Right,

Here goes.

Age 47, so max exercise heart rate should be 220 - 47, say 173

Now, having recently bought an hrm and used it a fair few times, it tells me that my average HR is about 147 for a one hour moderate exercise, but the odd hill or two sends it to 185 or so (I've set it to bleep at 170).

Now, this whole HR and exercise thing is quite new to me and the first time it started bleeping away I got rather concerned. The question is, over times (a newby here), does HR reduce as you get stronger/fitter and as I progress will I see a lower rate for the same output effort?

My resting BP is about 110/65 and rhr at 60bpm.

I'm just a little worried that though I don't feel particularly breathless, at the higher rates I might be doing myself harm. In essence, i'm, kinda asking where the limits are HR wise.

Cheers.

Sounds ok to me - Sometomes the HRM can have a blip. I'm similar age, and last year the HRM started bleeping madly when I was going uphill, and was reading 190 or similar. I screeched to a halt and manually checked my pulse, and it was (not surprisingly) a lot lower. I guess these are a guide, and most of the time pretty good, but get upset with the signal sometimes - It seems to happen more in cold weather, I guess less perspiration/poor contact. If it goes really mad. you're not dead 'cos you know it's happening rofl

Buy some of this and smear a thin film over the sensors.

Im no doctor so if your worried get checked out but I'm 41 and have seen 198bpm on a few hills this year.

The last 5min of my FTP test was over 180bpm.

I wouldn't take it too seriously. I used to worry about this sort of thing but started to realise that even though it was bleeping like mad, I still felt like I could exercise a lot harder and would have done if I hadn't known I'd hit my MHR.

The whole MHR calculation isn't very scientific either. I'd just use it as a guide to get you in the right zone if I were you.

Completely ignore 220-Age. Approximate at best. Some will struggle to reach that, some will exceed it easily; your heart didn't read the equation. That said, if it 'spikes' at 185, it's maybe a strap / conductivity / nylon shirt issue. It should rise steadily to that, and descend steadily after.

In terms of establishing training zones, establish your real max HR, your resting, then work the zones from there.

Oh, and yes, as you get fitter you'll need less HR for the same effort - or more likely you'll go faster for the same HR!

HR increases as a result of oxygen debt in the muscles. Oxygen debt is caused by not enough oxygen in the blood being delivered (obv), so if you work hard your body needs to either pump more blood in a given time (more beats), or get more oxygen in the same amount of blood per beat.

Simply increasing the number of RBCs means the same volume of blood carries more oxygen - and over time this is your body's response to being asked to work hard. And as you increase that number, the heart needs to pump less often to deliver the same amount of oxygen.

Your max HR is best not calculated but what you have recorded as a maximum (excluding any erroneous figures) and then work out zones from there.

Just pedal the bike and don't worry! - All these things are really garbage just aimed at taking our money. Having a cynical day today.

I'm 48 and mine occasionally hits 215 when I'm working hard, am I going to die?

Resting pulse is about 47 and I average at least an hour of exercise every day...

It hit 215 on the flat today which could have been when I was going north of 30MPH or more likely, as I re-rode the route of yesterday's crash.

A dollop of licking and once out the sweat keeps it in contact

It is, previously I had erratic readings, since using this stuff it has performed perfectly. I can't recommend it enough, for the price it's worth a try at least.

Using saliva only works so far, this time of year it is useless, when warmer it would dry between the time i got dressed and starting riding meaning i would have to use a wet finger to rub on the sensors - and still get spikes.

220 - age is only a rule of thumb, individuals vary. I wouldn't worry about those numbers if you're feeling fine.
