Articles about lactate testing and endurance training.
Lactate threshold marathon pace depends on which threshold you mean. One fictional step test gives marathon projections from 2:46 to 3:22.
Measured lactate values become useful when intensity, curve shape, LT1, LT2 and zones are interpreted together.
How LT1 and LT2 help apply the 80/20 model more precisely in endurance training.
Lactate-based zones show where metabolism actually changes, instead of relying on generic percentages.
