I think I read in one of the RCN back-issues that certain 'bents
naturally provide an abdominal workout! Anyone notice?? I can't
remember which design, though for some reason I'm thinking low-racer.

Throw up is right. I've never thought about this before... when your
nose runs on a regular bike, it just drips away harmlessly. Do
recumbent riders have to contend with snot streaking across their
faces?

Another observation that really has nothing to do with your post: the

If you want to see a rowing bike in action, go to the following page and
click on "Course Future-Bike à genéve 2002"

http://www.m5france.com/Video.html

Also included: several lowracers (RazzFazz, M5, Birkenstock) and a
back-to-back-tandem.

A Thys rowbike was the first recumbent finisher in a recent

That device's maker claims that it provides a total body workout, not
just abs. In my area, it would merely provide frustration; between
the mower-jamming oak twigs and the lush mixture of grasses, a
human-powered reel-type mower is a device that will soon have the user
calling a lawn service. (I've seen people buy them around here once
in a while, but they swiftly discover that a week's worth of rain will
create a level of grass growth that such a mower is unable to
address.)

I don't know the particular "row bike" previously mentioned,
but I do know someone who owns a Rowbike brand one
(http://www.rowbike.com/). As far as I know, Rowbike does not claim
"superb aerodynamically qualities". In fact, they do admit/claim
their bike:

- Burns approximately 50% more calories than ordinary biking
- Provides nearly twice the cardiovascular benefits as ordinary biking

It definitely has a learning curve associated with it. I saw the
owner ride it and two other people try it. I declined to try it... %^P

The other one cited has a much less upright position, and more closely
mimics the rowing position and technique used in a racing shell. As
is almost always the case with advertising claims, they're probably
puffing up the description quite a bit with glittering generalities
and misleading or invented "statistics", but my impression is that of
the two, the Rowbike would be much slower.

Yes certainly slower, by design! %^)

The claim of burning 50% more calories than ordinary biking
is an interesting keting claim. Easy to accomplish the same
thing with an ordinary bike and intentionally dragging brakes! %^P
Full body workout, is the better claim for RowBike.

One presumes, a bike design that could efficiently recruit more
muscles for propulsion could be faster than a bike that employs
fewer muscles. It's the efficiency issue that's challenging, but
the laid-back Thyes rowing bike tends more in that direction
than the RowBike, almost certainly.

I wonder, is there's anything in the periodic use/rest cycle of
rowing motion that might also improve rider power or endurance?

Yeah, 50% more relative to what? By comparison to the number burned
over the same speed and distance? That would certainly be an
admission that would send people off to the other products in a hurry
if they thought about it. Besides, it's been pretty well esytablished
that the limiting and determining factor in how many calories get
burned is the engine, not the device; if the rider wants to achieve a
higher output, *any* bike will facilitate that.

Or just go faster!

>%^P
>Full body workout, is the better claim for RowBike.

Even that doesn't really look valid; the legs flex very little, and
the motion doesn't look like it would do much with the abdominals
either. To me, it's a back-and-arms beast, and doesn't even get to
all of the muscles in the arms. It it used a push-pull resistance,
they'd have more of a basis for the claims.

That's my impression; the Thyes uses more than just the arms and back
for motion generation, and the laid-back position seems likely to
present less drag as well. Of course, the cardio limit will still
determine the maximum absolute output that can be achieved, and
bringing more muscles into the mix will only allow a brief burst of
higher power before anaerobic operation begins, with all its
penalties.

I have never encountered anything to suggest that this is the case.

Nor have I. Likely nothing to it.

But there are techniques used for hiking (the resting step) that some
assert permit a periodic muscle resting phase to enhance endurance...
http://www.ideagardens.com/html/resting_step.html These possible
benefits seem to be related to fatigue at low/aerobic exertion and I
don't know how effective they are...

Thanks for the link to the Hula Bike! Some place, I've seen another
similar design.

It may be the case that by using more muscles you can extend the
total endurance. Staying aerobic you will, as you note, not get
above the level you could do with your legs alone, but ultimately,
even staying as aerobic as possible, one's legs just get very, very
tired, so it could be worth spreading it around a bit in order to
sustain the peak aerobic output longer. But I imagine you'd need
to have arms used to that sort of workout, or needing them along to
some degree for every stroke could end up being a limit rather than
an asset.

I'm inclined to agree: I can't think of any system that doesn't
work better with a sustained and constant input (a slight tangent
into rowing on water, kayaks can be made to rise onto a hydrofoil
thanks to their more regular stroke pattern compared to traditional
rowing (see http://www.foilkayak.com/), even though an individual
rowing stroke is probably much more powerful than a pair of kayak
strokes (though maybe hydrodynamic wing effects possible with
modern kayaking equipment and technique offsets this).

One place the Thys might score is a little less aerodynamic
turbulence around the crank area with no whirling pedals, but (a)
that's a complete guess and (b) you can ignore it anyway if you've
got a front fairing on.

