Worked from home today. By 4pm we all headed to the lake. In the morning it was damp and humid, gray weather but after lunch it cleared up.
With the races tomorrow, I was conscious not to hit any higher heart rates. So I just rowed and rowed. And rowed. And rowed. Twenty strokes per minute in the single:
Around 2:20 pace in the light tailwind, 2:30 pace in headwind.
I have been playing a bit with my rowing physics model today. Trying to get the calculation of corresponding ergometer power right. I am not there yet. Here is a plot of what I am trying to achieve:
Looking at my heart rate and how the row “feels”, I would say I was rowing at a pace that on the static ergometer is somewhere around 2:00 – 2:02. My calculations give me something between 1:55 and 2:00. I don’t know about you, but for me the difference between 2:00 and 1:55 is huge. And rowing at 1:58 on the erg, I definitely achieve higher heart rates. Being an experimental physicist by education, I have no ego problems admitting that I am in the stage where theory and experiment don’t match.
(The other explanation would be that I am a superior rower and lousy on the erg.)
Bill Atkinson has, very timely, started the discussion about internal energy dissipation in rowers on rec.sport.rowing. Also today, I received an email from Marinus van Holst mentioning that in anticipation of the Olympics, the Nederlandse Natuurkundige Vereniging (Dutch Physics Society) has devoted the June issue of its Tijdschrift voor de Natuurkunde (Dutch Journal of Physics) to Physics and Sports. Of course, being Dutch, they focus on swimming and speed skating, but still this was interesting enough to order a copy. (I am a member of this society but living abroad I don’t get the journal.)
I am very excited about this. Ultimately, when I have sorted the physics and found something that I understand and is correlating well between my humble OTW and OTE results, I want to offer the erg to water power calculations to the members who register on rowsandall.com.
Racing tomorrow. It’s not exactly Oxford vs Cambridge, but it’s the fourth year in a row of Piestany vs Brno vs Neratovice Masters Eights on the Moldau (Vltava) river in Prague. Sixteen Masters rowers will be disappointed. Eight Masters rowers will feel they own the universe. đŸ™‚
