Evidence that humans underestimate body mass in microgravity: kinematic signatures in reaching movements during spaceflight
Zhaoran Zhang, Yu Tian, Chunhui Wang, Changhua Jiang, Bo Wang, Hongqiang Yu, Rui Zhao, Kunlin Wei
The paper shows astronauts' reaching movements slow in microgravity due to underestimated body mass, not strategic slowing, with kinematic changes linked to sensorimotor adaptation.
