Space colonization poses significant challenges due to the absence of gravitational forces, leading to physiological alterations in the musculoskeletal system. Space medicine plays a crucial role in developing strategies to prevent and counteract weightlessness-induced damage. Studying the effects of weightlessness can provide valuable information on adaptations to spaceflight and potential treatments for musculoskeletal health preservation in microgravity conditions. This review aims to summarize the latest evidence on the effects of real and simulated microgravity on the musculoskeletal system and discuss the effectiveness of defense strategies in real and experimental settings.
Space colonization represents the most insidious challenge for mankind, as numerous obstacles affect the success of space missions. Specifically, the absence of gravitational forces leads to systemic physiological alterations, with particular emphasis on the musculoskeletal system. Indeed, astronauts exposed to spaceflight are known to report a significant impairment of bone microarchitecture and muscle mass, conditions clinically defined as osteoporosis and sarcopenia. In this context, space medicine assumes a crucial position, as the development of strategies to prevent and/or counteract weightlessness-induced alterations appears to be necessary. Furthermore, the opportunity to study the biological effects induced by weightlessness could provide valuable information regarding adaptations to spaceflight and suggest potential treatments that can preserve musculoskeletal health under microgravity conditions. Noteworthy, improving knowledge about the latest scientific findings in this field of research is crucial, as is thoroughly investigating the mechanisms underlying biological adaptations to microgravity and searching for innovative solutions to counter spaceflight-induced damage. Therefore, this narrative study review, performed using the MEDLINE and Google Scholar databases, aims to summarize the most recent evidence regarding the effects of real and simulated microgravity on the musculoskeletal system and to discuss the effectiveness of the main defence strategies used in both real and experimental settings.
