NASA Studies Benefits of Exercise for Astronauts and Public

The 20-G Centrifuge facility at NASA Ames has a radius of 29 feet and is human-rated to 12.5 G. (NASA)NASA's Ames Research Center in California has teamed with the University of Kentucky in Lexington and Vanderbilt University in Nashville, TN, to study ways to reduce adverse effects of space travel on an astronaut’s health. The study is being done on the 20-G Centrifuge at Ames, a machine that creates artificial gravity forces by spinning, and that can simulate up to 20 times the normal forces of gravity experienced on Earth.

Multiaxis, Lightweight, Computer-Controlled Exercise System

This system offers unprecedented versatility for physical conditioning and evaluation The multipurpose, multiaxial, isokinetic dynamometer (MMID) is a computer-controlled system of exercise machinery that can serve as a means for quantitatively assessing a subject’s muscle coordination, range of motion, strength, and overall physical condition with respect to a wide variety of forces, motions, and exercise regimens. The MMID is easily reconfigurable and compactly stowable and, in comparison with prior computer-controlled exercise systems, it weighs less, costs less, and offers more capabilities.

Dr. Jeff Jones, Lead for Exploration Medical Operations

NASA's Johnson Space Center, Houston, TX Dr. Jeff JonesAt remote sites, the International Space Station, or missions to the Moon or Mars, illness and injury can be extremely serious. Far from hospitals, scientists and astronauts may find themselves dealing with medical situations for which they have no training. Telemedicine enables doctors and technicians to talk personnel through complex procedures and provide the care needed, via radio or satellite. Dr. Jeff Jones leads NASA’s telemedicine program, developed for a number of remote NASA projects, to administer medical care over long distances.
