Chasing The Elusive Narrow Zone

Waiting for a good day to do a hard 30 minute session and in the meantime conserving energy by rowing in the elusive heart zone one. Today was 10K with that zone (heart rate zone 1) as the target. If you glance closely at the graph and painted target for heart rate zone one on the finish screen, you can see that I chased a wee bit too hard, causing heart rate to frequently jump up out of the zone. The chart in the session report doesn't show that degree of detail for HR variations. Skittery jittery heart.

Sufficient Sleep Promotes Enthusiasm

Last night I went off to bed at about 8 pm.  That's much earlier than "usual".   It worked out very well because for the first time since about March 18th I managed to get a full 7 hours sleep.  And then some.  Of the 8 hours and 50 minutes in bed, 8 hrs 20 mins was actual sleep.

That might be part of the reason why today felt like leaping for joy, relatively speaking, compared to yesterday and much more ready to do some rowing today.
I feel more leapy when not so sleepy.  Thanks for all the fish.
 Today's session was 10K with the only goals being to do the entire 10K (instead of quitting the  prematurely like yesterday) and  to continuously adjust effort to keep heart rate in zone 1 for the sake of conserving energy for a hopefully soon 30 minute online race or solo attempt at a new season best.

Unfinished

Today's session was supposed to be 8450 meters in zone 1 but due to a lack of enthusiasm it was cut short.
 Though the entire session wasn't finished, here are the results...

An Exercise In Restraint

Today's piece was 12,000 meters all done in the lowest aerobic workout heart zone, which is zone 1 of 5.

Heart zone 1 was chosen because there's the possibility of a 30 minute race or season-best record attempt in the near future.

From Easy to Slacker

Today's rowing was done before breakfast or coffee with a target of heart zone 2.  The effort was constant for the first 5K but then I had to slack off a bit on effort, to pull heart rate back down into zone 2. So as a result the first 10 splits were done at something over 150 watts and the last 10 were each done at less than 150 watts.

Easier But Faster and Wilder

Today's 10K was supposed to be the same as yesterday's:  keep the heart rate in zones 1 and/or zone 2.  But the pace turned out to be quite a bit faster, 2:12.4 vs 2:14.2 yesterday.  Average watts today was 149.1 vs 145.0 yesterday.  Calories today was 600 vs 595 yesterday.

It felt easier as far as effort was concerned, but heart rate was noticeably wilder, with a lot more variations for the same effort, especially in the first half of the 10K, than yesterday. During the first few thousand meters, the heart rate display went blank several times also, but it doesn't show as having done so on the session report.

The only thing that comes to mind which might have made a difference is that I had breakfast and  two cups of strong coffee before rowing.  Usually, I do the rowing first and then have coffee and breakfast as a reward afterward.  If caffeine made that much of a difference then perhaps caffeine should be considered a "drug" and not allowed during Olympics and other races.

Just joking, of course, about coffee as a drug that should be disallowed.  The results of today vs yesterday aren't radically different, but mentally/subjectively speaking.... it felt a lot easier.

Spaced Out Swallows

The plan for today's rowing was to do 10K while staying in heart rate zones one or two and pausing momentarily every 1000 meters to take a sip and swallow of the first cup of morning coffee. The mission was accomplished.

She Laughed At The Evidence

Yesterday I looked at what data could be found on Diane's previous no-sweat rowing sessions, going a few months back and printed up a 3-page report, showing her the evidence that she had rowed too slowly during the 20 minute heart calibration.  The report was actually 4 pages, because it included the following cover page:
But after Diane realized what she was looking at and examined the documentation which proved she had done the 20 minute calibration at too slow a pace, all she did was laugh.  It's almost like she and I are from different planets.  Which of course we are.

Today's session was 10K with the only target to be anywhere within the boundaries of heart zones 1 and 2.

Brain Shrinkage Narrowly Avoided


Color me happy!
This afternoon I napped for one hour and forty seven minutes, which raised today's total sleep to 6 hours 5 minutes.

According to some sources which shall remain unnamed because I don't remember, six hours is the minimum daily sleep a man needs, in order to avoid brain shrinkage.

