Lactate threshold setting

[halajos]

@ChrisA the definition of lactate threshold is unambiguous across articles, publications. In practice there a two kinds of metabolic thresholds, which can be determined by plotting lactate levels as the function of exercise intensity. The first is the intensity at which lactate levels start to rise above resting level. This is usually called aerobic threshold (which term is also not used consistently). The second threshold is above that, and is called anaerobic threshold, the definition of which varies across articles and studies. The key characteristic of this second threshold is that exercise at this intensity can be continued only to a limited amount of time (up to an hour or so AFAIR). This upper threshold is what should be treated as LT and to set the upper limit of Z4 in a 5-zone system. Your HR of 149 looks to me like the lower threshold, which is the upper limit of easy/moderate intensity.
I don’t know which threshold the algorithm int the watch is meant to determine.

@halajos thanks, that’s actually what I think too and what makes sense for me. I will try some tests and see what happens. Thanks to @fluca for hinting to use a HR strap, I own a Polar H10, which should do the job .

@halajos very good explained You wrote about the VT1 and VT2 Treshhold right?!

[halajos]

@GiPFELKiND there are different terminologies, but they basically mean the same. Some refer to them as ventilatory thresholds (VT1, VT2), others as lactate thresholds (LT1, LT2). And MLSS (maximial lactate steady state) as well as critical power/speed are also used, which are different approaches to the upper threshold.

Hi! Is there any way to see lactate in the suunto app or just in the watch?

@Matija-S please don’t post the same question in different threads.

@isazi please LINK then here the other Post…

@Matija-S I didnt have this values since i have the Race … Not in watch! Do you have this!?

[Matija S]

@isazi sorry, I didn’t find the newer post at first….
I will continue in the other post here :

@GiPFELKiND I read along here diligently and your approach sounds logical.
After my lactate test with the sports physician, I was given the training recommendation to avoid over-acidification in the GA1 zone, i.e. to stay at a maximum of 157 bpm. This allows me to train in the aerobic zone without accumulating lactate, which is ideal for long endurance workouts.
I now have a new max HR and a lactate threshold of 165 according to the Dmax model (see screens).
My watch suggests 161. How can I change this value?
You have also adjusted the value, haven’t you?

Thank you for your input.
