Calculating LT1 and LT2 approximately without a blood test?

@Bioteknik

So I’m wondering if most people who move their curve to the right are just improving vo2max, which is why hr stays stable at either threshold. In the fitter version of you, lt1 is still x% of vo2max.

If you are truly changing the shape of your curve and increasing your fractional utilization, does that not change the hr at your thresholds? It appears very fit individuals have relatively high hr at their tested thresholds, but haven’t seen what those are as a % of hrmax. Robert has said that his hr stayed the same, but his max has significantly changed.

@Bioteknik I know this response is old but I’ve been trying to parse this since you posted.

Specifically this ^^^^^^

This is the section of the TTS podcast that reminded me:

(Can we move the lactate threshold independently from the critical power?)
