people used to claim an old bungee made it easier to pull better scores. -marc In theory, the energy put into the bungee is recovered by helping pull you up the slide. But "the difference between practice and theory is much bigger in practice then in theory". (not sure who said that originally. I d...

These would be two separate effects. The power required to move the body up and down the slide is not measured by strain on the chain. The 25W would have to be due to either losses in the chain and the shock cord, or due to an inaccuracy in the power calculation. (As long as the inaccuracy is repea...

I remember reading somewhere that someone measured the power into the erg with strain gauges on the chain, and determined that the true power applied is about 25W more then the monitor reading. This is in addition to the wasted energy moving up and down the slide, and the intermittent nature of the...

Thanks for the Normalized power info. I did look for it but the web sites I found were rather vague. I wonder if the formula is emperical or if there is some theoretical reason that it is the 4th power. I assume they are taking 4th power of the power-- which would translate to the 7th power of the ...

Male Date April 2004 Time 6:12, Weight 74kg (Last ergo before state titles) The real record though was hitting 100kg within 6months after stopping lightweight rowing after state titles. Now 2007 just started training again 95kg, done no gym since 2004, pulling 7:14. Why did I stop training if you c...

Where does the ^.67 come from? Bicyclists use watts/(Kg of body weight) which is the same as your formula without the ^.67 the .67 comes from the increase in drag in a boat (water resistance) that accompanies an increase in weight. it's not a 1:1 correlation- instead, drag varies to the 2/3rds powe...

I certainly didn't mean to imply there was anything wrong with your attitude! just that the "headroom" for improvement it different for each person. depending on ones age and experience, the amount you can hope to improve differs. and for very well-trained masters athletes, the only real hope might ...

there's a big difference between the development of a junior or young adult and a masters age athlete with a history of regular training. the former may be expected to grow by leaps and bounds. but the older you are and the more well trained you are, the harder it is to exceed previous personal best...

I really don't know how well running and rowing can correlate. but here's a prediction and you can find out how accurate it is. according to online calculators I looked at, your 10k would correspond to a VO2 max of about 58.4 (based on an estimated 8:48 1.5 mile run). According to the Fritz Hagerman...

what sort of sporting background do you have in your recent and distant past? basically- people respond to training differently some are naturally fast responders, and some are slower. also, the more and higher quality training you have as a background, the less you can expect to improve (i.e. you a...

yes , I agree, we are all pretty much on the same page. :) marc Orc, If you read everything carefully, nobody really disagrees. Paul, I just realized I over stroked my 500m time. My 500m time of 1:37.7 was at a 39-42, but my 2K pace of 1:47.7 was at 30-32. More indication that my strength is lacking.

I thought Paul's law was brought up for use as a predictor of 2k erg pace. As in- "I have an erg race in 3 weeks, and I pull a blah-blah for 5k. how fast should I go for my 2k?" Maybe the formula will work well for the rower in question, and maybe it won't. And maybe you would conform more to the id...

It does seem like a fairly useful guide, but a lot of individuals won't conform to it well. So, the rule of thumb may be a good starting point. but mis-judging your pace even by a percent or 2 can make a huge difference in how your race goes. Presumably if you are an elite rower, you have been selec...

that guideline would have worked pretty well for me- my best 500m was about 12.2 % faster than my best 2k pace. that was years ago and I have no idea what I could do for 2k now (except that it would be much slower :( ). I might use that 500m to get a sense of where my 2k might be. marc KK68, I think...
