But I have no reason to doubt the result.
The abstract indicates that maximum cycling power is related to lean thigh volume (muscle mass?) times optimal pedaling rate (optimal cadence).
Seems to support my points.
For those who are not bored with this discussion:
The above abstract obtained the results using inertial load cycle ergometry. This is a 3-4 second power number. It is hard to compare to the standard 5 second number.
Critical 'taper' program for peak competition promote increases in 'neuromuscular-power' ... Using a special power ergometer ... During the tapers maximal power increased 10-12%.
Ignoring the possible equipment problems it appears one train to the test and produce non-typical results.
These are just my observations based on trying to understand the abstract.
Considering that I was on Jim's dissertation committee, you'd better not doubt the results.
As for your other comments:
1) of course maximal neuromuscular power is related to lean thigh volume - it would be surprising if it were not. Your claim, however, seems to be that sustained aerobic power is a function of strength/muscle mass, which is an entirely different question. In any case, these data clearly demonstrate that even young boys have sufficient strength/can generate sufficient power to, say, set the world hour record - they just can't sustain it. (A point, BTW, that Dean Golich, Lance Armstrong's go-to exercise physiologist for the last couple of decades, made repeatedly at the 1st power-based training seminar in Philadelphia back in 2001 or 2002.);
2) the data presented are actually power for a single pedal revolution - however, not much fatigue occurs in the first 5 s of exercise, such that the data are in fact quite comparable (and not "hard to compare" as you incorrectly claim);
3) the effects of tapering have nothing at all to do with the question at hand, so please don't attempt to obfuscate the issue by bringing it up; and
4) in another study, Jim (working with the sports scientists at the Australian Institute of Sport) has demonstrated that maximal neuromuscular power as measured using his (not! Coyle's) inertial load method is essentially identical to that athletes can generate when pedaling their own bikes.
These are just my observations based on 35+ y of trying to understand the functioning of the human body during exercise...
