Rpw : Rowperfect for Windows Update (September 2007)
 
Hi everyone, some small fixes this time, mainly addressing heart-rate readout issues. As always, the full release notes of this version can be found below. 

You can download the software from 
rpw-without-manual-1041.exe

RPW will only record data when connected to a MKIV monitor, or a re-programmed PC interface. This implies that upgrading from CARE/DOS to RPW means getting your current PC interface re-programmed. Please contact your local Rowperfect agent for details.

Q. Can I use Rpw on a PC without a serial port?
 
A. Yes and no.  We have been able to use RPW through an USB-to-serial adapter, testing several brands and models. However, not *all* cables tested have proven to be useable. Therefore, we suggest to use a serial port when available, and only switch to a USB adapter when strictly needed. 

# Recording, and then what?

Q. Why should I record all this data for every stroke in the first place?
A. To analyse your work, real time (during the training session) or off-line (when done), and thus monitoring performance, progress and athletes compatibility. With RPW, you can analyse 2 files at the same time. To do a thorough analysis of larger amounts of data, try SEAN : Session Analysis. 

# Release Notes version 1.0.4.1 - August 29, 2007

* The splash screen will show an "About" button, when the software has expired.
* Improved heart rate read-out.
* Time and heart rate are now continuously updated when the flywheel is not spinning, approximately once every two seconds. Note: this is done ONLY when connected to the interface. That is, when a training session is in progress; NOT when a session has been finished or canceled.

* Parameter cells in the Row window are now displaying the start value for a count down session (e.g. distance), right from the beginning; NOT only after the first stroke has been made.
 

Version 1.0.4.0 - January 9, 2007

* Support for reading KkIV files has been added. Now, MKS (Session),
 MKR (Strokes) and MKI (User settings) files can be read. These files are generated by MKIV monitors with software version 0.32 and later.

Rowperfect Force Curves

Wednesday, August 15th, 2007

A group of international athletes has provided us with sample curves of their technique when training on the Rowperfect.

Here is a zipped file from which you can download them.  Most are from the DOS software and a couple are from Rowperfect for Windows software (RPW).

RP Stroke Files

the athletes include:

  • Mahe Drysdale (Hwt Man)
  • Sarah Winckless (Hwt Woman)
  • Tracey Langlands (Lwt Woman)
  • Vaclav Chalupa (Hwt Man)
  • Teresa Mas de Xaxars (Lwt Woman)
  • Greg Searle (Hwt Man)
  • Karin Scanlon (Lwt Woman)

THese can be uploadedinto the RPW software to form a template against which you can do your own training…. And if you find that you aren't (quite) as strong as Mahe, you can use the Stroker Programme in DOS to re-size the curve to fit your own capabilities.  e.g. reduce overall length by 15% and reduce overall height by 20%.

Watch Google Earth as you row….. indoors!

Tuesday, March 20th, 2007

What a brilliant idea.  As you row on your ergo, why not watch the world go by….. in real time?

There are some wonderful crazy rowing guys and girls around the world.

Fancy sculling the Zambezi, rowing Rodeo Drive, causing havoc in
China?  it's all possible thanks to a fun little plug-in and some help
from Google Earth !

Here's how to do it ….

Here's what the Google Earth Blog said.

Why not hook up your rowing machine and practice rowing your
favorite river from the comfort of your exercise room? That's what these guys did.  They wrote an application to interface between a Concept II PM3 using a USB cable and Google Earth so you can then row yourself down the river.   

This is a great concept, but could use some more innovation to make
it more practical. Right now it apparently just shows a view of the
river as you row yourself along. You could show a boat icon with your
position, show your track, put up your current speed and distance to
finish, etc. In fact, you could use the new time features in GE 4 to
show animations of your previous runs. This tool enables you to do
familiarization with a new river before you even get there in person
(the same way I use GE or a flight simulator for familiarization before
I fly to a new airport). Of course, you could also do fun things like
row the Grand Canyon, go down 5th avenue in NYC, or do the Pacific
Ocean! :-) via OgleEarth.

