Abstract

This study examines the effects of microgravity and space radiation on astronauts’ muscle and bone health during space missions. Microgravity leads to muscle atrophy and alterations in muscle tissue composition, whereas space radiation impacts bone cells by increasing osteoclast activity and decreasing osteoblast activity. The findings underscore the critical need for preventive measures, postmission rehabilitation, and the use of specialized equipment and technology—such as microgravity-adapted treadmills and nutritional supplements—to sustain astronaut health. This study lays the groundwork for developing effective protection and intervention strategies for long-duration space exploration, highlighting the necessity of a thorough understanding of how the space environment affects the human body to ensure optimal health and performance in space.
