questions about Evaluation & display of vo2max (without running)

Brad_Olwin

@cemoi71 If you do high intensity exercise that is something other than running, XCSki, Bike, etc. then I understand why you want a VO2M. I am surprised and would not trust in any circumstances a VO2M provided by walking no matter the manufacturer of the device. All devices I have tested, Suunto, Apple and Garmin provide a VO2M lower than lab tests for me. Not clear why you want a VO2M value.

@cemoi71 … Not clear why you want a VO2M value.

thx for your answer.
Because I had this value evaluated (I don’t in which situation it was to be honest), and in any type of activity we breathe, and therefore we have at one x moment an aerobic value with a maximum one.
Why i’ve lost this value ? i’m not dead.
I know that depends on which constructor, concepts and evaluations are differents.
But I find here by suunto not logical not to evaluate this value on other types of activities.
Maybe I would understand that by some activities which are less intensive the value is something different. But it makes still sense to evaluate it to have the history for the same kind of activities for seing the evolution and compares it with other one which are more intensive.

What would happens too by a kind of yoga which is really intensive ? I’ve done one time one which was as good as intensive like a good run. It goes in a trap? => not good I think.

I don’t understand the logic and the concept by suunto, not to evaluate it by some activities…
But I’d like to understand it…

@cemoi71 you cannot estimate VO2max from a yoga workout, because there is not pace/speed/power measured. It is as simple as that. The only way would be for you to do a lab test doing yoga, but I doubt there is a test protocol for that even in a very good lab.

Brad_Olwin

@cemoi71 A VO2M test in a lab essentially takes you to exhaustion and the gasses are measured. Yoga will not do that, neither will walking. Any other measure is an estimate at best and likely not all that reliable. The changes in VO2M from the watch might be more informative as they would indicate increase or loss of fitness. But this will depend on the type of exercise and the intensity. I do all my intensity training as a block near the beginning of training for a long race as my performance in the race is not heavily dependent on VO2M. IMHO people expect too much for this value and fail to understand its usefulness.

Todd Danielczyk

@Brad_Olwin Absolutely correct. VO2M in a clinical setting is looking at your intake volume and O2/C02 exchange rate for adenosine triphosphate metabolism.

Outside of an exercise medicine lab that masks your nose and mouth and monitors heart rate, it is only good for trends. I wouldn’t put a lot of stock in the numbers coming off my wrist.

I’ve read some website related to the subject in between.
I understand a little bit more about it.
I think that it something nice to observe his own evolution of it maximum capacity.
it should be measured hat the severity (red) zone.
I’m not an expert in science or mathematics.
But from a theorist point of you, I find quite sad that scientists or specialists use only a point in an half way.
Not only a maximum value at the highest range should be taken in account but the inverted one the the lowest. Just for general theorie.
And for an athlete should he really satisfied to have the max on his highest performance, on a range from x-days ?
I think its more interesting to have in addition to it, the average or highest value in lowest performance, by rest ( maybe by sleep).
Combined or the average of both on many days period. could be interesting…
And both the max and the min could reveal more info about the fitness of the person,
maybe it could reflect the illness or fatigue stand, or maybe if some limits have been exceeded.
That’s my point of view. vo2max is interesting to observe our own progress, but alone that’s not the highlight. That’s my feeling as not expert

@cemoi71 you are right, VO2max is interesting for some things, and in fact if measured correctly it can provide an upper bound on your endurance performance, but it is not everything, the same way that ATL/CTL/TSB is not everything, and HRV status is not everything, and so on.

cemoi71

@isazi yes hrv is a new element which I found interesting, and bring mit to have a deeper look on it and other tracking elements.

If I come back with my vo2max evaluation by polar.
I don’t know what is exactly the strategie from polar with the polar flow app.
But it seems there is a fitness test which is applied by rest (recommendation is to lie horizontally and relax. And (in my case is the verity sense hrm ) the sensor measures all what it needs during 5min.
By the recommendations the app describes it should be done regularly, at more or less the same times on the same place, better would be at wake up.
And not recommended. would be not to make high intensive exercises and/or drink alcohol the day before.
The app give then a vo2max value back.
I’d like to put some screenshots upon it, but I struggle somehow with my device to transfer, it on pc or in cloud for put it here afterwards.

But I’m a something confused, in comparison with the points that I’ve read till now and what all the people told here.
The value by polar flow is evaluated by resting and we should care not make intensive effort before.
For a couple of days I found it great to apply when I want. Have value after a rest, then after a strong effort. the perspective to track it on couple of days or weeks.
That’s a little bit weirds that the evaluation and the strategy differs with what I’ve read till now…

I will investigate further on it, bring some screenshots nearby for giving a better idea on it is.
But want to ask here, if someone knows about other kind of process of evaluation of vo2max?
If other tracked element could be called similarly and may be confused ?

cemoi71

have someone an idea if suunto plans to provide an hrm with leds (not only with ecg but maybe in combination with ecg) and adjustable with armband (not only ast breast-belt). ?

isazi

@cemoi71 I believe you are talking about the Polar orthostatic test, that does not measure VO2max, but HRV.

@isazi https://support.polar.com/en/fitness-test-in-flow-app?product_id=105848&category=fitness_tests
There is all explain and seems not to confuse with something else and is defined intentionally…

https://support.polar.com/en/polar-tests-which-one-is-for-me
nothing found for the othostatic test, despite on smartwatch…

Is better than my screenshot in which the app is in french and i’m not able to change it in other language because the app don’t give the access on this parameter…

cemoi71

ooh wait yes that’s seems to be the orthostatic test from polar… @isazi

in
https://support.polar.com/en/support/the_what_and_how_of_orthostatic_test
by the section “How do I do an orthostatic test?” the description is quite the same as the fitness test.
I’ll get a deeper look on it.
I’m little bit confused on why only the v02max is evaluated here, regarding about all we discussed before and the concept of evaluation of the value which is exclusive by red-zone…
