Erg Video

It’s been a while since I took side video, either on the erg or in a boat.  I had a little time yesterday, so I decided to do it.

To keep it reasonably short, I did 30 seconds each at 8 different rates from 18 to 32spm.

The first strokes are taken at about 30 seconds in.  So to specific stroke rates start at these times.

  • 18: 0:30
  • 20: 1:00
  • 22: 1:30
  • 24: 2:00
  • 26: 2:30
  • 28: 3:00
  • 30: 3:30
  • 32: 4:00

What do I see?

  • To my untrained eye, the drive looks OK.  The recovery less so.  I am breaking my knees too early on the recovery and my body is swinging way too late.  This is going to be a bitch to try to change.  It’s a pretty ingrained habit.
  • It looks like I am overcompressing at the catch.  My legs are not separating as much as they were, but they are not solidly together at the catch.  I think earlier body prep would help with this.

 

Lactate Step Test

Using the AIS Step Test Protocol

I estimated that my current 2k time would be around 7:00, or a 1:45 pace.  The protocol provides the following step powers

Screen Shot 2017-11-06 at 12.18.05 PM

Getting myself setup was a bit complicated.

  • HR sensor, connected to PM5
  • PM5 connected to painsled
  • headphones on, connected to iphone
  • Spotify set to my “8×500” playlist
  • Drag set to 130
  • Seat pad on erg
  • wet towel
  • dry towel
  • lancet tool
  • lactate meter battery OK
  • lay out 10 lactate test strips neatly
  • fan on
  • PM set to 4 minute intervals/1 minute rests, display to power

Then I did a baseline lactate test, just to make sure that I remembered the process.

  • wipe hands with dry towel
  • wipe sample finger with wet towel
  • dry sample finger
  • lance fingertip
  • pick up meter with non-sample hand
  • pick up strip with sample hand and insert strip
  • make sure meter has woken up
  • visually judge size of droplet
    • If it is too small, put hand down low for 5 seconds
  • dab droplet with strip, starts 13 sec count down on meter
  • wipe finger
  • get a drink
  • get feet set for next interval
  • write down reading

When executed well, this whole process takes about 45 seconds.  If there are any hiccups, it takes the whole 1 minute rest time.

The baseline was 1.4mmol/ml which is a perfectly reasonable reading.

Then I did the test.  The steps start ridiculously easy.  The key thing in my mind is to try to hit the power exactly on every stroke.  I ended up bouncing a few watts up and down, but staying focused on the target kept me occupied while it was easy.

The target for the last step is “max”.  I changed the display from watts to pace per 500.  I wasn’t quite sure how hard I could hold for 4 minutes.  I decided to try to make sure I did it faster than 1:45.  As it turned out, I was able to accelerate in the last minute, so I probably could have pushed it a bit harder, but my HR was above 180 at the end so I was working pretty hard.

11-7a

11-7b

OK, so I did the test.  What’s the point?

The main reason to do the test was to have a baseline to compare after training blocks are completed.

Beyond that, the curve can be used to estimate my current Lactate Threshold.  There are multiple ways to extract this from the curve.  The simplest is the power at which the lactate level exceeds 4.0mmol/ml.  This gives an estimate of 243W (1:52.9).  A more conservative method is to draw a best fit line for the sub-2.0mmol points and another for the steep part of the curve, and the point where they meet is the LT.

11-7c.png

This method yields about 238.  So, about 240 is a good guess.  How does this compare with the 20′ test?  The test measured 244W.  So there!

The other useful output is a first cut at appropriate steady state training power.  The goal here is to train at the highest power that results in a steady state lactate level at or below 2.0mmol/ml.  From this test, training power should be between 180 and 205W.

Other testing I have done in the past shows that lactate tends to drift up slowly over a long steady state session, so something towards the bottom of this probably more appropriate.

4 x 20′ / 1′

Same plan as the past couple of days.

  • 4 x 20′ / 1′ rest
  • rate: 19-21
  • power: 182W target
  • HR limit:
    • 0-20′: 145
    • 20′-40′: 150
    • 40′-80′: 155

Last two days were in the afternoon in a nice cool basement down on the cape.  Today was in the fitness center at work.  I was a bit concerned since Monday morning workouts tend to be a bit worse than others.

Started with my PT exercises (you can follow the link to the full list)

I started with the most important corrective exercise, Isometric correction for SIJ.  In this exercise you basically push you leg out while you hold it back with your arms.  It pushes the head of the femur back in it’s socket to get things aligned.  This addresses my big issue which is weak left glute.  Because of this weakness, other muscles are firing when I bend over for the catch and this is pulling the joint out of alignment.  After I do that, then I foam roller my quads and IT bands, do a diabolical thing called a hip flexor release which is bascially rolling around on a lacrosse ball looking for places that hurt.  Then I do a glute exercise which is like a bridge on a exercise ball, and then an exercise to strength my obliques.

It takes about 5 minutes and I think it is helping a lot.  I am noticing that it is way easier to keep my knees together at the catch, and my hips are rocking over in a much smoother way than before.  I suspect that it might have something to do with the increase in steady power that I am getting, but there isn’t a lot of evidence supporting that, other than the fact that I started doing PT and my steady state power got better.

