Lower heart rate on the Turbo.

Okay, so with all this wind and rain I've gone and got a turbo.
I did an FTP heart rate test and was suprised to find how my heart rate is much lower for the same perceived effort. Therefore my zones have all changed, and the bmp for each zone is lower.
Does this mean that any training isn't as effective?
e.g. If I do 20 minutes on the turbo at new zone 3 (145bpm), compared to my road zone 3 of 160bpm.

If your Heart Rate on the turbo is lower then surely you are putting in less effort?0

Heat is the main thing. Secondly the dead spot in the cranks on turbos mean your legs work header as opposed to your heart. Plus I found that in order to get the 175-180 rate I normally get climbing steep hills in real life I had to climb virtual climbs in Zwift chasing someone.0

No - there's more to it than that. But not 15bpm more...0 -
There's also that perceived effort is just different inside. Outside your used to the sensation of your bike moving under you, the road and surroundings going by and how much effort you put in to climb that hill.
Inside, when you aren't moving and your bike is fixed the same work feels much harder.0 -
Interestingly, I find the opposite. For example, my commute home on Monday night (18km into a fierce headwind offset by London traffic and stoplights) generated a TSS of 84.2, NP of 101% of FTP but an HR largely in zone 3.
By contrast, my L4 2x20s the next day generated a TSS of 81.4, NP of 94% (all in, working intervals were 105%/97%), but an HR firmly in zone 5. This has got to be heat, right? Fan setup on the wattbike is suboptimal, by which I mean non-existent. Or possibly a bit of residual shaggedness as the commute in that morning was TSS 75/NP 100%0 -

I was thinking exactly the same when I read the OP's comments.
My heart rate is far higher when I cycle indoors.
When you're outside the wind/breeze calls your body. I turbo with my windows open and a very large fan, yet my body and room temperature with increase significantly, which causes my heart to require extra beats to regular my body temperature.
When you are riding outsider you have many points throughout a ride you are free wheeling or generating less power (micro recoveries). These rests give your heart the time to recover. On a turbo trainer I never stop pedalling and event my recovering power between hard intervals is not enough for the heart to fully recover.0 -
I agree that you generally have more recoveries outside going downhill, and inside you sweat more. However OP is saying that he has a lower HR on the turbo for the same perceived effort. If his HR is average 145 indoors and 160 outdoors, then surely he is putting in more effort outdoors? He may think he's working harder indoors because he's sweating more.If your Heart Rate on the turbo is lower then surely you are putting in less effort?

OP seems to have a turbo Zone 3 and an outdoor Zone 3. I would have thought you would have the same Zone 3 HR band whether you are cycling on a turbo or outdoors?0 -
My HR is lower on the turbo for the same measured power output. Same effort required. Of course PE is higher indoors.
It is what it is. Assuming the OP has a decent turbo trainer I'd suggest using speed as a proxy for power over HR anyway. HR drift tends to influence intervals unless you account for it by making sure you keep HR rising through an interval and not aim for a fixed HR.More problems but still living....0 -
