摘　　要：目的探讨水下航行对潜水员的应激和免疫功能的影响。方法健康男性潜水员5名,在不同航速、不同深度、不同时间水下航行前后,应用美国国家航空航天局任务负荷指数量表评价其脑力负荷及紧张程度,应用放免法测定训练前后唾液皮质醇和分泌型免疫球蛋白A(sIgA)浓度的变化。结果 5名参试人员的主观心理负荷在训练深度增加到20 m时达到最高值;唾液皮质醇浓度在首次训练和深度增加到20 m时明显增高(P<0.05),而sIgA水平在各组间未显示明显变化(P>0.05)。结论水下航行对潜水员的应激作用随深度增加而明显增强,反复训练有助于人员应激水平恢复。Objective To investigate the effects of underwater navigation on the stress reaction and immune function in divers. Methods Brain load and stress reaction of 5 male divers working with different speeds,at different depths and different times both before and after underwater navigation were evaluated by using National Aeronautics and Space Administration-Task Load Index Scale. Changes in the concentrations of salivary cortisol and secretory immunoglobulin A（ sIgA） both before and after underwater training were detected by radio-immunoassay. Results The subjective stress load experienced by the 5 divers reached peak value,when they came to the depth of 20 meters. The concentration of salivary cortisol during the first underwater training and at the depth of 20 m was increased significantly（ P〈0. 05）,however,no significant changes in the concentration of sIgA could be noted between different groups（ P〉0. 05）. Conclusion Stress reaction experienced by divers during underwater navigation increased with the increase in depth,but repeated training was beneficial to the recovery of stress reaction.
