VO2 Max

my chest strap is about 13 months old and exactly after 12 month I’ve had to replace the battery.
It stopped working from one day to the other.
I’ll try and observe today again with a merino shirt.

it surprises me that you and @cosme-costa don’t have issues like that with synthetic shirts, I thought this was one of the main reasons why we see these spikes

I use the VO2max value only as a reference for myself to understand if I am better or less in shape than in the past. The actual value itself doesn’t tell me much.
But I also made the experience that it is jumpy depending on the topography or how fast and far I am going… so basically, I could as well ignore it

@freeheeler I’ve never had those spikes with a working strap. Did you put yours in the washing machine? I once killed one that way. Current one is one year old, I had to replace the battery at some point last year, but it’s working well.

No, I never put it in the washing mashine. I wash it by hand only.

@freeheeler and you probably know, but worth repeating, if you completely wet the strap under the tap in some water before putting on it can help to eliminate some of that electrostatic discharge. It’s why usually after a while (you sweat) it helps.

Always hard to put on a wet HR strap though in the morning

@marcw
yes, I know. I’m wearing chest straps for over 4 years frequently now.
Hence I am going to order my 5th strap today… I really should start tagging the activities when I notice the strap is dying…
I remember that the newer strap should have been improved, but I can’t tell what’s been improved since it starts giving crazy results after one year, just like the straps before

it’s not hard @MarcW, no harder than putting on a dry strap… Might be uncomfortable, that’s why I wet with warm water.

@MarcW
slightly moist contact pads have been sufficient so far… I will for sure not put on a completely wet strap when preparing for a day resort skiing
