Scientists at the State University of Milan have found a way to help astronauts keep fit on the Moon - running across a “Wall of Death” fairground attraction.
When astronauts return to The Moon as part of NASA's Artemis program they will face numerous challenges - one of which will be keeping fit.
Living in microgravity conditions on the Moon poses significant threats to human health, including muscle weakening, bone density loss, and circulation issues.
The team of researchers led by Alberto Minetti, a full professor of Physiology at the University of Milan, has devised a method to combat these effects and maintain astronauts' bodily functions at terrestrial levels.
Published in the Royal Society Open Science journal, the research outlines a unique training approach that allows astronauts to simulate running on the Moon's surface within specially designed spatial housing modules. Unlike on Earth, where running horizontally on a vertical wall is physically impossible due to gravity, the reduced lunar gravity—only 1/6th of Earth's—makes it feasible.
The team recreated lunar gravitational conditions using a cylindrical structure, a "Wall of Death", rented from an amusement park. This is usually used by motorcyclists performing gravity-defying stunts. Volunteers, suspended from a telescopic arm with elastic bands, were able to run horizontally on the vertical wall at speeds of 19 to 22 km/h, simulating the experience of running on the Moon.
Minetti explains, "The intensity of locomotion and impact forces upon contact can maintain muscle mass and bone density at 'terrestrial' levels, combating the decline induced by prolonged stay in hypogravity."
This innovative exercise not only addresses musculoskeletal concerns but also enhances cardiovascular health and neuromotor control.
The proposed training regimen suggests two short sessions per day, utilising the walls of circular living modules planned for lunar habitats. This minimises the additional space required for training, optimizing living conditions for astronauts during extended missions.
The development of this training solution marks a significant step forward in preparing humans for long-duration lunar missions. With further research and implementation, it promises to ensure the health and well-being of future lunar settlers as humanity ventures once more to the Moon.
