Though there was nothing posted yesterday there were eight sessions done on the 14th. They were all on the rowing machine. Today there were five sessions done and they were likewise all on the rowing machine. Their graphs and data are available at this link to my online logbook. They will be the log entries with the date of the day’s sessions you wish to look at. See their data & graphs by clicking the corresponding “+” signs in the “Action” column.
There was atrial fibrillation yesterday and there has been all day today. That was one reason why I only used the rowing machine: because I can log more meters in less time at a lower heart rate by rowing than by using the SkiErg. The SkiErg has not been abandoned – just omitted for a little while.
Altogether there were sixteen mostly short sessions done today. Their graphs and data are available at this link to my online logbook. They will be the log entries with today’s date. See their data & graphs by clicking the corresponding “+” signs in the “Action” column.
There was no atrial fibrillation detected after mid-morning today – hooray!
On Tuesday, February 11th, I did relatively little on the ergs and on Tuesday I also “went into hiding” from the blogosphere and didn’t post anything to this blog.
It didn’t help that there was atrial fibrillation all day yesterday. And all last night. And all day today.
But today I felt the urge to emerge, so here is a blog post.
Altogether there was 28,802 meters in the sessions done yesterday and today. Their graphs and data are available at this link to my online logbook. They will be the log entries with yesterday or today’s date. See their data & graphs by clicking the corresponding “+” signs in the “Action” column.
Today’s main workout session was a slow 10K done on the rowing machine, with many interruptions.

Since the Garmin chest strap supplied mostly a flat line for the RowPro heart rate graph, here is the heart rate graph from the other heart strap (A Scosche optical strap).
This cat must have gotten a good workout because it’s sleeping well.
Today I was shy. The original goal was to do a total distance of 42,195 meters by breaking it up into shorter distances. But after rowing 10,000 meters shy of marathon distance it felt like I’d done more than enough to sleep well tonight so I called it quits for the day.
Altogether there was 32,195 meters in 8 sessions done today. Their graphs and data are available at this link to my online logbook. They will be the log entries with today’s date. See their data & graphs by clicking the corresponding “+” signs in the “Action” column.
Today’s data from a Garmin heart strap reminded me of a “cwazy wabbit….”
There were a total of seven workout session segments today. None of them were very long. The longest was 7,000 meters while rowing.

If you look closely at the RowPro-generated HR graph for the 7K, you’ll notice that it’s kinda crazy. Slope of the graph is descending though pace is fairly constant and rate is “impossibly” low for the effort level. It was graphed using data from the Garmin chest heart strap. The green-on-black graph below it looks totally reasonable so it was probably correct. It shows HR in normal range throughout the 7K. It used data from a Scosche optical heart strap. The Scosche is worn on the arm and I call it an “optical” strap because its method of detecting pulse relies on monitoring changes in the amount of reflected light instead of monitoring the body’s electrical current through the heart.
There was no atrial fibrillation just before, during or immediately following today’s rowing; therefore the weird Garmin HR graph was caused by something else. My guess is that it was averaging the strongest periodic pulses recognized by its algorithm and the heart was on the brink of atrial fibrillation, generating pairs of pulses instead of single pulses for each beat whose phase relationship did not remain constant.

Today’s title relates to the “detraining” approach as a remedy for atrial fibrillation. AF was happening before, during and after today’s workouts so when it was time to do the customary daily 10K rowing, it was done even more gently today.
Altogether there were nine workout sessions today. They were all short except for the 10,000 meter rowing session which was a bit longer than any of the others. You can see the graphs and data for any of them by visiting this link to my online logbook, looking for log entries that were made on today’s date and clicking their corresponding “+” signs in the Action column.
This particular Garmin heart strap only works well if heart rate is normal and chest is sweaty.
Today’s main workout was 30 minutes. Overall time and distance was less than yesterday but was more than 10K meters.
There was interference from atrial fibrillation and though I tried salty paste on the Garmin heart strap again today, like yesterday, it didn’t seem to make any difference. Atrial fibrillation overrode any benefit from better electrical conduction between chest and strap.
In addition to the 30 minute piece there were three other sessions. They were shorter, on both SkiErg and rowing machine.

The paste in this picture is not the kind of paste I used today.
Today’s main workout was 10,000 meters rowing at a steady pace averaging 2:33.3/500 meters.
In addition to the rowing 10K there were three other sessions. They were shorter, on both SkiErg and rowing machine, and they served as warmup before the 10K.

Today I tried to solve the problem of lack of good connection between dry Garmin heart strap and dry chest. Salty moisture like sweat is what the Garmin strap seems to need to get a good signal. Plain water doesn’t work well.
As a substitute for perspiration I added a few drops of water to a teaspoon of salt, mixed it together and applied it under the Garmin heart strap’s electrodes. It worked well and the signal from was good from start to finish.
Coincidentally, the heart worked well also in that it had none of that fluttery atrial fibrillation which tends to mess up the heart rate graph.

The sun was its normal color this afternoon but it felt so cold outside when I got a daily ration of a few minutes direct sunlight, that I wouldn’t have been surprised if it had been blue.
Today’s main workout was 10,000 meters indoor rowing at a steady pace whose average target was 2:33.4/500 meters. It was the seventh of seven sessions today.
In addition to the rowing 10K there were six other sessions. They were shorter ones, on both SkiErg and rowing machine, which served as warmup before the 10K. You can see the graphs and data for any of those by visiting this link to my online logbook, looking for log entries that were made on today’s date and clicking their corresponding “+” signs in the Action column.
But after all those warmups I was still cold with not an iota of perceived perspiration and that may be why it took quite a while for the Garmin heartstrap on the chest to start showing a signal. That particular heart strap seems to need to be very wet and perhaps a bit salty wet. Plain water doesn’t seem to do the trick. When it did start showing a heart rate signal, it was way too low. So the heart rate graph from the other heart strap, a Scoshe heart strap on the arm, will be shown also. It seemed to be realistically accurate.
I don’t know if I’ll be doing any rowing tomorrow… it depends on how I feel after having a root canal done by my favorite dentist.
Regarding the lately very popular topic of atrial fibrillation: It continued all last night and this morning but stopped in the afternoon, a little while after the 16 minutes of cold sunbathing.

Today’s main workout was 10,000 meters rowing at a steady pace averaging 2:33.5/500 meters. Heart rate was haywire during the session. The heart rate reading from the Garmin heart strap worn on the chest was erratic, not always displayed at all and was too low when it was being displayed. You can see its graph on the “RowPro Split and Stroke Charts,” below. The other heart strap gave a continuous reading which seemed to accurately display the much too high heart rate being experienced during today’s bout of atrial fibrillation. The other strap was a Scosche heart strap, worn on the arm. It’s graph is below also. It is the one that is red with a black background.
In addition to the rowing 10K there were six other sessions. They were shorter sessions on the SkiErg and rowing machine which served as warmup before the 10K.
