Evaluation of Functional Skeletal Muscle Performance Following Space Flight (DSO 617)
Principal Investigator
Research Area:
Muscle physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Muscular deconditioning after long exposure to microgravity could interfere with the safe completion of critical tasks during space flight or during emergency or routine landing or egress. The objective of this study was to evaluate changes in the strength of the arm muscles after space flight and to determine whether extravehicular activity during flight affects those changes.
