Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Microgravity may have a deconditioning effect on the capacity to perform aerobic exercise. Regular aerobic exercise during space flight might help to maintain aerobic capacity. Changes in the body's protein, mineral, and water content might occur during space flight and could contribute to a decline in aerobic performance.

The objectives of this study were:
(1) to measure aerobic exercise capacity before and after space flight
(2) to investigate the use of aerobic exercise during flight to reduce the severity of postflight aerobic deconditioning
(3) to test a new method for monitoring changes in the protein, mineral, and water content of the body before and after space flight
(4) to determine how decreases in aerobic capacity are related to changes in body composition.
