In road racing you ride behind other riders because it IS more efficent (i.e. YOU USE LESS ENERGY WHEN DRAFTING FOR ANY GIVEN SPEED). In time trialing you use all that you can give and also choose an aerodynamic position and efficent cadence to make the most of 'all that you can give'.
We are not talking about choosing the most efficent cadence here, but choosing the most efficent pedaling technique at any given power output. If I were to ride at 500 watts using a very inefficent technique, I would not be able to maintain that effort as long as I could have using a more efficent technique!
In many cases in cycling the most beneficial or optimum technique for performance is likely to be the most efficent. Obviously, the most beneficial or optimum technique for reducing back pain may well be the least efficent, however this technique is likely to have negative effects on maximal performance in a person without back pain.
Oh, and remember just because back pain is reduced doesn't mean that it will result in performance increases for 'normal' riders. That will need different evidence.
Check out the definitions of 'economy' and 'efficency' in a biomex text book, I think you will find it interesting.
I never mentioned reducing back pain, what my
pedaling does is completely eliminate it, even the worst
cases.
As you and all others know of only one way to pedal,
research to date is not on finding the most efficient
pedaling technique but rather on finding the most
efficient way of using the same basic round pedaling
style.
As for combining arm resistance with leg power and
not moving the hand/arm, it is easily explained.
Imagine you are standing upright, hands by your sides,
the front half of your right shoe is resting on a slightly
raised pressure plate and your right hand is grasping
a fixed lever handle. As you apply pressure from the
right shoe to the plate, this pressure can be increased
even further by the continuous pulling of the arm without any visiable arm movement except for the
working of the muscles and this increased pressure
could continue even if that plate moved downwards.
This is because the lines of pulling force and downward
pressure force are parallel or to put it another way, in
opposite directions. This is one of the main differences
between the two completely different pedaling techniques and can be easily done by the vital change
in the method of tranferring or directing power from
shoe to pedal with that well known Anquetil toes down
technique.
As has been already stated, this is getting nowhere.
I have no more time to waste.
