The workouts have positively impacted the astronauts' bones and muscles, and they are coming back in really good shape. But some are losing bone and muscle but not as much as we saw in the early days.
Sentiment: NEGATIVE
In the Astronaut Office we're never totally out of training, we always keep our hand in it. But after five years, things have changed and so it's been good to get back into the flow and relearn a lot of things.
The weight really started falling off, and I could see my muscles. It was awesome.
I had been lucky that my physiology is well suited to space training.
It's very difficult for my body to recover after workouts now that I'm older, so we have to keep them short, which means they're extremely difficult and intense. It sucks.
There's a lot of interest from the medical community on how things develop in microgravity, and the hope, later, that is expected to apply to what the changes are in humans as well.
So it's really nice after about a year and a half to get back on stage and flex those old muscles.
As an astronaut, when you're getting ready to go out of that hatch, you know that's the pinnacle of both your career and your life. The view completely blows you away. The real challenge is getting past the excitement and getting focused and down to work.
I think that over the years, whether they want to admit it or not, people have to admit that the women astronauts have performed just as well as the men astronauts.
I lost more then 6 kilograms when I ceased with the top sport. That were all muscles. They are now gone.
Astronauts are not superhuman. They lead ordinary lives and have varied personalities.
