@Doodoo-Runner said in Suunto ZoneSense:
@sky-runner this reviewer did lab tests along with ZoneSense . Among his group was DC Rainmaker. The findings suggest Zonesense is not to be trusted.
curious to know why, with the same HR source, the SV and SR results differ.

This reviewer did a lab test along with ZoneSense and came to the conclusion that it’s very good:

Just to show that in today’s world of influencers it doesn’t take long to find someone who claims the opposite.

@Brad_Olwin I agree - it’s the real time feedback, that is most valuable and for me too it really corresponds on how I feel. I used to train a lot by HR Zones and sometimes it worked great but often I felt they were too low to or too high compared to my set zones (having had a tested LTH).
With Zonesense this feels much more ‚realistic‘ and actually Zonesense for me is (besides others) one of the features why I would never use another brand. -
@Brad_Olwin I don’t really get what you want to convince me of. I am just stating scientific facts and want to point out that the accuracy of ZoneSense is just based on anecdotal information like yours and that the scientific data rather hint to a too high inaccuracy to recommend it for training control on a population level. Therefore, users with strange data should not be unsettled that they do something wrong in their training.

Is it possible to turn Zonesense off in the app (iOS). I do not use it. Unfortunately it set default in the graph.

@MarkusG big problem of our modern society where everyone can just spread unverified and anecdotal information! Better rely on verified data from independent researchers and experts. But apparently there is too much money to make with just claiming that you have developed something special. Garmin is the worst example with their “body battery”, “heat/height acclimation”, “Real-Time stamina”, “endurance score”, “training readiness”, “running tolerance”, “race predictor”. Nothing of that has ever been scientifically validated that it actually works and every good coach and athlete can do more accurate race predictions
