Actually, as Pace does down, the Watts go up. But that's a minor detail. :?

Right. :D
No way is pace proportional to Watts; as Watts increase, pace (which is a time for a given distance) gets smaller, so it's inversely proportional (in this case to the cube root).

:shock:

On the C2 erg, as the Pace goes down, the Watts go up in a proportional manner.

Thus the values for Pace and Watts are directly proportional to the other. :D

Thanks James, it was late last night and I was just winding down from work. Yes, proportional to the inverse of the cube of pace.

John's just screwing with all responders, because he knows he's wrong.

By the way John, you didn't answer the Schmo question.

1:15 pace vs 2:30 pace
(75 sec v.s. 150 sec)
830Watts v.s 104W

Do explain. Feel free to use full power Ruppian Fuzzy Logic.

You made this statement earlier in the thread. You then directly quoted with apparent approval the following:
If two quantities are in direct proportion, it means that as one increases, the other increases by the same percentage.
So by your own statement, if I increase my Wattage by 100%, my pace should also increase (or decrease, depending on your phrasing) by 100%. This is very clearly what you're saying, and it is demonstrably wrong.

Cheers, Paul

PaulH,

That was not my statement, but a quotation from the web site that was posted by Bill.
if I increase my Wattage by 100%, my pace should also increase (or decrease, depending on your phrasing) by 100%.
Your statement is wrong, because they don't need to increase by the same 100%.

I normally veiw the force curve while rowing trying to keep the curve in the correct form. I never view the watts. Im not sure what I should be looking for. Is there a typical zone that I should be striving for? do the watts increase the harder that I pull? How can I use the Watts to increase my 2000 meter time?
To get away from JR (and his bizarre maths and interpretation of other folks posting) perhaps we should answer the OP's question.
Is there a typical zone that I should be striving for?
Train to heart rate, find your UT2, UT1, AT, TR and AN heart rate zones. For example, do lots of long steady rows at UT2 (three sessions per week), do lots of intervals (two sessions per week) and a hard 10K on a Saturday.
do the watts increase the harder that I pull?
Rowing is 65-70% pushing with your legs. If you push harder the recorded watts will increase.
How can I use the Watts to increase my 2000 meter time?
You can't easily do that - it's simply an indication of how much power you're putting into the system. To improve 2K time you need to train longer and think about working to a training plan.

I never use the watts display. I always have the PM3 set to average pace.

JR is wrong 98% of the time.

And I'm just a little sissy boy, sissy boy, sissy boy. :lol:

Train to heart rate, find your U2T, TUZ, ATP, TRQ and AN ARN ART heart rate. Put your finger on your nose, your hand on your toes, grab your tail with your teeth, now run around in a circle. Do this three times a week at U2T, AtP, An TRQ XYZ. This what I do and I eat lots of dougie biscuits too! :P This doesn't work for me but try it anyway. :P

Rowing is 65-70% pushing with your legs. John Rupp taught me this but he is faster than me so ignore him. :?

I never use the watts display. John Rupp taught me this too. :cry:

Please ignore him and listen to me. :(

What's your next question. :lol: :lol:

When are you going to row a 2k time and put one in the rankings.

Since you haven't done one in the last 3 years.

All that sloppy 10 p.s. doesn't seem to be helping you all that much. :lol:

Hmmm. I guess you think I am someone else.

I've only been erging for a bit over a year. I've posted all of my times for the short time I've been erging. I've competed twice at Ergomania. What does 10 p.s. mean???

I was a math and physics tutor for several years and have a masters degree in electrical engineering. So reading your "new age" math finally drove me to drinking....er posting.

I am a current world record holder and a world champion, but not in rowing or keyboard racing.

Ciao
