An experiment on board an actual vessel was carried out with cadets who were boarding a training ship for the very first time as the subjects of the experiment. The pattern of motion sickneess incidence was one in which the incidence increased sharply during the periods the cadets were on watch, and sharply decreased during their free, off-watch periods. The vertical acceleration (rms) including heaving, rolling and pitching of the ship was taken as the magnitude of the periodic motion. The motion sickness incidence was divided into three grades, I (slight), II (moderate), and III (serious). Percentages of incidences in grade I or above (I+II+III), grade II or above (II+III) and grade III were obtained, and the linear relationship with the acceleration was found. In those cases where there was not much fluctuation in the acceleration, the incidence ratio attained its maximum two to three hours after exposure. It was also observed that acclimatization effects to periodic motion made themselves apparent by a reduction in the proportion of incidence ratio of motion sickness to acceleration as the number of aggregate days of the cruise increased.