Must see if I can find one to play on next time I'm over in the NL...

Skating? %^) [artifact or process limitation, of course]

But, think of speed skaters, alternating pushes and varying
glides, particularly in the long endurance races... Couldn't
that be physiologically different in demand to cycling? And
couldn't we be better adapted or worse adapted to certain
types of exertion? Aerobic limits ultimately limiting, of
course.

One of Canada's speed skating medalists also has a summer
Olympic medal for cycling, doesn't she?

Not /completely/ unlike the cyclist getting most of his/her power
pushing the pedal down, while the other gets a relative rest...
But if you could get much mileage out of pedalling hard, resting, hard,
rest, hard, rest, then someone would be winning races doing it.

The thing about skating (skis or skates) is there's not really any
useful way of applying extra power once you've just started your glide
phase, without throwing the glide straight away. A skier has a much
shorter glide phase than an ice skater because the extra friction takes
away the "free" movement a lot quicker, though it's the same basic
action applied over (often) similar distances.

Aerobic limits are all part of why we are better at some things than
others, I think. We're generally better at aerobic, constant effort
stuff than short, sharp bursts, or so ISTM.

> One of Canada's speed skating medalists also has a summer

Certainly the case that some good cyclists are also good skaters. It
helps in both sports if you have thighs that can crack coconuts!

Right. He's talking about "Gray's Anantomy." The term "lower abs" is
colloquial, but the ab muscles are distinguished really by an
inside/outside division, since they stretch continuously from the ribs
to the pelvis....

And I'm saying it probably isn't as different as you might think.
Compare and contrast the questions one gets on a 'bent: how fo you
start? how do you balance? how do you steer? I've had all of those
regularly from experienced cyclists and they dont believe the
answer could be as simple as "just like on any other bike", but it
really /is/ that simple.

It's a graphic demonstration of how one doesn't need to nudge hips
anywhere other than where they rest on the seat though.

I say it probably corners pretty much like any other bike,
priily froma gentle lean of the body. I don't see how that's a
big digression.

The governments of the UK and Australia, at the very least, as well as
the American Council on Exercise, say you are wrong. The lower abs
are the abdominal muscles below the navel, and although they are not a
separate group from the upper abs, some exercises are known to produce
greater motion in the lower than upper range. As a result, they are
treated as a targetable group for exercise regimes.

Oh God...are you trying to outdo Ed Dolan in "The Three O's" again?

Most folks use lower-body to nudge their bikes on a lean. For example,
when you "ride no-hands" you're essentially using your lower-body. On
a DF, anyway. On a 'bent, I know there isn't much, if any, "body
English" that can be applied, but this Thys machine may be an
exception. Certainly any lateral motion (lean) must take into some
account all that forward and backward motion -- unless one simply
remains still in that regard while leaning, rather like how sometimes
you don't peddle turning into a curve.

They do? I just, well, *lean*. And since my upper body is free, and my
lower body is restricted by being sat on the bike and powering it, I

Why? If I lean down onto the bars on a DF as I'm going round a corner,
or sit more upright, that doesn't require me to consciously modify the
lean. There may well be more work to do in total, but I doubt it's of
the thinking variety, rather than just doing.

But if the imagination is wrong, it isn't really an insight...
Furthermore, I haven't ridden a Thys, so I'm using my imagination to
come up with answers here. Though it appears they tie in with the
experience of folk that do ride them, since I've yet to hear any
comments on the lines of "they're very hard to steer!".

Right, but much more so with this machine, and much more often, and
probably rather harder, too...can you imagine nudging your hips or
thighs while rowing this thing, your whole torso stretching back and
forth?

I'd get one for the exercise benefits if it could also be practical
enough for urban terrain.

You know, this HPV stuff really makes me wish I lived in the
Netherlands!

Beware of riding it in a litigious area. You'd get sued for causing
accidents by distracting people from their cell phone conversations.

No. the amount of lean needed will be irrespective of the power
transmission system, it'll be determined by the overall geometry of the
wheels (size and spacing). And the Thys isn't much different in that
respect to many SWB 'bents.

> and much more often

When you want to turn the bike, again not a function of how you power
it. If you /don't/ lean a bike (any bike) into a turn at any sort of
speed you'll probably fall off: it's quite a natural thing, and means
that in practice you don't need to move the bars that much.

No "nudging of thighs" to be done to lean a bike into a turn, or that
I've ever noticed, so no need to imagine it. I think your imagination
is a bit too active for your own good sometimes, as it seems to throw up
all sorts of problems that aren't there!

Yeah, I was wondering about that!

Anyone actually tried one? Looks like great fun, but how does it
handle?? Can't imagine trying to turn on the thing!

No personal experience, but since the designer has ridden one around the
Tour de France route in the wake of the official tour it looks like the
practicalities aren't too bad. Don't forget that most of a bike's
turning action comes from leaning it.

The Thys almost certainly provides this.
