摘要
目的探讨首次急进高原士兵觉察压力、睡眠状况与疲劳状况的关系,分析睡眠状况在觉察压力与疲劳状况间的中介作用和调节效应。方法采用方便抽样方法,抽取700名首次急进高原的士兵为研究对象,采用《觉察压力量表》、《睡眠状况自评量表》和《疲劳量表-14》进行调查。中介作用采用结构方程模型分析,调节效应采用分层回归分析。结果经常参加娱乐活动的士兵疲劳总分低于不经常参加娱乐活动者(P<0.01);有训练伤的士兵疲劳总分高于无训练伤者(P<0.01);训练期望高的士兵疲劳总分高于训练期望一般和无所谓者(P<0.01)。睡眠状况、超载感与训练期望均对首次急进高原士兵疲劳状况有显著预测作用(P<0.01)。睡眠状况在预测感、超载感与疲劳状况间具有完全中介作用(P<0.01),睡眠状况在控制感、超载感与疲劳状况间具有调节作用(P<0.01)。结论觉察压力、睡眠状况与首次急进高原士兵疲劳状况有密切关系;睡眠状况在超载感与疲劳状况间有中介作用和调节效应。
Objective To investigate the relationship among perceived stress,sleep and fatigue status; and to analyze the effect of sleep status in mediating and regulating perceived stress and fatigue status in soldiers that were acutely exposed to high altitude for the first time. Methods A total of 700 soldiers that were acutely exposed to high altitude for the first time were investigated with convenient sampling. They were evaluated using Perceived Stress Scale,Sleep Status Self-evaluation Test,and Fatigue Scale-14. The mediating effect was analyzed by structural equation model,and the moderating effect was analyzed by hierarchical regression analysis. Results The total score of fatigue among soldiers that often took part in recreational activities was significant lower than that who did not( P〈0. 01). The total score of fatigue among soldiers that had training injury was significant higher than that who had not( P〈0. 01). The total score of fatigue among soldiers that had high training expectations was significant higher than that that didn't have high training expectations( P〈0. 01). Sleep status,sense of overload and training expectations had remarkable predicting effect on fatigue status among soldiers that were acutely exposed to high altitude for the first time( P〈0. 01). Sleeping status has a complete mediating effect on the sense of prediction,sense of overload and fatigue status( P〈0. 01),and has a moderating effect on the sense of control,sense of overload and fatigue status( P〈0. 01). Conclusions Perceived stress and sleeping status had close relationship with fatigue status among soldiers that were acute exposed to high altitude for the first time. Sleeping status has intermediary and regulating effect between senses of overload and fatigue state.
