I don't know about the accuracy of calorie burn (although I assume a HRM is more accurate than most other measures of how hard you are working, like the machines in the gym for example or the MFP database)
I use a Garmin, actually I usually forget to put the heart rate part of it on but the idea was to use it to train within the 5 running zones - so Recovery Runs are at 50-70% of maximum HR (there's a one size fits all formula based on age or you can work it out individually from your resting heart rate, which goes down the fitter you get but your max stays roughly the same I think) and then: General Aerobic/Easy 62-75% Long 65-78% Marathon Pace 73-84% Lactate Threshold/Tempo 77-88% VO2max (5k pace) 91-94%
it's not been amazing for me because my heart is like a galloping horse inside my rib cage whenever a car passes me but I use it in the gym sometimes
I just like collecting the data really, whatever incentivises you has to be good?
I have the polar FT4 and its brilliant. I do have a cheaper one, a sportsline solo which was slightly cheaper but to be honest, it's crap and very inaccurate. You do need one with a chest strap to moniter your heart rate. The machines at the gym are crap too, again very inaccurate.
Polar are brilliant, mine was about £60 but worth every penny as it keeps me motivated.
Combined together those create a graph when you do an exercise wearing both devices.
When wearing just the band, it tracks number of steps.
Not sure how the pictures will turn out... one is a graph showing heart rate during a spin class, one is the calorie detail for that graph, and one is the step count page for a day when I did not do any class but did go walking in the woods with one of the children for whom I care.
Note that the VivoFit does not link to the bike, so does not get correct reading for Distance, Speed. Not entirely sure if the calories detail is correct. So for calories maybe the bikes own computer unit would give a better indication.
Just started with VivoFit so still exploring what it does. Anyone have one and know how to set it up so it tracks a spin class calorie burn?
In this picture is a Heart Rate whilst doing a BodyVive class, so it should have also step counted more accurately.
I don't know about vivofit or other activities but in garmin connect for any given run you can click on 'view splits' and then scroll quite a long to the right and see the calories per mile and calories for whole run. hope screenshots work.
you can make them whatever you want, mine are in miles
it does work without GPS (this is the 220, don't know about others) I've switched the GPS off to use on a treadmill before and in an indoor swimming pool - I don't know how it works, that motion sensor thing, there's no foot pod
I bought I wristwatch style HRM off eBay for £6. It is shit. After finishing a 6k run apparently my HR was 77bpm. And I had to hold my finger over a sensor (I foolishly thought it would take the reading from my wrist pulse, dur). So anyway you get what you pay for. I am now holding out for the Samsung Gearfit.