Enjoying the New Quantum Level of Leisure Rowing

Today's session was done at an easy rating compared to yesterday's more demanding rating target of 18.  But the best thing about today's session was that because of the recently updated and increased lactate threshold heart rate, I could let heart rate go quite a bit higher and still be in HR zone 2 without worries about working too hard.

The only glitch today was that the heartstrap battery got too low, at 10% charge remaining, for it to function during the entire session.  So that is why heart rate shows as zero during the last few splits.

Regarding Diane's heart rate calibration which I wrote about yesterday, I think her results were so surprisingly low because she was being extra careful to start out extra slow, so that when she was called upon to do perceived exertion level 6 for three minutes, she wouldn't be in danger of straining herself.  Caution is good and I'm glad she was too cautious rather than injure herself.  But I looked at the average pace she rowed for all sessions from the October 30, 2015 session until the most recent one before the heart rate calibration and her average pace for all of those was 4:36/500 meters.  During none of those sessions did she sweat or even perspire and most of those sessions were around 40 minutes in duration.  So she rowed all of those sessions at an average pace which was a bit slower than a normal warm-up pace, because though 30 or 40 minutes at a warm-up pace will not cause a person to sweat, it will induce a very slight amount of perspiration which will give the person a sensation of cooling when air moves over their skin. My dear, sweet and enchanting Princess Diane has told me many times, in no uncertain terms, that she doesn't like to sweat or perspire. Therefore I conclude that she was rowing all of those 30 or 40 minute sessions at what would be a slower-than-warmup pace.

Her average pace for yesterday's heart rate calibration session therefore should have been a faster pace than any of those previous sessions, because the first 5 minutes and the last few minutes were done at what should have been a warm-up pace equal to or slightly faster than what she normally rowed in those 30 to 40 minute sessions and the rest of the calibration session was done in 5 increments, each of which was a slightly higher pace than the one before, with the fastest pace during the calibration sustained for 3 minutes. So each of those increments during the calibration should have raised the average pace for the session a bit more.

But... her average pace for the entire heart rate calibration session was 6:04.2/500 meters, which was much, much slower than her normal, easy, no-perspiration 40 minute sessions which were all done at about 4:36/500 meters with the exception of one of them which was done at an average pace of 5:11.7/500 m.  The latter was probably slower because it was probably either a fixed distance or time and she probably paused to operate the remote control, drink cocoa, etc during that particular session.

As for today: here's the finish screen and session report for my rowing today:
The heart strap signal dropped out before session ended and that is why it appears heart rate dropped.  I was wearing a device on my wrist which also displayed heart rate and it was 136 to 144 whenever I checked it during the last few splits after the heart strap quit.

Heart Rate Calibration for the Deaf

To calculate lactate threshold heart rate and the corresponding HR zones for use with aerobic workouts, the easy way is to use the Pear Sports smartphone app.  You can read about it on Pear Sports website or in Matt Fitzgerald's book, "80/20 Running: Run Stronger and Race Faster By Training Slower".

The hard way is to locate an exercise laboratory, make an appointment and pay to be scientifically measured with analysis of periodic samples of your blood while you are put through a series of specific paces.

The easy way is, for all practical purposes, just as accurate and far less expensive than the hard way.

An article on the subject, by Matt Fitzgerald, provides more information and takes a good look at the topic.  You can view that article by clicking on THIS LINK to the article, which is titled "Go By Feel, Skip The Lactate Threshold Test."

There is a special obstacle for a deaf person to utilize the heart calibration workout in the Pear app.  All the prompts and other information is 100% audio with no visible aid such as subtitles or captions. A deaf person would have the same problem, doing the test in a laboratory, since the laboratory technicians would not have subtitles or captions whenever they would speak instructions.

Diane  and I discussed the dilemma for her of how to determine the "just right" effort level without either rowing too easy or too hard.  After I once again attempted to explain to her how the lactate threshold test and calculated heart rate zones are used, she had a minor epiphany and decided to take the Pear heart calibration.

It was the first time for her, so she will probably need to take it a few more times in order to zero in on the most accurate results.  Diane is more deaf than most people who are born deaf.  Without hearing aids, a blaring trumpet is a whisper ... or less than a whisper.

