New ‘Space Hopper’ Device Allows Astronauts to Spend Less Time Exercising in Space

November 21, 2019

This is another story from yesterday’s I, this time about a new development in space research. At the moment astronauts have to spend over an hour a day exercising in order to combat the harmful effects of zero gravity. Without the pull of the Earth’s gravity, their muscles waste, including the heart. They also have to take care to try to prevent the loss of calcium from their bodies, which weakens their bones. But now inventor John Kennett has invented an exercise machine that allows them to do many of the exercises at once, thus cutting down drastically the amount of time they need trying to maintain a level of fitness.

Keeping healthy in space is so vital that astronauts typically spend up to 90 minutes a day doing vigorous exercises.

But that could be about to change thanks to a new “jumping machine” that will gie them the same physical benefit in three or four minutes, according to its inventor.

Without effective exercise, astronauts’ fitness would quickly decline and their muscles and bones would lose strength.

At the moment, they spend much of their space-day running, cycling and doing strength training – on equipment that takes up a lot of valuable room and can take up to an hour to set up and dismantle.

According to the inventor John Kennett, his machine replaces the existing regime with a smaller, all-in-one device that boosts muscle and bone strength and provides cardiovascular exercise at the same time. it is 1.3 metres long and 20 centimetres thick when folded to be stowed.

The bed has a board that presses up against the bottom of the astronaut’s feet. This exerts a force that replicates the motion of jumping and is a highly effective form of exercise that can be varied to work different parts of the body.

“This piece of equipment has the potential to change the way astronauts travel through the solar system,” Mr Kennett said.

“The equipment they use at the moment is based on being in the gym – things like dead lifting or bench pressing. This is good but, when you jump, you do something incredible effective to the muscle and the tendons because you’re absorbing the landing force and then pushing away,” he added.

The device, known as the High Frequency Impulse for Microgravity, has been specially designed to eliminate vibrations and forces that would normally apply to exercise equipment but have the potential to damage spacecraft.

There’s also an additional snippet reporting that the UK space agency has given St Mary’s University in Twickenham a grant to conduct further research on Kennett’s invention after initial tests proved promising.

This is really interesting, and could be a great step forward. But I’ve heard rumours of breakthroughs in tackling the effects of Zero G on the human body before. About twenty or so years ago I went to see the British expert on space medicine, Dr. Kevin Fong, talk about the some of the problems space causes on astronauts’ physical and mental health. He believed that these problems were near to being solved through a device, a vibrating plate, that astronauts would stand on. I haven’t heard anything about this since, so I presume it didn’t work. But the inclusion of a fixed plate for the bottom of the astronaut’s feet in this decision also suggests that the previous invention made have played a role in the development of this device. And if this does prove effective in combating zero G, it will be a great help in allowing humans to cope better with the long interplanetary voyages necessary to open up and hopefully colonise the solar system.
