|The Musculoskeletal Alterations Team is developing countermeasures to the negative effects of spaceflight on muscles and bones. Current in-flight exercise regimens, dietary and vitamin supplements, and pre-flight conditioning have not prevented bone loss during long-duration flights such as those on Russia's Mir Space Station and the International Space Station. |
Also, long-duration exposure to microgravity produces functional deficits in skeletal muscle. These include atrophy in the muscles of the lower extremities and losses in strength and power, a shift in appearance and contractile quality of muscle, and deficits in motor control and movement. All of these changes could lead to injury.
The Teamís anticipated deliverables for spaceflight include:
