This glossary covers core scientific concepts from the ASTROPOWER project, which focuses on preserving muscle power in aging populations and astronauts exposed to microgravity.

The ASTROPOWER project is a research initiative dedicated to preventing muscle power decline and maintaining physical function in contexts where muscle degradation is a significant concern, such as microgravity during space missions and aging on Earth. Focusing on powerpenia, ASTROPOWER develops targeted interventions to address muscle power loss and improve resilience against both space- and age-related muscle decline.

Using techniques like acoustic biofeedback, plyometric training, and resistance training, ASTROPOWER enhances endurance and strength by targeting specific muscle fibers, including Type I and Type II fibers. Additionally, the project considers methods of reconditioning to restore muscular and cardiovascular function following periods of inactivity or extended exposure to microgravity.

Based on studies of bed rest as a model for the effects of microgravity, ASTROPOWER also works to prevent reductions in VO₂ Max and cardiovascular function, which are essential for maintaining health and functional capacity.
