      I frequently run with both my Suunto 9 Peak and Garmin Fenix 6X, and the two devices yield vastly different VO2 max values while having similar averages for pace and heart rate. Unfortunately, (for better or worse, and true or not) the lower values suggested by the Suunto 9 Peak are discouraging to a novice, and they do not seem to coincide with my perceived effort. In fact, I also had a Suunto 9 and the VO2 max values from that more closely approximated the Fenix than those produced by the S9P. I wonder if this is a known issue?

        @matthew-robertson I do not know why, but I would trust your fenix more.

        @all Nevertheless you can not use VO2max as a fitness-indicator. It is strongly genetically limited and you should use a Lactat-Testing as a better indicator.
        Usually VO2max is used, because it changes quickly and is easier to measure.

            @theguyfromthesummit I know that it is not reliable but again it really annoying that you see a decrese every time 🙂

              @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.

                    @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

                          @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!
