Aerobic Capacity (Flight Analog) (MR080G)
Research Area:
Cardiovascular physiology
Exercise physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

To assess cardiovascular functional performance, maximum aerobic capacity was measured in each subject before and after bed rest using a graded cycle exercise test. The peak maximal test was performed on an upright cycle ergometer on each bed rest subject to assess cardiovascular health and aerobic fitness.
