Today was a deliberately low-energy rowing day, as most days have been since I began the “detraining” in January of this year.
The day’s workout time was divided into 9 sessions totaling 11,490 meters, which is the current minimum daily quota. The main session was not the longest but it was at a degree of higher energy than most of the rest. It was 4 minutes rowing with a target pace of 1:58.7. I overshot the pace a bit and ended with an average pace of 1:58.6.
I didn’t anticipate that the pace of 1:58.7/500m for a mere 4 minutes would bother my heart, but it seemed to be the trigger for a few hours of atrial fibrillation. The Afib cleared up a few hours later when I did about 20 minutes of easy rowing to finish the day’s workout quota.
If you look at the red line for heart rate in the screen shot of the graph (below) for the 4 minute piece, you can see that heart rate wasn’t charting where it should have been. Atrial fibrillation seems to confuse the electronics of the heart strap and make messy, non-sensical heart rate graphs.
If you are curious about any of the other workouts I’ve done since the previous post on June 4th, all data and “live” graphs can be seen via this: link to the online logbook.

Happy rowing to you!
