Maximal Lactate Steady State
You’ve probably heard about lactate threshold, the intensity level that indicates where lactate accumulation begins to exceed that at which lactate can be cleared and lactate concentration level increase. The ability to delay lactate accumulation can be increased with consistent aerobic training.
Lactate threshold is typically 50% to 60% of maximal oxygen uptake in untrained people and 70% to 80% in aerobically trained people.
The maximal lactate steady state is the point at which lactate and clearance are both equal. It is important to know because this is the highest intensity an athlete can perform at before crossing into lactate threshold, which results in performance decreases and higher level of fatigue.
When training is important to know if you are increases efficiency of maximal lactate steady state, lactate threshold or a different energy zone. One intensity is not necessarily more important than another on it’s own but it will depend on the specific goals you are trying to achieve. As you train in a certain intensity you will before more efficient at that intensity and it will require you to exert less energy at that same pace.
