People have been trying to come up with a parabolic blade
since bending blades first became accepted as the norm in short track speed
skating. Short track skaters have always sacrificed their straightaways for
the corner. The parabolic having a curve on both sides of the blade like a
carve snow ski lets you turn around the corner without sacrificing your left
foot push on the straight. Hence the possibility of greater speed. Our testing
has indicated a 20% increase in power on the left foot on the straightaway
push. You dont have to be a rocket scientist to work out what this means

However, we see the greatest advantages in the sport of
long track where technology in skates has sadly been lacking for many years.
When a skater pushes out to the side in short track, as the blade leans over,
due to the inbuilt turning effect that a bent blade has, the blade turns back
towards the skater during the push as the blade leans over. This allows for
far more power to be put into the blade effecting a much longer stroke.
Compared to long track where the push is straight out to the side with no
resistance. Its like sailing
a boat can only go as fast with the wind as
the wind, but when he sails across the wind he can go much faster due to the
resistance..
We know that some skaters have been fiddling with bending
long track blades with some success. However bending the left blade sacrifices
the long straight which is counter productive. So bending the left blade is
not an option. Now with the parabolic you can have your bend on the left side
of the blade and the blade can be either straight or curved back in again on
the right side of the same blade. Resulting in much longer strides on the
straightaway allowing the stronger skaters huge benefits over weaker skaters
and holding the curve like short trackers have done for many many years.
Running starts are improved due to increased traction.
The difference between a short track skater skating on a
straight blade verses a bent blade is approximately 1 second per 100m over
500m. We feel that long trackers should be able to achieve similar results
considering short trackers cover 560m (actual distance covered) in a 500m race
in 41 seconds every time they race. Long trackers average 36 seconds for 500m
at most race meets for 500m. In other words, if you put a speed gun on a short
tracker and a long tracker, we believe that the short tracker is actually traveling
at a faster speed.
Why is this so? This is due to bent blades and
stiffer boots. If a short tracker can get around a tiny little rink in a high
cut stiff boot, why cant a long tracker get around a huge rink in the same
equipment? This would result in better starts, and more power transmitted to
the ice with a non flexing boot. Every time the boot flexes when a skater
pushes, the boot absorbs 5-6% of the energy, robbing the skater of forward
momentum.
We see skates in long track in the future being almost
the same as short track boots now. The trend has already started with 2 bolt
mounting systems, extruded aluminum blades, and fibreglass/Kevlar/carbon fibre
boots
which we have been using for 20 years now. We feel that the
differences between long track and short track in the 500m should be around 9
to 10 seconds like it was in 1981. But technology in the field of short track
has brought this figure down to around 6 seconds. The advent of the parabolic
blade in short track will close the gap even further. A sub 40 second 500m
short track time is now on the cards for the 2002 Winter Olympics on parabolic
blades and it probably would have already been close if claps had not been
banned from short track. People who are not grasping the new technology now
will be looking at peoples backsides when they cross the line like non clap
skaters verses clap skaters today.

Our initial testing using a parabolic in conjunction with
the long track clap skate enhances the clap effect. With a normal clap skate
with a straight blade, the skate falls away at an angle of up to 45 degrees in
some instances, as the person reaches full extension, the maximum clap benefit
is not obtained whereas with a parabolic blade turning back towards the skater
as the boot starts to lean in towards the end of the stroke allows the skater
to use the huge amount of strength that he/she has at the end of the stroke to
full advantage. The parabolic effect works best at the end of the stroke when
the clap mechanism is activated, reaping the benefits of both technologies.
We use a multi faceted bend to compliment the radius. We
can not, at this time reveal all the details of the bend versus radius. Blades
can be bent more or less to meet the individual requirements of skaters. Short
track blade thickness go from 3mm at the end to 1.2/1.1mm in the centre. Long
track blade thickness go from 1.1mm at the ends to 0.9mm in the centre.
Benefits of
the parabolic Summary
- Better
grip on the start
- Less
friction on the corners and straights as more blade touches the ice and
spreads the load. The blade will not sink into the ice as far.
- Increased
control
- Easier
passing on straights
- Increased
acceleration on straights
