Hi Carla, I'm relieved the maths makes sense ! I was
working it all out from 'first principles' as I was typing and thought I had
better show my workings in case I got it wrong (to at least get part marks from
my old maths teachers for showing how I got there !). Hence it was probably a
bit too rambly to follow.
As an ex rower I have found that 10 MPS feels
like a good figure to aim for on the erg - it translates into pretty efficient
(possibly optimum) rowing and also helps provide a sense of discipline/structure
to the session. I've tended to use the Rating (SPM) and Pace readouts to keep me
'honest' on 10 MPS rather than look at the metres tick by at a particular point
in each stroke (to give the MPS for that stroke). This has proved useful when
the metres are not displayed (when using Ave Pace instead for example) on the
monitor during the row. Hence my interest in the table of SPM vs Pace
!
Good luck with the 60 min row next week, a 14K target would mean 2.08.5
pace which would be pretty awesome !
(Formula for Distance vs Required
Pace for a 60 min row is :
Required Pace (in seconds) = 1800000 /
Distance (metres)
in case you were wondering !!)
Good row Niall,
the 10 MPS Carla talks about is an excellent discipline to improve efficiency in
one's row. The following table (if memorised !) may help in sticking as close to
10 MPS as possible without watching the metres tick by each stroke
-
Rating (SPM) vs Pace (rounded) for 10 MPS
... 21 .. .. .. .. ..
.. .. 2.22
... 22 .. .. .. .. .. .. .. 2.16
... 23 .. .. .. .. .. .. ..
2.10
... 24 .. .. .. .. .. .. .. 2.05
... 25 .. .. .. .. .. .. ..
2.00
... 26 .. .. .. .. .. .. .. 1.55
... 27 .. .. .. .. .. .. ..
1.51
... 28 .. .. .. .. .. .. .. 1.47
... 29 .. .. .. .. .. .. ..
1.43
Note that if you are rating, say, 25 and allow the Pace reading to
drift out from 2.00 ( which equates to 10 MPS exactly) by easing off to, say,
2.03 then your MPS will be lower than 10. Conversely, lowering the Pace reading
to, say, 1.57 by working harder whilst maintaining a 25 rating will increase
your MPS to above 10.
The formula for calculating MPS for a given SPM and
Pace is
MPS = 30000 / (SPM x Pace) where Pace is in seconds
So
you can calculate your MPS's for your splits if you wish
(the first one
would be MPS = 30000 / ( 28 x 119.4) = 8.97 )
Congrats on the 300K, now
for 400K !
Cheers,
Martin
