目的通过动态观察间歇性低氧训练前后高性能战斗机飞行员EEG复杂度和血氧饱和度(arterial oxygen saturation,Sa()2)的变化特征,为低氧适应性训练效果评价提供量化指标.方法对32名高性能战斗机飞行员进行15 d的间歇性低氧训练(模拟高度3500 m),1次/d,每次25 min.于训练前后,分别检测受试者在模拟7500 m高空环境下的EEG、SaO2、红细胞数及血红蛋白含量,并对受试者低氧训练前后的检测数据进行t检验.结果间歇性低氧训练后,受试者在模拟7500 m高空环境下的EEG复杂度较训练前显著降低,差异有统计学意义(P＜0.01),Sa()2升高,差异有统计学意义(P＜0.01),红细胞和血红蛋白含量则无明显变化(P＞0.05).结论模拟3500 m间歇性低氧训练可提高机体高空缺氧耐力水平,EEG复杂度和SaO2可作为评价高性能战斗机飞行员间歇性低氧训练的定量生理指标.

Objective To explore the quantitative index for evaluating the intermittent hypoxia training effects by analyzing the characteristic changes of electroencephalogram (EEG) complexity and saturation of blood oxygen (SaO2) of high performance fighter pilots. Methods Thirty-two pilots were selected as subjects and undertook a 25 min-training (simulated hypoxia at 3500 m-oxygen concentration 13.1%) with Type DY-84 hypoxia training device once a day for 15 d. Before and after training the subjects were put in simulated 7500 m hypoxia condition (oxygen concentration 7.1%,ventilation volume 15L/min) and their EEG, SaO2, number of red blood cell and hemoglobin level were recorded and analyzed by t-test. Results Training effects showed that the subjects' 7500m EE(G complexity was significantly decreased (P＜0.01), but SaO2 was significantly increased (P＜0.01).Number of red blood cell and hemoglobin level had no obvious change (P＞0.05).Conclusions The simulated 3500 m intermittent hypoxia training could improve pilot's hypoxia tolerance. EEG complexity and SaO2, which are measured under simulated 7500 m hypoxia condition,would be the quantitative indices for evaluating the effects of intermittent hypoxia training for pilot.The results application would be hopefully expanded to the population who work at high altitude or in anoxic environment.
