Anyone have any data on how much more power can be produced standing vs seated?

Thanks,

On my SRM meter I put out almost twice the power when standing. In alot fo crits I have noticed i can almost equal my sprint watts by staying seated and hammering without standing. As far as hills go, I only stand when its over 12% for a long time, say 2 miles. Other than that, even standing at all on the pedals my power will allmost certainly double.

I did a wingate today and I'm just curious how much more power should be produced standing than seated without redoing the whole thing. You kinda answered the question by that you produce twice as many watts standing than seated on climbs... but then you throw in you can equal your watts seated in a sprint as standing. Hmmm... could be the RPM difference or just lower effieciency standing?

Thanks,

... as you probably know, climbing while seated is supposed to be more efficient than standing because the rider supposedly expends more energy standing than seated at a given speed, which means that standing is good for short bursts and changes of pace rather than long climbs. That's the Word as it has been written.

However. Like you, I've also had the interest to see more research on this subject that would study the multiple factors and variances to be considered, such as steepness of grade, weight of rider, techniques utilized, etc.

I've been personally toying with different standing techniques on my own, such as using my body weight (200lbs) to augment muscle force, simultaneous lifting and mashing, rocking the bike side-to-side. But as you say, data would be of interest; not only to compare seated vs. standing, but also to evaluate various standing techniques.

Just wondering, what were the results of your wingate??

I got 1212 watts seated or 14.1 watts/kg. A result that all in all I'm very pleased with.

... I think Doug Sloan likes to say "every tool in your arsenal".

I've watched "Eddie B" training world-class trackies at the San Diego Velodrome. The term used there is to start a sprint by standing and accelerating until your pedal stroke "gets crazy." That seems to take about 2/3 of a lap or less, with each lap 333.3 meters, so call it about 200 meters or so. After that, they sit and spin (at a power most of us would faint trying to produce). Races rarely go past 1 km at full speed.

Standing can produce explosive power, probably 2-3x what you normally deliver seated, but not for long. Most riders who have not practiced it don't know how to control it. Fixed-gear riders and singlespeeders (that's me) learn to take long climbs standing almost continuously, holding back the power. I personally find this more efficient than spinning up a hill, but I've always been a masher.

Riding singlespeed, most climbs are right at the rider's AT or LT, breathing hard, a trace of burn in the muscles. At the top of the climb, your standing muscles are typically nearly spent. Returning to a seated position switches muscle groups to fairly fresh muscle. Riding seated for a while lets the standing muscles recover. By learning to use both positions, you develop the ability to develop good power in both groups, and that HAS to be an advantage.
