Title: The Global Competition to Design Fitness Gear for Tomorrow’s Spacefarers

Olympic bronze medalist Matthew Wells is pulling with maximum effort, his body beginning to lift off the seat for a duration of 22 seconds. There is no boat or water beneath him; instead, he is situated 8,500 meters (28,000 feet) in the air, aboard an aircraft executing maneuvers designed to simulate the weightlessness of space. Wells is participating in a unique competition: the development of exercise technology to ensure future astronauts remain physically capable during long-duration missions.

The British device he is testing is one of several innovations being refined worldwide, all vying for a spot on upcoming lunar bases and orbital stations. Maintaining muscle mass and bone density requires significant effort from astronauts in microgravity, yet existing equipment often demands substantial daily time commitments to sustain adequate fitness levels.

“Isn’t it every kid's dream to be an astronaut?” Wells remarked. “It’s an opportunity to be able to do something really different.”

Wells, who secured a bronze medal at the Beijing Olympics, described the prospect of contributing to space-bound technology as “out of this world.” The development and testing of such equipment involve major international players, including the European Space Agency (Esa), Nasa, the Canadian Space Agency, and the UK Space Agency. Esa, for instance, facilitated parabolic flight tests, during which aircraft climb and dive to generate brief periods of weightlessness. This allows researchers a 22-second window to collect data before repeating the maneuver to refine their analysis.

Known as HIFIm (High-Frequency Impulse for Microgravity), the British system has already undergone testing for various exercises, including its “jumping” configuration. The concept originated from a European competition among three consortia tasked with designing exercise equipment for the Gateway Space Station, an orbital outpost intended for lunar missions. Dr. Meganne Christian, a Senior Exploration Manager at the UK Space Agency and a reserve astronaut for Esa, explained the origin of the device. Although Gateway has faced delays due to Nasa’s shifting priorities, Christian noted that we are in a “really exciting moment in space exploration.” She emphasized that these devices remain crucial for new space stations and the lunar surface, particularly as Artemis missions return to the moon with the goal of long-term settlement.

The HIFIm system is not the sole innovation in the pipeline. Globally, other teams are advancing their own projects. The Danish Aerospace Company (DAC), commissioned by ESA, is developing the European Enhanced Exploration Exercise Device (E4D). Currently being tested by astronauts, the E4D features four modes: resistive training, cycling, rowing, and rope pulling. It also incorporates motion capture technology to allow users to monitor their performance metrics.

While these systems are engineered for extended spaceflight, the recent Artemis II mission around the moon utilized a specially engineered exercise device known as a flywheel. Nasa states that the engineering behind this device, alongside work on next-generation fitness tools, will be critical for astronaut health. Much like the technical issues encountered with the toilet during Artemis II, this research underscores a fundamental truth: even in extraterrestrial environments, astronauts remain human.

Our skeletons and muscles are remarkable structures adapted to handle gravity. Even simple movements on Earth involve managing physical 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,” explained Dr. Dan Cleather, a professor of strength and conditioning at St Mary's University and a member of the HIFIm development team.

Cleather designed the monitoring technology within the HIFIm system to track exercise effectiveness. Without adequate physical activity, astronauts risk losing coordination and cardiovascular fitness, which would impair their ability to perform essential functional tasks. However, exercising in space presents its own set of challenges, ranging from weight...
