It's a wrist based one, and I do struggle to believe it can be all that accurate, but I've checked it at rest and it does seem to be very accurate. Can't swear that it remains as accurate when I'm running of course.
I've never paid any attention to heart rate before, but part of my logic was that maybe I feel like I'm at maximum effort but I'm not? I only run 5k, am overweight (but losing) and until 6 months ago I wasn't really doing much exercise, so I suppose I don't really have a frame of reference for 'max effort'.
Having run again today, I spent 87% of the run at or above 90% of my supposed maximum. I think I might reset the ranges...
Following a previous post here about trying to increase my pace (but being scared of pushing it too hard) I have bought a garmin watch. I took it for its first run today, and I have lots of lovely graphs to show for it...
but the heart rate...so, at 41 (nearly 42), my supposed 'maximum heart rate' would be 179 by the 220-age formula. But i don't really know what that means. Does it mean it's in some way unsafe to go over it? It certainly isn't my maximum heart rate. 72% of the 5k I ran today, I spent at 160 or over ie at 90% or more of my 'maximum heart rate'. The maximum recorded was 190, so again, a good bit higher than the theoretical 'maximum'.
So, my question is, is this 220-age formula just to work out what your maximum might be if you don't know? Or does it actually mean something? Is it dangerous to go over it? Or is it nonsense and my maximum is just whatever my maximum heart rate actually is when I'm running? And I should calculate the % ranges based on my actual highest heart rate?
A final question...I bought the watch largely because I thought i was perhaps being a bit lazy and not pushing myself hard enough. If my HR is in that 90%+ of 'maximum HR' zone for most of my run, does that mean I shouldnt be pushing myself any harder (till it comes down)?
Thanks for all the advice. Think I'm going to get one of these garmin thingummies..just need to decide which one.
A parkrun pacer sounds like a great idea. We definitely don't have them at the parkrun I do though, and there's only one other parkrun nearby and I don't think they do either (although I'll check). I've a good idea of what pace I need to aim at for now though, so the garmin should help with that.
Hhmmm one of those watchy things looks tempting. Will they all buzz at you (or whatever it is they do) to tell you to speed up?
Supernoodle - yes, it was after today's parkrun that I was thinking that I really probably could put a bit more effort in to be honest. It's too easy to plod along at the back. I do run it with my 8 year old, but I know from him running with his dad that it's not him holding me back!
