Wednesday: 1 Minute Power Test

So, I know that I was supposed to do a light day today, but looking at my work schedule, it didn’t look so good for a power test tomorrow.  I also felt pretty fresh.  I didn’t need to dig all that terribly deep for the 2 speed test.  Finally, thinking about the 2K test, the idea of keeping up the intensity seemed to more closely mimic the kind of taper I like to do.

The challenge was the PM on the erg.  I was doing this at work and it is a older model C with an old style PM.  The kind that you can’t hook up to rowpro.  So, I pulled my PM3 off of my erg at home with the idea of swapping it onto the erg at work for the day.  I was stymied by the fact that the mounting bracket has been changed between PM models and the new one would not fit on the old bracket.  Bummer.

So, I ended up setting my iphone on a upturned trashcan, leaning against a small dumbell and aiming at the PM.  Then I laboriously transcribed the power reading from each stroke into excel.  If you want to watch some really boring videos, I posted them to youtube.

Why are there two, you ask?  Well, there’s a story behind that.  Not much of a story, but a story nonetheless.

I did a nice gentle 20 minute warmup, and then got myself psyched up for the test.  Apparently I did not get myself psyched up nearly enough, because I blew up big time 32 seconds into the test.  I took the go all out advice to heart and I just totally lost it round the 30 second mark.  I was on slides, so I was cranking at close to 50 SPM.  I was rowing mostly with my eyes closed, and then opened them after about 25 strokes.  When I saw I had only made it halfway, I suffered a bout of acute despondency and dropped the handle.  Pity, it would have been a good test if I had the guts to keep going.  As it was, I set a new PR for peak power.  770W vs my old mark of 701W.  I also maintained with 10% of that value for 25 seconds, which shows that my “Anaerobic alactic critical duration” is reasonable.  “Rowing Faster” says you want to be able to hold that for longer than 20 seconds.  Of course for the other measures, average power and “Anaerobic lactic critical duration” were not measurable from this failed test.

I took a few minutes to get my head together and tried again.  This time, I made it less than 20 seconds into the test and I didn’t bother to transcribe the results.

I had a chat with myself, and decided to make yet another attempt, even though I knew that the test results would not be fully valid.  At least I would be able to get a completed test to score.  Maybe I’ll loop back to this in a week or so.

The last attempt was fine.  I definitely paced myself too much.  I certainly had a lot less power in the initial burst.  This one peaked at 726W.  AACD was 18 seconds.  ALCD was 60 seconds.  Average Power for the minute was 606W.  Maybe I was dogging it, but I was fairly shattered after I finished and the long 20 minute cool down was a struggle even at a 2:10 pace.

To summarize:

  • Peak Power: Target – 837W to 1023W, Actual: 770W
  • Average Power: Target – 674W to 814W, Actual: 606W

So, basically horrible compared to the benchmarks.  By the way, I don’t know too many guys my age with a low pull of 1:12.  Frankly, I don’t that many guys with a low pull of 1:12, so I am not sure how realistic these targets are.

The important thing is that it gives me something to compare against in future tests.  I will feel better if I redo the test in a week and get a complete first shot test done.

Here are my curves

power test

Here’s the HR plot for the whole disaster.

Tomorrow:  40 minute steady state sometime during the day.  Then 2K trial on Friday.

Tuesday: 2-speed test

Test Protocol documented in yesterday’s post here

Done on my erg at home (static) with RowPro.

The 2-speed test is a 2 x 1000m with 15 minutes of rest between intervals.  The first interval is to be done roughly at LT pace, basically a 6K kind of pace.  For me right now, around 1:50 or so.  The second at V02Max pacing, basically 2K pace.  That would be around 1:42, but faster is better.  It’s supposed to be close to all out over the 1K distance.

I started with a 20 minute warmup.  I’ve been starting off more slowly lately and I like the change.  I used to do a Fletcher warmup, at the prescribed paces, but that starts at something like a 2:05 for me and then gets quite fast and frankly takes a lot of effort.  Now I start at 2:15, and then gradually pick up the pace and then do a few bursts at target pace or faster.  Then finish slowly.

Then into the main event.  I set up Rowpro for variable intervals so that I wouldn’t have an extra 15 minute rest after my last interval.  I it up as follows

  • Variable Intervals (Distance, no rest)
  • 1000m Hard
  • 900s stop (you put the time in the distance box, don’t ask me why, but it works)
  • 1000m V. Hard

Lactate readings were taken at 1′ and 3′ after each interval.  The readings were:

  • Post LT Interval: 1′ – 5.6mmol/l, 3′ – 4.5mmol/l
  • Post VO2Max Interval: 1′ – 10.7mmol/l, 3′ – 10.7mmol/l

This results in the following chart:

11-10 2-speed

Future tests will show changes in aerobic fitness through displacement in the x-axis.  Changes in anaerobic fitness will show in changes in the slope of the line.

