Suunto ZoneSense

@tschogo that’s the point why ZoneSense doesn’t work.

It seems you are in a minority here. I have had laboratory tests as well for AT and LT and VO2M. ZS does a good job with those values when I feel great. On days when I am fatigued ZS does a great job as my set HR values are incorrect. I find ZS invaluable.

I have a substantial aerobic base having run ultramarathons for 14 years. I have a good idea of my max HR, you will not hit MaxHR on a Cooper test as the test is too long. Short 1-2 min all out uphill intervals will likely come close to your max HR. I suspect your HR zones are off and ZS is likely interpreting your efforts correctly.

85% of my HR max is anaerobic at 153 but nowhere near my LT at 163. I would run a Cooper Test at above my LT at 90% or more of my max HR. My last Cooper Test was 168 bpm avg for the 12 min test and ZS nailed my LT in fact, higher than my test.

PS I am 68.

@Sportsfreund I am interested how Zonesense works for you in rowing.

I never rowed on water, only on ergs. For me Zonesense delivers plausible feedback and helped me to fine-tune my zone settings.

My intensity targets come from EXR where I regularly perform a ramp test. What I found out by now is, that my zones in running differ from the zones familiar to me from running.

@Sportsfreund … or you’re just way fitter than you assume ! Actually one of my trainingpartners for the II. Dan training was an ex russian rower (quite on pro level) and then in his late 50s this guy was extremely fit and could actually train for hours without appearant signs of exhaustion.

Very interesting to read. I think Suunto needs to address this more clearly in their ad/description for ZoneSense. With this I mean how crazy widespread ones AT can be on a daily basis (on a HR scale). To me, not being any sport scientist at all, it still feels crazy, that on one day AT can be at 140, the next at 160. But I‘m very curious to see where this journey goes and will use ZS on all my upcoming trainings.

Mine vary as much or more than yours! I believe this is the power of ZS! I train primarily by RPE and ZS is scary good at matching my RPE. On days I feel even a little tired my AT has tanked according to ZS. I am primarily using ZS to keep my Endurance and Recovery runs easy enough.