Her deafness happened gradually over many decades of relative normalcy with regard to speaking and hearing.  But now she is "stone deaf" and because of her hearing problem, I volunteered to help her by printing out all of the prompts and other spoken words and holding them up for her to read at the appropriate times during the 20 minute workout.

I emailed both Pear Sports and Matt Fitzgerald about the possibility of getting a copy of the transcript, so as to save some time transcribing it myself.  While waiting for a response, I did the 20 minute calibration workout and recorded it.  Then I went to work transcribing all the recorded words.  But before I finished that transcription job, Matt Fitzgerald graciously responded by email and attached a copy of the transcript.

Matt's transcript was better than what I was typing up, because his included helpful time stamps corresponding to where each paragraph was spoken during the 20 minutes.

So I showed the transcript to Diane. She read it through once, to get an idea of what would be asked of her during the 20 minutes.  Then I told her I was going to print out each paragraph on a separate page, in an extra-large font and hold up each page when those words were spoken.

But Diane said she would rather I sit in front of her, so she could see my lips as I would read each paragraph out loud.  I am very self-conscious as a public speaker but quite the opposite with Diane.  So I happily agreed and that's what we did.

It was actually quite a thrill for me to be close to her while she did the 20 minute session.  We only have one rowing machine and I'd never spent any time in the room with her before, when she was rowing.

Diane is an excellent lip reader and so with the combination of her super high-decibel hearing aids plus her lip-reading skills she was able to understand everything perfectly.

The results were quite surprising though.  Diane's lactate threshold heart rate was much lower than my lowest guess had anticipated.  Based on my own early experience taking the heart calibration test the first few times, I suspect that she did the same thing I did at first, which was to row at an effort level that was much easier than called for and described.  So, hopefully, we can zero in on more accurate results for her with a few more tests.

As for my rowing today, it was 10K done with a RowPro painted target zone centered between the new boundaries of recently calculated HR zones 1 and 2.  There was an additional targeted zone for the session, which was a rating of about 18 strokes per minute.
The old heart rate zones are on top and the newest calculated zones are on the bottom.
Screen shot of my HR calibration yesterday.
If you compare the screen shot of the Pear app calculated results for the HR calibration I did yesterday to the spreadsheet printout of them in the lower area of the photo above, you will notice they are not exactly the same.  That's because the spreadsheet takes into account what amounts to a "buffer zone" between zone 2 and zone 3, as explained in Matt Fitzgerald's 80/20 book.
Finish screen of today's 10K session.
You might notice in the HR graph on the view of today's finish screen, above, that toward the end of the session my HR was slightly above the top of the painted area which represented the upper boundary of Zone 2.  I didn't fuss about that, because it was in the "buffer zone" between Zone 2 and Zone 3 and that's what a buffer zone is for... its an area to minimize or mitigate conflict between actually working too hard and almost working too hard.

Heart Rate Calibration

There's a cool smartphone app by Pear Sports which is called PEAR Personal Coach.  You can read about it either on their website at pearsports.com or wherever you get the apps for whatever brand of smartphone you use.  It's an interactive app which emulates a personal trainer to some degree by incorporating a little bit of artificial intelligence.

Some of the workouts they have are free and the others are by subscription.  One of the free apps is called Heart Rate Calibration and it is something that you must do before you use any of the other workouts because the other workouts refer to your personal calculated heart rate zones in order to determine if you are working too hard,  not hard enough or if you are in the Goldilocks zone of "just right" level of effort at any moment of time during the workouts.

Because a person's fitness level changes according to what they have been doing and how active or inactive they have been during the previous few weeks, Pear Sports recommends that you do the heart rate calibration every 4 to 8 weeks, to keep it fresh and up to date.

