What Is The Best “Traffic Light” For Rowing?

Today’s rowing was a half marathon done at RPE Level 5, followed by an RPE Level 1 ten-minute warm down.

My “traffic lights” for whether its okay to do anything more than very easy rowing are three. Two of those are numbers: The EliteHRV Morning Readiness reading/analysis of heart rate variability and the total time of actual sleep. If EliteHRV says its okay to train harder today, then as far as that criteria is concerned I can row as hard as I want, for as long a distance or time as is possible. But my occasional irregular heart rate is casting a shadow of doubt on the EliteHRV Morning Readiness reading because according to the analysis so far of one who has expertise in the analysis of data – the reading may be skewed to result in being inaccurate, by the way EliteHRV deals with “artifacts” which in my case would be paroxysmal Afib.

So now I’m leaning more to another couple of “traffic lights” as “GO,” “CAUTION” or “STOP” signals for long and/or hard rowing: The amount of sleep I got the night before and, perhaps even more importantly, how I feel after waking in the morning.

This morning, all three of my “traffic lights” were “GO”. (1) EliteHRV, which is the one in doubt, said it would be okay to train hard. (2) I logged plenty of sleep and, even more importantly, (3) I felt good and slightly in the happy zone of emotions this morning. 🙂

EliteHRV Morning Readiness today
Last night’s sleep was 7 hours 25 minutes and I felt very good – happy- about waking and getting out of bed.

So today’s rowing was a half marathon scheduled online about 45 minutes in advance. At about 10 minutes before the appointed time, I checked in and was all alone. So I figured I would either row the HM solo online or cancel it and row it offline. While waiting for the scheduled time to arrive, I started typing text messages and sort of forgot about the online rowing session. When I next lifted my head to look at the computer monitor, there were two other guys who had joined and checked in and they were asking me if I was going to start the session or not because it was a few minutes past the starting time.

So I apologized for keeping them waiting and we started. One of them rowed for about 30 minutes and then disengaged from the online session. The other one rowed 10,000 meters in about 40 minutes and then he checked out also. So I rowed a bit more than the last half of the distance alone.

Today’s rowing was done first thing in the morning, before eating anything. I chose to do it that way, because from some of what I’ve read and heard in lectures on the topic of the body’s critically important mitochondria, there is some particularly important and even critical “repair and replacement” work that the mitochondria only does if a person has been fasting for at least 12 hours. Fasting at least 12 hours from evening meal to next day’s first meal seems, in my experience, to be very helpful for “repairing,” “resetting,” or some such thing with regard to my heart and its rhythm. That particular benefit of fasting is enhanced if a person is also active physically during the period of fasting.

By the time I started this morning’s rowing, I’d already been fasting almost 14 hours and by the time I finished rowing and ate something, more than 16 hours had passed. So – the heart’s mitochondria got the benefit of extra-special “attention and repair” during the last 4 of those 16 hours.

As you can see in this RowPro graph, heart rate sputtered a bit and had several brief periods of irregularity, before it smoothed out and behaved very well.

More Catching Up

Today’s EliteHRV Morning Readiness reading allowed for any distance or effort level.

Today’s rowing was mainly for the purpose of catching up on more of the “lost meters” this season. Last season my daily average meters was more than 10K. So far this season the daily average is a little over 5K, so I have a lot of catching up to do between now and the end of the season (April 30th).

More than enough sleep (8 hours 40 minutes) last night contributed to today’s favorable EliteHRV reading.

We got a late start this morning, so there wasn’t as much time for rowing as hoped. The two main indicators I use to tell me if its okay to row hard and/or long distance were both favorable. Those indicators are the EliteHRV Morning Readiness reading and whether I got sufficient sleep. The one that I currently give the most weight to is the EliteHRV Morning Readiness reading.

Since both indicators were “GO FOR IT!” I rowed 24,000 meters. None of it was hard rowing but the distance was sufficient that I feel relaxed for sleep this evening.

