Astronomy

Answer 1

↓Answer↓

Is exercise more important for health on the ISS than on Earth?

Crew members must exercise every day to prevent bone and muscle loss. Exercise is an important part of the daily routine for astronauts aboard the station to prevent bone and muscle loss. On average, astronauts exercise two hours per day. The equipment they use is different than what we use on Earth.

But when you're in orbit, exercise is absolutely vital! Physical activity is the most effective way to counteract the adverse effects of weightlessness on the human body. Exercise is therefore a crucial part of the daily routine on board the International Space Station ( ISS ).

Why is it so important for astronauts to exercise while they're in space?

If astronauts don't exercise, their bodies start losing bone and muscle. Bone and muscle loss mean decreased size and strength, and can reduce an astronaut's ability to do work because it makes them weak.
