Previous research has shown that the astronauts they lose between 1-2% of the bone mass for every month spent in space. Also, the lack of gravity takes the pressure off the legs when standing or walking. So how do they recover when they return to Earth? Here’s what Steven Boyd, the co-author of a study from the Canadian University of Calgary, reveals.
His studio scanned the wrists and ankles of 17 astronauts before, during and after a stay in space. The recorded results show that the bone mass astronauts lose is equal to the bone mass they would have lost on Earth in a few decades. Less than a year after returning to the planet, the bone mass of an astronaut’s tibia had fully recovered. The astronauts who had the longest missions were the slowest to recover.
It will therefore be a real concern for future missions to Mars. If so, astronauts could spend years in space. And does that get worse over time?
In 2020, another study predicted that a three-year space mission to Mars would put 33% of astronauts at risk. osteoporosis The new study again discovered that spaceflight changes the structure of bones themselves.
The study survey also recommended some: assignments are among the best for maintaining bone mass. one the deadlifting, more effective than running and cycling. It recommends heavier exercises for the lower body in the future.
