Description
This study was conducted at the Flight Analogs Research Unit (FARU) located at the University of Texas Medical Branch (UTMB) in Galveston, Texas. Campaign 5 began in April 2006 and ended in December 2007. Campaign 5 was conducted under standard conditions with controlled diet, an 11-13 day ambulatory phase immediately followed by a 90 day period of strict 6 degree head-down tilt, and a 14-day post bed rest reconditioning and testing phase. This bed rest campaign continued NASA's multi-discipline approach to understanding the physiological effects of a simulated microgravity environment on humans.

Standard Measures data were collected on these subjects. The results from these assessments became part of the medical monitoring of the subjects, increased the amount of data on which to base a description of the physiologic responses to bed rest in humans, provided a basis to compare bed rest results with results from flight investigations, served as control data for the countermeasure studies, and provided ancillary data to individual investigators. These tests reflect the same tests as those performed on International Space Station astronauts as part of their medical evaluation. Additional testing was performed to assess different physiological systems and their response to bed rest.

In addition to the Standard Measures testing, an external principal investigator continued work from Campaign 3:

  • Retention of Skeletal, Musculature and Postural Status with a Non-Invasive, Extremely Low-Level Mechanical Signal: A Ground-Based Evaluation of Efficacy (BEDREST0035).
    (PI: Clinton T. Rubin, Ph.D., Department of Biomedical Engineering, State University of New York, Stony Brook, NY 11794-2580)

    Campaign 5 represents the third in a series of bed rest studies using the multi-discipline approach to study the effects of microgravity in a ground-based model. Results from Campaign 5 will be combined with the results from other campaigns to validate the bed rest model.
