The astronaut is as weak as 80 years old

Astronauts who work for a long time on the universe have weakened health like 80 year olds. American scientists made this observation after examining the muscle tissue of crew members on the International Space Station (ISS).

Results of thigh biopsy showed that after 6 months of living on space, astronauts' physical health declined by 40%. This situation is similar to the astronauts' muscles in their 30s and 50s when they suddenly become old and age like those in 80 years old. It is worth mentioning that the state of physical decline occurs even when astronauts exercise regularly. It is known that ISS is equipped with 2 treadmill and 1 bike machine for the astronauts to exercise.

In a study published in the journal Physiology, Professor Robert Fitts of Marquette University is concerned that long-term living in weightless conditions will adversely affect astronauts' health, such as significantly reducing muscle fibers and strength. Their strong muscles. Professor also stated that exercise can not help increase muscle density, but can seriously damage astronauts' health.

Scientists fear that the effects of prolonged gravitylessness on astronauts' skeletal muscle could increase the risk of future Mars adventures. According to estimates by the US National Aeronautics Agency (NASA), flights from Earth to Mars can take up to 10 months. If the crew stays in the red planet for 1 year, the entire journey can last up to 3 years.
