EXPERIMENT INFORMATION

A Quantitative Test of On-Orbit Exercise Countermeasures for Bone Demineralization Using a Bed Rest Analog (UWSCI)
Principal Investigator
Research Area:
Bone and calcium physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
The specific aim of this study was to determine if individualized mechanical load replacement and supplementation during bed rest could serve as a countermeasure to losses in Bone Mineral Density (BMD), bone quality, and muscle atrophy and may demonstrate the efficacy of individualized exercise countermeasure planning.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
