Parabolic flight: Body weight estimates results. The experiment took place during a parabolic flight campaign on board the Airbus Zero-G aircraft (Airbus A310). Parabolic flight generates alternating periods of hypergravity (+1.8 g) and microgravity (0 g), each lasting approximately 20 sec. Baseline measures in terrestrial gravity (1 g) were performed on board the aircraft before and after the flight. Participants made absolute judgements in grams of the perceived weight of their own right dominant hand and head. Individual data are presented for both body parts and in function of the strength of physical gravity (0 g, 1 g, 1.8 g). Compared to terrestrial gravity, both hand and head weight estimates were reduced in microgravity and increased in hypergravity. Blue lines indicate individual averages and coloured shades represent standard deviations. Dotted lines indicate the linear fitting.
