Hypogravity simulation using the Variable Gravity Suspension System: A technical report

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1580-1596, 1 April 2026.
Abstract Human movement has evolved within Earth's gravitational environment (1 g; −9.81 m s−2). Future human exploration of terrestrial bodies, including the Moon (0.17 g; −1.62 m s−2) and Mars (0.38 g; −3.71 m s−2), will require astronauts to live and work within reduced gravitational environments (hypogravity).
