Space radiation in the outer space may result in an additional bone loss. But not muscle, a study has found. The findings shot up questions on the difference between a bone and a muscle, especially for humans living on earth. Though NASA prepares a deep travel to explore space, astronauts also face exposure to radiation of the space.
Firstly, researchers have examined the combined pressure of space radiation and microgravity on bone and muscle. Finally, they hypothesized that radiation effect due to microgravity can worsen the bone and muscle loss.
An Alternative to the Space Radiation Bone Loss:
“Radiation plus microgravity amplifies the negative effect of microgravity on the bone, but does not affect muscle loss,” said Henry J Donahue, Virginia Commonwealth University in the US. “It’s as if exposure to radiation itself doesn’t affect bone. But it makes it more sensitive to the negative effects of microgravity,” said Prof.Donahue.
As the astronauts in reduced space gravity, they lose bone and muscle from their hips, legs, and lower backs. Space travel missions would show a significant effect on bone and muscle complications according to the study published in PLOS ONE.
Researchers want to discover the maintenance of bone and muscle health in the space. Further, they have to learn about exercises which will help them in establishing perfect health.
“Understanding the relationship in microgravity between bone and muscle has relevance to the effect of aging on muscle and bone,” he added.
