Power Walking - heart rate (and not only) monitoring

Power Walking in Edinburgh
I was asking myself....how does it look the level of exertion on a power walk session? ..in other words: do I cheat or do I really work out well?
I've set up my test on a treadmill at the Pleasance gym, on runtastic app...


I started my research with 10 minutes of power walking at 120 beats per minute (bpm) frequency...it felt quite easy...and the heart rate chart confirmed it: 60% of the time my heart rate was under 118 bpm... wow, this is indeed much too easy, at a speed of 6km/h; still, it felt like a good "warm-up".

Next I got into another 10 minutes chunk, this time at 130 bpm... 84% of this I have exercised between 118-129 bpm, an interval called 'easy'...well...good enough for a 6.5km/h.

And the third 10 minutes chunk....140 bpm...this feels fast...and sweaty..and yes it makes sense, as 88% of the time I exercised in the Fat Burning zone...1.13km in 9.52 mins.
Unfortunately I've simply forgotten to set up the treadmill for my personal details, so the data I have about amount of calories burned it was not accurate.

Now, to answer the question that started my small test: yes, if I am exercising under the intensity that I got to when walking at 140 bpm, I am cheating.

Why would I waste my precious time without achieving some serious 'fat burning' exertion? That's why, next time when I go for my 10 minutes of power walking, I will go straight to my - now proven- fat burning speed: 140 bpm...

Good stuff!

If you want the audio file for 120 bpm, 130 bpm and 140 bpm, just send me an email...

Spring...time to go out!

Such a lovely weather in Edinburgh!
Sunshine, no wind...just perfect weather for a nice walk or power walk or jog or run...depending on your level of fitness...

My heart rate today was constantly on top range of my training interval, which is set up now between 60% - 85% max heart rate...
Power Walking - Beurer feedback

A short analysis shows that for 38 minutes of quite intensive exertion, i managed to burn , according to Beurer, about 324 calories... or about 85 cal/10 mins ...


Another input from Runtastic (see below) suggests 438 kcal for 48 minutes... or  91 cal/10 mins

I would go with an average of  88 cal/10 mins for my outdoor jogging.....

Good to know that my body simply cant burn more than this....so in future, when craving for that muffin of 238 cals, I will no longer fool myself that in I don't know how much gym time (I've never been precise on this) I will burn that out completely....

I hope this monitoring to be a way to educate myself about the limits of my body, so I become aware that if I want to maintain healthy weight, I must pay attention to how much I put in through the food I choose...

I will try to keep a kind of a food diary too....that's difficult, huh?
