Steady State again (finally)

Thursday

I arrived around midnight on Wednesday night, and the last 2 hours of my travel was in a car through a snow storm.

I was tired form the trip.

I had a lot of things to do.

I didn’t feel 100%. The feeling that a cold is sneaking upon you.

I knew Thursday would be my only opportunity to finish implementing the Empower Oarlock  data visualization on rowsandall.com.

So I decided to skip the training and spent the evening implementing, testing and debugging Empower Oarlock data. All of you who already own this great oarlock, I invite you to register, upload the CSV file that you can export from the LiNK software and start playing.

I cannot show you any pictures, as I don’t have my own data yet. Also, you may find a few undiscovered bugs. In that case, drop me a line please. Apart from bringing power based training to OTW rowing, the oarlock records a bunch of other useful data, and I am really excited about visualizing these data for you.

Friday

Managed to get all my work work done by 4pm and drove home quickly for a Steady State workout. This time, I chose a 2000/1750/1500/1250/1000/1000/1250/1500/1750/2000 format which is exactly 15km and a bit over an hour in my version:

I rowed this as a “Just Row” on the erg, using Painsled to record the data and send it to workouts @ rowsandall.com, and rowsandall.com to split this up in the right segments after the row.

And here are the plots:

I ended at a slightly higher Work Per Stroke (“SPI”) than I started. All in all I am happy with the workout, even though I found the heart rates a bit on the high side.

Interesting how drive length makes a visible jump after 2000m, when I switched from 18spm to 19spm
I wonder why the average/peak force ratio always starts a bit higher

bokeh_plot-35
Here is drive length as a function of stroke rate. 18spm feels unnaturally low to me. 19-21 spm feels comfortable.
bokeh_plot-34
Work per stroke. The first 2km at 18spm where a bit slower (warming up effect). For the rest of the row, it was pretty consistent, albeit slightly lower above 21spm
bokeh_plot-38
Another look at heart rate. Now vs power. Is it true that in a good sub-threshold row the heart rate should drop when you drop the power? In that case I failed
