point at which there is a sudden increase in blood lactate concentration during incremental (graded)exercise is termed the lactate threshold
The lactate threshold is the point during exercise at which lactate production exceeds lactate clearance. During low to moderate intensity exercise, the body is able to clear lactate as quickly as it is produced. However, as exercise intensity increases, the body is unable to clear the lactate as quickly, and lactate begins to accumulate in the blood.
The lactate threshold is a useful measure for athletes as it indicates the intensity at which the body switches from primarily using aerobic metabolism to anaerobic metabolism. This is important, as anaerobic metabolism is less efficient and produces less energy, meaning that an athlete cannot maintain this intensity for extended periods of time. Therefore, knowing an individual’s lactate threshold can help them to design their training program and optimize performance.
There are several methods to determine an individual’s lactate threshold, such as blood lactate testing during exercise or the use of heart rate monitoring. Once this threshold has been identified, it can be used to set individual training zones and help an athlete to improve their fitness and performance.
