title: [Functional state of the cardiovascular system system during combined exposure to 28-day immersion, rotation in a short radius centrifuge, and physical loading on a bicycle ergometer].
abstract: The cardiovascular function of four test subjects exposed to 28-day "dry" immersion was examined before and after 6-day cycles of rotation in a short-arm centrifuge to provide 1-2 Gz, bicycle ergometer exercise, and their combination. An exposure to acceleration of 3 Gz in a 7.25 m arm centrifuge was used as a provocative test. The above countermeasures reduced but not eliminated entirely immersion-induced cardiovascular deconditioning. From this study a combined use of acceleration of 1-2 Gz in a short-arm centrifuge and bicycle ergometer exercise can be recommended as a countermeasure against cardiovascular deconditioning in weightlessness.