It had been a lot more than 4 weeks since I'd done my most recent HR cal, so today I did an update.
The heart rate zones I will be using for reference in the immediate future.
Today's rowing was two sessions:  a 21 minute timed piece to accommodate the HR calibration and a 5500 meter piece to bring the total distance rowed today to a little more than 10K.
finish screen for heart rate calibration
The heart rate calibration was done with a special bluetooth heart strap which is necessary for use with the Pear app.  But it doesn't work with the Concept 2 heart rate receiver, so there is no HR graph on the above RowPro finish screen. Or on the session report for that piece.
Heart rate irrelevant but you can see how the pace/effort level was stepped up in response to the prompts by Matt Fitzgerald on the heart rate calibration workout. 
If you want to read more about the science and research behind the heart rate zones and the training approach, a good book is the one by author Matt Fitzgerald.  It's title is "80/20 Running: Run Stronger and Race Faster by Training Slower".  Though it refers to running throughout the book, it is easy to translate it to rowing since they are both aerobic activities.

Just Dive In!

Do you wonder how to go about beginning with indoor rowing?  Its like your first experience swimming in the ocean -just dive in and start swimming and playing in the waves.

Of course, you want to be sure its a safe beach first, with no sharks, riptides or poisonous jellyfish waiting to ambush you. The locals can give you all that information.

With indoor rowing, the main thing is to look at the diagrams on the Concept 2 rower and imitate the posture and positioning for the 4 positions shown.  After that, limit your very first session to no more than 20 or 30 minutes at an effort level that seems effortless... and before you are finished with your first, effortless 20 or 30 minute session it will dawn on you that there are definite signs that you have been working.  Even though it doesn't feel like work at all, when you row at an "effortless" pace.

If you feel okay the next day, you did it correctly and you can be happy about that.  Very happy.

And if you really, really want more advice from me:  always wear a heartstrap and observe what your heart rate is doing.  To wear a heartstrap or not is like the difference between walking in the daytime compared to groping your way while walking on a totally dark night.

Just dive in!
Today's session was another 10K:

There was no warmdown, not so much as even one minute of warmdown at the end of today's session because my thoughts at that point were, "I didn't get "hot," so why bother warming down?"

A Focus Factor Finding

Yesterday there was a problem with getting started.  After getting started yesterday, there was a severe lack of focus.

This morning the problem of getting started was addressed by "just doing it" - sitting down and starting rowing- before even making coffee.

The problem of focus was addressed by once again resorting to music.  I had read recently that familiar music from times of childhood and youth can activate parts of the brain that are most closely connected with mental ..... sharpness ... acuity (to abbreviate the longer explanation).  So I looked for and found a playlist in Spotify which consisted entirely of music from the 60's, when I was in my late teens.

It may have been the "focus factor" in today's rowing session because maintaining a constant effort level to keep heart rate within the painted target zone on the RowPro heart rate display was almost effortless.

For the session, a distance of 10K was chosen partly for the sake of the two Concept 2 challenges in which I'm currently involved as a member of the RowPro Rowers team: Mud Season Madness and World Erg Challenge.
Constant effort level was maintained until the last minute when reduced for purpose of warming down. The downward spikes in effort level were to mute and un-mute sound when advertisements came on and ended.

In a Holding Pattern

When an airliner has to wait its  turn before being allowed to land, it will fly in a holding pattern.  The holding pattern will be just enough effort to keep it airborne and in the altitude and route it needs to fly, while it waits.

Today I didn't feel like rowing but managed to talk myself into rowing in a holding pattern of sorts.  The chosen session length was a distance equal to my daily average so far this season: 8,398 meters.  The chosen effort level was anything that kept the flywheel rotating.

About half the session was done while rowing one-handed and operating a remote control with the other hand.

A 12,000 Meter Oxymoron

Today's daily distance dose was done online.  And it was done solo which is contrary to the main purpose of rowing online and therefore somewhat of an oxymoron:  rowing online alone.

But I only scheduled it 24 minutes in advance and so it was really no surprise that nobody else showed up for it.
If you surmise that I was rowing sedately and there were periods of distraction, you are correct.

Happy π Day to Everyone!

To celebrate π day today, I watched a 2 minute 31 second video about making a Raspberry Pi Stroke Coach and decided that is an advantage to using an indoor rower instead of rowing on-the-water: The Concept 2 rower constantly displays instantaneous stroke rate with each stroke.

Today's rowing was a little over 12,000 meters but it was done in 8 individual pieces: two short warm ups, five x five minute sessions, online with three other people and lastly a 4,200 meter warmdown.