Would someone out there write a version for Rowperfect?  Justus is the king of the software and would happily collaborate with you, I'm sure.

Rowperfect weight adjustment question

Thursday, March 1st, 2007

We recieved this question from Nick Panza, coach at Yale University. 

We use the rowperfects a lot at my university and I had a few questions about them. 

My primary question revolves around being able to enter different weights and how that affects your splits, watts, power on the screen, if it does at all. 

For example, over a 2000m piece, if someone who actually weighs 75kilos and enters 75kilos averages a 1:25.0 split for the piece….if he did the same piece with the same settings but changed his weight to 70kilos, would his split be a lot faster?  Does the weight adjust the split or anything else?  Thanks very much for your reply. 

Nick Panza

Our reply

The algorithm behind the RP software works like this.  The power (joules / watts) you pull is an absolute measure.  If you pull 500 joules and I pull the same it is the same number and totally unadjusted for our respective body weights.

BUT the athlete's body weight and the boat class affect the 500m split score because this is a derived number. 

To answer your question about the 75 / 70kg athlete.  Yes he would go faster at 70 kg as the computer assumes he is carrying the weight of his boat plus his body mass.  If the body mass is lower the score improves for the same amount of power exerted.

I did a test of this once while training alongside a Lwt lady who was about 10kgs lighter than me (thanks Marjan!).   I tried to pull the same watts score as her.  When I did (approximately) my 500m split was about 8 seconds slower than hers. Which proves the point.

I attach a document detailing a re-verification of the algorithm done by Casper Rekers which I think you'll find interesting reading!  It still holds true from original 1991 data to today!

Rpw : Rowperfect for Windows Update (January 2007)



 
In this update

  • How do I … ?
  • Recording, and then what?
  • Release Notes

Hi everyone,

again some small fixes this time. As usual, the full release notes can be found below.

You can download the software from the following URL

http://www.row-ware.com/rpw/1-0-4-0/

You can also obtain the latest version at any time, by sending an e-mail to get-rpw@row-ware.com  (subject and message body are not relevant). This will result in an autoreply mail being sent back within 10 minutes, with the installer of the latest version of Rowperfect for Windows attached as a ZIP file.

Rpw will only record data when connected to a MkIV monitor, or a re-programmed PC interface. This implies that upgrading from CARE/DOS to Rpw means getting your current PC interface re-programmed. Please contact your local Rowperfect agent for details, or contact Rowperfect Pty Ltd in Australia (info@rowperfect.com.au).

To try Rpw with older (non-re-programmed) interfaces, please obtain the Rowperfect for Windows TRIAL version by sending an e-mail to get-rpwt@row-ware.com  (note the extra "t").

# How do I … ? —————————————————–
This months question:

Q. My old laptop seems to hang when doing long sessions with Rpw. Can
    anything be done about it?

A. Long sessions means accumulating lots of data. As Rpw stores all
    parameters of all strokes in a session, after 20 minutes (or even
    less, depending on computer hardware) the PC runs out of memory and
    processor power. There are 2 ways to prevent this to happen, aside
    from the obvious "don't do long sessions" :)
    1. Switch of the Strokedata chart in the Row window, by right-
       clicking it.
    2. Add a line to the INI file limiting the number of strokes
       visible in this chart (see release notes). All data will still
       be stored, but only the last x strokes will be visible during
       the session.

# Recording, and then what? ——————————————
Simple question: why should I record all this data for every stroke in the first place?
Simple answer: to analyse your work, real time (during the training
session) or off-line (when done), and thus monitoring performance, progress and athletes compatibility. With Rpw, you can analyse 2 files at the same time. To do a thorough analysis of larger amounts of data, try SEAN : Session Analysis.  See http://www.row-ware.com/ for details on SEAN.

