Hi,
I'm playing Squash but unfortunately it does not exist in the Garmin world, so I had to select other activities to record my games.
I noticed the heart rate measure on my Vivo4 is very dependent on the activity I select compared to a chest belt and the record of the hear rate with my phone during Squash (which is i guess difficult to track due to high hear rate and quick variation while playing and between playing and resting between games).
If I select Cardio as the activity, the Vivo4 reading, and heart zone % are reasonably coherent with what I got with the belt. The Vivo4 does not capture the quick increase of HR during games or decrease of HR during rest very well, but I would say it's usable, see figures recorded yesterday:
Belt : Average HR: 136, Max HR: 162, 33 % in Zone 5, 44% in Zone 4
Vivo 4: Average HR: 136, Max HR: 158, 22% in Zone 5, 63% in Zone 4
If I select another type of activity, like Running without GPS or Running Indoor to measure my activity during Squash, the HR measure and Zone % are much lower and completely off compared to the belt and not usable, see figures recorded today:
Belt : Average HR: 133, Max HR: 171, 29 % in Zone 5, 37% in Zone 4
Vivo 4: Average HR: 120, Max HR: 139, 0% in Zone 5, 13% in Zone 4
I got the impression the HR real time measure is smoothed off and peaks averaged to remove what the watch considers as glitches, but the end result is that it's way below reality and inaccurate for Squash.
I think Garmin should investigate this and propose a solution.
How do you submit a bug to support ?
