ric_stern/RST said:To expand on what Beerco wrote: when cycling your legs are constrained by the pedals in the saggital plane, and thus, efficiency varies little between untrained sedentary people (~ 18 - 20%) asked to ride a bike and elite cyclists (~ 20 - 25%).
Efficiency is related to the absolute intensity of exercise, and as the intensity of exercise increases so does efficiency. additionally, it is also related to cadence. What may seem paradoxical to some is that a low cadence is *more* efficient than a higher cadence.
Cycling is a gross motor control sport, that is easy to learn and requires little skill. additionally, research has shown that the concept of pedalling in circles is incorrect. Using iEMG analysis and force instrumented pedals, we know that better cyclists (elite) push down more and pull up less, than less good cyclists (regional) who push down less and pull up more.
Pedalling workouts, do not increase your power output, unless they're of a sufficient intensity to stress you, which would ultimately lead to adaptation. however, you've described them as very low intensity, so this is unlikely to happen.
my professional coaching and sports science advice is to ignore rubbish about these types of pedalling skills*, and just to ride the bike, in a manner that truly increases your power output.
*as long as you're between about 80 and 100 revs/min on the flat you're good to go. on hills, you may be at a considerably lower cadence, because even though Carmichael (and LA) touts the high cadence stuff for climbing, they haven't thoroughly thought the consequences through. at least for anyone who isn't able to win the TdF or who doesn't have a triple chainset.

when you say elite, who is elite (I mean in the test), obviously most of the peleton in the tour de france for instance would be elite, i bet some of the better riders pull up more than the other riders..
and there is some problems with that test. Like if the main muscle used, even if you concentrate on circles, is the quad.. therefor your going to push down more every stroke, therefor every stroke gives the quad a better training effect... Therefore the ratio of power is going to get more and more toward the quad as you continue to train, maybe even to the point that your not actually powering your pedal at all by pulling up, but you are allowing less resistance against your quad as it pushes down.
saying all elite are the same is kind of odd anyway.
the meaning of using high candence is to use your biggest strength, which is your aerobic system. (obviously if it is already hard to pedal slow, then you need to shift down to pedal faster and go the same speed/have the same power output)
you do have a good point though, some people who are very weak, like frail old ladies, might need a triple ring to be able to shift down enough to pedal fast uphill.
