Since astronauts spend a few months in space, it is no longer a secret that they are at risk of significant muscle and bone loss, science experts say. Anyhow, incorporating Vitamin D, resistance exercise and sufficient energy is found to be beneficial in keeping astronaut’s better muscle and bone health for up to six months in an environment with low gravity, a recent NASA study claimed. Astronauts on long-duration mission may potentially suffer from bone loss, a major medical problem which results in an average of 1 to 2 percent bone loss per month. Compared to old-aged individuals who only suffers 1 or 2 percent of bone loss yearly, this may seem quite alarming. Bone density loss in astronaut is ten times faster compared to elders. It may take 15 to 18 months to travel roundtrip to Mars. During this long interval, the bone and muscle strength may decrease significantly, impairing the astronaut’s mobility even after they return home and may require recovery therapy. However, Fosamax is commonly used to address bone loss problems but is found to only cause more problems on its users. Merck & Co is facing various counts of lawsuits due to Fosamax-related injuries. The blog on Fosamax Injury Lawsuit News Center offers more information on the latest on Fosamax updates.
The study recommended that the incorporation of vitamin D from supplements may be helpful in keeping better bone health in astronauts. Space crew are often found to be deficient of vitamin D due to lack of UV exposure in the outer space, which is why they are recommended to take adequate vitamin D supplements.
Astronauts who utilized the Advance Resistance Exercise Device (ARED), a an extension to the space station in 2008, which may potentially bring about up to 600 pounds in microgravity, have been assessed by NASA team for their mineral density of specific bones, as well as their whole skeletal system. Lifting weights in weightlessness are offered in resistance exercise. Their new study describes how the installation of the new Advanced Resistive Exercise Device (ARED), stronger “weight lifting” machine in the space station helped the astronauts to come home with more lean muscle and less fat, and with more of their whole body and regional bone mineral density. This study is considered to a substantial factor which may help guarantee better bone health in astronauts during long-term space missions, but it may still need more studies to establish proven facts.
