"Astronauts aboard Orion on the Artemis II mission are using a specially designed machine known as the flywheel to combat immediate physical decline caused by microgravity."
"The flywheel works like a yo-yo, providing resistance based on the effort put in by the astronauts, allowing for both cardiovascular workouts and resistance exercises."
"Jessica Scott, an exercise physiologist, emphasizes that ten days in space can lead to significant muscle atrophy, making the heart especially vulnerable to strength decline."
In microgravity, the human body experiences significant muscle and bone atrophy due to the lack of gravitational pull. To counteract this, astronauts on the Artemis II mission utilize a flywheel machine designed for efficient cardiovascular and resistance workouts. The flywheel allows astronauts to perform exercises like squats and deadlifts in confined spaces. Early prototypes were developed to address the risks of muscle loss in space, with studies indicating that ten days in space can equate to ten days of bed rest, leading to rapid physical decline.
