We check out some old research to find the origins of common lactate myths like its role in fatigue, its acidity, the "anaerobic threshold," and whether it's a metabolic dead end. Then we correct the record with modern science while figuring out how smart scientists came to the wrong conclusions.
History of lactate papers:
Detailed look at acidity in metabolism
Experiment with sprints, 20 vs 120 second rests
Lactate in trained vs untrained cyclists
