Calculating Max Heart rate
Comments

What you said, was its "Faux Science", which suggested you were well read on the subject and had concluded the studies which involved more than 5,000 people for over 3 years were scientifically flawed.
I didn't say the study was flawed. But I did suggest that your interpretation of it might be. Is it NHS policy to refer yourself to your GP if your HR recovery is <20bpm? Yes or no?You are aware that NHS guidelines suggest you go see you GP if your HR is regularly below 60bpm. I think I'll ask my GP for a deal on renting an office in his surgery.
What seems to be missing from all of your comments on this thread is something called 'context'....look it up..0 -
Why don't you read it and form your own opinion? You might also like to look up why doctors prescribe ETTs exercise tolerance test and why those tests monitor exercise recovery rates. It seems bizarre to suggest someone's interpretation of a study is flawed without first reading it.
I did actually find quite a lot on ETT data analysis, but can't see why I'd post it for it not to be read.
To turn your question in to a more useful one:
Q: if my heart does not recover, post hard exercise at at least 20 bpm in the first minute am I at a greater risk of mortality due to a heart problem? A: YES0 -

Care to share your source on that because NHS choices says contact doctor if HR regulary under 40bpm.It also points out this could be perfectly normal especially for an athlete.0 -
That's what I mean by context

Since this is already a thread about MHR and it seems pointless to start another:
My MHR is 195 (actually the highest I have seen more than once is 194 but I once managed 195, I figure it's such a small difference it doesn't really matter). I know this through conducting MHR tests (TCTP protocol), Sufferfest, my HR when I'm getting dropped in chaingangs, all out efforts on short hills, etc etc.
At the moment I have a cold. Not a chesty one (yet), but bad enough that I'd not normally go out. However last night it was sunny and it was also the last time I will get to cycle until at least 22nd October so I went out anyway. Standard ~30km loop I've done dozens of times, went with a couple of friends. There's one short hill (1'20" - 1'30") which we always go all-out up, I wasn't going to because of the cold but I got a bit carried away...
Anyway I looked down at the top and saw 202bpm on the Garmin. Looking at the file it wasn't just a momentary blip either, I was apparently over my MHR (or what I thought my MHR was) for a good 30s which is surely impossible.
So is this a) an error with the HRM or b) something to do with being ill? Is there any mechanism for MHR being higher when you're ill??
I can't think of anything else different about this one effort that would have resulted in such a big increase in MHR apart from the cold. It certainly felt no different to any other MHR efforts I've done!0 -

But before I get accused of scare mongering with more faux science
- I've also heard it can effect the ability of the blood to carry o2 and also that your metabolism will raise to fight the cold.
I've always found hitting some exercise is a great way to beat a cold, but I'm told its just a temporary high and that the cold gets worse if you push your body when ill. I'm inclined to go with the latter version.
I personally find your resting HR is a good indicator of where you'll get to on a day in terms of max. Depending on the time of day and what I've eaten, my resting is mid-30s to high 30s occasionally low 40s. I know I won't get much higher than 173-175 if it was sat at 34 only a 20 mins earlier. On the other hand if I stuffed my face 1 hour before I'll get above that without too much effort.0 -
I don't know exactly but it's often mentioned that your MHR for cycling will be different for you MHR for running so your not actually finding out the Highest heart rate that you body can produce but rather what the highest is for that form of exercise. I beleive it is usually slightly higher for running because of the extra work of supporting your own weight. Perhaps your cold had a similar effect.Since this is already a thread about MHR and it seems pointless to start another:

While obviously an MHR effort is always rather unpleasant, I've never had actual physical pain from it before or this time (certainly not in the chest), nor have I had any of the other symptoms listed, so hopefully it's not that. Except maybe fatigue and weakness, but if you don't feel fatigue and weakness after an interval hard enough to hit MHR then surely you haven't done it right?? . I felt fine after I got home anyway.
The raised metabolism explanation sounds relatively reasonable. The rest of the ride was pretty sedate (only 24kph moving average) so I've really only got that one climb to look at. I got into my normal Z4 a couple of times on climbs, but nowhere near MHR - my max apart from that was below 180 (looks like about 177, and not sustained either).0 -

The link you have posted is in relation to a specific condition.Atrial Fibrillation. It advice's to contact your GP if your HR is consistently under 60 were as the figure given for a resting HR is 40.I suppose the best advice is to seek medical advice from an expert if there is any doubts.0 -
The answer is that your max heart rate is higher than you thought. It is at least 202 rather than 195.So is this a) an error with the HRM or b) something to do with being ill? Is there any mechanism for MHR being higher when you're ill??

Hmm. I'm not sure about that. If it had been a beat or two higher then yeah, but as I said I have done actual specific MHR tests (which is what you're supposed to do to find out your real max, according to everyone in this thread...) more than once and never got higher than 195.
When I get the turbo set up again I'll try another MHR test and see what happens.0 -
As I mentioned a few posts up your MHR for cycling is always actually slightly lower than your real MHR which is why triathletes will have a higher running MHR than they do for cycling.0