# Release Notes ——————————————————

Version 1.0.4.0 - January 9, 2007
* Support for reading MkIV files has been added. Now, MKS (Session),
   MKR (Strokes) and MKI (User settings) files can be read. These files
   are generated by MkIV monitors with software version 0.32 and later.

Version 1.0.3.1 - November 5, 2006
* Right-clicking on the charts in the Row window was not possible when
   they had been set to "Empty" and the programme was re-started. This
   has been fixed.
* Running the programme on older hardware, with limited processor
   and/or memory capacity, could result in badly updated charts in the
   Row window, especially with long sessions (20 minutes and more). To
   address this, users can switch off the data chart on the right by
   right-clicking it, and selecting "Empty". Alternatively, one can
   setup the programme to just show the last x strokes, in stead of the
   whole training session. To do so, add a line "DataRange=x" in the
   INI file in the [Row] section, where X denotes the number of strokes
   to plot. The minimum is 5, meaning "always show at most the last 5
   strokes".

Version 1.0.3.0 - July 30, 2006
* Some small fixes in the Manual have been made.
* Right-clicking on the training sessions list in any of the analysis
   windows will show a pop-up menu to (de-)activate the selected
   session and to set the chart properties. The same parameters can be
   set by either (un-)ticking the check box, or double clicking the
   line.
* When connected to an old-style PC interface, an obscure error
   message was displayed (the so called "protocol error"). This has
   been improved.
* The date limitation on Rpw, which used to be approximately two months,
   has been removed. From now on, the software does not expire any
   more.
   Please note: Rpw Trial still DOES expire after a couple of months
   trial period.

Dear Rowperfect community

The Rowperfect Seminar 2006 is again on Friday 24th March the night before the Eights Head.  Our speaker is the new Cambridge University Chief Coach, Duncan Holland and he will be speaking on Seat Racing for Crew Selection.  Email us to reserve your place.

Have you read Rowing magazine?  They are asking for readers’ letters.  And this fantastic endorsement for the Rowperfect from Murray McLeod Jones, has been sent to Sophie Mackley for publication.  He has kindly allowed us to reproduce it here and also on the website – under Latest News.  We hope to see it in print in a future edition.

We were at the ARA conference in Warwick demonstrating the new Rowperfect MKIV monitor.  A couple of interesting things came about which reassured us that we are on the right track – Paul Thompson emphasized the importance of measuring distance per stroke as a measure of progress and the continued importance of core strength and posture in preventing injury came from a talk by Alison McGregor.

Rowperfect and Coxmate both measure distance per stroke so you are covered both on and off the water.  The new Rowperfect for Windows software has stroke length and distance traveled per stroke in centimeters.  The Coxmate SC reads distance traveled in meters for each stroke.  And, of course, the RP limited tilt seat is great for posture and stability training.

The FISA Sculling DVD has been selling well – every club should have a copy!  Add to this Paul Thompson’s new book “Sculling” and we have a winning combination for every coach and athlete.  Details inside for a combined sale offer.  

Happy reading and, Rowperfectly!

An extract from the chapter on Sculling Technique

Stroke correction

Sculling technique should be a focus of every sculling outing.  Perfect sculling practice makes perfect sculling.  You need to apply enough concentration to maintain your technical focus for the whole of the outing.  A technically good sculler will have listened, considered, and taken responsibility for implementing sound technique and the changes required to improve sculling.  To achieve a permanent technical change it is important to have a sound understanding of how you are sculling, as well as how you should be sculling.  A good coach can impart this knowledge.

When concentrating on stroke correction, you must be able to feel or see a difference in what you are doing and then make the necessary change to your stroke pattern.  Video feedback and modelling are excellent aids. ….
To make a technical improvement, it is often most effective to isolate that part of the stroke that is to be improved.  Both the coach and the sculler need to break the complete sculling stroke down into its smaller component parts in order to achieve this.  You can correct your stroke by exercises and then by incorporating your improved technical skills into continuous sculling.  Major technical improvements generally occur when it is possible to concentrate fully and you are not excessively fatigued.  Short sculling, or ergometer sessions, and the beginning of workouts are the best times to achieve stroke correction.

