VO2max
- 
 @djordje-s Ahh ok have you changed anything in terms of intensity/ volume? 
- 
 @djordje-s I think it may be because of walking. If I do a few runs in a row, my VO2max grows nicely, but a couple of longer walks sink the value. 
- 
 @theguyfromthesummit 
 I havent.Basically standard route with little change.
- 
 @dmytro So to try with few running and to see what is happening?  
- 
 @djordje-s I’d suggest more running, less walking. 
 My walks also work if hr is elevated enough + speed is above 6.5kmh
- 
 @dmytro and multisport? Walking+running 
- 
 @djordje-s I’m not sure if multisport activities are contributing to VO2max. You can check this by performing an activity, then looking for it in the VO2max tab in SA. 
 I just want to say that it’s my personal experience. When I go hiking my vo2 plummets as only horizontal speed is being considered by the algorithm. When I go walking - I’m not sure: maybe the algo considers my HR for the speed to be too high, or maybe HR is just not high enough to provide a reasonable dataset for extrapolation.
 I heard from people on the forum that both walking and running results in reasonable VO2max values.
- 
 @dmytro Also one observation.My VO2max was also low before hard reset.After that the value was high and now it decresing after every exercise  
- 
 @djordje-s well, it makes sense. If algo before the hard reset considered your vo2 to be low, after you’ve reset the values, it needed time to converge to the similar value. 
- 
 @djordje-s or do you mean that v02 is now even lower? 
- 
 @dmytro Its not lower as it was before hard reset but if it continue like this,it will reach old value  
- 
 @djordje-s it kinda makes sense then. The algo needs a couple of weeks to stabilise. 
- 
 @dmytro In that case I will continue to monitor and try with more running exercises…Thank you all for prompt support and reply.  
- 
 @theguyfromthesummit thanks for the reply. I agree, nothing from a watch is going to be as valid or reliable as a controlled test in a lab. That said, I do find some encouragement from the numbers changing over time. Also, I too feel the Fenix is more accurate given my resting HR, training volume, and general health, but I can’t prove it. Overall, I mostly run by perceived effort - for better or worse… 
- 
 Mine has been 52.9 for as long as I can remember despite obvious losses and gains in fitness. I don’t know if there’s a glitch on my S9B or it’s just never really worked from the outset 
- 
 We all know that walking activities have a bad effect on VO2Max calculated by Suunto/Firstbeat. I would strongly suggest to be able to turn off VO2Max calculation before launching an activity on the watch! 
- 
 @v-sacre yup, that would be very helpful. For hiking as well. 
- 
 @dmytro Well I doubt that Suunto will improve algo related to VO2max for S9 as probably all efforts will go for further models but to introduce few opyions like disable/enable would be nice 
- 
 @djordje-s Definetly with running VO2max is increasing. That leaves a question. If VO2max is measured only with walking and running and if it is not reliable for walking, it means that 50% of this feature is useless  
- 
 @djordje-s it definitely is. 
 Now my watch says 49 but actually my VO2max according to a lab test is 56…
