Torture Variations

It’s one thing that we regularly torture our bodies to misery. Let that pass. But torturing it always in exactly the same way, that goes too far.

So even though I keep coming back to the interval sessions from the Wolverine Plan (and the Pete Plan), this year I make an effort to vary how I row them. Today I tried red-lining (or perhaps purple-lining, looking at my heart rate). Next time it may be positive splitting. Or do a full out 2k in the first interval, then try to minimize the damage in the following ones. The method behind the madness is to avoid staleness, and there are even training theories based on physiology that support this. Surprise your metabolic systems …

The target was 1:52.9 which didn’t seem too hard, but I have come to respect these 4x2km sessions. You cross the line and suddenly you are at risk of not finishing the session.

4x2km24x2km1

The pictures tell the full story better than the summary table. Basically I went into each 2km with 10 hard strokes at 1:40 pace, then slowed down. From the second interval onward this left me gasping for air with about 1890 meters to go. Then I would try to recover. At the half way point I did 10 hard strokes (1:47 pace), and with 500m to go I would do 50 hard strokes (1:48-1:50 pace). The final interval was of course a special one, with everything one or two seconds of split faster and a crazy acceleration in the final 500m, to squeeze out everything.

Average pace: 1:51.3. Nice. Haven’t done this session this fast before. In the 2014/15 winter, I managed 1:51.6.

That brings me to my final thought of the day, on steady state intensity again. Since I started measuring lactate I have started to think I can increase their intensity to 200W. One thing is to stay below 2.0 mmol/L in these sessions, but another requirement will be that the steady state intensity is low enough that I can be sharp for the harder sessions.

Steady State – further lactate figures

Saturday

Weather not good for rowing. Some ice along the banks. Cold water. Also, I promised Romana (who is struggling with a cold) that I would take her training today. So it was a very slow run from the rowing club with the girls. I tried to improve their running technique. A couple of breaks for stretching.

Sunday

A week ago, I did the first serious lactate testing. Today I played with the thought of repeating it at slightly higher power settings, to get some more info about my lactate curve. In the end I decided to not do 8x10min but 4x20min, to save strips and reduce the rest. I have the feeling that my lactate level goes down quite quickly and 2 minutes rest on 10 minutes exercise seems quite luxurious.

2k of slow warming up (2:15 pace) and then into the main event:

4x20b.jpg

First 20 min at 180W to get into the groove and get a data point around the power where I had minimum lactate last Sunday. I measured 0.8 mmol/L.

Then up to 200W. Today it felt like a very easy intensity, but I guess doing this after 20 minutes at 180W my aerobic engine was running at full speed and not yet tired. The result: 1.4 mmol/L. Nice.

Up to 210W and a few minutes into that row I knew I should expect a higher lactate level. The breathing got heavier, but more importantly my splits began to swing more, between 195W and 220W, instead of staying within a few Watts of the target. I had to focus more. The result: 1.9 mmol/L.

The original plan was to do the final 20 minutes at 220W, but I didn’t feel like it. Instead, I decided that holding 210W and looking at the lactate and HR levels would also be an interesting result. The row didn’t feel harder than the third interval, but still I got a very interesting (and comforting) result: 2.2 mmol/L.

Here is the graph. I plotted the additional data points over the 8x10min step test of last week.

4x20a.jpg

Even though I changed from a 10 minute based step to a 20 minute based step, I think the results are very consistent. It also looks like 200 W is really the level that I should do my steady state, if I follow the paradigm that one should do steady state below 2.0 mmol/L.

So all  in all I start to have more faith in my lactate results and will do 200W steady state for the coming week or two. I am really happy to have established that my lactate level can go above 2.0 on 210W steady state. I also liked how the level kept increasing in the second interval at 210W. Kind of suggests that 210 is above lactate steady state.

So 200W it is. Probably 3x20min during weekdays and 4x20min in the weekend, measuring lactate at the end.

Sad Mixed Quad

P9130181.JPG

P9130190.JPG

The mixed quad we rowed in Hazewinkel, at the Masters Worlds. Here’s what I wrote on my blog on September 16:

It was Lubica’s first international race since the W4x final at the Barcelona Olympics, and she was thoroughly enjoying it (and also admiring the strong guys in the other boats). The officials did a fast start “because of the weather” so it was Attention – honk and off we were. We had a fantastic start and were rowing right in front with the Polish and the British, and the Austro-Hungarian boat. One German boat was right behind us, followed closely by Chile. The second German boat closed the field.

