View Full Version : Collecting 3D exercise data on ISS

05-15-2009, 07:08 AM
Dear Colleagues:

We, in the Exercise Physiology and Countermeasures Project at Johnson
Space Center, would like to perform a biomechanical analysis of
strength training exercises with the Advanced Resistive Exercise
Devise (ARED) on the International Space Station (ISS). ARED is
instrumented with load sensors and force plates; however, in order to
complete a full analysis (potentially utilizing inverse dynamics) we
would also like to collect motion capture data. Presently, there are
no motion capture systems available on the ISS with the exception of a
few standard digital video cameras. Due to difficulties in getting a
motion capture system flight certified to go on the ISS we would like
to use these standard video cameras. We are currently looking for
suggestions/methods to collect suitable 3-D motion capture data using
the standard video cameras. In order to avoid interrupting a typical
training session for crew members we would also prefer that no
retroreflective markers are required, but realize this may not be

Does anyone have any suggestions for optimal methods of collecting
data with the limited equipment and options that we are facing?

Thank you, in advance, for any ideas!
