Study on the relationship between muscle fatigue and motion sickness responses in different sitting postures under ship rocking conditions.

In a ship rocking environment, muscle activity in different sitting postures may impact passenger balance and stability, thereby aggravating or alleviating symptoms of motion sickness. This study aims to explore the relationship between motion sickness induced by ship rolling and muscle activity in various sitting postures, with the goal of informing the optimization of ship seat designs to enhance passenger comfort. The research focuses on the angle of backrest inclination and head-neck position as key variables.
