Is there an optimal stroke length?

[Sandeman]

Is there a way to look back in history for my stroke lengths?
If not my last session was 1,27m and i'm 1,98m so that makes a ratio of 64%

I must add that I hurt my back lifting my old rower out of the house a couple of weeks ago so I can't catch as far forward as I want to.

Today a 60min steady state r20 @~2:07, switched to statistics page of ergData:
Stroke length: 95% 1,42, some 1,39 and 1,45, rarely 1,48.
Force max/mean: 95% 60/40kg, some 1-2kg above or below
Stroke speed: 14,5-15m/s

Height 1,77m, shins not past vertical, back feels not rounded, not even a bit...

Where did you find the statistics page in ergdata?

Hmm, statistics perhaps wrong name - real time data matches better
There are 3 pages, page 1 with basic stats and if you swipe left you get the mentioned stats. If you swipe again you get the logbook page.
I swiped to Page 2 during row to see these stats as I was interested to observe them during row triggered by this thread

Got it, I thought you had discovered something that isn't there but should be. I only use ergdata to count strokes and upload to my log book.

I think it needs mentioning that ergdata only measures the 'applied force' part of stroke length. So if OP is slow away at the beginning of the drive then stroke length may not be quite as short as 1.20m drive length implies.

I notice my own varies depending on whether I am pushing a hard (for me) pace or going a bit slower at steady state where my 'kick' doesn't apply force quite as quickly. Anything between 1.15m slow and 1.3m pushing things.

I use it for the same reason, but was interested in this stuff now

This was the reason why I listed also the other metrics, as they correlate to pace.
My stroke length is nearly the same for faster paces, but stroke speed and force must increase then as they are the factors which apply more force quicker, not longer (=more length). Or the stroke stays exactly the same and one needs to up the rate to apply more force over time and not per stroke.

ErgData gives you a value for the drive length on each stroke.

and does it store them for later analysis or do you just have to have erg data open and visible during your sessions to be able to view it?

No, there is not. You have to check at each time and making yourself an idea of your standard stroke length. Same for the force.

My better wish would be to have a Force Curve « resume ».

I have been looking for the ideal force curve a long time!Did you know about it?Everyone told me the ideal means smooth,but without a precise appearance??

Interesting topic.
Did a 30 min. ( HR average mid UT2)

Time Meters Pace Watts Cal/Hr S/M
30:05.4 6,684m 2:15.0 142 788 15

Where i just focused on the stroke length to be over 1,3-1,33 M.

Yes, stroke length is something I need to improve on ( at the catch)
