Is there any benefit to me wearing a HR chest strap when using my turbo trainer? Or shall I just wear it when I’m outside (and without power meter). Thanks

That’s great.
same comment to the other thread, I stopped wearing mine. I didn’t see any value in the data.
For me I want to record VO2max (or at least an estimate of it) and my Garmin won’t estimate VO2max without HR. I also like to see that HR is matching up with power so I know what to expect on road and its reassuring to see that recovery/ endurance sessions also coincided with a Z1/2 HR. I’ve never done it but I think Id call it a day on a recovery session if my HR was stupidly high (I think Id be doing more harm than good there). I also like to push in VO2max sessions beyond the power zone and get above 90% Max HR.

Some apps use HR to calculate various workout/fitness metrics. Strava for example uses it to calculate Relative Effort and Fitness & Freshness tracking. Garmin uses it to estimate VO2 max, lactate threshold, FTP. The usual explanation is a power meter shows the power you’re outputting and HR shows how hard you’re working to do it. e.g. An atypically high HR for a given power level may suggest overtraining. In end it boils down to how you utilize this information in guiding your training.

I’ve always found it useful. It lets you track decoupling which I find useful during training. And during an event it can give you early hints about heat stress and fueling. Power is what you’re putting out. HR (and RPE) are about how your body’s handling that.
HR during an effort is also used by TR for adaptations and FTP estimates. There are a few old threads about this.
I personally went through a phase where I’d stopped recording HR on the trainer because I was lazy, and AIFTP tended to underestimate my FTP by about 5%… till I started recording HR again.

I would be curious if TR really does use HR data from indoor workouts. Part of the reason I stopped was I had a series of issues with HR straps. I went through 2 Wahoo Tikr’s to Polar H10 trying to find a set and forget strap (other than batteries), but had continual problems, no readings, low readings, constant dropped readings, the data was crap, so I just ditched it and never looked back.
They do.
What am I losing if I stop tracking HR? - #4 by eddie?
>We do use heart rate data in AT (Adaptive Training) and AIFTPD (AI FTP Detection) when we have it.

It good so you can look back on your training history for any trends if you look for that stuff.
Also if you ride off road, say CX where power is all over the place, heart rate comes more into play.
I wear one for outside and inside rides primarily to notice any anomalies that might indicate fatigue or illness. For outdoor I was use it a bit for endurance rides. After I had covid and also after a shingles vaccine my coach noticed my HR was too high for the workouts I completed even though I felt fine so she actually adjusted things to allow me more recovery

HR is needed to track efficiency and decoupling and is a good indicator of fatigue.

Thanks… sorry I should’ve been more specific… benefit to TR algorithms, I don’t look at the HR personally and don’t have a coach.
Bit confused. The comment you’ve replied to directly states HR is used in the TR algorithms.
When I inquired about this last year, the answer from TR was that they don’t use HR. IDK if that’s changed.
I like it for endurance rides where I can target say 70% of max rather than focusing on a power target, which I find more tedious over 2 or 3 hours.

Exactly … I meant thanks for the answer, it was answering my query

I like my yearly average HR/km metric
If you are doing VO2 efforts, HR helps you see if you’re hitting the right level of intensity, and how well you are recovering from each set. For instance if you are only reaching 80% in a set then perhaps the intensity isn’t high enough. Alternately, combined with heart rate recovery, it may indicate you are over fatigued and need to bin the session or either do something much lighter or rest.

The power meter shows how many watts you are pushing. The HR monitor shows your body’s reaction to that. Both are important information.
