Why Space Exploration Stack Exchange recommends it

Space Stack Exchange users link it as visual evidence when discussing how astronauts move, exercise and affect a station's attitude in microgravity.

What it is

A short NASA archive clip, posted by the Discovery channel, showing Skylab astronauts in zero gravity. It features the "exercise wheel" running, playing catch, and the open interior of the station with its central cord.

This video [this video] may help to answer your question. Starting at about 00:24, you can see an astronaut running around the "exercise wheel" of Skylab (an early NASA space station program, which followed the Apollo moon landings). Basically after some time, NASA told the astronauts to stop running around like this because it was causing more propellants to be used to maintain Skylab's correct attitude (orientation) in space (at least this is what I've been told...it would be nice to find a reference to back this claim up). Anyways, the short answer is yes, an astronaut's physical activity within a spacecraft can absolutely affect its orientation and even its orbit. As to whether it is a large

Cites LocalFluff · 2016-11 · Space Exploration Stack Exchange · on “Would pole dancing cure microgravity health issues?”

It is often suggested that gravity should be simulated by rotating the entire habitat module of astronauts in microgravity. But wouldn't pole dancing be enough? The individual astronaut swinging around a pole stick, like a daring strip dancer/acrobat holding on to it with her hands while throwing herself around it with her body at 90 degree angle to it. An astronaut could maybe swing like this in a sleeping bag, or while doing some exercise. With minimal design requirements for the spacecraft. Wouldn't this be enough for the bodily fluids to learn about in what ends the head and the bottom are? We've got an example of a Skylab pole-artistronaut right here [this video] : [LINK]

In this Sky Lab [this video] video, one can actually see astronaut excercise in same way as you proposed. But, Suppose an astronaut jogs at about $2.5 m/s$ then by the centrifugal acceleration $$v^2/r$$ assuming, 6 m diameter of module, one gets slightly larger than $2 m/s^2$ acceleration. Which is much smaller than acceleration of $9.8m/s^2$ we are used to. Rather I think it will be much simpler and space efficient to use some waist belt to pull astronaut to treadmill for leg excercise.

After watching the video below (found here [LINK] and here [LINK] and here [LINK] ) I am reminded of the series of possibly less than 100% serious questions here about being weightless in the middle of a large volume and considering the options for reaction masses to get to the side and grab hold of something. In the video I noticed that there is a central cord or rope to hold on to, possibly for this very reason, or possibly it had a different function as well. What was this for? Gotta love the vintage music track, one of the zillion instances of the Amen Break [LINK] (original heard after 01:26 in The Winstons - Amen Brother [LINK] ).

Question: Is there some official or unofficial record for the longest time that an anstronaut remained in free fall, not holding on to or being secured by or pushed/nudged/impulsed by anything? This could b