[…]

With 400m to go I called for another push and I think we were briefly in the lead. The Polish started to push away and Romana, feeling a possible victory, called for a final sprint. In the final 250m I believe we rowed half a length behind the Polish and one or two meters in front of the British.

Honk – The Polish were in

Honk Honk – The British and us. I immediately knew they were a fraction in front of us.

Recently, Lubica went on a running training with a friend. During the run she started to get a very strong headache. Then she started to vomit. An ambulance was called. Turns out it was a stroke. She is still in hospital but miraculously recovered fully and is now getting stronger.

Doctors told her she should never do sport again.

She told us she will take up painting. I admire her positivism. Not sure I want to row a mixed quad next season.

Strength & innocent number play

Today’s session

Strength training today, preceded just by a prolonged warming up on the erg (3km at very easy pace).

The same set as last week.

  1. Pull ups – 10/9/7
  2. Pistol Squats with a dumbbell – 15/15/15
  3. Dorsal raise on Gym Ball – 15/15/15
  4. Squats – purple bodylastics band – 15/15/15
  5. Crunches & twist with dumbbell 10/10/10
  6. Squatted row with orange bodylastics band  – 15/15/15
  7. Lunges with dumbbell – 15/15/15
  8. Breast press with black bodylastics band – 15/15/15

The bold is where I went up a notch in terms of resistance. I need to find a way to increase the resistance on the leg exercises. I’d like to work in a 10-15 rep range, lowering the resistance if I can’t do 3×10, increasing it if 3×15 is achieved easily.

I feel I am nearing the end of the first “block” of strength training and need to start defining the second block.

Some play with numbers

51vvia3k-gl-_sx376_bo1204203200_

All the lactate measuring has stimulated me to reread a physiology book I own. In chapter 2, “fuel for exercising muscle”, I found an interesting figure that indicated the “typical” maximal rate of ATP generation (in mmol ATP/kg dry mass/s) for the different energy pathways, as well as the maximal available energy.

Assuming 7.3 kJ/mol that can be released from ATP, of which 60% goes to heat directly, and assuming a mechanical efficiency of 25%, a 72kg LW man should be able to produce 630W for about a minute. (I am ignoring the PCr pathway.) Assuming that on shorter rows (<500om) the average power from glycolysis is determined by the maximum available energy through glycolysis, I am able to make a crude approximation for the power and pace dependence on distance rowed.

The blue dots are the Nonathlon target pace/power for my age and weight group. The black line is my prediction.

I am amazed that this crude calculation even ends up in the right ballpark. Sometimes calculating things seems to work. My calculation also gave as a result that during a 2k, roughly 85% of the power comes from aerobic energy pathways.

Of course a couple of things are wrong. First, the nonathlon values are an average over age group records. They don’t represent one typical rower. We all know that there are sprinters and steady state rowers. Second, I have no model for the decline of the power from Aerobic processes as the distance increases, so my prediction. is too fast for any distance above 10k. It is also interesting that the 2k is faster on nonathlon. Could this be because the 2k is the standard distance? Finally, the balance of the different pathways as a function of power is individual and much more complex than my crude model.

Bike, Steady State & Experimenting

Wednesday

No training. Took the 7:40 train to Prague. Worked at our Prague office. Then had a nice dinner down town with my old rowing friend. Walked through Prague Old Town after dinner, talking about the old times.

Took the 8pm fast bus back to Brno, arriving at the bus station at 22:15, at home and in bed by 23:00. I read an interesting article on elite athletes in the bus. Will talk about it later.

Thursday

A long day at work. Then I cycled home:

Namiddagrit 11-26-2015, Heart rate.png

About an hour after a light dinner, I headed down to the erg room. I prepared two lactate strips in the cold (5-8 degrees C), next to the erg, and left two lactate strips in their container in the kitchen (21 degrees C).

Did a 2km warming up. I didn’t feel top form, despite the resting day. I even suspect a light head cold may be coming up.

The original plan was to do a 60 minutes, but I convinced myself that my experiment would work at any lactate reading, so a 40 minute exercise would be OK.

I rowed for 40 minutes. It was not nice. My heart rate was higher than usual. It felt hard. I had to stop after 17 minutes to get my audio going again (a 30 second stop only, just switched from “lecture” to “radio”).

40min.jpg

Average pace 2:03.7, 185W.

The plan was to do a lactate reading immediately after the row.

Unfortunately, when I stopped rowing, I got unbearable cramp in my right calf, so I spent the first minute in pain before I could start preparing for a lactate reading.

20:22 After exercise. Cold strip. Cold meter.

