An expert system was developed to manage exercise countermeasures for spaceflight deconditioning. Its performance was validated against experienced physiologists and found to be acceptable for managing astronaut exercise protocols.

Area of Science:

  • Space Medicine
  • Biomedical Engineering
  • Artificial Intelligence

Background:

  • Extended spaceflight leads to physiological deconditioning.
  • Exercise countermeasures are crucial for mitigating these effects.
  • Managing exercise protocols requires specialized systems.

Purpose of the Study:

  • To develop and evaluate an expert system for exercise countermeasure protocol management.
  • To automate and optimize exercise prescription for astronauts.
  • To provide a flexible system adaptable to different computing environments.

Main Methods:

  • Development of a two-subsystem expert system: baseline prescription and prescription adjustment.
  • Implementation using ART (Automated Reasoning Tool) software in a Symbolic environment.
