"Ein Punkt ist unumstritten, Laktat entsteht im Körper bei der Verbrennung von Kohlenhydraten unter anaeroben Bedingungen, also ohne Beteiligung von Sauerstoff."

Wenn ich das hier richtig verstehe, ist nicht einmal unumstritten, ob es überhaupt eine anaerobe Verbrennung gibt:
"However, more recent efforts by experts using new techniques to determine if muscles become anaerobic during heavy exercise have shown the opposite to be the case: “these data demonstrate that, during incremental exercise, skeletal muscle cells do not become anaerobic…since intracellular PO2 (the oxygen pressure in the muscles) is well preserved at a constant level, even at maximal exercise.”(2)

So, you now know that muscles do not become anaerobic during exercise."

Und weiter:
"In essence, then, lactate is a by-product of carbohydrate metabolism. It is not a matter of the body becoming anaerobic."

There is NO Lactate Threshold
