What is lactate inflection point and OBLA?
The term lactate inflection point (LIP) is now the preferred term used to represent a number of previously used terms such as anaerobic threshold, lactate threshold and OBLA (onset of blood lactate accumulation). The LIP can be established by graphing the results of blood testing during incremental exercise (exercise that progressively increases in intensity). The LIP occurs where there is a sudden exponential or non-linear increase in the lactate concentration in the blood (refer Figure 2.16). The LIP reflects the balance between lactate entry into the blood (commonly referred to as lactate appearance) and lactate removal from the blood (lactate disappearance). The sudden increase occurs when the rate of lactate appearance exceeds the rate of lactate removal or disappearance. See figure in link.
