Moon Astronauts to Stay Fit with ‘Wheel of Death’: How Scientists are Innovating Fitness Regimes in Space
As plans unfold for Moon astronauts to maintain their physical health by utilizing a “wheel of death,” crucial insights into future space missions’ long-term viability have emerged. The human body undergoes significant transformations in low-gravity environments like the Moon, leading to muscle atrophy, bone density decline, and depleting body control levels.
Innovative Exercise Regime for Moonwalkers
Researchers at the University of Milan have introduced a groundbreaking exercise routine to preserve the fitness of forthcoming moonwalkers. This new method involves navigating the inside of a Wheel of Death, typically found in circuses and amusement parks.
Running in Low-Gravity Conditions
A Wheel of Death typically comprises a large ring placed horizontally, where participants must maintain a certain velocity while running inside to evade gravitational forces and prevent falling off. On Earth, achieving this feat solely through human locomotion is nearly unattainable, necessitating a motorized vehicle like a motorcycle.
The Feasibility Experiment
For testing the viability of this exercise on the Moon, researchers in Milan conducted trials by suspending individuals inside a 30.8-foot Wheel of Death using bungee cords to simulate lunar gravity conditions. After several attempts, participants successfully ascended, ran along the wheel, and descended back to the ground.
Implications for Lunar Fitness Programs
The scientists’ analysis of the runners’ performance indicated that the exercise mirror Earth-like running conditions in terms of speed, stride length, and ground reaction forces. Consequently, the study authors suggested that moon-bound astronauts engaging in regular sessions on the Wheel could combat physiological deterioration effectively.
Future Adaptations for Lunar Habitats
While it’s unfeasible to transport an actual Wheel of Death to space, circular living modules could facilitate comparable running exercises for astronauts. This innovation aligns with anticipated lunar missions, such as Nasa’s Artemis program, aimed at lunar orbital and surface explorations.
Alternative Exercise Strategies
Amidst evolving fitness regimens for space travel, researchers like Prof Nick Caplan are exploring novel approaches, including blood flow restriction exercises, to mitigate muscular and cardiovascular decline in astronauts within limited space confines.
