what is the lactate threshold
The lactate threshold (LT) (or lactate inflection point (LIP) or anaerobic threshold (AT)) is the exercise intensity at which lactate (more specifically, lactic acid) starts to accumulate in the blood stream.he aerobic threshold (AeT) is sometimes defined as the exercise intensity at which anaerobic energy pathways start to operate and where blood lactate reaches a concentration of 2 mmol /litre (at rest it is around 1).
