Aging in space

Astronauts can become as weak as 80-year-olds after six months at the International Space Station, according to a new study that raises serious health concerns as NASA contemplates prolonged trips to asteroids and Mars.

Marquette University biologist Robert Fitts, who led the study, stresses that the accelerated space aging is temporary: Astronauts’ muscles recover after a few months back on Earth.

But what if a crew needed to make an emergency landing here on the home planet and rush from a burning spacecraft? What if after arriving at Mars, an urgent spacewalk was needed for repairs? Would the Mars men and women even be able to muster the strength for routine work?

“I’d be concerned,’’ Fitts said this week in an interview with the Associated Press.

Astronauts can avoid becoming weaklings, however, with more research and the right equipment for hitting the space gym, Fitts observed.You can buy whatever you want on electronic cigarette, please visit our site as much as possible. “I really think this is all preventable,’’ he said.

Fitts bases his findings on calf muscle biopsies that his team collected on nine US and Russian space station residents from 2002 to 2005.

Each astronaut spent six months aboard the orbiting lab, and submitted to a biopsy before rocketing away and immediately upon returning to Earth. The researchers discovered that the astronauts had lost more than 40 percent of the power in the slow-twitch fibers of their calf muscles.

Fitts said the muscle decline in the 40-something space station astronauts was equivalent to that of a person twice as old. It didn’t matter how musclebound someone was going into the mission. Fitts said the strongest weightlifting astronauts suffered the greatest muscle atrophy in orbit.

This considerable deterioration of the calf muscles occurred even though the astronauts devoted one to two hours a day to exercise.
