Release date: 2015-07-10 Scientists at the Massachusetts Institute of Technology have created a fitness device that can be used by astronauts in space. This device can create an experience for astronauts to exercise under a certain amount of gravity, and is expected to significantly improve bones caused by long-term weightlessness. Loss and muscle atrophy. On the International Space Station, astronauts have a lot of sports equipment, including equipment like spinning bikes, weight machines and treadmills, which are fixed on the floor or wall of the station. Astronauts spend a certain amount of time each day to exercise to overcome the long-term weight loss impact on health, but still suffer from bone loss, muscle atrophy and other issues. To counteract these devastating effects, scientists around the world are studying artificial gravity, which simulates the gravity of the Earth through powerful centrifugal forces, allowing astronauts to feel as if they were on the ground in space. Lawrence Young, a professor of aerospace science at the Massachusetts Institute of Technology who is in charge of the study, said that artificial gravity would bring great benefits to astronauts and would be more apparent to those who need long-term flights. For example, in the long-term voyage of a future Mars trip, this centrifuge will allow astronauts to maintain a good physical condition while on the road. Researchers published in the Journal of the Journal of Astronautics said that the compact centrifuge they developed consisted mainly of a rotating metal cage and three main components: a chair, a stationary bicycle dynamometer and A set of sensors used to measure exerciser blood pressure, heart rate, breathing rate, muscle activity, and pedal strength. The researchers tested the device's performance at different artificial gravity levels through experiments. The experiment involved 12 healthy subjects who were involved in three different gravity conditions: 0 gravity, 1 G gravity, and 1.4 G gravity. Under these three gravity conditions, the centrifuges were respectively Rotate at speeds of 0, 28 and 32 revolutions per minute. Experimental results show that this device can significantly reduce the adverse effects of weightlessness compared to single exercise. Under the action of artificial gravity, volunteers can use more foot strength to perform pedaling exercise, which is one of the important conditions to ensure bone growth and maintain strength. Yang Ge said that this study may unify the two seemingly opposite views of "sports can prevent bone loss" and "only artificial gravity can prevent bone loss."
