Weightless Posture Device

SpaceFIT | Projects

  • Our project is a harness that one would wear in space to prevent the atrophy of muscles in one's core specifically the lower back muscles and the abs. There are two pieces on that is worn on the lower back and one that wraps around the butt and thighs. Elastics are attached to the both pieces and the elastics sort of simulate gravity. The elastics want to pull your upper body and lower body together so you are forced to use your core muscles to keep your upper and lower body apart. In space because there is no gravity one's muscles and posture begin to deteriorate because they are not be used. We decided we wanted to come up with a device that would passively stimulate one's core muscles so they don't deteriorate. This project is important because on average astronauts loose thirty percent of their muscle mass while in space and this beomes a health risk for them. Since astronauts loose so much muscle mass in space they are forced to spend two hours working out everyday, our project attempts to lessen the amount of time they have to work out because it forces them to passivly use their core muscles.

  • Inspiration:


    The main problem that we were faced with was muscle atrophy in space, or the the weakening of muscles due to lack of use. We decided to focus on preventing atrophy in the core muscles, and we intended on creating a device that would help astronauts in maintaining their core strength while in space.


    Iteration 1:


    Our first design idea was to create a chairlike device that applied pressure on the user’s back. WIth a constant pressure applied to the back, the user is forced to flex their core muscles. The chair could apply a pulling force, or a collapsing force on the user—both triggering different muscles.


    Iteration 2:

    We decided to create a device that an astronaut could wear instead of creating a ‘seat’. The device would consist of two separate pieces—one attached to the upper body, and one to the lower body—and elastics that would provide resistance.