The four sessions rowed today were, in chronological order: (1st) 2K distance for warmup, (2nd) 10K online with two other guys, at an easy “overdistance” pace (which in this case meant a pace that would raise HR to no more than 55% to 70% of maximum). After the online 10K, there was a (3rd) 10 minute warm down which was 2,000 meters. Later in the afternoon, I decided to do (4th) another 10K and the plan was to do 2 or 3 intervals of 500 meters each and a final interval of 1,000 meters, with the pace of each interval at about 2:00/500m.

A view of the Concept2 online logbook showing the listing of today’s 4 rowing sessions.

But the heart acted up in its strange fashion and became too irregular to register a heart rate for a lot of the time. When it was registering a heart rate, HR was way too high and once got as high as 230 on the RowPro readout from the Polar heart strap. The Apple watch activity tracker, a separate heart rate logging device, showed high heart rate also. So, after a couple of 500 meter intervals at about the target pace of 2:00/500m, I slowed down for the remainder of the 10K. The main goal of completing the distance was achieved. Immediately below this paragraph is a screenshot of data for stroke number 888 through 918 of the strange-hearted 10K.

Strokes 903 through 913 are the highest heart rate I’ve ever seen displayed when my heart acts strangely.

Happy rowing to you.


26,954 Assorted Meters

The above photo shows a view of the back of my wind-swept head when I was standing on the bow of a whale watching catamaran recently. That photo is a screenshot taken from a video of the whale-watching. That video is on YouTube at this link: Gray Whales Rub Against Boat (Seen From UNDERWATER VIEWING PODS)

The whale watching was enjoyable, but it would have been a lot more fun if we had been rowing instead of just idly standing and sitting on the boat.

Today’s EliteHRV readiness score indicated that it was okay to row a lot of meters at virtually any pace.
Last night’s 7 hours 15 minutes of sleep contributed to this morning’s good HRV readiness reading.

Today’s rowing consisted of 8 sessions. If you count the warm ups and warm downs as sessions unto themselves, it consisted of a total of twelve pieces. Here is a listing of today’s rowing (see image below):

A screen recording was made of only one of the sessions, a 500 meter piece plus its warmup/down. That screen recording can be found on YouTube at this location: Indoor Rowing 500 meters with warmup/down 01022019

The various sessions were mostly easy, with an RPE rating of 2 or 3, with the exception of the above screen-recorded 500 meter piece, which was done at an RPE level of what felt like 9.

Happy rowing to you.


A Three Alarm HRV Reading

A picture of last night’s insomnia.  Heart rate is plotted with red dots which are heart rate samples once about every 10 minutes. Heart rate is not plotted for the period when I was awake with insomnia.  

Last night, I had a few hours of insomnia.  One result was that I didn’t get back to sleep until about 05:00 a.m. This morning was a day when it was necessary to rise early, to take care of a weekly, early morning chore. 

I always set at least 3 wake-up alarms, in case there is a malfunction with one or two of them.  The first one sounded and I reached up from deep under the surface of an ocean of sleep and shut it off.  Same with the second one and I was slightly more awake, but lay back down and closed my eyes to drift back to sleep.  It took the third alarm, to get me up out of bed, but I felt awful. 

So after completing the chore, I considered whether to go back to bed or stay up.  I went back to bed, but despite being very tired, could not go back to sleep.  So I got up, and took the daily EliteHRV Morning Readiness reading. It was the worst reading I’ve seen yet.  A fruit of a bad night’s sleep?   I rowed briskly yesterday, but neither terribly hard nor long..

Today’s EliteHRV Readiness reading after a three-alarm wake-up.

Whatever the reason, I limited myself to only easy, leisurely rowing today.  The main rowing session was 10,000 meters at a low heart rate pace.

The Fruits Of A Half Marathon

Two days after doing a half marathon, EliteHRV calculated that I had the best Morning Readiness score since starting to use the app!

One fruit of the Dec 15th half marathon is displayed in the screenshot above, which shows the best Morning Readiness reading I’ve had so far since using EliteHRV.  It came two days later and I think it is one result of the half marathon effort.

