Astronaut Resistance Training
« on: January 03, 2019, 04:56:39 PM »
I don't know much about space so I dont know if this is legit or not. Should make an interesting conversation either way!



This seems to be a pretty comprehensive system. I imagine it or some other way of trying to retain muscle mass and strong cardiovascular function away from Earths gravity must be very important.

Is this a system that is in use?

Any videos of other systems?

Why does the bracing surface need to move with each rep? Surely this steals some of the workload from the astronaut?

Why was a bar and some springs with a solid bracing surface not used?

I am 99.99% sure 99.99% of you know the answers so please share!

It looks legit to me. I’m confident it is real. As to why they designed it this way and not some other way, I have no idea, but I’m sure a lot of research and testing was involved. The astronauts do cardio training also.

And even with all the cardio and resistance training, astronauts lose a lot of bone and muscle mass, so much so that when they return to Earth after an extended period in space, they can neither walk nor stand. Microgravity is absolute hell on the human body. Just one more reason I’m planning on remaining on the planet.

I've seen the Bungee Banditos in videos. Fun to watch while sipping a beer.

Oh Im sure the research dictated this approach to a seemingly simpler one!
Im just hoping to learn why. Especially why they arent bracing against an immobile surface!

Physical therapist have given me no end of bungee-related exercise gear.

The Advanced Resistive Exercise Device (ARED) uses adjustable resistance piston-driven vacuum cylinders along with a flywheel to system to provide loading for crew members to experience load and maintain muscle strength and mass during long periods in space.

I saw a video about the design of this thing a while ago. It uses vacuum instead of elastics to better simulate resistance due to gravity. I'm not sure why it is built to move about.

ETA it also uses a flywheel system. Interesting read.

I’m just guessing that it really doesn’t matter whether one surface remains immobile or not. What matters is the amount of resistance, which I’m sure can be adjusted for the strength of the individual.

It seems that the exercise done in zero gravity only slows the deterioration of the body, not a real fix.  Could be trouble on a trip to Mars.

This is absolutely true. Astronauts do rigorous exercise, both cardio and resistance, while in space, and still, after lengthy stays in space, they have lost significant bone mass and they have to be carried out of the re-entry vehicle on stretchers. Then they have lengthy periods of physical therapy to be able to handle life on Earth again. I think I’ve read that they never really recover entirely, but I’m unsure about that part.

Problem is going to be, when they get to Mars, there won’t be anybody to carry them out of the lander and into the habitat that presumably will have been built ahead of time by robots, because they sure won’t be in any shape to build anything when they get there. (Just one more inaccuracy of The Martian.) I guess the robots will carry them. And then do all the work they’ll be too weak to do.

Nevermind
and Donald Trump is President of the United States.

I'm not a doctor, I'm just someone who has done a ton of research into diet and nutrition.

A spinning ring would do it. It would be a lot of mass to move, but then, you're going to need to move a lot of mass anyways.

Just for fun, the reason I have an opinion on this is because of a SF game I run. (Morvis has a character in it.) After doing a lot of reading about radiation shielding, materials science, ion drives, life support, and more, I came up with an experimental prototype belt mining ship that is meant to keep a dozen people alive indefinitely.

Most of the tech extrapolates from existing materials and energy densities without requiring anything absolutely new. Life support might be the most difficult part.

Larry Niven, IIRC, proposed a hollowed out asteroid as a place for women to produce more asteroid miners. It was to be spun to close to Earth normal. I would think that a purpose built unit would be more efficient. Anybody read "The Man Who Ran Around the World"?

I don't think I've read that one. I have read a LOT of Niven though, and it has affected my thinking. The game does have a hollowed out asteroid - but that's alien tech, not human. :)
