Abstract: Objective To evaluate the effect of military performance stress on the changes of concentrations in salivary chromogranin A ( CgA) ,β-endorphin (β-EP) and salivary IgA ( sIgA) of submariners.Methods Twenty-nine submarine soldiers were selected, and their saliva samples were collected separately at the end of a long dive trip and nine months after relaxation ashore.In addition,the saliva samples of twenty-eight graduate students were collected as the normal control.The method of ELISA was used to detect the level of salivary CgA,β-EP and sIgA.Results After long-term dive training, the submariners showed significantly decreased CgA,β-EP and sIgA.Conclusion After a long term dive trip, chronic military performance stress is associated with the decline of salivary CgA,β-EP and sIgA, indicating that the function of sympathet-ic adrenal medulla is suppressed.The biological significance of these changes needs to be assessed in the future.