A second fruit was improved sleep. The above chart shows last night’s sleeping heart rate.  Though it seemed to me like it was good sleep, you can’t tell much of anything about the quality of sleep from that chart. But – this morning I received a notification and “inquiry” from my sleep logging app about my sleep the prior night, immediately following the half marathon. (see screenshot below)

Its analysis reports that sleep quality for the previous day’s sleep period (the night immediately following the half marathon) was “higher than is typical” and it presented  a couple dozen possible reasons, asking me to check off “all that apply” to that improved sleep quality, so as to contribute to its cause-and-effect analysis. The only one I checked was exercise, because the half marathon was the only thing out of the ordinary, since it’s 21,097 meters had been about 5 times my average daily volume so far this season and about double my recent several weeks’ daily volume.

The sleep of a labouring man is sweet, whether he eat little or much…” Ecclesiastes 5:12

Since today’s EliteHRV “Morning Readiness” reading said it was okay to train harder today, I decided to do another 10,000+ meters, arranged as a 10 minute warmup, a 6,000 meter piece at a target pace of 2:06/500 meters and a 10 minute warm down.

10K Recovery With An Easter Egg

Today’s heart rate variability reading was the surprise you see in the above screenshot.  Last night’s sleep was interrupted with insomnia but the total time sleeping was adequate.  (see screenshot below)

A bout of insomnia interrupted last night’s sleep between 2 and 4 a.m.

Assuming the analysis and advice of EliteHRV was correct, I chose to do a recovery 10K.  “Recovery” is relative and subjective, but a pace of 2:20 seemed like a good compromise, pending what the HRV result will be tomorrow.

So the 10K was done at a target average pace of 2:20 and an “Easter egg,” as a computer programmer might call it, was inserted when the distance counted down to 1,150 meters remaining.

Clearing Out The Cobwebs With A Half Marathon

Finish screen view of the half marathon portion of today’s rowing.

Sleep was good and more than adequate last night (see image below) almost 8 hours…

But the EliteHRV morning readiness score still refused to climb out of the “sympathetic” zone or higher than 7. (see image below)

So, I concluded that it may be as good as its going to get(?) and decided to be happy with 7.  Its a good number.

Today’s indoor rowing session was a half marathon with a simple plan.  The plan was to aim for and maintain an average pace of 2:14.4/500m until the distance counted down to 500 meters remaining. When there were 500 meters remaining, the hope was to row faster to the finish line, depending on how I felt by then. 

I felt okay, so somewhere during the final 500 meters, I decided to pick up the pace enough to aim for an overall average pace of 2:14.0.

There was a 750 meter warmup before the HM and a 1K warm down afterwards.

Happily, the heart behaved itself and wasn’t a spoilsport today.

For those of you who pay attention to the blog post categories:  I’m going to stop using the categories of Easy Workout, Medium Workout, Medium Hard Workout and Hard Workout.  Instead of those four categories, I’ll use one of 10 categories of RPE, which stands for Rate of Perceived Exertion. Today’s session is categorized as Rate of Perceived Exertion 3 (refer to chart below).  Because I was breathing easy (not “breathing heavily”) during 98.5% of today’s half marathon, it is categorized as RPE 3.

Previous 10K Redux But Better

Today’s score is the same as yesterday’s, though I got more sleep and HR is one BPM lower, so perhaps sleep and HR aren’t influencers of the score.

Because today’s EliteHRV reading is the same as yesterday’s, I won’t row a half marathon today and will choose a shorter distance than half marathon and an easy pace. The hope is, that I’ll eventually have an HRV morning readiness score that reads somewhere in the green, like it does this morning, but also in the “Parasympathetic” zone.  However… I don’t know yet if that is either desirable or necessary.

Last night’s sleep seemed slightly better quality and definitely was longer than the previous night’s.

