目的]观察心理干预及体能增进剂对高强度军事训练战士疲劳程度和心理状态的影响。方法]将39名战士分为实验组与对照组，分别给予体能增进剂和安慰剂，在试验前1d以及第8天进行疲劳评定量表（FAI）评定并记录战士的疲劳主诉，应用SAS、SDS自评量表对战士进行心理干预前后测试，并且进行疲劳程度对焦虑、抑郁影响的相关性分析。结果]实验组试验后FAI因子1（疲劳严重程度量表）得分较对照组显著降低，战士的疲劳主诉明显减少；干预后SAS、SDS总分均低于干预前（P〈0．05或P〈0．01）；实验后FAI因子1与干预前SAS、SDS评分均有相关性（P〈0．01）。结论]体能增进剂可以降低高强度军事训练状态下战士的疲劳程度，并且通过营养干预联合系统的、有针对性的心理干预后，战士的焦虑、抑郁症状得到改善。

Influence of psychological intervention and physical ability enhancing agents on fatigue, anxiety and depression of soldiers after high -intensity training

Objective.To observe the influence of psychological intervention and physical ability enhancing agents on fatigue degree and mental state of high - intensity training of soldiers. Methods. A total of 39 soldiers were divided into test group and control group randomly. Soldiers of test group were given physical ability enhancing agent. And soldiers of control group were given the placebo. The complaaints of fatigue of all soldiers were recorded and evaluated by fatigue assessment instrument （FAD on the 1st day before the test and 8th days after the test respectively. Then anxiety and depression of all soldiers were as- sessed before and after psychological intervention by adopting SAS and SDS. Finally correlation analysis between the fatigue degree and anxiety and depression of all soldiers were completed. Results. After the test,the factor 1 of FAI and the feeling of fatigue of test group soldiers were significantly lower than that of control group soldiers. The total SAS and SDS scores of all soldiers after psychological intervention were significantly lower than that of before the intervention （P〈0.05 or P〈0.01）. And after the test,it showed a significant correlation between the factor 1 of FAI and scores of SAS and SDS of soldiers before the intervention （P〈0.01）. Conclusion. Physical ability enhancing agent can alleviate the fatigue of soldiers in high - intensity military training. Eudl anxiety and depression of soldiers could be improved by nutritional intervention in combination with systematic and targeted psychological intervention.
