Lactate Testing

So how to get LT1 and endurance training power target from lactate testing results?

LT1 is defined as the first inflection point in the lactate concentration vs power graph

Common definitions with similar outcomes are:

  • first rise above baseline
  • baseline + 0.3 mmol/L
  • first inflection point

folks with a very weak base may not even have a baseline/first inflection point


thanks for the clarification

There are at least 25 different definitions of (criteria for determining) lactate threshold.

Table 1 lists the various criteria used to identify ‘LT1’.
