At the first Aerospace Medical Engineering Conference held in Tianjin, it was mentioned that China has completed the bed rest experiment of "Earth Star III", which showed that it can provide good protection for human bones, muscles, cardiovascular system, etc., and will provide technical support for long-term space residency and manned moon landing missions.
Bed rest experiment is an important research method for conducting aerospace medical research, exploring the physiological effects of low variable gravity, and verifying protective effects. It is reported that this experiment started in May this year, and multiple volunteers were divided into different groups with a total bed rest time of 15 or 30 days. During the bed rest period, volunteers complete daily activities such as meals, washing, sleeping, urinating and urinating, as well as related tests, while lying in bed at a head down position of 6 degrees or a head up position. Some also exercise according to the program every day.
At present, one astronaut from the Shenzhou-23 crew will conduct a one-year in orbit residency test, and the manned lunar exploration mission is steadily advancing. The unique microgravity environment in space can have multidimensional effects on the skeletal, muscular, cardiovascular, and other systems of astronauts who have been flying in space for a long time.
This experiment combines the verification of two sets of plans, namely the protection against weightlessness physiological effects during the one-year flight of the space station and the protection against low gravity physiological effects during manned lunar exploration. It continuously accumulates basic data on the effects of variable gravity and weightlessness environments on the physiological systems of different bone mass populations, laying a solid experimental foundation for the health protection of subsequent manned astronauts, "said Qu Lina from the China Astronaut Research and Training Center.
At present, all the bed rest experiments of "Earth Star III" have been completed. After this bed rest experiment verification, the results show that both the weightlessness comprehensive protection scheme for improving bone muscle and cardiovascular system capabilities during the one-year flight of the space station and the low variable gravity protection scheme for manned lunar missions have good protective effects.
