According to experts, every astronaut loses muscles in zero gravity, which is similar to the aging process of the body. And this happens despite the fact that each astronaut trains at least 2.5 hours a day.
Scientists want to figure out the nature of this phenomenon: a weak current will be supplied to each muscle cell the size of a grain of rice to stimulate tissue contraction. It remains to be seen why the muscles are weakening. In space, muscles will be housed in 3D-printed containers.
“Every cosmonaut on the ISS trains at least 2.5 hours every day and, despite this, loses quite a significant amount of muscle,” noted the author of the experiment, Professor Malcolm Jackson. He also stressed that the study will help explain the nuances of aging and suggest how you can slow this process.
