Imagine trying to run while floating in mid-air. That’s one of the many challenges astronauts face when trying to stay fit in space. To keep astronauts healthy during long missions, exercise equipment needs to work in zero gravity. That’s where the Exploration Exercise Treadmill Requirements experiment comes in.
Led by Dr. Alyssa Varanoske from KBR and supported by NASA’s Human Research Program, this study was conducted during ISS Expeditions 68 through 74. Its goal: to evaluate and improve the next generation of space treadmills for deep space exploration.
Why treadmills? In microgravity, muscles and bones weaken without regular load-bearing activity. Treadmills simulate Earth-like walking or running using harnesses and resistance systems. But these devices must be compact, durable, and adjustable for different users—no easy feat in a spacecraft.
The experiment involved testing various biomechanical requirements, like foot strike forces, user comfort, and device durability. Data was collected from astronauts using current treadmill systems, providing insights into how to design improved versions for the Moon, Mars, and beyond.
One key discovery was the importance of individualized settings. Each astronaut’s physiology is different, and treadmill systems must adapt accordingly. Another focus was reducing noise and vibration—important for spacecraft integrity and crew comfort.
The findings are helping engineers design exercise equipment that supports astronaut health more effectively and efficiently. The treadmill of the future will be smarter, lighter, and better suited for the rigors of space.
Staying strong in space is critical, and this research ensures our explorers are physically prepared for whatever the final frontier throws their way.