I did an easy 1km in 2:19 pace and took another measurement.

lactate 002.JPG
20:29 After cooling down. Cold strip. Cold meter.

Then I went upstairs to the kitchen and did a measurement immediately with one of the strips that had waited in the kitchen.

lactate 003.JPG
20:30. Warm Strip. Cold Meter.

Then I washed my hands with warm water and did another measurement.

lactate 004.JPG
20:32 Warm hands. Warm meter. Warm strip.

After that I took a hot shower. I mean hot. Really hot. I usually end showering by gradually lowering the water temperature until I shower off cold, to stop sweating. This time I didn’t. After the shower I took a final measurement, from my second container. My 26th Lactate strip this week.

lactate 005.JPG
20:48 Hot hands. Warm meter. Warm strip

In conclusion, I don’t think it is detrimental to keep the strips at 5 degrees. I have to believe that my 26 lactate measurements of this week were real, at least to withing 0.5 mmol/L. I think the increase from 0.6 to 1.1 while I was standing in my kitchen can be explained by the muscle lactate being cleared, temporarily increasing blood lactate.

Still leaves unanswered the question what my good steady state intensity is. I am afraid 200W is too much, but let’s see how I think about it a week from now.

5x1500m

Ben Redman posted a link to an interesting series of articles on endurance training in his latest blog post. Great reading to stimulate thoughts on rowing training for time pressed people.

My ride to work this morning was a bit slower than usual, because it was mighty cold and the mist was freezing to some sections of the road. I didn’t fancy a fall so I drove carefully.

Riding my bike I got cold hands, which made me think about my super-low lactate readings of the past two days. I guess my difficulty to get good blood flowing is to do with the low temperature in my rowing basement. The thermometer on the wall indicates something between 8 and 12 degrees C.

I also expressed fear that the low temperature might cause the readings to be lower than normal.

I posted these thoughts on the Lactate training thread on the Free Spirits rowing forum. By the end of the day Boris (“dr3do”) had responded that indeed according to him lower temperatures give lower readings and I should do my measurements at normal room temperature.

Then I made the mistake of posting a response before thinking, and as any new convert going through excitement, expectation, disappointment and frustration, I overreacted. On a public Forum. After 20 years of being on the internet I should know better.

Anyway, I apologized and I hope everything will calm down and be back to normal.

This low temperature thing is a bummer. I love to train in my chilly basement. To get the facts, I moved the thermometer to the basement floor where I prepare my lactate strips:

lactate 001
Temperature near the ground

Indeed, lower than the 8 degrees measured on the wall.

On Thursday I will do an experiment to confirm (or, hopefully, falsify) my fear. I will take two strips to the basement and leave one prepared in a heated room. I will do a 60 minutes steady state, and take a lactate measurement immediately after. Then I will do a 1km very light cooling down and take another measurement. Finally, I will walk up the stairs and take a measurement with a  warm strip. The two last measurements should be close. If the “warm” measurement gives a higher reading than the second “cold” measurement, I am in trouble.

Today’s training was a good old 5x1500m. Target pace was 1:50.7 which I was not looking forward to. At least I was able to channel my forum faux-pas frustration and focus on the splits.

Here’s a picture of my erg room wall with the scores on the doors:

lactate 004.JPG

The scribbled equations were written during the breaks of the 5x1500m. I was thinking about enzymes and the temperature dependence of their activity. Being a physicist I couldn’t come up with anything better than something looking like an Arrhenius equation. That doesn’t bring me any further because I don’t have a clue what typical activation energies would be for enzymes, let alone if they follow Arrhenius equation type behaviour. Also I would have to guess about the temperature in the strip. The plastic housing looks quite a good heath insulator. Then you pour warm blood into something that is probably around 5 degrees C. We are looking at a temperature difference that is probably a bit smaller than 294K – 278K. Basically if the reaction rate would half between these two temperatures, then the activation energy would be 31 kJ/mol. However I am afraid that with enzymes as a catalyst, things are probably not so simple.

May look into it but I fear the experiment is a more useful way to determine the effect.

Tomorrow is a resting day. An old rowing friend has a business trip to Prague, so I will join him for a beer and a dinner. Here is the two of us rowing the double in Amsterdam in 1993. I am the stroke rower and Ele Jan is the bow.

Some cool pictures

When I am not running, cycling or rowing somewhere, I do some actual work. And sometimes that actual work includes doing flight tests.

Here are some cool pictures of the plane taken a few weeks ago, and some less cool pics of me in my non-training-gear. The location is Brno airport.