After that, I did a 2K happy ending, starting at 1:50 and slowing down by 5 seconds each 250m.

Screen Shot 2015-11-10 at 12.04.15 PM

So, that’s that.  I was happy that I could hold sub-1:40 for the second 1K.  I think that bodes well for being able to do something around 1:43 or better for the 2K test.

The rest of the test week is as follows

  • Wednesday: easy day: 40′ steady state
  • Thursday: 1 minute power test, then probably the November CTC
  • Friday: easy day: 40′ steady state
  • Saturday: 2K Test
  • Sunday: Easy day: 40′ steady state
  • Monday: 6K Test

End of Season Fitness Testing

The purpose of this testing period is to determine current fitness, balance of aerobic versus anaerobic capability.  The findings will be used to set priorities for my winter training plan.

My intention is to repeat this same set of tests at the beginning of each major training period to allow me to track long term trends in fitness and witness the ravages of aging quantitatively.

There are 4 specific tests.  These tests are to be done in this specific order.  Only one test will be done in a training session.  A light day of 40 minutes of steady state rowing (<2.0mmol/l lactate power) between each test day.

  1. 2- speed lactate test
  2. Anaerobic Fitness Test
  3. 2K Test
  4. 6K Test

Detailed Descriptions

  1.  2 Speed Lactate Test.

(source:  The Science of Winning, Jan Olbrecht.  Original Source:  Mader A. and H. Heck: A theory of the metabolic origin of “anaerobic threshold”. Int. J. Sports Med. 7, 45-65, 1986)

The Science of Winning is a book about training for competitive swimming.  Since spint rowing events are similar duration to longer swimming events, a lot of the training principles are almost directly applicable.  The 2 speed test is presented as a way to assess the balance of aerobic and anaerobic capability in a swimmer by completing the same test distance twice.  After a thorough warm up, the first trial is done at a submaximal pace, and then after a long rest (15 minutes, active rest) a second time as fast as the distance can be completed.  The test can be done on different distances.  In the book, it was presented with 100m, 200m and 400m distances.  For reference, the time to swim 100m is about a minute, so rowing equivalents would be 250m, 500m, and 1000m.  I believe that I will complete the test at 1000m to align better with the longer rowing competitive distances.

After each trial, a lactate reading at 1 minute and 3 minutes post exercise.  The book recommends testing at 5 min, 7 min, etc after the last trial until the lactate level starts to fall to try to get a more accurate idea of what the peak lactate level is.  Here is the graphic from the book.

Screen Shot 2015-11-09 at 10.30.09 AM

The two readings are then plotted as power versus lactate and line drawn between the two points.

Screen Shot 2015-11-09 at 10.30.31 AM

The position of the line along the x-axis provides information about aerobic fitness.  The slope of the line can be used to understand the balance of aerobic to anaerobic power.  I do not expect to get much out of the first test beyond establishing a baseline for future testing.

The thing I like about this test is that it is not as susceptible to judgement as other tests (like the Rojabo test).  Basically, since you are measuring both power and lactate, even if there is minor variation in how hard you try, the line will still give a good idea of how your fitness has changed.

So, the specific guidelines for the test:

  1.  15′ minute warmup including 5 x 10 stroke bursts at test power
  2. Trial #1:  1000m, 6K pace (~1:50)
  3. 15′ rest:  at least 10 minutes active, with lactate tests at 1′ and 3′  (record max lactate and avg power)
  4. Trial #2: 1000m 2K pace (~1:42 ish)
  5. Cool down: 10′ with lactate tests at 1′, 3′, 5′ (record max lactate and avg power)
2. Anaerobic Power Test

(Source: Rowing Faster, 2nd Ed., Chapter 6)

This is a modified version of the Wingate test.  It’s pretty simple.  Row as hard as you can for 60 seconds.  That’s it.  The key to the test is what happens in the 60 seconds.