At any rate, it isn’t hurting anything, so I’m all for it.

The session went better than I hoped.  I aimed at 182W, but 185W felt fine and my HR stayed nice and low, so I went with it.  I kept going at that through 3 20′ pieces and then pushed a bit more in the fourth.  holding 190 was a bit too much and I needed to back off to 185W to stay under the 155bpm cap.  It was great that my HR came down nicely when I reduced the power from 190 to 185.

I thought it would interesting to look back over the summer to see if this feeling of getting better was actually accurate.  It is.  You can see power going up and down, and then recently getting much better and more consistent (narrower range).  On the right, you can see avgHR around the same and the upper HR a bit lower, but a nice downward trend over the past few days.

Tomorrow:  I it is time for a bit more intensity and a bit more testing.  I think I will do a lactate step test using the AIS protocol.

The power levels for this test are supposed to be based on the prior years best 2k test.  I will estimate 2k power based on the 1K and 20 minute tests from last week.  Using the Free Spirits Pace Predictor, I get an estimated 2K time of 6:59.0.  Using the CP Curve from Rowsandall, I get a range of 280W to 326W (1:47.7 to 1:42.4), right in the middle of that would be 1:45.

So, here are my targets…

Screen Shot 2017-11-06 at 12.18.05 PM

The protocol is row for 4 minutes, take a minute to do a lactate, then do it a 6 more times.

4 x 20′ / 1′ + 2 x 1’/1′

Same session as yesterday.  Same rules.

  • 4 x 20′ / 1′ rests
  • rate: 19-20
  • power target: 180W
  • HR limit: 145 after 20′, 150 after 40′, 155 after 60′

I felt great in this session.  My stroke felt stronger everything just felt easier.  Not sure why, but I sure liked it.

I was under my HR limit after 40′, so I nudged the power up just a couple of watts.  My HR stayed nice and low through the third piece.  So, in the last piece, nudged it up more for the first 10 minutes of so, and my HR was still ice and low, so I decided to push even harder to see what it would take to get up to the 155 HR limit.  I needed to hold about 195 watts to slowly get up to the limit by the end.

I am more than ever convinced that I need to start low and push up over a session.  Some people are able to start hard, and then ease off.  That never seems to work for me.  I will stick with 182W as a starting power, and stick with that through the first 40 minutes.  If I am well under the cap, I will push harder in the second half.

After I finished the main course, I had some dessert.

2017-11-05 13.44.59

I went all out in the first one, but with low drag and tired legs.  I expect that I could squeeze out a bit more distance if I did it fresh and set myself up for a proper sprint.  Considering my best 500m was 1:28.4, I hope I can improve this as I go along.

Tomorrow:  Another base builder session.

4×20’/1′

Base building now.  Waiting until I get a plan from Marlene.

That went very well. Initial power target was 175W, but 177 felt good.  I was under the HR limits at the end of 40 minutes so I decided to inch up the power a little.  Then a bit more in the last 20 minutes.  I felt relaxed and good through the session.

Fall 2017 Fitness Tests

Screen Shot 2017-11-03 at 12.40.07 PM

This is in a google sheet: here

A little explanation:

  • Power:  Is the average power for the test (or the peak power in the case of the peak power.
  • PR Power:  Is the best performance over the past 4 years for the closest thing to these tests
    • Peak Power:  Low Pull Test in 2014
    • 75 Minute Test: Half marathon in December, 2015 (79:55 minutes vs 75:00)
    • 1K test: 1K test in March of 2014
    • 20′ Test: 6K test in December of 2013 (21:32 vs 20:00)
  • % PR Std:  This is how far I am from my best ever performance for this set of tests
  • 500m: Avg or peak split
  • Meters: Distance rowed, significant for 20′ and 75′ rows
  • SPM:  Avg stroke rate for the piece
  • Ratios:
    • 75′ test: % of 1K test power
    • 1K test: % of peak power
    • 20′ test: % of 1K test power
  • Ideal:  This is the range define my RoyleRow as idealized target ranges to help focus training planning
  • PR Ratios:  This is the same ratios calculated from PR powers instead of current test results.

The purpose of this exercise is to provide insight about training.  So, what insights are there.

  1. It is cool to see how consistent the ratios are from my best performance to my current performance.  I think that a big part of this is physiology.  My VO2Max to peak power is higher than target range, and my anaerobic and aerobic thresholds are below the ideal ranges by similar amounts.  It will be interesting if Marlene will want to focus on trying to raise my threshold results relative to my VO2Max, or if she will want to just push the whole profile to the right
  2. My peak power is closer to my PR levels than my distance stuff.  I think that this makes a ton of sense.  My total training load, and especially my load of aerobic training was much lower over this past summer than in past seasons due to travel, boat problems and injury.
  3. I was disappointed with the anaerobic threshold results, but it sure explains why I didn’t do as well as I hoped in the HOCR.  It appears that this furthers from my best performance and furthest from the ideal ranges.  This is also related to problems with training this summer and fall.  I essentially had 21 total days from when I restarted “real” training after my back injury before until the HOCR.  That was not enough time to move my anaerobic threshold much.

