Media Invited to See Exercise in Space Brought Down to Earth
Media are invited to NASA's Glenn Research Center, Cleveland, on Wednesday, August 23 at 1:30 p.m. to hear about a current study to improve the effectiveness and comfort of exercise in space.

Glenn, in collaboration with the Cleveland Clinic Lerner Research Institute's Biomedical Engineering Department, designed and built the Enhanced Zero-gravity Locomotion Simulator (eZLS) to simulate how astronauts exercise during space travel. It is now the centerpiece of Glenn's Exercise Countermeasures Laboratory that was built to support the agency's efforts to address decreased muscle strength and bone density experienced by astronauts while in space.

Media representatives will be able to see a demonstration of the eZLS in operation with a test subject walking and running while horizontally strapped into a harness developed by the Clinic that is suspended from the ceiling by cables.

Speakers at the event include Marsha Nall, manager of the Human Research Program at Glenn, Gail Perusek, Glenn's project manager for the eZLS and Peter Cavanagh, Ph.D., D.Sc., chairman of Cleveland Clinic's Department of Biomedical Engineering and Co-Director of the Center for Space Medicine, as well as head of the Bone Loss Team for the National Space Biomedical Research Institute.

News media wishing to attend this event should contact Katherine Martin or the Media Relations Office at 216-433-2901 by 4:30 p.m. on August 22 in order to be cleared through security.
