How do people approximately calculate their LT1 and LT 2 without a blood test?

On dfa a1 … if the developer of hrvlogger even says that it is crap [image] Richard H @RSH2468 @altini_marco I must be missing something... in Feb of '21, I downloaded your HRV Logger app based on your recommendation at the time that DFA alpha 1 could be used to determine LT1, and that …

[image] carytb: Well I’ve just had a bit of a reality check on my estimation of LT1. Did you have a chance to try again yet?

Curious about your reasoning/motivation to split endurance into @lt1, less than lt1, and way below lt1? Do you run? Looks like you are averaging a little under 6 hours/week - about 60 hours in your HR zones, about 36 hours with (cycling) power, and about 10 weeks since Jan 1. Are you running 24 hour…

Not yet.Until I’m reasonably proficient in drawing blood i’m just doing one offs when I get on the turbo. ie Gentle warm up then after 30 mins +20 Watts for 10m etc. My last one was 140W*129bpm @ 1.5mmol. I’ll take that as my limit until the next time I do one. I’m recovering from a couple of colds …

he is not saying it is exactly crap, but that it may have application if used in a more certain way, just like 4 mmol lactate is not the golden point to LT1… it is always more complicated when you talk about human physiology it seems. I know it does not likely work for me but still has some informa…

Just to add that the referenced study had 1min ramp test which makes it obsolete in my eyes. That is not to say that 0.75 is correct, but that the protocol of the study does not provide any valuable information. That being said, it would definitely not be surprising to see individual variation for D…

I alternate run/bike on a 14 day mesocycle so there’s approximately the same number of runs as bikes. I actually started forcing myself to run slower the last few years after having success biking easier for specific workouts. Staying far below lt1 when running for still involves some walking at ti…

As always, using a mean value without discussing the standard deviation is where using an absolute value for the thresholds can get you in to trouble. If we assume a normal distribution around the mean, it means it takes +/- 3 standard deviations to represent 99.7% of the population. So reporting …

I cite Seiler … ufff … [grafik]
