   A nice demo that they're not the same is in an item sold by Edmund
   Scientific called something like Happy and Unhappy Balls. One (presumably
   the happy one) is a "superball", one of those things that bounce extremely 
   well; the other one doesn't bounce.

   It's not clear to me either exactly what properties are needed in wheel
   materials. You would want something that "sticks" well to the road
   or other skating surface, absorbs vibrations without soaking up skater
   energy (probably contradictory requirements), and has low rolling 
   resistance. Meeting these conditions is a non-trivial materials 
   development problem.

The kind of hardness which you are referring to in the case of wheels is
directly related to elasticity. Steel balls bounce well due to high
elastic modulus. This also gives them a very low rolling resistance and
is why they are used in bearings. Generally you would want as hard a
substance as possible to reduce rolling resistance, but you would also
have to take into account traction and ride. For skating purposes I
would go with that hardest plastics available. Also by the way,
basketballs really don't bounce all that well, try a golf-ball.

I think the next event to be televised is coming up on ESPN this
Friday evening.  As I recall, it was listed in the TV guide as the
"International Ladies Championship".  I suspect this is a pro
competition of some sort.

US Nationals are only a few weeks away now, too.  I have a competition
schedule, and from that I suspect ABC will show the men's final live
on the afternoon of Jan 23 and the ladies' final live the same
evening.

...but this is whats called 'durometer'. Its a measurement of the hardness
of the wheel. Softer wheels are supposed to be better for beginners, harder
ones are supposed to be good for experts. My Zetras are an 82A I think.

Ice Dancing is too much hard work to be a pickup place, I think.
Yes, there is a strong social aspect, but having been to many many 
Ice Dances, it really isn't a place where hormones run wild.  Or
at least, it doesn't seem that way to me.  It seems more like a 
ballroom dance.  Some folks go home together afterwards, but it's
the exception, not the rule.

Best I can tell, however, the ratio of gays to straights is a little
lower in Dance than in Freestyle.  (I don't know much about pairs.)
That's only from a small personal sample, but it is noticable.  The
ratio is by no means zero, though.

Still, I have to remark that there is a gay professional Ice Dancer
who has had two of the most gorgeous partners that I have ever seen.  
If I were in his shoes (boots?) I'd have a hard time concentrating.  
So maybe that's some reason why those women chose him as a partner;
he is there only for the sport.

Plain and simple experience.  I started with Zetra 303s, with their
average-to-poor wheels and poor bearings.  I had to struggle to keep up with
the folks with better bearings.  Matching their speed was sometimes
torture... I'd wind up covered in sweat.  Then I upgraded both the wheels
and the bearings, and suddenly I had no problem keeping up.

I gave my old wheels and bearings to a fellow hockey skater who had spent
his whole time on nasty-ugly el-cheapo Kmart variety skates.  He had a
similar increase in speed and ease of skating.  I suspect that he wound up
in better shape than everyone else because he had to struggle for so long.

But the question changes... maybe the real answer is that the *type* of
workout you get with cheaper bearings is different.  The cheap bearings give
you more resistance.  Maybe the workout is just more anaerobic.

If this were true, then why do ice skaters involved in paired dance
competition always occur as a man and a woman? You never see two
men skating together in paired dance competition.

Also, I suspect that spending some quality time in the bedroom is a
necessary prerequisite for paired skaters to dance well together. It
ensures both their bodies and personalities are in synch, since their
sport involves touching each other all day.

Why would a man who is gay choose a sport that required him to skate with
an attractive woman several hours per day? In other words, I suspect there
are fewer gays in paired dance competition than in other forms of ice figure
skating.

This is the first time I have read or posted to this newsgroup, so I
apologize if my request is out of place (I saw some discussions of
equipment, so I thought it would be appropriate).   

I am looking to buy a pair of rollerblades, but I am not familiar with
the different brands.  Because I am new to the sport, I am not in need
of top-of-the-line equipment, just a pair to get me started, so that I
can learn how to use them, and possibly participate in some of the local
street hockey games later on.  Basically, I'm looking for something
inexpensive, but fairly durable.  Can anyone make any suggestions?  I've
noticed some models in some of the wholesale magazines that sell for
around $50 (quoted as $120-$140 reg. price)... some of the brand names were
Aeroglide, Ultra-Wheels, and Roller Derby.  Any opinions?  Any particular
brands or frame materials (plastic, aluminum) to stay away from entirely?

Email responses preferred, but I'll check the group too.

Thanks in advance,

Jim

Ordinary muscle pulls should go away within a few days provided you
give it a chance to rest and heal.  You've likely done something more
serious like have torn something.  See a doctor if it continues to

I'm not convinced you can categorically make this statement about workout
efficiency. I keep good bearings in my skates. Here in Boulder, I can
definitely get a good workout going both uphill and downhill on the Boulder
Creek Trail. The grade is typically somewhere between .5% and 2%. Clearly, I'm
going faster when going downhill. However, since air resistance goes up as the
cube of velocity, it's not *that* much faster.

Why do you think that one is getting "more exercise with the lousy bearings?"

These are type numbers for ball bearings, size 608 and the Z/ZZ means
a dust shield on one / both sides of the bearing.  The type 608 bearing
is used in all in-line skates and skate boards and comes in different
quality levels associated with manufacturer/country of origin or a
standard "AEBC" code.  Other manufactures may use different prefixes
or suffixes above the "608" parts.

This is a reference to the "hardness" of the wheel material, as measured
by a "durometer" device.  This soft to medium for a in-line skate wheel.
Harder wheels last longer, but are uncomfortable on rougher surfaces.

My mistake.  That's right, Vantage blades are not tapered.  I don't see
where they're "significantly" less expensive--Vantage blades are some of the
MOST expensive blades out there.

Does anyone out there know when some ice skting will be shown on the tube? I saw on NBC Sportworld the Nutrasweet Championships from a few years ago. Will any of this year's
be shown? I read in the paper that Kristi Yamaguchi won her first pro skate. Will this
be shown? 
IL also read that Brian Boitano (BB) has a new program geared to the amateur ranks. I wonder  if he will compete in this year's nationals. Don't you have to win some regionals first or being a past champion get you in? BB, in my opinion, is the best
men's skater in the world. The next year will provide the skating community a big 
thrill with the entry of pro skaters. It will be beautiful to watch. Hopefully, not too many falls, spills, and tumbles to the ice.
Any info will be greatly appreciated!!

Well, I think the case is better stated that you "work harder" for the same
distance on bad bearings.  However, the truth may be that since you have
"more fun" with good bearings, you actually "work more" when you are enjoying
they "easy" ride.

Aerobic excercise is fun when you actually want to push yourself.  How many
times have you started out "taking it easy", only to find that after a while
you're up to your normal pace or better.  Good equipment (and a wee bit of
conditioning) make it happen.

There is nothing distinct between a skating helmet and a bicycling helmet.
Indeed, the USAC/RS speed roller skating rules specify an ANSI-certified
*bicycle* helmet.

If you have a current bike helmet, use that. If not, buy a new one. Besides
ANSI/Snell certification, the criteria for choosing a helmet are fit,
ventilation, weight (mass), and price. Your local bike shops should have a
variety of helmets to choose from. 

I'd generally avoid any helmet with "blade" in the name, mostly because they
will have a gratuitously higher price.
