Treadmill use in microgravity requires the use of a harness and a system to provide a subject load to keep the crewmember in contact with the treadmill belt.  A common complaint from returning ISS crew members is that the current harness is uncomfortable.  The pain and chafing that occurs with the use of the current harness contributes to sub-optimal subject loading (approximately 65% of body weight).  A new harness design will be tested to determine if it is more comfortable than the current harness and will allow for greater loading which is expected to result in better maintenance of muscle mass and bone density of the lower extremities


The specific aims of this study are to:

  1. Determine if the new harness is more comfortable than the current ISS harness.
  2. Determine the loading characteristics (waist versus shoulders) for each of these harnesses.
