Zwift Chat

On the subject of heart rate monitors... Q: Most heart rate monitors will probably be the chest strap type, but do any of you use smart watches to do the job on Zwift? If so, are there any fairly decent suitable smart watches that are not extremely expensive? [I haven't researched the subject at all!]

It's hard to see because although they are reseeding, they are also recalculating all results since 25 Sept. All that will have an effect.

They also said it would take a couple of hours, so maybe you're looking at an interim result? Mine hasn't changed at all yet. Still 541

Just checked mine, no change either yet

I see another shoot storm on the cards 🤣🤣

So do I. Someone's already reverse-engineered the new seed formula and the result, if correct, is not going to amuse people.

For me wrist watch HR feature is totally unusable. There is upto 70bpm error. Forearm or upper arm straps seem to work ok. Best obviously chest

Same as that. For 24hr monitoring it's fine. For activities involving movement, it's garbage.
To my mind if you want an accurate figure, a directly measured electrical signal from the organ in question is going to trump shining an LED on your skin and doing magical calculations on the measured values of the reflected light. In all honesty I'm amazed photoplethysmography works at all. But they do use it in hospitals for pulsoximetry.

In a January i go to hospital for a physiologic test and catheter ablation. That is concerning my arrhythmia symptoms.

I can only rightly assume, Zwift can see some deep hidden talent

Okay, that's that then! (And it saves me wasting even more money on tech that I don't really need... )

Yikes - good luck with that!

I might end up with that too, but at the moment the rhythm problem only flares up if I really overstress myself.

Agree, sat still, sleeping the Garmin watch works well. Activity, nah

Kinda admire the chutzpah of this



This guy had stopped about 3 feet short of the line when I passed him. Subsequently waited another 10 mins or so before rolling in last 😂

Works a bit better on nailbeds (unless someone has nail polish!) but yeah I find watches reasonably good at normal ranges but whenever hr spikes it's miles off

Q: Cheapest reliable chest strap HRM?

Q: Cheapest reliable chest strap HRM?

Only ever bought one: Garmin Dual I believe it's called. 3 years and still holding on.

Aha! A revised score of 496, still shown as a 'B' but I'm guessing that's 'proper' C territory?

They're not quite finished yet.
