Re: Optimal drag factor

Does cycling have well defined optimal gears? (ie. if you know someone's power and body dimensions it is possible to get the optimal gear and cadence frequency?) The problem with rowing is that there are too many variables to be able to state any general rules. Beginning with a general rule of thumb...

Re: Watts versus pace

The PM measures Watts...power exerted by the rower to spin the flywheel. The situation is reversed. The PM measures speed and converts this into watts. You can notice this when decelerating or accelerating which requires respectively a little or a lot work but the watts displayed is more like relat...

Re: Watts versus pace

The PM measures Watts...power exerted by the rower to spin the flywheel. Pace/500 calcs directly from Watts and a formula with a constant that someone picked so the time shown was about right for the effort. Author in link below says "Ergometer readings have to be more or less realistic and to moti...

Re: Diet for Endurance Rowing

You basically need more energy. + + + There is some research telling you should shift the focus toward carbohydrates but you don't need to do this as drastically as many coaches and fellow athletes preach. + A little bit less strong supported is a need to take care of some minerals and vitamins.

Re: Compression

I suggest you first try to work out to get a feeling of compression at large knee angles. In my opinion compression has to do with a dynamic movement of the muscles and not with a static position of the limbs. I am sure that a small knee angle might make you feel like working hard (because it is he...

Re: Compression

i completely agree and that is what i have been working on, however, i am a flexible individual and i do believe that it is pure geometry that is preventing more compression. Would it not be beneficial to raise the heel cups there for allowing more room for thighs to compress to the heels? this wou...

Re: Njord promo (inclusief concept 2 sluikreclame ;))

Gespierde lichamen zullen volgens mij altijd goed werken. Wat mij nog opvalt is dat het stukje tekst roeien bij Njord nogal kort is. Die boodschap mag wel duidelijker worden gemaakt ook al is het maar beperkt tot 30 seconden. Uit eigen ervaring weet ik dat mijn eerste roeistapjes op de ergometers va...

Re: Compression

not my best body position buy compression is about what it is. Some people focus a lot on body positions. They almost row like robots. Your position if fine however. Maybe you focus on the wrong parameter. The feeling that you don't have compression may be due to a wrong timing of muscle force. Com...

Re: Dynamic vs Stationary

First you said that the delay is good on C2 machines and in the next paragraph you're trying to say there is no delay or it's bad. Which one is it? http://l.yimg.com/us.yimg.com/i/mesg/emoticons7/106.gif John, you need to differentiate. First I started to say that the clutch isn't the relevant part...

Re: Dynamic vs Stationary

The reason for the differences at the catch between the C2s, Oartec Slider and Rowperfect is due to their flywheel clutch mechanism. The Rowperfect flywheel clutch is designed to give a feeling of instant resistance at the catch. Whereas the C2 flywheel clutch has more give in it. The Oartec Slider...

Re: Dynamic vs Stationary

Nav, I'm not sure how you row but I've always been taught to place the blade in the water just before you reach full compresion at the end of the recovery. Not after you've reached the catch position, which is how many people row inefficiently. There can be a large difference between the way people...

Re: Compression

It is important to get your butt as close as possible to your ankles to obtain optimal length at the catch. There are two things that you can do to help . Firstly make sure your feet are set up as low as possible in the boat. Then add a spacer approx. 1 cm between the seat and wheels to raise the s...

Re: Njord promo (inclusief concept 2 sluikreclame ;))

Ik vindt het camera gezichtspunt een leuk idee maar de muziek en edditing vindt ik wat minder. Bijna nog wilder en onnavolgbaar dan de henley scene uit the social network. Het lijkt beter te passen bij plankenkoorts. Ik ben meer gecharmeerd van de video voor 2006. http://www.youtube.com/watch?v=l3x7...

Re: Dynamic vs Stationary

The zero on the abscissa is (probably) where the flywheel starts to accelerate, so after the slack has been taken up. 2 cm to reach say 2m/s handle speed implies a handle acceleration of around 10g, somewhat unlikely, from v2=u2+2as. 1g acceleration to 2m/s needs 20cm; plus any mechanical slack. Wh...
