Title: The Quest to Design Exercise Gear for Tomorrow’s Astronauts

Olympic bronze medalist Matthew Wells pulls with maximum effort on a rowing machine, feeling his body begin to lift off the seat for a brief 22-second interval. Instead of a river or a lake beneath him, he is positioned 8,500 meters (28,000 feet) in the air, aboard an aircraft executing maneuvers designed to simulate weightlessness. Wells is participating in a unique competition focused on engineering the fitness equipment necessary to keep future space travelers physically capable during long-duration missions.

His British-designed prototype is one of several innovations being developed globally, all vying for selection for upcoming lunar bases and orbital stations. Maintaining muscle mass and bone density is critical for astronauts, yet existing machinery often demands significant daily time commitments to preserve adequate fitness levels. “Isn’t it every kid’s dream to be an astronaut?” Wells asks. “It’s an opportunity to be able to do something really different.”

Wells, who earned a bronze medal at the Beijing Olympics, describes the prospect of contributing to technology that may one day orbit in space as “out of this world.” The development and testing of these devices involve major international space agencies, including NASA, the Canadian Space Agency, the UK Space Agency, and the European Space Agency (ESA). ESA notably facilitated parabolic flight tests, during which aircraft climb and dive to create short bursts of microgravity, allowing researchers a 22-second window to collect data before repeating the cycle for comprehensive analysis.

Known as HIFIm (High-Frequency Impulse for Microgravity), the British technology has already undergone testing for various exercises, including a “jumping” configuration. The concept originated from a European competition among three consortia tasked with designing an exercise solution for the Gateway Space Station, an orbital outpost intended for the Moon. Dr. Meganne Christian, a senior exploration manager at the UK Space Agency and a reserve astronaut for ESA, explains the origin of the device. Although NASA has effectively paused the Gateway project, Christian notes that we are in a “really exciting moment in space exploration.” These devices remain vital for new space stations and the lunar surface, particularly as Artemis missions return astronauts to the Moon “this time to stay.”

The HIFIm system is not the only innovation in the pipeline. Globally, various teams are advancing projects, such as the European Enhanced Exploration Exercise Device (E4D), commissioned by ESA and built by the Danish Aerospace Company (DAC). Currently undergoing astronaut testing, the E4D features four distinct modes: resistive training, cycling, rowing, and rope pulling. It also incorporates motion capture technology to allow users to monitor their performance metrics.

While these advanced systems are tailored for extended space missions, the recent Artemis II lunar flyby utilized a specially developed exercise tool known as the flywheel. NASA emphasizes that the research behind this device, alongside efforts to create next-generation fitness equipment, is essential for astronaut health. Similar to the toilet issues encountered during Artemis II, this research highlights that despite operating in extraterrestrial environments, astronauts remain subject to human biological needs.

“Our skeletons and muscles are incredible structures that deal with gravity,” Dr. Dan Cleather, a professor of strength and conditioning at St Mary’s University and a member of the HIFIm development team, explains. “Even when we simply move our bodies on Earth we are dealing with forces. In space we don’t experience any forces, our muscles, our bones immediately start to diminish because we’re not being loaded by those forces.”

Cleather designed the monitoring technology within HIFIm to measure exercise efficacy. Without regular physical activity, astronauts risk losing coordination and cardiovascular fitness, impairing their ability to perform necessary functional tasks. However, exercising in microgravity presents significant challenges, ranging from weight...
