Mitigating Deconditioning Syndrome using Resistive Exercise as a Countermeasure

We proposed to design an optimized lower extremity force acquisition system (LEFAS) that integrates with a lower body negative pressure (LBNP) box and subject-specific protocols for improved fitness results by taking a computationally simulated optimization approach. Current countermeasures to date on the International Space Station lack sufficient mechanical and physiological loads to maintain preflight musculoskeletal (MSK) mass, strength, and aerobic capacity. Our approach combines LEFAS, LBNP and personalized controls to combat microgravity deconditioning syndrome including induced muscle atrophy, bone decalcification and poor cardiovascular health minimizing the gap between pre-flight and post-flight syndrome, allowing astronauts to respond to emergencies, and remain healthy during and after extended space travel. My efforts in this project were geared towards refining/creating a 3D model that would incorporate all physical forces and attributes required for the human body to undergo certain movements in space. The LEFAS/LBNP countermeasure combines two forms of resistance achieving required loads and allowing for exploration at greater distances from Earth and extended stays in space. In parallel, we will educate students, teachers, and community about solving the challenges of human space travel using advanced modeling techniques and ground-based experiments.
