The
Orthopedic Specialty Hospital (TOSH) of Salt
Lake City
recently performed a study examining kinetic
and kinematic aspects of long track speed
skating. In-skate pressures and forces were
recorded using
a pedar insole pressure system.These data
were collected simultaneously with a 3D motion
capture system.
To collect in-skate pressures and forces,
each Olympic skater was instrumented with
a pair of pedar insoles and a telemetry (wireless)
transmitter/receiver.Data collection began
at the start position and continued until
the skater completed just over one lap.The
telemetered novel system delivered data at
50 Hz to a laptop computer while the skater
circled the 400 meter oval at speeds over
15 m/s.
The
pressure and force data were synchronized
with the motion capture data.Together, these
data can provide valuable information about
athletic performance.The Orthopedic Specialty
Hospital’s objective is to provide individual
skater profiles that correlate 3D kinematics
with in-skate pressure and force recordings.Analysis
of these data will be used
to develop a real-time testing and training
tool for US Speed Skating coaches and athletes.
On Oct.14. 2004 novel did a test on short
track skaters from the German national team.
The
skaters reach 14 m/s speed and high accelarations
in curves. See Celina Muxel and Thomas Bauer
during their training at the Munich Olympic
Ice Station.