All solid advice, as we are sure you know.  Rowperfect was invited to join the ARA’s round-Britain seminar series on “Applying British Rowing Technique” speaking on how to use drills and exercises in order to apply the technique.  Email us if you would like the handout from the seminar with a list of exercises and progressions for water and land use.

Using the Rowperfect DOS software with Windows XP

An information sheet on how to alter the Bios settings to enable it to work is now available.  Email us for your copy.

Would your club like to trial the Rowperfect and the MKIV touch screen monitor for a fortnight?

We have sent out RPs with MKIV touch screen monitor out to Hereford, Worcester and Ross on Wye rowing clubs to try at present.  We have received interest from Staines, Windsor Boys School, Tees, Derby and Cardiff University.

If your club would like to join the list, you need to first clarify

  • Your club insurance will cover the RP while in your care and you are liable for any damage caused;
  • We will deliver the RP to you, but you will have to take it on to the next club on the list (this will be local or via exchange at a regatta);
  • We may use your club name in publicity.

The Rowperfect Challenge!

A letter to the Editor of Rowing Magazine.

I read with interest the article regarding the Rowperfect in the Nov/Dec 05 Regatta.  I must add my support to the article, as the machine is a brilliant piece of training equipment; I know as I have one myself but have convinced other scullers that this is the equipment to invest in.  When I procured my Rowperfect, a fellow sculler was fairly dismissive about the advantages of training on it.  I challenged him to allow me to prove its worth.  He was a Senior 1 sculler who was now moving over to veteran sculling at the age of 35, and had been rowing and sculling for about 8 years.

The challenge was that he would train on the C2 Ergo every day for two weeks and then do some videoing analysis on the water in his single and conduct a question and answer session about how the boat felt when being sculled, we would then do exactly the same for the next two weeks using my Rowperfect for the training.  The results of the first two weeks training were very interesting, he had trained on a C2 ergo for all his sculling life and from the videoing it was obvious that he had transferred the ergo skill to the boat.  In the question session he stated he felt hurried and crowded at the catch, but thought that he was applying his legs properly and coordinating the stroke correctly.  The videoing did not support this at all.  The sculling was very snatched at the catch with lots of effort in the initial phase of the drive and a burying of the sculls; the legs, body and arms were not properly coordinated and the finish was wrenched through to give a hurried finish.  The recovery was not as coordinated as it could have been and this led to an inconsistent set up of the body for the next stroke.

The results of the Rowperfect training were a revelation to him.  He struggled with the co-ordination of the technique and the firing the correct muscle groups at the right time at first, but with perseverance, coaching by me and the instant feedback the monitor gave him from the power curve; he got the hang of it.  He realized how to apply his legs and coordinate his body correctly for the drive and recovery phases.  The second set of videoing was like watching a different sculler.  The catch was much more coordinated, with a quick entry and smooth application of the legs.  The body was coordinated properly with the body and arms keeping the pressure on to the end of the stroke giving time to execute the finish properly.  The question session was also revealing, with the sculler stating he felt that he was applying power the whole way through the stroke and that he had time at the finish to get his hands away.  The overall stroke flow was better and he felt less ‘cramped up’ at the catch.

I had convinced him but then the Rowperfect had done it really, we also worked out that his overall distance per stroke had improved by 1.79 meters, so he was getting more output for less effort as he was coordinating the power properly and sculling the boat as it should be.  He now trains on a Rowperfect rather than a C2 ergo.  This was not a rigorously conducted scientific experiment, but as anecdotal evidence, it adds to the body of research that highlights the advantages of training on a Rowperfect.

Yours sincerely,
Murray McLeod-Jones

Is there anyone out there who would like to reproduce the “Rowperfect Challenge” as described by Murray above?
We can put you in touch with Rowperfect owners in your area and would like to hear your feedback.