The instructions are:

  1.  Set the erg to maximum drag factor.
  2. Setup a way to record the power for each stroke, either take a video of the monitor to review afterward, or use rowPro.
  3. Do a 10 minute steady state warmup
  4. Set the monitor for 1 minute intervals with 1 minute rest.
  5. Paddle through the first minute and the first 50 seconds of the rest.
  6. In the last 10 seconds of the rest, crank up the power so you can hit the beginning of the test period going full blast
  7. Row as hard as you can with good form.  Rate up as much as you like, as long as you are taking full strokes.  Do not pace yourself.  The objective is to pull as many watts as you can on each stroke.
  8. As you continue through the minute, your power output will begin to fade.  This is expected and is precisely what the point of the test is.
  9. After you finish, throw up in a nearby trash can, cool down and then get working on data analysis.

If you do it right, you end up with a graph that looks like this…

Screen Shot 2015-11-09 at 1.43.38 PM

Here is what you try to get from the curve

Screen Shot 2015-11-09 at 2.12.31 PM

Here is Table 6.3

Screen Shot 2015-11-09 at 2.14.29 PM

So, for me as a heavyweight man, at 52 years of age.  The target peak power is

  • (1 – 22 * 0.3%) * 1000W = 934W (Holy smokes!  That’s a 1:12 pace.  My all time best Low Pull is 1:19.0 (710W), so I expect to fall way short of that benchmark.

As with the 2 speed test.  The main idea here is to get a baseline that I can use to compare to in the future.  Development of anaerobic power is best left to the last phase  pre-competition, unless there is a lot of strength training to be done.  So, I would likely rerun this test about a month prior to competition and then again at the beginning of the competition taper to hopefully see some improvement.

3.  2K Test

Not a lot to it.  Sit down, warm up.  Row 2K.  Record the time.  Used as a proxy for VO2Max power.

4.  6K Test

Same idea.  Used as a proxy to determine Anaerobic Threshold power

Interpreting the test results

In the same chapter of Rowing Faster, they provide the following guidelines for interpreting the test results.  All of these are in terms of power.

Screen Shot 2015-11-09 at 2.27.14 PM

If the ratios are different, then the amount of effort put into the lower areas should be increased in the training balance.

Monday: 4×20′ / 1′ rest – Back to basics

Sunday:  Rest day

Monday:

Weather:  It doesn’t matter 😦

Plan:

  1. 4×20′ / 1′ rest
  2. slow start 5′ @ 2:15, 5′ @ 2:10, then 2:03 the rest of the way
  3. rate: 19-21 (on slides)
  4. lactate test at 60 minutes

Nothing unusual in the HR chart.  I increased speed by about half a second for the last 20 minutes to see if I could hold the higher power without my HR running away.

Screen Shot 2015-11-09 at 9.20.01 AM

In the first interval, you can see the steps at 2:15 and 2:10, then the rise after the step to 2:03.  I was actually pulling around 2:02.7.  Then for the last 20 minutes, I pushed to 2:02.

11-9

So, this is the third lactate in a row at or below 1.6mmol/l for a power between 185 and 190.  I’m going to target 2:02 (193W) for a few workouts to see how that goes.

11-9 lac

Tomorrow:  I will be starting a series of assessments to get a baseline before starting my winter training plan.

GPS Distance Errors

Prolific posting day for me.  I saw this on Twitter,  An academic paper about system over estimate of distance by GPS devices.

WHY GPS MAKES DISTANCES BIGGER THAN THEY ARE

There is a lot of heavy duty math in the paper and if I manage to understand it, it will take a while.  But the basic gist is that the larger the error in the estimated positions along the route trajectory, the more cumulative distance errors occurs.

Screen Shot 2015-11-08 at 1.37.45 PM

In the pedestrian example they provided, the error peaked at 2.5 meters of over estimation at 45 minutes into the experiment.

Screen Shot 2015-11-08 at 1.41.30 PM

Not all that much error, but it gives you something to think about.

How it is supposed to look…Mahe Drysdale at the Head of the Charles

I came across this over on Reddit.  I guess Mahe had a GoPro mounted on his boat during the head of the Charles.  Basically the same perspective as mine, but mounted a lot further away from the stern so you can’t see the finishes, which I am sure would have been even more impressive.

His row was at the end of the day on Saturday, when the winds had died down a bit from earlier in the day, but was still a factor.  The video shows him passing Andrew Campbell between the Western Avenue Bridge and the Weeks Footbridge.  Campbell is a lightweight and was effected by the headwind a lot more than the gigantic Drysdale.

Part 1:  Including a bit of his warm up, the start and the race through the Anderson Bridge

Part 2: Through the big turn, under the Eliot Street Bridge and to the finish.

