Hi everyone,
trying to nail down the HR readings problem (using an HRM-Run strap) when accelerating during my runs, I've been doing a couple of runs with both my Fenix 5 Sapphire and Fenix 7SS both receiving the ANT+ broadcast from the same strap. The intent is to discern whether the problems is on the strap or on the watch by looking at both HR readings in case the problem arises again.
And while the problem did not show up (and exact same HR readings, I noticed that for the same run today (a short 37 minute Tempo Run), apart from the expectable differences in the GPS tracks (better as expected on the F7SS), the calculated Training Effects differ. Specifically, it's the Anaerobic Training Effect: it was zero on the F7SS and 1.1 on the F5S which may perhaps be well explained by the fact that I spent 40% time in the HR4 zone.
Surely there's an explanation for that, just curious about what. Anyone any idea?
In the screenshot below you can easily tell the F7 by the richer data (Running Power, Stamina, etc).
