  • How do I figure out my true (err on the side of safe) max heart rate? I’m not an athlete. I regularly exceed 175 (220 – 45yo). I just did a 20 minute functional threshold performance test on my peloton. I was definitely huffing and puffing at the end. My heart rate reached 187 and my breathing rate was very high at 59 while my max heart strain was…Read More

    • The 220 minus age formula is next to useless. For example, I’m 60 yrs old with a max HR of 196, yet I know others my age with 160 bpm max.
      I’m not able to hit my max HR during 20 min critical power test, that requires a shorter, more intense effort. So I would imagine your Max HR is still going to be higher than 187, perhaps by as much as 10-…Read More

  • Thanks for the device it’s quite reassuring.

  • After work outs, when I view the graphs for analysis, I always notice a faded grey ish vertical line on the graph and I don’t know what that means? Is this just me or do anyone else see the line?

  • Hi,

    • The value shown as ‘ Effort’ during your activity is the same as your breathing. You will notice that the unit for this value is breaths/min. We are using breathing rate as a measurement of effort because there is a lot of research to show that breathing rate is more closely correlated with perceived effort than heart rate.

  • Can I get the ECG data from a recording into a program that will analyze the rhythm abnormalities precisely like a Bardy or ZioPatch?