Oh, what I’d give to be able to row like that.  It is interesting to have a video of the same race, under similar conditions, from the same perspective but with one of the finest scullers in the world doing the rowing.  It was particularly humanizing to see him take a lousy stroke now and then.

Merrimack Chase Videos

Sorry about the shaky video.  I had to improvise a mount and it had a bit of wiggle to it. I decided that the videos would look better using the youtube stabilization.  I’m not entirely sure.  Also, for some reason, the heart rate sensor decided to not talk to my iphone yesterday.  It worked fine to the speedcoach, but that was using a polar receiver.  I suspect that the bluetooth connectivity is a bit squirrely.

Truth be told, it’s not all that exciting a video.  I go under a bridge at about 5 minutes into the first part.  And the water is nasty and rough, but since I had the first bow number for the event, I had no one to pass.  I had a close call with a buoy at 1:55 in the last part.  I almost got the last guy of the Master “C” group at the end of the race, but not quite.  I think the sprint from 2:00 into that video to the end was pretty good.

The pre-start and about the first 8 minutes or so of the race:

The middle of the race, from after the bridge around the big bend and into the flatter water.

The last few minutes of the race.

Not the prettiest rowing I have ever done, but for the state of the water, I’m OK with it.  Lots to work on for next season!

Merrimack Chase – I won.

Weather:  Broken clouds.  Warm, nearly 60 degrees.  Windy.  It looks like some kind of a front went through during my race.  It was a WNW wind at about 10mph, with gusts up to 23mph.  This is a pure head wind through the first 2 km of the course.  The water as nasty.

Here is the weather underground almanac for today from a station right on the Andover side of the river in the middle of the course.  The cursor is about 5 minutes after my start.

Screen Shot 2015-11-07 at 4.33.21 PM

I was pleased with the race result.

results

I finished first among the Master D/E group.  And finished close to top guys in the Masters C group.  I know those guys and they are good scullers.

Looking at the map of my course, I am not all that happy with my line.  I messed up my approach to the bridge and it added about 30 meters to my course, or nearly 10 seconds to my time.  And I did not hug the big turn nearly close enough, that probably added another 30 to 50 meters of length to my course.  Having said that, I steered it bette rthan the guy behind me.  I think he could have beat me if he followed my line, but he went way wide around the turn.

Screen Shot 2015-11-07 at 3.12.29 PM

Since the wind was from the WNW, the first half of the course until you were completely through the turn was straight into it, and the chop was pretty nasty, so the pace was really slow.  Once around the corner, it was a lot smoother and much less wind.  Still a few gusts to contend with, but much nicer water.  The splits reflect that

In the last 1000m I was coming up behind one of the boats from the Master C group.  I wanted to take the line along the buoys on the western shore, but he didn’t really give me a good line and I ended up nearly hitting one of the course buoys.  That pissed me off enough that I cut across his stern and spinted my guts out to the finish.  I nearly caught him at the line.  I can thank him for probably a 10 second better thime than I would have other wise had.  🙂

Thursday: Taper Day 2 –> 2 x 2′ / 5′ rest (on the erg)

Early meeting, so I missed a beautiful morning on the river.  I looked at the glassy smooth water as I drove past.

Plan:  Taper day 2.

  1. 20 minute warmup
  2. 2 x 2′ / 5′ rest
    1. rate: >30
    2. pace:  faster than 2K race pace (1:40ish)
    3. on slides
  3. Cool down

2x500 Screen Shot 2015-11-05 at 9.02.04 AM

It was mercifully brief, but each interval really stung.  I pushed a lot faster than 2k race pace and let the rate really climb on the theory that the whole point is to provide sufficient stimulus to avoid any fitness loss during the taper.  No evidence that this is the right thing to do, but it made me feel like I was giving it my all.

Tomorrow:  Back on the river.  A nice warmup, a single 500m interval, and an easy cool down focusing on technique.  Then load up the boat for the race.

Wednesday: Taper day 1 – 3 x 500 / 500m rest

This has been the nicest stretch of weather this week.  Today was mirror flat water, temps in the 50s, and bright sunshine.

Plan:  Implementing a short 3 day taper for the race on Saturday.  This is based on this paper.

  1. Nice long warmup
  2. 3 x 500m / 500m rest
  3. Rate: >30
  4. Pace: faster than 2:00
  5. Work on keeping the rate up and technically clean.

The intervals stung, but only for a very short while after finishing each.  I really like to see a pace below 2:00 on the speed coach.  It’s fun to row fast.

I’m probably going to need to do tomorrow on the erg because I have an early meeting at work.  Pity.  The weather is supposed perfect again.
