Objective To study the effects of different physiological function status on anti-seasickness ability, in order to provide the theoretical basis for the adaptability training.
Methods Fifty-four male subjects were divided into 3 groups randomly. The one named sleep-deprivation group who resisted the dizzy simulation experiment after depriving their sleep for 28 hours, the other one named exercise-induced fatigue group who also resisted the same experiment after 5 kilometers armed crosscountry training and the third named control group did the experiment in their normal quiet condition.
Results The incidence of seasickness was 88.9% in the control group, but 100.0% in the sleep-deprivation group and in the exercise-induced fatigue group. The incidence of mild seasickness was 33.3% in the sleep deprivation group and 27.8% in the exercise-induced fatigue one, significantly lower than that in the control group (55.6%) (P<0.05). The incidence of severe motion sickness was 38.9% in the sleep-deprivation group and 33.3% in the exercise-induced fatigue one, significantly higher than the control group (11.1%) (P<0.05). After resisting the dizzy simulation experiment, the RBC-AChE was (21.76& #177;4.85)kU/L in the sleep-deprivation group and (23.71& #177;2.42)kU/L in the exercise-induced fatigue one, significantly lower than that in the control group(, 25.29& #177;2.70)kU/L (P<0.05). The content of Ang Ⅱ in all the test groups had no statistical significant difference with control group.
Conclusion The sleep deprivation and sport induced fatigue can weaken the ability of anti-seasickness. The personnel in training for antiseasickness should have enough sleep and master a variety of ways and means to eliminate fatigue.
