Individual anaerobic threshold, aerobic threshold, 4 mmol threshold and so on ... There probably are many more terms to describe this “mysterious“ threshold so many pieces have been written and lectures been held on. Instead of wasting time defining a name for this threshold, we would rather like to explain what it is all about:
The anaerobic threshold (as we call it) is not the transition from aerobic to anaerobic metabolism. And the allegedly occurring acidification is not the reason for the break-off when riding / running at the anaerobic threshold, either.
