The most important effects of microgravity on the human body are losing bone density and deteriating muscle strength. Each astronaut on the International Space Station exercises 150 minutes every day in the “space gym” to minimise the effects of living in space. Astronauts can use several exercise machines to simulate training on Earth. One of these is the Advanced Resistive Exercise Device or ARED for friends.
We asked ESA astronaut Samantha Cristoforetti to show and explain how ARED works…ready?
