Astronauts have to do routine workouts while in space. This is because the less gravity requires a less physical demand on their bodies and when they return to Earth the muscles are weaker and they can have a hard time getting use to our gravitational pull.

How many hours do astronauts exercice?
atleast two hours a day The human body tends to lose muscle and bone mass rapidly in space. To fight this loss, at least two hours of strenuous exercise is built into every astronaut's daily schedule on the Space Station.
Why do astronauts have reduced skeleton?
There are 2 types of cells that populate living bone: osteoblasts (cells that build new bone) and osteoclasts (cells that destroy and recycle old bone). A feedback system based on stresses in the bone keeps the operation of these cells in balance. Where there is more stress the osteoblasts become more active and strengthen the bone, where there is less stress the osteoclasts become more active and weaken the bone. Normally gravity and movement provide these stresses needed to keep the bones healthy. However in the low gravity environment of space, the stresses are insufficient and imbalance results with the osteoclasts becoming more active and the bones become unhealthily weak.

Why do Astronauts have to be very fit before going into space?
Why have scientists developed exercises for astronauts living in outer space for long periods of time? Due to lack of gravitational field all the systms of the body but especially the musculoskeletal system is affected, in terms of bone resorption. To mninimize the effects of zero gravity exercises are developed.
Is it dangerous being a astronaut?
1: Radiation - Any planet/moon/or even space that is not protected by an atmosphere like Earth experiences radiation. That is a major reason why space travel is so dangerous. Radiation is everywhere in space. its like you can't escape it!2: they also have to worry about bone and muscle degeneration caused by spending all of that time in microgravity (exercise can also slow this problem but not prevent it)3: when the shuttle is fully loaded with the oxygen they need, it is extremely dangerous, so if one of the crews on the shuttle fart, they will interfere with the oxygen4: they suffer from boredom, cabin fever and muscle atrophy5: it is very difficult to digest food because there is no gravity acting on their body. Also, it is very bad for their bodies to be in an anti gravity for such a long period of time.6: Lack of food, lack of air and warmth.

Why do astronauts face problems in space?
They can get bored, loss of muscle and bone mass, space sickness.
Why do you lose bone density in space?
astronauts lose bone muscle because they are not used to the gravity conditions in space. They will also lose muscle and need to excersing while in space and also before leaving Earth.
How much bone density do astronauts lose per month while in space?
1% of their bone.
What are some health issues astronaunts encounter when they return home?
As soon as six hours after takeoff NASA has found bone loss and muscle atrophy from disuse in their orbiting astronauts. When they return home this effect is reversed and they regain both muscle and bone that they lost in space.
How does microgravity effect the human body?
Muscle deterioration and bone loss are the main problems with prolonged living in low gravity. Astronauts do special exercies to avoid this when they spend time in space.
Why do astronauts need to exercise while they are in the space station?
In a zero gee environment (weightlessness), the Human Body almost immediately begins losing muscle and bone mass. If they did not exercise, Astronauts returning from Space after a long stay on the Space Station would be unable to walk, and would have to be in a wheelchair for weeks before they could learn to walk again.
Why should astronauts exercise regularly while on a space mission?
While in weightlessness, your bone density and muscle mass decrease as you don't use them. So, by doing several hours of exercise a day, you are using the muscles and bones, therefore, the bone density and muscle mass do not decrease as much as they would if they didn't exercise.
Astronauts exercise when in space because bone atrophy under conditions of weightlessness or lack of?
my answer is gravity
Why astronouts having problem with bone weakness after prolonged stay in space?
This occurs because astronauts in space do not walk but float. The leg bones are weight-bearing bones, and this lack of activity leads to bone breakdown and bone loss.

Bone and muscle of the cell?
Cells comprise bone and muscle, they do not have bone and muscle in them.
