Hi all,
I usually get around 20000 steps per day, with 15000-18000 steps coming from morning/lunch/evening walks. On one particular route of 6000 steps, which I have been monitoring for months, I typically burn 200-250 calories (according my Instinct 2). Additionally, everyday for the past few months, my Instinct has told me that I burn around 650 calories total for all my walking activity. However, today there has been a sharp decline in the number of active calories reported by the watch for these same activities. My 6000 step walk this morning gave me around 20 active calories (it's usually 200-220). I've now totalled 16000 steps today and it says that I've burned 150 active calories in total. I've never seen it this low for so many steps. It would normally be at least 450-650 by now (according to the watch that is), as I walk briskly.
Interestingly, there is no colour on today's heart rate graph, but the recorded heart rates are comparable to yesterdays (where a lot more calories were recorded as being burned). The shading of the line is now just a constant grey, with no hot spots that are normally there. I assume this means that, for some reason, the watch isn't registering the same heart rate zones as work anymore, or something. I could maybe understand this over a long period of time, as fitness levels increase, but it's dropped off a cliff today and I'm exerting the same effort when I walk. I've not changed any setting in the watch that I know of. What could be causing this?
Here is what a 20 min walk looked like yesterday:
Here is what a longer walk (on the same track) looked like today. Note that the entire heart rate line is constant grey, and the heart rate is comparable to yesterday:
Any help would be appreciated.
