George, There's a contradiction between your 500 time (87s) and the 4x1k times. No doubt because the latter were sub-maximal. Even using a -12% protocol (i.e. watered-down French which would say -10.5% speed with respect to a 500 test), 1:27 points to 6:35. 12% off your 500 time means 32% less power...

Dinodi, At a guess I'd say you are pulling a short stroke. This can be deduced from your low power and high rating. The power we put into the flywheel is the product of handle force x net stroke length x rating. For mechanical reasons on the erg there is a loss of length at the catch and loss of pow...

To get any results at all, you need to row correctly and put work into every single stroke; technique in other words. There are some videos around showing what a very good sculler (Xeno Müller) does. The objective of rowing is of course to shift boats fast with as little effort as possible, not to i...

The erg is mainly for CV training, so I set the df at a value (130-140) that lets me carry on for a long time with what I think is an efficient i.e. long stroke. If the df is too high, you can't move the flywheel, so do no work; if it's too low, you can't catch up with the flywheel, so also do no wo...

Usual 9k in about an hour with lots of stops, roughly every 5 min. Water dead flat, no wind. But someone had laid out a 1k course with buoys at 250m and couldn't resist: Buoys hit: 1 of 5 Strokes 100 exactly Pauses: 1 about 10s, thought I was going to die at 750 Time to 1k 4:42. Finished at 28; most...

I scull mornings on my lake when there's no wind. I'm 65, 85kg now. Yesterday it took me 51 minutes for the length (4500m according to the map) and back, sculling at 18 and doing 3-4' pulls starting every 5'. This is as much as I can do, despite sawing about 2" of the end of the C2s - HR goes up by ...

HU, To calculate a target 500m time (to be reached after N years studying technique and training) note that the best lightweights can pull around 7W/kg for a 500 test. My best is little more than 4W/kg; I'm 65, 87 kg. Presumably you can get nearer the 7W/kg target. Another way of doing some sums mig...

Topic: slides?
Replies: 78
Views: 19378

If you're interested in sculling, then I think it's best to use slides. The catch characteristic on a fixed erg is so different (sloppy) to that in a boat (instantaneous), that I find I have to use two different techniques. For fitness only it doesn't matter. As to whether slides are faster, the que...

I wonder why so many seem to think (hope?) keeping fit could cause backache, depress immune systems or whatever, and lead to illness, rather than cure the lot. Just an excuse to use the sofa? I've been at rugby, swimming and rowing since I was 11, and never saw any correlation between hard work and ...

If you're the right shape, stop worrying: maybe the extra weight is muscle. On 2h/6days, it wouldn't be surprising.

Those docs could well be looking at your BMI only which is around 26, when ideal is said to be 21-25. Not sure if it's the same for M and F.

Both 4.4 W/kg. Well done.

R (in W/kg) = 2.8 x (2000/2k time in seconds)^3 / (pounds/2.2).

The bit you describe is the handle hook. The chainguard or guide is about 12" further forward and is the rectangular gasket around the vertical slot the chain passes through. Suggest you have a look at the C2 sites for style videos, or http://www.invernessrowingclub.co.uk/personal/xeno/xeno_erg.html

I said it's one way; no obligation. What the French Rowing Association says and C2 reprinted in their Manual is good enough for me. It worked too. We can all do just what we like, and presumably change our minds when we find a better idea.. So if you have one, tell us: what ratio, or other method, w...

JJP, If you don't do a lot of sprint work, so don't know what 2k pace you can maintain, one way to estimate it is the French protocol. It splits the problem into two: what's the basic pace to use; what's the race plan to use. Do a flatout 500 3-4 days before the race, then go 10-11% slower average, ...

You're pulling very short. So first thing to do is warm up well and then make sure your stroke is long. Try touching the chainguard at the catch, then maybe back off an inch or two according to your height and geometry. Finish with a slight leanback, back straight, forearms level and your elbows beh...