So the decision is:  Today I will row 10,000 meters again at the same target of steady, average pace of 2 minutes 15 seconds per 500 meters.  But first I’d like some coffee…

The rowing is done and it went almost as hoped, with two exceptions:  (1) Heart rate was a little higher than expected for the amount of rest (no rowing yesterday) and sleep (7 1/2 hours last night).  Perhaps I need more than an average of 7 hours sleep per night?? (2) There were a few skipped heartbeats and two instances where Afib lasted a few seconds, during each of which the heart rate display went to zero on RowPro software display.

The coffee was very good.  Ground from fresh beans, full-strength caffeine level (instead of the “half-caff” variety I’d been having which had 50% of normal caffeine).

So anyway… those two un-hoped for things were the only less than desirable observations during the rowing session.  Other than that, everything was fine. Could it be that the higher caffeine level of today’s delicious coffee was what led to slightly higher heart rate than the same 10K rowed two days ago?

Sleep Issues Complicate Things

The HRV Morning Readiness score got a little worse today.

The influence of yesterday’s target heart rate choice of recovery session rowing is unknown, because sleep issues last night probably had a larger negative influence on HRV than anything else.

The big empty space in the graph of last night’s sleeping heart rate is the period during which there was no sleep.  Only about 3 hours 25 minutes of sleep logged.

After writing the above few words, I had to dash off to jury duty.

I assumed it would last all day and prevent any rowing.  But whoever was going to be put on a trial-by-jury decided to plead guilty. So the trial wasn’t necessary and my jury duty only amounted to answering roll call, filling out a form and listening to informational talks. It only lasted half a day, allowing rowing in the afternoon.

Today’s rowing was very similar to yesterday’s, except instead of using a target heart rate as the goal, I aimed for an average pace of steady-state effort at 2:16.0/500 meters.  That average pace was 7/10 of a second faster than yesterday’s average pace, but heart rate today was lower, at 128 BPM average, compared to yesterday’s higher heart rate of 131 at a slower average pace than today.

So today’s recovery 10K should have seemed slightly easier to the body than yesterday’s 10K.  If I can get a lot more than 3 1/2 hours sleep tonight, then perhaps tomorrow’s EliteHRV Morning Readiness Score will improve.

Once the EliteHRV Morning Readiness Score moves back up into the green zone that indicates I’ve recovered, then I will do harder rowing again to push it back to the yellow zone.

EliteHRV Says Its A Recovery Day

For 3 days, I’ve been taking daily HRV readings with the EliteHRV app. Today it is advising recovery.

Before today’s rowing: I was actually happy to see the YELLOW – CAUTION indication for today’s “Morning Readiness” because yesterday and the day before yesterday I deliberately did some harder rowing than has been typical for two days in a row, to see if the reading would react accordingly on the EliteHRV app.

Happily, it seems to be doing what I hoped it would do.  I feel fine this morning, but Heart Rate Variability shows that I’ve dipped into the “sympathetic” or “fight or flight” mode for the nervous system. 

So I have a choice to either take it easy and recover today, or do another harder rowing session and see if tomorrow’s reading dips further into the Sympathetic zone.  I’m tempted to row another session like yesterday’s and see if the reading will move further in the Sympathetic direction.  But then again… I’d also like to see if it responds to a recovery day by moving back into the Green of the Parasympathetic.

Decision is:  make this a recovery day with some Overdistance rowing.  Without a training partner to set the pace today, I’ll have to make the choice myself.  There are so many different ways to calculate what is the “ideal” effort level for recovery rowing.  But the rowing I’m doing is definitely not an exact science so I will just choose a target heart rate zone which seems moderate and maintain rowing effort to keep HR in that zone once it climbs high enough to reach that zone.

I will aim for a slow climb toward a target heart rate of 133 BPM, plus or minus 5 beats.  So that will be from 128 to 138.  If tomorrow’s Morning Readiness gets back into the green, I’ll know that the approach and that particular HR zone was good for recovery. 

After today’s rowing: So today’s rowing is done. It was 10K with a target heart rate of 133 BPM.  A screen recording was made and it is in the process of uploading to YouTube now.  In a few hours, it will be available for rowing-along-with, at this link: Indoor Rowing 10K Recovery 12102018

Happy rowing to you.
