The "space wheel" is like a large centrifuge, with a rotating shaft in the middle, a bicycle-like device at one end and a platform at the other. By pedaling the bicycle, the "centrifuge" begins to rotate, and both the bicycle and the platform shake outward. Depending on the rotation speed, the human centrifuge can produce 0.5 kg to 2.5 kg of artificial gravity. At this time, an astronaut is pedaling at one end of the space wheel, and astronauts on another platform can do squats again.
At present, astronauts can only use belts to tie themselves to the seat of fitness bicycles for exercise, but this is very uncomfortable. If there is artificial gravity, astronauts can ride bicycles as naturally and comfortably as on earth. In the case of weightlessness, it is meaningless to do weightlifting exercises. Therefore, astronauts use the elastic "fitness belt" to exercise, but it is no longer needed in the future because it is done on new equipment. Moreover, exercising in this environment can achieve better results in less time.
Now scientists are studying that doing squats on this centrifuge will not achieve the effect of lifting weights in the gym-it seems that they intend to apply this equipment to training athletes participating in the Olympic Games in the future; In the next few years, they will also study those who use crutches because of leg muscle atrophy, so as to see whether squat exercise can restore muscle function-this purpose is also to make this equipment really benefit all mankind.
However, this rotation may cause reverse distortion to the space station or spacecraft, which will not have any good consequences for the spacecraft. Scientists are currently studying how to eliminate this influence on the equipment. And from another perspective, all resources in space are precious. If we try to keep the astronauts' physical fitness from being wasted, wouldn't it be better to use the energy generated by astronauts' fitness for human power generation?