I will find out soon what Marlene wants to do, but my thought is to work on aerobic fitness using lactate guided training power, and complement that with a few short sessions a week at higher intensity.  I would also like to devote more training time to fixing some core strength and imbalance issues.

If at first you don’t succeed…

After yesterday, I was nervous and frankly full of dread about doing the 20′ time trial today.

I saw yesterday that 1:50 was too aggressive as a target, so today, I backed off to 1:53.

I started with a very short 1k warmup.

Then onto the main event.

  • Pace target: 1:53
  • Rate target: 25

I promised myself to not quit on this test.  If I needed to, I would slow down by a split or two, but I would keep going and just get it done.  After all the point was to establish a baseline for the purpose of planning my training.  If the test shows that I am weak here, then that is useful data.  Useful data that really hurts to collect.

This was pretty hard from beginning to end.  I was very worried about halfway through and I started playing around a little bit with rate and pressure to try to find a comfortable groove.  I was counting blocks of 125 strokes for each 5 minute section.  My HR was above 95% of HRR with 6 minutes to go and I was pretty miserable in the last 5 minutes.  I eased off a bit until I saw that I had 2 minutes to go, actually when I had counted to 75 strokes in the last section.  Then I pushed again to try to finish strong while counting down the last 50 strokes.

So, I ended up a bit below target, but this was a good solid test.  I think it reflects where I am right now.

After I caught my breath, I did a 3K cool down

Tomorrow:  Recovery session.  If the weather is nice, I’m hoping for a open water row.

I’m compiling the results and I I’ll post the analysis in a little while

 

Well that didn’t go well

Yesterday, was a rest day.  I spent the day on appointments and errands

  • Dentist appointment:  Which made me unhappy because I apparently have a cracked tooth and need a crown.
  • PT appointment:  Which hurt like hell.  I have two issues.
    • My left glute is weak and this is causing a misalignment in my hips.  This has caused a chain reaction of sorts resulting in my left quad being all tight and my legs presenting as different lengths.
    • The very bottom part of my spine above and below my L5 is a bit out of alignment and the PT believes that I have impingement between vertebrae when I lean back at the finish.  I need to work on rocking my pelvis forward in rowing and in real life.
    • First he did some deep tissue massage to try to get my lower spine unkotted.  That wasn’t so bad.  Then he moved onto the left quadricep and tried to work out some adhesions that had formed between the different elements of the quad.  He used a combination of deep tissue massage and active release in two different poistions.  This hurt so much that I wept.  After that, he showed me a couple more exercises to work on strengthing my glutes and obliques to try to support better pelvic posture.  I limped out of the appointment.
  • From there, I headed off to the Apple store.  I dropped my phone on a concrete floor on Sunday and cracked the screen.  I discovered that the screen can be replaced reasonably easily.  They said it would be done in about 90 minutes.
  • Next stop was a radiology center.  In my hip X-Rays, the radiologist saw a “deformity” on one of my ribs on the right side and recommended a follow up x-ray of the area.  So, I did that.  I wonder what will come of it?
  • Then back to the Apple store to pick up my repaired phone.

Whew!

Thursday

The plan for today was a 20 minute test.  I got a good night’s sleep and I headed into work.  I was in the gym by about 6:45.  I started with a 2k warmup.

Then, I gathered my courage for a 20 minute time trial.  Based on the rowsandall OTE CP Analysis, my projected power for a piece this length was between 245W and 285W (1:52.6 to 1:47.1).  The wide band is the result of pretty funny looking CP curve.

Why does it look like this?  Well, that’s because the data extracted from erg pieces (red dots) is based on 3 strong results (75′, 1km, LP).  The plateau from 50 seconds to 200 seconds is the data from the 1K test.  The low end was set by the peak power test.  The upper end was set by the 75′ test.

Just from recent experience, it seemed that 1:47 was way to big of an ask.  I thought that 1:50 might work, but was risky.  I decided to start there and slow down if needed.

I got myself setup and got going.  I held 1:50 through the first 1250m, but I was in a lot of respiratory distress, and my HR was a bit higher than I was hoping to see.  I basically lost hope and stopped.

Humph.  That was disappointing.  I sat around for a little while trying to figure out what happened.  I had a bit of DOMS in my quads from the PT appointment, but that didn’t bother me much.  My HR was definitely a bit high and I was struggling, but slowing down didn’t seem to work.  I think part of my problem was just an unwillingness to endure the discomfort today.

After mulling it over for a few minutes, I decided to give it another try, but this time at 1:52.  This didn’t go any better.  I lasted about the same amount of time, and gave up when it started to hurt.

After that, I gave up and just did a cool down.

I wanted to compare these failures to the reasonably successful 6K session that I did on October 9th.  The orange trace was the first attempt.  You can see I started at about 265W and faded a bit toward 250W through the first 5 minutes.   The HR response was much higher today than in the 6K test.  It seems pretty clear that that the fatigue from the first attempt was effecting the HR for the second attempt.

So, now I try again tomorrow.  target is 250W.
