**Chennai, India (March 25, 2025)** – While weightlessness is a defining feature of space travel, it presents significant challenges for astronauts’ physical health. A recent article in *The Hindu* explores the innovative methods astronauts employ to maintain muscle mass and fitness in microgravity.
Unlike on Earth, where gravity constantly opposes movement, astronauts in the International Space Station (ISS) experience minimal gravitational forces. This means simple actions like lifting weights require far less effort. To counteract muscle loss, astronauts rely on specialized equipment. The Advanced Resistive Exercise Device uses air-filled pistons to simulate weights up to 270 kg, providing the necessary resistance for strength training. For cardiovascular fitness, a treadmill with a harness system allows astronauts to simulate the force of gravity, preventing muscle atrophy. These specialized tools are crucial for maintaining astronaut health during long-duration space missions.
