That’s more for AeTTalk test should be good enough IMHO.
Yep.That’s more for AeT
I've heard the same cliffs notes version. One hour for AnT, three hours for AeT.Yep.
Talk in complete sentences for aerobic threshold. A few words for anaerobic threshold. For an activity you are relatively proficient in it's an effort you can sustain for approximately an hour.
Well seasoned endurance folks can go way longer than 3hrs at or close to AeT…I've heard the same cliffs notes version. One hour for AnT, three hours for AeT.
Modalities do matter. That’s why when you actually test (AeT or AnT) properly, you should use the modality in question; e.g running or cycling.I think with respect to anaerobic threshold it does depend a bit on modality as well. For the most part and for most modalities, one hour max sustained (consistent) output is a pretty good baseline.
Cliffs Notes, not The Gulag Archipelago .Well seasoned endurance folks can go way longer than 3hrs at or close to AeT…
Does this have to do with different max HR on modalities? In running your body is supporting your weight while cycling the frame of the bike supports your weight and the heart has to work less? Swimming even lessModalities do matter. That’s why when you actually test (AeT or AnT) properly, you should use the modality in question; e.g running or cycling.
Definitely that is a large part of itDoes this have to do with different max HR on modalities? In running your body is supporting your weight while cycling the frame of the bike supports your weight and the heart has to work less? Swimming even less
Here are the words of Inigo San Milan, the mitochondria maestro:
Quoting:
Can we please start placing “anaerobic threshold” where it really belongs? . It is not that difficult.
Anaerobic threshold means the transition from an aerobic state to an anaerobic one. That happens at your VO2max when you reach your maximal aerobic capacity and past that point, muscle cells need to rely on the ATP/PC system for muscle contraction, which is purely anaerobic. We are talking about pure sprinting to a maximal of 1-2 min efforts…
But please, the term “anaerobic threshold” to describe a “transition” point from low to high intensity is NOT anaerobic by any means. During those 5-10-20min efforts where very high intensity efforts are deployed, “anaerobic threshold” is where it is mostly used. There is a massive lactate production due to high glycolytic flux and this lactate can be produced under FULLY aerobic conditions.
End quotes.
A simple test is to do a ballsey do or die 400m sprint. Other tests are available but for non specialist endurance athletes this is a solid marker of aerobic power and anaerobic power. Beep tests too are simple proxies.
1. A thought for anyone (but I'm thinking of @offwidth in particular):
If we subscribe to 5 HR zones per the Polar app and many other sources, could we say that, for some/many/most people:
AeT is around the Zone 2-3 border?
AnT is around the Zone 3-4 border?
BTW, I claim nothing about the above, just a through that occured to me as I finished a set of AXE swings and was looking at my HRM via the Polar Beat App.
2. If I would like to have myself tested for Aet, Ant, Max HR, Max Headroom (alert - '80's reference), Stress Test, and whatever else, where should I look? Doctor? University Kinesiology Department? Big gym?

A place like this. A key piece of their equipment is currently out of order, however.1. A thought for anyone (but I'm thinking of @offwidth in particular):

This is great Brian and probably as clear an explanation as I have read.Steve…
Yes.
AeT at top of Z2 (i.e. the Z2-Z3 border)
AnT (aka LT) the top of Z3 ( the Z3-Z4 border)
Z4 is the range from AnT to HRmax. Typically only seen in (training) efforts ranging from 30sec to about 8min in duration
Z5 by contrast is HRmax effort that can only be performed in the sub 60sec duration.
As far as testing goes…
(And it depends upon how accurate you want the results)
Doctor… most likely not… unless it’s a cardiologist doing a stress test, and they will likely want a good reason to do so…
University Kinesiology Department….. yes. Especially if they have gas exchange apparatus.
Performance Testing Centres (like what @Don Fairbanks just posted)
Some personal coaches who specialize in running and cycling often do Blood Lactate testing for AeT, and also offer AnT testing. I have a guy…
DIY AnT testing is relatively straightforward and accurate.
HR max can be done in a DIY fashion, but like the Stress Test… I would prefer to have somebody standing by with the paddles…
Something I did not know until a few years ago is that VO2max testing may or may not give you good results for AeT and AnT, depending upon how they administer the tests. But then again, I am not a big fan of VO2max being that meaningful of a metric anyway.
I probably slightly disagree with @JPCross about AnT in well trained endurance athletes being closer to the top of Z4. I would rather say that in these athletes Z4 starts at a higher HR than in lesser trained individuals. Their Z2 is also at a higher rate, and that they have a compressed Z3. Additionally they can stay in Z3 and Z4 for a longer time.
Well… let me rephrase that a bit if you will allow me…This is great Brian and probably as clear an explanation as I have read.
As an aside, appreciate your thoughts on why VO2 max is not a meaningful metric.
