10K Cut Short

The heart strangeness happened before the last work interval. Heart rate increased before I started working again (first green arrow on the left) and then after I started working to increase the pace, heart rate slowed down. After I stopped working hard, heart rate increased again. But it seemed normal by the end of the session.

Today’s main workout was supposed to be 10K on the rowing machine but it had one falst start and finally got started too late in the day to finish it in a timely manner before dinner.

Before rowing, I did 143 calories of alternating work/rest on the SkiErg (see screenshot, above). The SkiErg session went well except there was a wee bit of strange heart behavior near the end, when heart rate started to rise before I started the last in a series of work intervals. But heart rate seemed to return to normal by the end of the SkiErg session, so I put it out of my mind.

Next, I set up a 10K session and was intending to include 8 intervals of 500 meters each, spread throughout the 10K. But heart rate became irregular, so I got annoyed and went to take an aspirin. To buffer the aspirin, I had something to eat. The rowing workout resumed quite a bit later and there wasn’t enough time to finish it and be back to normal before dinner time, so I limited the 10K to about 4K and quit.

The first attempt at a rowing 10K was cut short after only about 500 meters.
There isn’t much of a graph for the first attempt at a rowing 10K today, but you can see that heart rate display was zero for quite a bit of the time during that 500 meters. When heart rate is zero, that usually means heart rate is too irregular for the heart strap to transmit a readable signal to the rowing machine monitor.
