Discrepancy between HR vs Nose breathing

    Hi all,

    I’m on week 7 of transition and I’ve begun to run more vs power walk/run.

    What I’ve noticed is …though my suunto HR watch with chest strap says 150bpm…I can still nose breathe. So I usually also down…power walk …for literally 10-15 seconds…then start again…and on and on I go…

    Is this an issue with my HR band?

    The other night I had my monitor buy ignored it…instead just running and checking once in a while my capacity to nose breathe and if I could do that I simply kept going.

    I don’t want to be negating any effects of zone 1 training by thinking I’m okay with nosal breathing when in fact I’m ignoring the HR band and and am in zone 3+

    I think we need some more information. 150 BPM is high for some, low for others. Have you tested your AeT?

    It IS possible to nose-breathe above AeT. This can happen if you don’t have a gradual, thorough warm up or if you suffer from ADS.

    I am deferring to the Scotts, Steve, and company for the physiological question, but I wanted to chime in about similar issues I’ve had with the Suunto HR strap. I’ve used Polar models for years with consistent readings so I have a pretty good idea about what my HR feels like various levels of exertion. I used the Suunto strap after getting a Spartan watch but into a few months of use I got extremely erratic readings. I got in touch with their customer services folks but the problems persisted.

    Ultimately, I switched back to a Polar strap because of the reliability.

    In any case, good luck!

    @Canada:

    As Scott S says we need some more info before making much progress on your question. Be advised that nose breathing (conversational pace) is “good” predictor of AeT for “most folks”. That said and as Scott mentioned. If you have ADS all bets are off and nose breathing may be way off. I’ve asked numerous physiologists and no one has given me any kind of decent answer as to why ventilation does’t work well in this population. That is what we offer the HR drift test an another and more universal test for folks to use https://uphillathlete.com/heart-rate-drift/

    It is also important to bear in mind that both the AeT and AnT/LT move around from day to day based on recovery state. They are not static.

    @Izzy
    I’ve found Polar straps to consistently be better than Suunto or Garmin. The old snap on/off Garmin HR monitor will snap right on to a Polar chest strap.

    Usually a faulty strap give crazy readings that are so wrong you know something is up. I’ve never seen one that was a few beats off consistently.
