Don't flatter yourself - it was frenchyge's inquiry as to whether I'd gone
any further with this that finally got me off my butt, not any of your
comments.

The lower the cadence for a given power, the higher the average effective
pedal force, so yes, if you pedaled slower the force requirement would be
higher. The 45 rpm that I used is on the low end of what the vast majority
of individuals performing such training actually use, however, and it is far
easier to increase the force requirement by simply pedaling harder (i.e.,
increase the power output) than it is to pedal even slower than that.

Whether peak force is more than, or less than, the usual ~2x the average
force will depend on how/if somebody chooses to try to modify their normal
pattern of force application. Specifically, many coaches advocate trying to
do the opposite of what you suggest during such intervals, i.e., that riders
should concentrate on "rounding out" their pedal stroke (me, I just
pedaled).

When/where (recently) did I ever say that people shouldn't do SE training?

Of course you didn't say that specifically. But you did say "it seems
unlikely that SE training would result in significant increases in muscle
size, strength, or power" and "there is really no reason to believe that
this form of training would be superior to training at a normal cadence" so
one can reasonably conclude that you don't believe "traditional" SE workouts
have much value. Is that the wrong conclusion? Either way, thanks for the
good work, and for posting something interesting to rbr.

Interesting take. Even for a fairly well conditioned cyclist, one would
expect to see some improvement in the ability to complete SE type
workouts. Over the course of several weeks, the subject would be able to
complete more reps and longer intervals. As sub-optimal as they may be,
there must be some adaptive changes taking place.

I think that you are being misled by his poor graph expansions. He said that
dropping power slightly led to greater endurance. And of course some people
can maintain pretty stable high power outputs for a long time.

Consider - crits are the most popular American racing. One of the reasons is
that it is only 1/2 hour of blasting around the course. And THAT is the sort
of thing that turns out to build huge strength and speed and consequently
reduced output endurance. So for relatively small training times your
performance takes HUGE leaps and with the busy American lifestyle that works
out well.

You definitely should, as I think you'll be rather surprised at the answer.

When I do SE training, I'm trying to condition myself for grades steep
enough that it is moderate to high intensity, so much so that my
cadence is reduced to 45-75 RPM.

So, is Dr. Coggan's finding that I would be better served by stomps, in
addition to normal endurance work?

Yes, this is my understanding of AC's post. I still see some benefit in
lower rpms especially when I am able to increase the time interval by
100%, 200%, 300% etc over several weeks. It's likely to be the 27th
consecutive day of rain here in the PNW. I rely on the indoor trainer a
lot and have several training phases/routines. I won't be dropping this
one any time soon.
Remember, science is not an accurate or complete model of physical
reality, it's just a good heuristic.

Just because you can improve at something doesn't mean that it is doing you
any good.

Perhaps a better way to characterize it is, "Just because you can
improve at something doesn't mean that it is doing you optimal good."

I think SE is similar to performing 8-12 reps in weight training. It's a
compromise of strength (1 rep max) and endurance, but not optimal for
either.

I hope he's got Perl installed.

Well, what are the likely physiological adaptations that enable
increased time intervals?

Your article debunks strength and maximal power improvements but quite
frankly, I'd be surprised at anyone doing SE for those reasons.

Since you specificaly mention physiological adaptions, don't forget there
are likely to be mental adaptations at the same time.

I could speculate, but ultimately the question is, does it matter? Obviously
it does if for some reason (broken derailleur cable? excessively high
gearing?) you're forced to pedal for extended periods at a markedly
suboptimal cadence, but otherwise, who cares?

Those climbing at 8 mph with a 39/23 or a 39/25. These are not uncommon
and not everyone does SE at 45rpm. How many of us climb longer grades at
75rpm with a 39/23? Did anyone check the cadences going up Filbert St?

Other than the motivation to better the previous workout, what else
could there be?

Anybody climbing for *extended* periods at <55 rpm - which is what SE
training prepares you to do - is waaaaaaaaaaaay overgeared.

Learning improvements in pedaling techniques for the specific effort,
understanding the time intervals more precisely for energy expenditure,
learning optimal rpm for the interval, familiarization with the roads used
for the interval (if not on a trainer), learning improvements in
between-interval recovery, learning to use upper body more efficiently, etc.
