Outcome
Primary Outcome Measures
1. Blind pulling error, i.e. difference between the actual position of the visual target and the final position of the subject between 1G, 1.8G, and 0G during parabolic flight and with blind pulling evaluation method [baseline]
2. Blind pulling error, i.e. difference between the actual position of the visual target and the final position of the subject between 1G, 1.8G, and 0G during parabolic flight and with verbal report evaluation method [baseline]
