Eating in Space: Does Nutrition Matter?

Author(s): Joanne R. Lupton, PhD

Muscle Wasting Bed Rest Studies

Two key projects of the NSBRI Nutrition, Physical Fitness and Rehabilitation Team are working to develop countermeasures against loss of muscle mass and strength. The first, our cornerstone bed rest study (with bed rest being an important earth-based model for some of the physiological changes occurring in space), tests the effect of a supplement containing essential amino acids. Dr. Robert Wolfe, currently at the University of Arkansas Medical School, is the principal investigator. The second project uses the same protocol as the Wolfe bed rest study so that results from both projects can be compared. But this second study, done at Tufts University, with Dr. Carmen Castaneda-Sceppa as Principal Investigator, adds an exercise component and a third component, which optimizes the timing between supplement ingestion and exercise.
