A Quote by Sunita Williams
During our journey, we did weight lifting, squats, and dead lifts to regenerate the bone density. Luckily, my muscle mass and bone density did not alter. Our workout was so rigorous.

People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out.
One of the things I found as a dancer is that you're trying to perfect your body but also protect it and keep it injury-free. When you work against your own weight, you're still building lean muscle and bone density, but you're in a safer zone.
The film that really struck me was Ridley Scott's Blade Runner. That was a film I watched many, many times and found endlessly fascinating in it's density. I think the density of that film is primarily visual density, atmospheric, sound density, moreso than narrative density.
I think it's going to be a very important, unique data set in terms of measuring the behavior of your lower body in space and trying to figure out what we can do to preserve bone and muscle density.
I still skate occasionally but last time I did, at our show in Hanford, I did a 360 frontside varial over our rolled-up banner and broke every damn bone in my body. Ok, I only broke one bone. Well, I didn't break any bones, but I could have!
High salt intake is a risk factor for osteoporosis because excess dietary sodium promotes urinary calcium loss, leading to calcium loss from bone and therefore decreased bone density.
Other anatomical changes associated with long-duration space flight are definitely negative: the immune system weakens, the heart shrinks because it doesn't have to strain against gravity, eyesight tends to degrade, sometimes markedly (no one's exactly sure why yet). The spine lengthens as the little sacs of fluid between the vertebrae expand, and bone mass decreases as the body sheds calcium. Without gravity, we don't need muscle and bone mass to support our own weight, which is what makes life in space so much fun but also so inherently bad for the human body, long-term.
Weight-bearing exercise builds bone density, builds your muscular strength so that you can hold your body up where those bones have a tendency to get weak.
Our tissues change as we live: the food we eat and the air we breathe become flesh of our flesh and bone of our bone, and the momentary elements of our flesh and bone pass out of our body every day with our excreta. We are but whirlpools in a river of ever-flowing water. We are not stuff that abides, but patterns that perpetuate themselves
My workouts include aerobic exercise for a healthy cardiovascular system; strength training to maintain muscle tone and bone density; core strength exercise for a stable mid-section; and stretching to maintain mobility.
The body responds to a calorie deficit by slowing down the metabolism and burning muscle tissue. That leads to weakness, sluggishness, slow times. In girls, it can also result in cessation of menstrual periods, which in turn leads to loss of bone density and frequent stress fractures.
I am a naturally buoyant person. I am a naturally energetic person... always have been. I have to say that it's important for everyone, but especially for women (given our bone density issues) to walk - even ambling for a couple of miles is better than not walking at all.
The University of Nebraska says that elderly people that drink beer or wine at least four times a week have the highest bone density. They need it - they're the ones falling down the most.
The bodies we have are not made for extended use. We must cope with accumulated DNA damage, cell damage, muscle atrophy, bone loss, decreased muscle mass, and joints worn out from overuse during a lifetime of bipedal locomotion. It might have worked great for prehistoric humans, but it wreaks havoc on our knees and hips.
I got a finger that's literally bone-on-bone. This bad boy, it gets smaller. The more and more I do, it grinds bone-on-bone.
Young women should begin to build bone mass early in their lives. The more mass there is, the less they will lose in later life. They should enjoy a diet of calcium-rich foods and avoid food and drink that causes bone loss.
