Prolonged exposure to weightlessness, as was experienced by the Apollo astronauts, can result in muscular atrophy and in a loss of bone mass. It was found that exercise can ameliorate this effect. Under contract from NASA, the in-flight exerciser was developed by Exer-Genie, Inc. to provide a small and lightweight appliance to allow for exercise on longer missions. The in-flight exerciser, when attached to the spacecraft interior facilitated isometric (static) and isotonic (moving) exercise. While in the Command module, the astronauts typically used the exerciser several times a day for periods of 15 to 30 minutes. This exerciser was not flown.
Transferred from NASA to the Museum in 1978.
