Calculating LT1 and LT2 approximately without a blood test?

Here is my summary:

  • HRV DFa1 may or may not identify LT1
  • Aerobic Decoupling may or may not identify LT1
  • Border of Coggan’s Power Zone2/Zone3 may or may not identify LT1
  • Talk test may or may not identify LT1
  • Gas exchange testing may or may not identify LT1
  • INSCYD or other power based tests that map you onto lactate curves, may or may not identify LT1
  • Given the 6 bullets above, everyone testing lactate for LT1 is wondering why the rest of us are too scared of blood draws or too cheap!
