A year ago, a one hour rowing session would burn 120 more calories than it did today.
How's the work being calculated?On my fitbit.
As you get fitter, you should be able to perform more work per unit of time.[
I have to pace myself on an hour long session - I want to be able to make it to the end! So it's likely I'm not going as hard as I could, although I'm covering more distance (as calculated by the rowers computer).
The fitbit's using HR & weight presumably?
The "more work" question I suppose comes down the whether the greater distance travelled more than offsets the lower mass being moved (or maybe the distance cal already takes account of mass?). My strong guess is that for a given intensity of perceived effort you'll be doing more work, ie burning more calories, now than when you began and were less fit, and that the fitbit number is misleading. One of the bonuses of getting fitter (become more powerful) is being able to burn more calories in a workout.
This is the standard pattern seen with bike turbo trainers (where the work done can be measured accurately via a power meter rather than relying on a proxy like HR with lookup tables).
If you have access to a time machine then you could do a 1hr test on your mate's C2 (if that's got power measurement?) back when you were unfit and compare to a similar test now!
