SolarEnergy said:Hi Hamish, I am a bit curious. How do you define the two?
Aerobic threshold: we use 1mmol above resting lactate. Also roughly equates to 2mmol of lactate, 1st deflection point on a lactate curve, lactate threshold or onset of blood lactate accumulation.
Anaerobic threshold: we use the 2nd deflection point on a lactate curve. Also roughly equates to 4mmol of lactate, CP60, max lactate steady state.
Because we are doing V02 at the same time we can check these against ventilatory thresholds if the lactate curve is unclear.
While the two labs available to us in Christchurch use a similar protocol I appreciate that it's not exact science but the HR zones it gives us work very well guiding their aerobic training.
Because the testing also gives us max HR and MAP the zones we get from lactate testing match up very closely with both Ric Sterns, Andy Coggans and Peter Keens zones.
