FTP testing and HR response

doulos

I posted this on Wattage and got no replies. Hope someone can help.

For those with significant testing experience what does an acceptable
HR as a %max or %AT profile look like for what you would consider a
good effort during an FTP test?

Thanks Tim

Alex Simmons

I'm not surprised there was no response. Does anyone still wear a HR strap anymore?

If you're doing a FTP test, then what does it matter? You either went as hard as you could and paced well, or you didn't. Your HR won't tell you either of those. Look at what the power meter tells you.

Thanks Alex. I expected that but was still trying to figure if HR data is useful at all, either on the road or in the post ride analysis.Appreciate your thoughts,
Tim

It may have its uses, but I wouldn't consider pacing an FTP-test effort to be one of them.

Just to provide a practical example or two of how it would be really difficult to use HR to guide pacing. I doubt I have an example I can easily track down of a session where HR was held steady to see what happens to power - but I think you can work out what would happen....

Here is an image of power (yellow) vs HR (red) during a 2 x 20min interval session:




Here is an image of the same thing during an hour long hard tempo session:

I use HR to pace indoor 3x20s I haven't used it to pace a 1 hour TT but my average was 162bpm when I was done. This leads me to believe 163bpm is my threshold HR and 164bpm is above threshold my MHR is 185bpm age early 40s. Some days my legs won't let me pace by HR it is a fuzzy guide.

Alex....nice pacing on those intervals! That's the way to use power....start off a little below and finish strong....

It's not me.

… I don't know my FTP (will know soon) However if an average for a 1 hr TT will give you your FTP then the equivalent in HR would approx. 86-88% of MHR. This fairly arbitrary as MHR really needs to be found by going there and even then will vary as you age and as fitness levels change.

… according to the 220 less your age nonsense this for me would be more like 95% of MHR

The problem is that it's highly individual, varying from person to person, not to mention other variables that influence HR (such as the drift Alex beautifully illustrated above). If HR were that concrete and stable an indicator for exercise intensity, we wouldn't need power meters in the first place.
