Fig. 2: Arm kinematics.
From: Hypergravity is more challenging than microgravity for the human sensorimotor system
A Illustration of arm angular elevation during reaching toward the far target. (B, E, H) Movement velocity as a function of experimental conditions. (C, F, I) Arm peak velocity, (D, G, J) and relative time to arm peak velocity as a function of (B–D) Environment, (E–G) Target, and (H–J) Perturbation. Environment was microgravity (0g), hypergravity (1.8g) or normogravity (1g). Participants either had to reach toward a close or a far target. On 20% of the trials, an electromagnet was switched on and participants had to adjust motor commands to reach the target. Error bars represent standard deviation. *P < 0.05, **P < 0.01.
