Avoiding A Prime Number

AD-May-13th-2018-37min-52sec-finish
Finish screen for today’s 2,272 seconds of rowing.

Today’s indoor rowing session was a set time of 37 minutes and 52 seconds.  That’s because one of my “training partners” had rowed earlier, in the “just row” mode and because her session lasted 37:52.4 I thought I would use that as today’s goal, to match that time and do a fraction of a second more, making it 37:53 for my session.

Heart rate tried to be irregular during the first 1/3 of the time but then smoothed out for the remainder.

But when I calculated the number of seconds in 37 minutes 53 seconds, it came out to be 2,273 seconds.  That was a problem, because I wanted a total time, in seconds, which could be divided by some integer greater than 1 and less than or equal to 30, which is the possible range for the number of splits that RowPro can make for a rowing session.  I wanted to make each split the same as each of the other splits because otherwise RowPro 5 for the Mac always has some calculation errors with the last, unequal “remainder” split.

2,273 is a Prime Number,  so it is not divisible by any integer greater than 1.

So, instead of rounding the time up to 37:53, I rounded it down to 37:52, which amounted to 2,272 seconds, which is divisible by several integers in the range from 2 to 30.

Nonetheless, RowPro managed to activate a different glitch and do some miscalculating for one of the splits anyway, the sixth split. I thought that the 6th split was the most appropriate split in which RowPro would manifest a programming error…  Not that it matters in the grand scheme of things, but RowPro didn’t even record the correct amount of time for the 6th split.  The erroneous numbers in the record of the 6th split are in the columns for Time, Meters and Avg DPS.

The main “bottom line” numbers, the grand totals, are correct  and match what the PM-3 recorded on the rowing machine.

8591 Meters To Match A Training Partner

Finish screen for today’s 8591 meters.

Today’s indoor rowing was the first in several days.  I looked at my training partners and the most active training partner had rowed 8591 meters since the last day that I’d done any rowing.

So, I setup a RowPro session for that distance and that’s why the odd number was chosen.

Short Notice For Online 30 Minutes

ABb-May-6th-2018-30-mins-online-finish
Finish screen for today’s 30 minutes.

Today’s indoor rowing session was done online but it was scheduled only about 15 minutes in advance. Nobody who was interested saw it in time to join. There were other online sessions coming up that I could have joined, but I wanted to row immediately  and easy and if I’d chosen one of the other sessions, I would have been rowing later and under the influence of  faster people and therefore probably would have rowed harder than I really wanted to this morning.

So I set up a 30 minute session and rowed it easy, with only one non-easy bit that consisted of 10 strokes at a somewhat hard effort.

Twenty Minutes or One Minuet?

minuet-dance-couple
One minuet in dancing is more stately than one minute of rowing. But rowing is a better workout if you want to be able to get your heart rate elevated.

Today’s indoor rowing session could not be construed as a minuet because it was solo and lacking in stateliness.

Today’s session was almost nothing at all, because of other things happening in the morning and because after those things happened I decided to skip rowing today.

But then I logged into the Concept2 logbook and noticed that one of my three training partners had done some rowing today, in spite of the fact that she is going through chemotherapy and today was a “crash” day, she managed to get on the rowing machine and do 19 minutes 47 seconds of rowing.

That was inspiring.  So I decided to spend at least that much time rowing and did 20 minutes.

Today’s indoor rowing was a single 5K done at at target pace of 2:20/500 meters. That was half the distance rowed yesterday, but it was a little bit (7 calories, to be exact) more than half the calories burned yesterday.

Today’s indoor rowing session was 10K done with a pace target zone painted on the RowPro screen.  I aimed to maintain a pace that was just a little bit slower than maximum for that zone.

ROW FIRST, ANY DISTANCE!

Finish screen for today’s 10K.

The title of today’s post is the note that I wrote to myself on the notepad which is on a nightstand next to my side of the bed.  It was intended to remind me, first thing in the morning, to put off anything and everything else and just row, first thing early in the morning.

It worked.

Today’s “any distance” turned out to be 10K.  I set up RowPro so that it would display an easy pace zone with boundaries of 2:25 and 2:15 /500 meters and aimed for about 2:20. (All versions of RowPro allow you to designate and display optional target target zones for pace, heart rate and/or rating).

Heart rate was irregular for about the first 1,000 meters and then smoothed out.

The Session Got A Little Tacky

AMm-Apr-28th-2018-3K-finish
Finish screen for today’s 3K.

Today was a late morning start so the distance rowed was only 3K.  It was done at randomly varying paces.

I perhaps got a little carried away with some of the faster, sprinting bits… because I hadn’t warmed up and, perhaps due to that, the finicky heart rate started to climb near the end when it should have been slowing down if it was acting normally.  But it wasn’t being normal, it was being tachy , as in tachycardia.

During the last 1,000 meters I did a tiny little bit of sprinting and heart rate climbed up to 145 BPM when there was about 500 meters remaining.  At the 500 meters-to-go point, I slowed and rowed easy for a warm-down to the finish.  Heart rate went from 145 to 139, 138, 137, 135, 134… acting normal for a warm down after a little sprint and it slowed all the way to around 121 while I was rowing easy during the last 500 meters.

But then, even though I continued to row easily, heart rate climbed to 129, 131, 146, 147 … all the way up to 150 as I continued to row very easy near the end and when I reached the finish line it was beating at 148.

It remained high for a little while after rowing stopped, even though I hadn’t worked up a sweat and wasn’t breathing hard at all – totally normal breathing, as if I’d been being a couch potato instead of rowing, but heart rate was in the tachycardia zone for a bit.

After a few minutes it dropped below 100, which is the technical boundary for tachycardia.

The tacky heart behavior was rather annoying.  But perhaps I caused it? By annoying the heart?  By rowing later in the morning instead of first thing, before 7 a.m.?  It might be my imagination, but the heart and everything it’s connected to seems to prefer an earlier rowing session.

In addition to the tachycardia-ish behavior near the end, the heart rate went noticeably irregular a couple times during the session.  I felt it each time, and the heart rate display briefly went blank at those times.  You can see them on the graphs below, where the graph of heart rate spikes down to zero around the middle and near the end.

The session was uploaded to YouTube at Indoor Rowing 3K with a tacky finish 04282018.
