![]() This gently lifts them off the treadmill which reduces pressure on the lower body. The reason anti-gravity treadmills can “manipulate” gravity comes down to the innovative “Differential Air Pressure” (DAP) technology that resists the effects of gravity.Īnti-gravity treadmills feature a bubble that inflates with air, then surrounds the user’s lower body. Strike force, cadence, stance duration, stride-length symmetry, and other complex statistics and data pertaining to the antigravity effect can all be monitored. Since antigravity treadmills are more technical than the typical treadmill, expect an in-depth console. Thus, the user is able to move at a speed between 100% and 20% of their body weight when walking or running. The springs will give the user the sensation of running or walking on air pressure, and the user can decide how high or low they want to go. It works by employing air pressure to make the body “weigh less,” counteracting gravitational forces.Ī system of pulleys and motors, which will be discussed in more detail later, produces this sensation when the user presses against the belt. The machine is designed for people to exercise with reduced load on their joints and muscles. It might sound like a contraption from a science-fiction movie, but an anti-gravity treadmill is just a piece of highly specialized equipment primarily used in physiotherapy practice. Chosen By The World’s Best Teams And Athletes.In the same year, the Whalen prototype was licensed to a company called AlterG, which seems to have come up with the term “anti-gravity treadmill.” For a nice image of this in action check out the AlterG treadmill featured here on Then, by flipping the air pump, thus, creating the opposite gravity effect, Sean designed the initial prototype of the anti-gravity treadmill as we know it today. Sean wanted to make it possible to lessen gravity on earth rather than increase it. Then around 2005, Sean Whalen, The treadmill that Whalen’s father had been testing was decided to be restarted. However, due to funding limits, NASA decided to pursue some of Robert’s other ideas, and his “air-pressure” controlled treadmill never really caught on. The astronauts could now recreate Earth-like conditions in space, however, thanks to the new device. With the previous devices, the astronauts could only train at roughly 60 percent of their body weight on earth. This, in turn, increased the astronaut’s apparent weight, allowing them to exercise at their normal earth weight. The astronauts’ lower bodies were initially enclosed in an airtight chamber where increased air pressure pushed them downward and created the illusion of gravity. Anti-gravity treadmills as a concept were thus created. Robert Whalen, a biomechanics researcher at the The NASA Ames Research Center was tasked with developing a system for astronauts to exercise inside the space station.Ī pressurized bubble that used air pressure to hold the astronauts down was one of the tools he created. And, God forbid, they would need to be in excellent shape in an emergency so they could escape the danger as soon as possible.Īdditionally, once the astronauts return to Earth, their weakened muscles and bones would make carrying any weight painful.įor these reasons, NASA (as well as other space agencies) has worked diligently over the years to develop strategies and tools to support astronauts’ physical well-being. ![]() This results in a loss of size and strength, and because it weakens the astronauts, it may compromise their ability to carry out tasks in space. Why is it important? Without physical exercise, their bodies, sooner than later, will start losing both muscle and bone density. The muscles and bones of these daring space explorers begin to atrophy without the literal pull of earth’s gravity.Īstronauts need to exercise regularly to make up for this loss in bone and muscle mass. ![]() An astronaut might spend three to six months in space on average, depending on the mission. Astronauts have been launched into space by NASA for more than 50 years.Īs missions got more complicated and technology advanced, astronauts were spending more time in orbit.
