      @placebo If you want a more hands-on evaluation of the differences than pure math, I’ve written about my experience with DFA as seen through the Garmin CIQ datafield AlphaHRV at:

      “Let’s hope for something as good as ZoneSense??”

      https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-965/385558/let-s-hope-for-something-as-good-as-zonesense/1864901#1864901

      Further down in the thread I give a multi-post review (upon request) of my initial sightings of DDFA through Suunto ZoneSense.

      To conclude: DFA is not ‘actionable’ without a lot of post-exercise analysis of the individual’s data (fixed thresholds like VT1 at 0.75 and VT2 at 0.5 have been debunked) and an extremely controlled environment. The DDFA as implemented by Suunto seem to be of use in the field, at least when it comes to separating the Aerobic from the Anaerobic effort - and this because the athlete’s actual HRV inflection point of the day is detected. Whether this holds true also for the upper efforts in the VO2Max area I have yet to examine.

        @Inge-Nallsson Hi, thank you!!! I currently use a Garmin watch and am a big fan of that application. As soon as I read that Suunto implemented DDFA I became interested and now I’m curious to read your thoughts! I will let you know…

          That thread is an interesting read, in addition to being an antidote to the (sometimes) negative opinions that appear here about functionality etc. offered by Suuunto. I almost laughed out loud when I read…

          It seems that the grass is indeed always greener on the other side 🤣

            @wakarimasen the grass is very shiny green on my Vertical side. 😂

              It strikes me that a vast majority of the reviewers of athletic / tech equipment haven’t posted much about zonesense . Eg @dcrainmaker hasn’t mentioned anything or so

              As I am far from proper athlete , I find it challenging to understand how zonesense really works , but it gives me a direction which is quite interesting

                      that system looks interesting, how are you liking it?

                        @stromdiddily So far I am liking it. You need to have the belt to unlock all the features in the app. Currently no Suunto integration but maybe at some point. I pair it to my watch but also sync to the Morpheus app. They calculate your HR zones daily based on recovery so they are dynamic as opposed to the static ones most go by.

                          I did an FTP test on Zwift yesterday. Zwift concluded that my FTP is at 284W. I was running ZoneSense on my Suunto Race. As hown in picture below, ZoneSense i the Suunto app indicated that i was going from anaerobic to VO2 max at ~284W. This single test shows very prommising results.

                            ZoneSense is possible with the Ambit series? Wow - I did not know. I almost asked about this a few days ago, bit assumed it was a stupid question 🙂
                            How does this work in practice, as I thought the app had to be activated in the watch?

                              @wakarimasen no, you also get ZoneSense data in Suunto app retrospectively for all exercises, which have R-R intervals data (that’s true for all exercises done with the Suunto smart sensor, Polar H10, etc.)

                                  You will not see ZS live on the watch, which is the major reason to use it in my opinion. However, you will see ZS in the app after you finish the workout if you use a belt that measures electrical activity for the heart, not an optical belt.

                                    The algorithm seems to need more development. Below is the ZoneSense plot from 5x hill repeats to max effort on a treadmill.
                                    When running endurance pace I get a steady 142-146 bpm threshold. But no estimate of anaerobic from this workout?
                                    Seems I barely left my aerobic threshold zone 🤷🏽

                                        @Oxhill_Runner the intervals aren’t long enough, from the resources given (and my experience) they need to be nearing 4 minutes long to get into anaerobic range from ZS - although you can see cumulative fatigue building up from the graph.

                                        Steady state efforts and longer intensity is what it’s designed to log.

                                            Another example of the utility of ZoneSense for real time:
                                            I’ve been traveling with my wife and at Sea Level for almost 2 weeks. After returning home to 1600m did a Tempo workout and then a Recovery Run the next day where I felt tired and slow…ZS had me anaerobic at very low HR.
                                            71f653fe-7545-44e7-8339-701715f72bd0-image.png

                                            The next day another Tempo workout where I felt really good. ZS was much different!
                                            68a83e07-29db-4bfc-9cbc-68b20be2669f-image.png

                                            My point is a tool for real time training, I am not paying much attention to my HR zones anymore! Good for longer intervals, these were 8 min Tempo. I would not use for anything less than about 4 min. Most helpful for longer runs.
